The nation’s interstate commercial motor carrier industry is extensive and includes a number of stakeholders, including carriers, shippers, receivers, and intermediaries. Motor carriers are companies or individuals that transport cargo using motor vehicles. According to FMCSA officials, there are about 737,000 interstate carriers registered with FMCSA. While the largest motor carriers operate upward of 50,000 vehicles, approximately 80 percent of carriers are small independent-owner operators or trucking companies, operating between 1 and 6 vehicles. Within the industry, there is a variety of types of carriers. For example, carriers are either for-hire, transporting cargo to the public on a fee basis, or private, running a vehicle fleet to transport only the company’s own products. There are also two principal classes of for-hire carriers: truckload carriers transport a single shipper’s cargo between two locations, while less-than-truckload carriers transport cargo for multiple customers that may require pick-up or delivery at multiple locations. In addition, some carriers primarily provide long-haul service—which is generally considered to be intercity service—while other carriers primarily provide service within a metropolitan region, referred to as short haul. Finally, carriers use vehicles that differ by body types—including dry trailers, refrigerated trailers, flat beds, and tank trailers—some of which can carry a variety of cargo, while others are used for only one type of cargo. (See fig. 1 for examples of vehicles.) Shippers are the cargo owners that hire the carriers to transport their cargo. For example, a shipper could be a product manufacturer that hires a carrier to transport its product from the manufacturing plant to the end customer, or a retail company that hires a carrier to pick up its finished products, such as clothing or electronics, from a seaport terminal or other location for transport to a distribution center. Receivers are those who are scheduled to receive and take ownership of the cargo. The receiver could be the customer of the shipper, such as a retail company or manufacturing plant, which takes ownership of the cargo to sell or use in a production process. Intermediaries arrange for the transportation of goods between the shippers and receivers. For example, a freight forwarder acts as an agent on the behalf of the shipper and will consolidate shipments from several shippers and then contract with carriers to transport these shipments. In addition, a freight broker will arrange the pick up and delivery of a shipper’s good by a carrier without having physical control of the cargo. Third-party logistical companies provide warehousing and supply chain services for the shippers and can arrange transportation of the shippers’ products. For example, carriers could transport cargo to a third-party distribution center, which can repackage the cargo for further distribution. Figure 2 provides a description of the steps typically involved in moving cargo through the system. The decisions of the various stakeholders—carriers, shippers, receivers, and others—direct the logistics (or operation) of the interstate commercial motor carrier industry, and consequently can affect the occurrence and amount of detention time. Each stakeholder plans and organizes its own activities within this large industry in an effort to meet its critical objectives. Carriers attempt to minimize their travel time and the miles they drive with no cargo, while at the same time meeting the needs of shippers. Shippers try to minimize the costs of their transportation needs while ensuring delivery in a timely manner. As each stakeholder makes its own logistical decisions, it faces tradeoffs in the costs and benefits of various options for how to schedule and manage resources. Given the numerous activities that need to be scheduled and coordinated within the industry on a daily basis, some level of trucker detention time is expected. If a shipper provides its own trucking services through a private fleet, one of the shipper’s goals will likely be to schedule shipments in a way that minimizes detention time and thus increases productivity. However, if, for example, an on-time pick up is a high priority for a particular shipment, then the shipper may choose to schedule a truck to arrive early, thus potentially increasing the likelihood or amount of detention time. Conversely, when a shipper uses a for-hire carrier, the shipper may be less inclined to fully take the extent of detention time into consideration when making its scheduling decisions because the shipper does not fully bear the costs of the detention time it may impose on truckers. Therefore, some detention time in the industry likely results because shippers’ and receivers’ decisions can affect the extent of detention time, but the costs of detention time are largely born by truckers. The federal role in regulating the interstate commercial motor carrier industry has changed over time, as shown in figure 3. Currently, the federal role in the industry is focused on regulating safety aspects of the trucking industry and funding transportation infrastructure, which are managed by two agencies within DOT. FMCSA’s primary mission is to prevent commercial motor-vehicle-related fatalities and injuries. It carries out this mission by issuing, administering, and enforcing federal motor carrier safety regulations—including hours of service requirements—and gathering and analyzing data on motor carriers, drivers, and vehicles, among other things. FMCSA also takes enforcement actions, and funds and oversees enforcement activities at the state level through Motor Carrier Safety Assistance Program grants. FHWA is responsible for overseeing the federal-aid highway program, which funds highway infrastructure. Within FHWA, the Office of Freight Management and Operations is tasked with promoting efficient, seamless, and secure freight flows—including freight transported by the interstate commercial motor carrier industry—on the U.S. transportation system and across the nation’s borders. The office advances its mission by building a greater understanding of freight transportation issues and trends, improving operations through advanced technologies, and educating and training freight transportation professionals. The office also conducts operational tests of intelligent transportation system technologies and promotes the development of standards for freight information exchange. Federal hours of service regulations place restrictions on operations of a property-carrying commercial motor vehicle driver by setting limits on duty periods. There are three hourly limitations for these drivers, including a 14-hour “driving window” after coming on duty following 10 consecutive hours off duty, 11 hours of which can be “driving time,” and a prohibition on driving after 60 or 70 hours of on duty time per week, with certain exceptions and exemptions. Specifically: 14-hour “driving window”: A driver is allowed a period of 14 consecutive hours after coming on duty, following 10 or more consecutive hours off duty, in which to drive. This 14-hour period begins when the driver starts any kind of work or is required to be in readiness to work, and once the driver has completed the 14-hour period, the driver cannot drive again without first being off duty for at least 10 consecutive hours. The 14-hour period covers both on duty and off duty time. 11-hour driving limit: During the 14-consecutive-hour driving window, the driver is limited to 11 total hours of actual driving time. The 11 hours can be consecutive or nonconsecutive within the 14-hour period. 60/70-hour on duty limit: A driver is required to adhere to one of two duty hours weekly limits, which is specified by the driver’s carrier. A driver may restart the 60- or 70-hour “week” by taking at least 34 consecutive hours off duty. If a driver’s carrier (employer) does not operate commercial motor vehicles every day of the week, the driver may not drive after being on duty 60 hours during any 7 consecutive days. If a driver’s carrier does operate commercial motor vehicles every day of the week, a 70-hour/8-day schedule is permitted. The driver may not drive after being on duty 70 hours in any 8 consecutive days.” A driver may restart the 60- or 70-hour “week” by taking at least 34 consecutive hours off duty. According to hours of service regulations, on duty time includes all of the time from when a driver begins work for a motor carrier or is required to be in readiness to work by that motor carrier, whether paid or not, until the time the driver is relieved from work and all responsibility for performing work. Some examples of on-duty time may include: driving time, to include all time spent at the driving controls of a commercial motor vehicle in operation; time at a plant, terminal, or other facility of a motor carrier or shipper, or on any public property, waiting to be dispatched; time loading, unloading, supervising, or attending the truck or handling receipts for shipments; and all other time in or upon a commercial motor vehicle unless the driver is resting in a sleeper berth. Federal hours of service regulations require drivers to maintain a “record of duty status”—commonly referred to as a driver’s log, daily log, or log book—either in written form or electronically using an automatic or electronic on-board recording device. Drivers must account for all hours of every day in their log, including days off, and must also have a log for each day of the last 8 days they were required to log. One means to ensure compliance with various safety requirements, including hours of service, is for authorized FMCSA and state officials to conduct driver and vehicle inspections of commercial vehicle motor carriers. During certain types of inspections, these inspectors check the drivers’ logs for compliance with hours of service regulations. If the inspector finds that a driver has not complied with the hours of service regulations, the violation can result in a driver being fined and/or being placed out of service. In addition, FMCSA ensures that motor carriers comply with safety requirements through compliance reviews of carriers already in the industry and safety audits of carriers that have recently started operations. Compliance reviews and safety audits help FMCSA determine whether carriers are complying with federal safety requirements—including hours of service regulations—and, if not, to take enforcement action against carriers, including placing carriers out of service. While there are no industry-wide data providing information on the occurrence of detention time, interviews with drivers, industry representatives, and motor carrier officials indicate that detention time occurs with some regularity. During our structured interviews with truck drivers, we found that the majority of these drivers had experienced detention time within the last month. Overall, 204 of the 302 drivers interviewed—about 68 percent—had reported experiencing detention time within the last month. Most of these drivers—178 of the 302, or about 59 percent—reported experiencing detention time within the last 2 weeks. About 11 percent of the drivers—32 drivers—reported they last experienced detention time more than 1 month ago. For those drivers that reported previously experiencing detention time, the amount of detention time ranged from less than 2 hours to over 8 hours, and occurred at a variety of different facilities, including production facilities and distribution centers. Finally, about 22 percent of drivers reported they had never experienced detention time. In addition, a number of motor carrier officials stated that their truck drivers experience detention time regularly enough to institute systems to track detention time for their individual companies. For example, officials from one company that tracks detention time noted that their drivers experienced detention time on 12 percent of deliveries over a 3-month time period. While detention time can happen to all types of carriers, several industry representatives noted that drivers of some vehicle types experience a higher degree of detention time, while drivers of other types do not typically experience as much detention time. For example, some industry representatives noted that refrigerated trailer drivers tend to experience detention time to a greater extent than others because refrigerated trailers can maintain cargo at the required temperature, and can therefore wait for cargo from other nonrefrigerated trailers to be unloaded. In some cases, drivers with refrigerated trailers have had to wait overnight in order to keep the product stored at the proper temperature until it could be unloaded the next morning. In contrast, while tanker trucks can experience detention time, some industry representatives noted that tanker truck drivers do not typically experience as much detention time as some other types of trailers. Truck drivers, industry representatives, and company officials identified several factors that can contribute to detention time. Based on our interviews, the 236 drivers that had reported previously experiencing detention time—either within the last month or more than 1 month ago— facility limitations, arriving for a scheduled pick-up and finding the product was not ready for shipment, poor service provided by facility staff, and facility scheduling practices were the most frequently cited contributing factors. Other stakeholders also cited these same factors as contributing to detention time. Facility limitations: About 43 percent of drivers reported they experienced detention time because the facilities were not adequately staffed, lacked sufficient loading and unloading equipment, or had an insufficient number of bays for loading and unloading trucks. These limitations can occur, for example, when facilities overschedule appointments for pickup or delivery or do not have enough staff or equipment to handle the number of trucks scheduled, thereby creating a backlog of vehicles that need to be loaded or unloaded. Product not ready for shipment: About 39 percent of drivers reported they experienced detention time because the product was not ready for shipment when they arrived at the facility for pick up. This could be due to a number of reasons, such as manufacturing problems that delayed the production of the finished product. Industry representatives and company officials also highlighted that fresh produce often is not ready for shipment when drivers arrive at the loading facility. For example, one reason fresh produce might not be ready for shipment is that weather, such as heavy rains, can delay harvesting and packaging of the produce for shipment before the drivers’ scheduled pick-up time. Poor service provided by facility staff: About 39 percent of drivers reported that poor service by the facility staff was the reason they experienced detention time. Some drivers stated that once they arrived at the facility, the facility staff were indifferent to the drivers’ schedules and would take their time before starting the loading or unloading process. Scheduling practices: About 34 percent of drivers reported that facility scheduling practices at some facilities led to detention time. One of these scheduling practices cited by industry representatives was a “first come, first serve” system, in which the facility loads the vehicles in the order of arrival at the facility. For example, some seaport terminals use this system, which results in drivers lining up at the gate to the terminal before the facility opens to make sure they can get their containers as quickly as possible. The time waiting at the gate is not considered detention time by the terminals. Other factors: Drivers, industry representatives, and company officials noted there are some other factors not under the control of the facility that can contribute to detention time. For example, about 6 percent of drivers we interviewed reported that the driver was responsible for the detention time due to the driver’s paperwork not being in order. In these cases, the facility would either have to push back its overall schedule, potentially impacting all truck drivers scheduled for loading and unloading at that facility that day, or have the delayed driver wait for an available opening. Some company officials also noted that loading or unloading could be delayed if the driver is not familiar with either the shipper’s facilities or its loading and unloading procedures. Two other factors cited by officials include shipping facility staff calling in sick and leaving the facility short of staff, and a breakdown in loading or unloading equipment, which can have a cascading effect on the facility’s schedule. Shippers may implement practices to reduce detention time at their facilities. Some shippers have established appointment systems, which allow the facility to better manage available bays, staff, and loading equipment. For example, one facility we visited schedules carriers to arrive every 30 minutes, with a goal of having the carrier either loaded or unloaded within 90 minutes. If a carrier misses an appointment, the facility will unload that carrier whenever possible, but will not bump another carrier that makes the scheduled appointment time. Another practice to reduce detention time is to use technology, such as improved communication and vehicle inspection technology, to improve the process. For example, some seaport terminal operators have installed video cameras at the gate to speed up the process for inspecting the cargo containers as trucks enter the facility. This practice reduces the wait time at the facility’s front gate. Detention time can impact drivers’ ability to make scheduled deliveries within the hours of service requirements by putting drivers behind schedule and reducing available driving time. For those drivers that reported previously experiencing detention time, 80 percent reported that detention time reduced their available driving time. For example, some drivers noted that since the federal hours of service regulations allow them a “driving window” of no more than 14 consecutive hours—limited to 11 hours of driving time—detention time can significantly reduce the available driving window and driving time. Therefore, if a driver experiences 6 hours of detention time, that driver can only drive for 8 hours, at most, before being required to rest for 10 hours. Some drivers noted that this could delay their next scheduled delivery and, in some cases, result in the receiver charging the driver a late delivery fee. According to industry representatives, drivers who experience detention time and lose available duty and driving time may sometimes be faced with a choice of not making their scheduled delivery time, violating the speed limit, or violating the hours of service requirements to make up for lost time. Detention time can in some cases lead drivers to operate their vehicles beyond the hours of service requirements and improperly log duty time in order to make scheduled deliveries on time. When asked how detention time impacts them, about 4 percent of drivers responded they have driven beyond the hours of service limits and misrepresented their hours in their log books. Although we did not specifically ask the question during the structured interviews, a number of drivers we spoke with stated they kept multiple log books in order to disguise incidents where they violate hours of service requirements due to detention time. Detention time can also result in lost revenue for drivers, as well as carrier companies. Based on our structured interviews, of those drivers that reported previously experiencing detention time, 65 percent reported that detention time had caused them to lose pay. According to industry representatives, the lost revenue can result from either missing an opportunity to secure another load or having to pay late fees to the receiver. Detention time has a greater potential to result in lost revenue for independent owner operators than drivers employed by carrier companies. In general, drivers that are employed by private companies are paid by the hour. Owner operators—including owner operators that are leased to carrier companies—are typically paid by the number of miles driven or by the number of loads delivered. Because the typical owner operator’s pay structure is based on actual driving time, these drivers do not get paid for time spent waiting to load or unload. In fact, drivers have an adage that says “when the wheels ain’t turning, you’re not earning.” Carrier companies have some ability to mitigate the economic effects of detention time through a variety of means, such as charging detention fees to shippers, developing relationships with customers, using efficient loading and unloading operations, and no longer providing service to customers with persistent detention time. First, according to vehicle safety association officials, larger carrier companies have the leverage to include detention fee clauses in their contracts with shippers. For example, a number of carrier companies we talked with charged detention time fees to the shippers for any time over 2 hours that their vehicle was at the facility. The detention time fee varied based on the specific contract; examples provided to us ranged from $40 to $80 per hour. Based on our structured interviews, 53 percent of drivers that reported previously experiencing detention time reported that their company collected detention fees. However, according to some carrier officials, not all carriers collect detention fees, even if provided for in the contract, due to their reluctance to charge their customers, particularly their larger customers with whom they conduct significant business. One carrier official explained that detention time is simply a cost of doing business in today’s freight environment. In addition, collecting detention time fees can sometimes be challenging if the shipper does not agree with the amount of detention time that occurred. For example, during a 3- month time period, one carrier billed over $4,300 in detention time fees but received less than $500. Second, some carriers work closely with their customers to reduce detention time. According to industry representatives, some carriers develop relationships with shippers and receivers as they make routine visits to their facilities and establish a familiarity with the process. For example, according to one motor carrier company, its work with customers to track and measure detention time information has, in many situations, resulted in some decrease in detention time. Third, some carriers use a more efficient loading and unloading operation called the “drop and hook” method, which limits detention time. Drop and hook operations prevent the driver from having to wait for a trailer to be loaded or unloaded at the shipper’s facility. The driver will arrive at the facility with an empty trailer, drop off the empty trailer, and hook up the loaded trailer. The shipper will load the cargo into the trailer prior to the scheduled pick-up time. According to company officials and industry researchers we spoke to, the drop and hook method does reduce detention time. However, according to carrier officials, drop and hook requires the carrier to invest in additional trailers. For example, one carrier that used the drop and hook method had 1.5 trailers for each tractor, resulting in additional costs to purchase and maintain the trailers. Finally, some motor carrier officials stated that if they experience significant occurrences of detention time at a particular facility, the carrier could stop providing transportation services for that client if it had sufficient business with other shippers. In addition, some larger carrier companies are better able to handle logistical challenges that could result from detention time. For example, a carrier may have one of its vehicles held up because of detention time; however, a larger carrier can adjust the schedule of other vehicles to ensure the carrier is able to meet its commitments, therefore limiting the impact of the detention time. Smaller carrier companies or independent owner operators with only a few vehicles may not be able to react in a similar manner. According to industry representatives, independent owner operators have limited ability to mitigate the economic effects of detention time. For example, some industry representatives stated that since independent owner operators that do not lease on a regular basis to carrier companies generally use intermediaries to arrange for cargo, those operators do not have established contracts with shippers and thus have less leverage to charge detention time fees. Depending on their contractual arrangements, independent owner operators that are leased by a large carrier also may not receive detention time fees, even if the motor carrier charges and collects those fees. In addition, even if an independent owner operator that is leased by a motor carrier receives detention fees from the motor carrier, the fees may not fully compensate the driver for the detention time. That is because detention time compensation typically falls short of the amount of compensation that drivers would receive when they are actually driving since most of their compensation is based on miles driven. Finally, according to an industry representative, some carrier companies opt to send drivers from leased independent owner operators—who, unlike some carrier companies’ own drivers, are not paid by the hour—to facilities that frequently cause detention time. In so doing, the motor carrier does not have to pay the driver for the time spent waiting to load and unload. Furthermore, in some cases, independent owner operators do not transport cargo to the same facilities as frequently as carrier companies, which limits a driver’s familiarly with the procedures of specific facilities and could lead to detention time. For example, according to one warehouse representative we talked with, the drivers that encounter the most detention time are associated with independent owner operators that are not familiar with the requirements and rules of the facility, which includes not having the proper paper work, enough fuel for their refrigerated trailer, or the trailer is not in the proper condition. That representative’s facility will not check in trucks that do not meet these core requirements. Finally, independent owner operators generally do not have the financial resources to purchase additional trailers to take advantage of the drop and hook method or to simply absorb the costs of detention time. Although FMCSA collects data from roadside inspections, which provides information on the number of hours of service violations, the agency currently does not collect—nor is it required to collect—information to assess the extent to which detention time contributed to these violations. In 2009, FMCSA and state officials conducted over 3.5 million roadside inspections of interstate and intrastate motor carriers and almost 6 percent of these inspections resulted in at least one out-of-service violation. As shown in table 1, according to FMCSA data, hours of service violations were among the top 10 cited out-of-service violations. Specifically, violations of all three types of hours of service requirements—the 14-hour “driving window” rule, 11-hour driving rule, and 60/70-hour weekly on-duty rule—ranked in the 10 most frequently cited types of violations. Further, according to FMCSA officials, 14-hour rule violations were the most common out-of-service violations from U.S. roadside inspections in 2009, as well as in 2007 and 2008. FMCSA officials stated that 14-hour rule violations are straightforward and easier to detect during roadside inspections compared to other types of violations, which partially explains the more common occurrence of this type of violation. While FMCSA does not collect information on what factors contribute to hours of service violations, officials and industry representatives stated that detention time could be one of many such factors. Other factors could include a driver needing to leave the property of a facility and drive to a parking or rest area a number of miles away, having already used up the available driving hours for that day. Because FMCSA does not currently collect and analyze data on the factors that contribute to hours of service violations, its ability to assess the impact of detention time on hours of service violations, which may affect driver safety, is limited. Agency officials stated that, while FMCSA does not identify the factors that contribute to out-of-service violations, including hours of service violations, during roadside inspections, inspectors may acquire some information on these factors during compliance reviews. However, agency officials also stated they do not currently have other data that would help them determine either how often detention time occurs or how often detention time contributes to drivers violating hours of service requirements. For example, driver log data that FMCSA reviews during inspections—either in hard copy or electronically—do not include or identify detention time. While drivers are not required to specifically note detention time in their log books, they must note the time they arrived and departed a facility. However, if the driver did experience some detention time with the recorded time at the facility, it does not necessarily mean that it was a contributing factor to a violation in hours of service. To make that determination, an inspector would have to ask the driver what happened. As a result, it may be difficult to link hours of service violations to detention time based solely on log book data. To date, research conducted by FMCSA has not specifically included efforts to determine the extent to which detention time occurs. Instead, FMCSA research has focused on an overview of freight movement, including identifying inefficiencies in freight transportation and evaluating safety and productivity improvements. For example, FMCSA’s Motor Carrier Efficiency Study, a 2007 Annual Report to Congress, examined the application of wireless technology to improve the safety and efficiency of trucking operations in the United States. The analysis estimated that the motor carrier industry incurs financial losses in the tens of billions of dollars per year because of operating inefficiencies, and noted that “time loading and unloading” was the most costly inefficiency identified by motor carriers. While “time loading and unloading” is a key determination for whether detention time has occurred, the study does not specifically address instances of detention time or differentiate between expected time loading and unloading, and detention time. Also, FMCSA has conducted research on hours of service and driver fatigue with many studies completed, ongoing, or planned for the future. For example, FMCSA recently completed a study examining whether additional sleep would more effectively restore driver performance compared to the current 34-hour restart provision. In addition, FMCSA officials noted that the agency has several ongoing hours of service studies. Although FMCSA does not currently have data on detention time, the agency plans to conduct three studies addressing driver fatigue, driver compensation, and detention time. First, agency officials stated that a driver fatigue study is planned for July 2011. FMCSA officials stated that as part of this study, they plan to conduct an annual driver survey on driver fatigue to obtain an understanding of the impact of changes in the commercial driver workforce to ensure safety and well-being of its members. The results will be used to develop and evaluate rules, regulations, policies, and enforcement activities for the motor carrier industry. However, while FMCSA has developed a problem statement, it has yet to finalize the details on this study’s scope and methodology. Second, FMCSA plans to conduct a study examining the impact of driver compensation, such as pay per mile, on driver safety. Finally, FMCSA has requested funding for a study on detention time, which it plans to conduct in 2012. While FMCSA officials said they plan to survey drivers on the amount of time they wait to load or unload shipments, FMCSA has to date only developed a problem statement. The purpose of the study will be to better understand the nature of the problem of detention or waiting time in the industry. Agency officials stated the study will also identify any changes in current regulations that would reduce driver wait times. In addition, officials stated they will use the prior two studies to develop the detention time study’s scope or methodology. Therefore, it is not clear whether the detention time study will address, among other things, the extent to which detention time contributes to drivers violating hours of service requirements. In addition to FMCSA’s planned studies on detention time, collecting information on the factors that contribute to detention time through driver and vehicle inspections or other means could help FMCSA determine whether detention time is a significant factor in contributing to drivers violating hours of service requirements and, consequently, whether additional federal action by DOT or Congress might be warranted to mitigate detention time as a potential safety issue. For example, FMCSA could collect this type of information through level IV special inspections, which are typically one-time examinations based on an existing or potential problem and administered for data collection purposes—such as investigating defects in brakes or intermodal equipment—typically conducted in support of a study or to verify or refute a suspected trend. In 2009, FMCSA conducted over 16,500 level IV special roadside inspections in the United States. According to agency officials, level IV inspections are effectively level I standard inspections plus some additional questions for data collection, and the actual work and resources remain the same. These types of inspections can be administered in a designated period of time, such as a 3-day period when many inspections would be scheduled to occur. In addition, FMCSA could use a study-specific data collection form to acquire information on factors contributing to hours of service violations during inspections, similar to the methodology used in an unpublished FHWA study examining the violation of hours of service requirements in relation to the origin of the load. The study used an inspection form and a data collection form to acquire additional information outside of the standard inspection. Hours of service requirements are designed to ensure that truck drivers get the necessary rest to perform safe operations, to help continue the downward trend in commercial motor vehicle fatalities, and to maintain motor carrier operational efficiencies. All three goals further FMCSA’s primary mission to prevent fatalities and injuries involving commercial motor vehicles. Therefore, information on the factors that contribute to hours of service violations could help FMCSA in developing any future policy, rules, regulations, or programs to improve commercial vehicle safety. Any federal action to address issues associated with detention time beyond hours of service requirements would require careful consideration. Since there is no current federal regulation of detention time, any potential federal action would need to be based on a full understanding of the complexities of the industry. For example, a standard definition of detention time would need to be established. However, as we have shown, there are often disagreements between shippers and carriers regarding how much detention time occurred in a particular case, so finding a commonly agreed to definition in the industry could be challenging. It would also need to be decided which stakeholders any new federal action would target since there is a wide variety of stakeholders involved. Finally, the federal government would need to evaluate whether any unintended consequences may flow from a new federal action, and if so, how to avoid or mitigate those consequences. Detention time is a complex issue involving many stakeholders. While it is not uncommon for drivers to experience detention time, there are no data available that can provide any definitive information on how often it occurs, how long detention time lasts, or what types of carriers or facilities experience the most detention time. In fact, detention time can be difficult to measure as there are different interpretations of what constitutes detention time. Detention time can be caused not by one predominant factor, but instead by a wide variety of factors, primarily related to facility operations. Furthermore, some detention time likely results because shippers’ decisions affect the extent of detention time, but the costs of detention time are largely born by truckers. While detention time can have an economic impact on drivers and carrier companies, the current federal role in the industry focuses on safety—including hours of service requirements—rather than economic regulation. FMCSA’s plans to look at detention time in upcoming studies may shed further light on the contributing factors and extent of detention time, but the agency is still in the initial planning stages and has not determined the scope of these studies. Without information on the extent to which detention time occurs and the extent to which detention time contributes to hours of service violations, FMCSA may not have key information to help reduce these types of violations. To support the primary mission of FMCSA in improving the safety of commercial motor vehicles, we recommend the Secretary of DOT direct the Administrator of FMCSA to examine the extent to which detention time contributes to drivers violating hours of service requirements in its future studies on driver fatigue and detention time, and through data collected from its driver and vehicle inspections. We provided a draft of this report to DOT for review and comment. DOT officials provided technical comments which we incorporated into the report, as appropriate. As agreed with your office, unless you publicly announce the contents of this report earlier, we plan no further distribution until 30 days from the report date. The report also will be available at no charge on the GAO Web site at http://www.gao.gov. If you or your staff have any questions about this report, please contact me at (202) 512-2834 or flemings@gao.gov. Contact points for our Offices of Congressional Relations and Public Affairs may be found on the last page of this report. GAO staff who made major contributions to this report are listed in appendix V. To determine how regularly truck drivers experience detention time, the factors that contribute to detention time, and how detention time affects the interstate commercial motor carrier industry, we reviewed hours of service regulations, legislation related to the regulation of the trucking industry, and relevant Federal Motor Carrier Safety Administration (FMCSA) regulations; agency reports such as motor carrier efficiency studies; Federal Highway Administration (FHWA) freight facts and figures; and an Office of Motor Carriers study on trucking operations and hours of service. We also reviewed information about the trucking industry and driver safety overviews such as trucking logistics overviews, and background information on warehouse and distribution centers. To capture the various perspectives of the diverse trucking industry, we interviewed officials and representatives from FMCSA and FHWA, port authorities, carrier companies, trucking associations, manufacturing associations, warehouse facilities, and research firms. To conduct these interviews, we contacted officials and representatives across the country by phone, and we conducted site visits to Chicago, Illinois; Newark, New Jersey; and Port Arthur, Texas. In addition, we conducted structured interviews with truck drivers to gain a general understanding of (1) the frequency truck drivers experience detention time, (2) what truck drivers perceive to be the factors that contribute to detention time, and (3) how detention time affects them. After initially developing, reviewing, and modifying the interview questions, we conducted two pretests with truck drivers at truck stops in North Bend, Washington, and Baltimore, Maryland. The two pretests were conducted by GAO team members who approached respondents asking if they would like to answer a short questionnaire on detention time. The GAO team members asked the respondents the structured questions and noted any questions, comments, and lack of clarity to the questions on the part of the pretest respondents. The final changes made to the structured interview questions were made on the basis of observations from the pretests. A copy of the structured interview questions and results of the closed-ended questions are included in appendix II. The targeted population for the structured interviews was truck drivers. We conducted the interviews at four truck stops: Baytown, Texas; Ashland, Virginia; Walcott, Iowa; and North Bend, Washington. We chose these sites to obtain geographic dispersion and based on input from industry stakeholders. The GAO team members stationed themselves on- site where the highest volume of drivers was located, such as the front entrance. The GAO team members self-selected the respondents and therefore the results from this nongeneralizable sample cannot be used to make inferences about the population. Of the 549 truck drivers approached, 247 drivers declined to be interviewed, yielding a 55 percent response rate. Of the 302 truck drivers we interviewed, 230 identified themselves as only long-haul drivers, 21 drivers identified themselves as only short-haul drivers, 40 identified themselves as providing both long- and short-haul service, and 11 drivers did not provide a response. The structured interview of truck drivers contained a mixture of closed- ended and open-ended questions. In order to analyze drivers’ verbal responses to the open-ended questions, two analysts independently coded the responses and resolved any discrepancies in the categorization. To determine what federal actions, if any, could be taken to address the issues associated with detention time, we reviewed existing research and studies conducted by the Department of Transportation, such as FMCSA’s Motor Carrier Efficiency Study and FHWA’s report that provided an overview of the volume and value of freight flows in the United States. Further, we reviewed FMCSA’s plans for future research studies on detention time, driver fatigue, and driver compensation. In addition, we reviewed hours of service requirements; documentation on FMCSA’s enforcement of safety regulations, such as the types of driver and vehicle inspections; relevant laws and regulations related to the federal government’s role in the trucking industry, such as the Motor Carrier Act of 1935, the Motor Carrier Act of 1980, and the ICC Termination Act of 1995; and other relevant trucking industry requirements and rules, such as 49 C.F.R. part 395, and the electronic on-board recorder rule. Furthermore, we relied on FMCSA North American Free Trade Agreement Safety Statistics on out-of-service violations from roadside inspections for information on the number of hours of service violations. We did not independently verify those statistics since we reported them for contextual purposes, and they do not materially affect our findings. As such, we did not conduct a data reliability assessment of these data. Finally, we interviewed officials and representatives from FMCSA and FHWA, port authorities, carrier companies, trucking associations, manufacturing associations, warehouse facilities, and research firms to get their perspective on potential federal actions that could be taken to address detention time issues.

Summary: The interstate commercial motor carrier industry moves thousands of truckloads of goods every day, and any disruption in one truckload's delivery schedule can have a ripple effect on others. Some waiting time at shipping and receiving facilities--commonly referred to as detention time--is to be expected in this complex environment. However, excessive detention time could impact the ability of drivers to perform within federal hours of service safety regulations, which limit duty hours and are enforced by the Federal Motor Carrier Safety Administration (FMCSA). This report discusses: (1) How regularly do truck drivers experience detention time and what factors contribute to detention time? (2) How does detention time affect the commercial freight vehicle industry? (3) What federal actions, if any, could be taken to address detention time issues? GAO analyzed federal and industry studies and interviewed a nongeneralizable sample of truck drivers, as well as other industry stakeholders and FMCSA officials. While there are no industry-wide data on the occurrence of detention time, GAO interviews with over 300 truck drivers and a number of industry representatives and motor carrier officials indicate that detention time occurs with some regularity and for a variety of reasons. About 59 percent of interviewed drivers reported experiencing detention time in the past 2 weeks and over two-thirds reported experiencing detention time within the last month. Drivers cited several factors that contribute to detention time. About 43 percent of drivers identified limitations in facilities, such as the lack of sufficient loading and unloading equipment or staff. These limitations can occur when facilities overschedule appointments, creating a backlog of vehicles. Another factor cited by about 39 percent of drivers was the product not being ready for shipment. Other factors include poor service provided by facility staff, facility scheduling practices that may encourage drivers to line up hours before the facility opens, and factors not under the control of the facility, such as drivers filing paperwork incorrectly. Some facilities are taking steps to address these factors, such as using appointment times. Detention time can result in reduced driving time and lost revenue for drivers and carriers. For those drivers that reported previously experiencing detention time, about 80 percent reported that detention time impacts their ability to meet federal hours of service safety requirements--a maximum of 14 hours on duty each day, including up to 11 hours of driving--by reducing their available driving time. About 65 percent of drivers reported lost revenue as a result of detention time from either missing an opportunity to secure another load or paying late fees to the shipper. Some practices can mitigate these economic impacts, such as charging detention time fees and developing relationships with facilities so drivers become familiar with a facility's process. According to industry representatives, carrier companies are better positioned than independent owner operators to use such practices and are better able to handle logistical challenges that may result from detention time. While FMCSA collects data from drivers during roadside inspections, which provide information on the number of hours of service violations, the agency currently does not collect--nor is it required to collect--information to assess the extent to which detention time contributes to these violations. Agency officials stated that FMCSA does not identify the factors that contribute to hours of service violations, and detention time could be just one of many factors. To date, FMCSA research has focused on an overview of freight movement, but not the extent to which detention time occurs or how it may impact hours of service violations. FMCSA plans to conduct a 2012 study to better understand the extent to which detention time occurs. Obtaining a clearer industry-wide picture about how detention time contributes to hours of service violations could help FMCSA determine whether additional federal action might be warranted. However, any additional federal actions to address issues associated with detention time beyond hours of service would require careful consideration to determine if any unintended consequences may flow from federal action to regulate detention time. GAO recommends that FMCSA examine the extent to which detention time contributes to hours of service violations in its future studies on driver fatigue and detention time. We provided a draft of this report to DOT for review. DOT officials provided technical comments, which we incorporated into the report, as appropriate.
