# ACTION:

Notice of proposed rulemaking (NPRM); extension of comment period. 

# SUMMARY:

The FMCSA is extending this rulemaking's comment period until October 30, 2000. This is in response to numerous petitions received by the FMCSA from motor carriers, drivers and trucking associations, and several members of Congress requesting an extension of the comment period closing date. The petitioners based their requests on the time required to review the vast body of research, assess the impact of the proposed rules, and provide meaningful comments. 

                        The FMCSA is also placing in the docket the pre-publication final report on “Effects of Sleep Schedules on Commercial Motor Vehicle Driver Performance,” prepared by the Division                               ( print page 37957)                            of Neuropsychiatry, Walter Reed Army Institute of Research.

# SUPPLEMENTARY INFORMATION:

On May 2, 2000 (65 FR 25540), the FMCSA published an NPRM proposing to revise its hours-of-service (HOS) regulations to require motor carriers to provide drivers with better opportunities to obtain sleep, and thereby reduce the risk of drivers operating commercial motor vehicles (CMV) while drowsy, tired, or fatigued to reduce crashes involving these drivers. The FMCSA explained that this action is necessary because we estimate that 755 fatalities and 19,705 injuries occur each year on the nation's roads because of drowsy, tired, or fatigued CMV drivers. The proposed regulations would: 

1. Revert to a 24-hour daily cycle, and a 7-day weekly cycle. 

2. Adjust the work-rest requirements for various types of operations. 

3. Emphasize rest. Require, for long-haul and regional drivers, a period of 10 consecutive hours off duty within each 24-hour cycle, and two hours of additional time off in each 14-hour work period within each 24-hour cycle. 

4. Require weekends, or their functional equivalent, to include at a minimum a rest period that includes two consecutive periods from 11 p.m. to 7 a.m. 

5. Require the use of electronic on-board recorders in CMVs used by drivers in long-haul and regional operations. 

The FMCSA has received petitions from the American Trucking Associations, Commercial Vehicle Safety Alliance, Distribution and LTL Carriers Association, National Private Truck Council and numerous motor carriers, drivers, other industry associations, and members of Congress requesting that the comment period to be extended. The petitioners voiced concerns that the lengthy proposed rule was extremely complex and that 90 days was insufficient time to review the research, assess the impact of the proposed rules on CMV operations, and provide meaningful comments. We agree that more time for in-depth analysis of the NPRM, including the numerous studies involving fatigue, driver physiology, crash data, and operating characteristics of the various CMV operations, by the affected parties, would be beneficial to the FMCSA in this rulemaking. For the reasons above, the FMCSA finds good cause to extend this NPRM comment period closing date for 90 days. 

The FMCSA is also placing in the docket the pre-publication final report on “Effects of Sleep Schedules on Commercial Motor Vehicle Driver Performance,” prepared by the Division of Neuropsychiatry, Walter Reed Army Institute of Research.
