Truck driving regulations typically limit the hours a truck driver can drive within a specified time. These regulations prevent driver fatigue and promote road safety. FMCSA’s regulations regarding truck driving include: Hours of Service (HOS). FMCSA establishes the hours of service regulations for truck drivers operating commercial motor vehicles (CMVs) in interstate commerce. The key provisions for property-carrying CMV drivers are: 14-Hour Duty Limit: A driver cannot drive beyond the 14th consecutive hour after coming on duty, following 10 consecutive hours off duty. 11-Hour Driving Limit: A driver cannot drive for more than 11 hours after 10 consecutive hours off duty. 30-Minute Rest Break: A driver must take a minimum 30-minute break if more than eight hours have passed since their last off-duty or sleeper-berth period. 60/70-Hour Duty Limit: A driver cannot drive after 60/70 hours on duty in seven/eight consecutive days. The driver must take a minimum of 34 consecutive hours off duty before starting a new seven/eight-day period. Sleeper-Berth Provision: Drivers using a sleeper-berth to accumulate their required off-duty time must spend at least eight hours in the sleeper berth, plus a separate two hours either in the sleeper berth, off duty, or a combination of both. Truck drivers and trucking companies must comply with these regulations to ensure driver safety and promote road safety. Non-compliance with these regulations can result in penalties, fines, and other legal consequences. In addition to any administrative consequences, you can hold a truck driver or trucking company liable if a fatigued truck driver caused an accident that seriously injured you or a loved one.
