Hours of service - Maryland

Maryland has adopted Part 395 of the Federal Motor Carrier Safety Regulations (FMCSRs), as amended.

Part 395 applies to vehicles with a gross vehicle weight rating or gross combination weight rating of 10,001 or more pounds as well as to anyone transporting hazardous materials requiring placarding.

Exception: Hours of duty limits do not apply to intrastate drivers operating only within a 150-mile air radius of the driver’s normal work reporting location if the driver returns to the work reporting location and is released within 16 consecutive hours. Of those 16 consecutive hours no more than 12 hours shall be dedicated to driving. The driver must then be given at least 8 consecutive hours off duty. This exception does not apply to drivers transporting hazardous materials requiring placarding.

Maximum on-duty limits under the exception are 70 hours in 7 consecutive days and, if operating vehicles every day, 80 hours in 8 consecutive days.

A record of duty status is not required unless the driver is on duty for more than 12 hours. In that case, the driver must maintain a record of duty status that accounts for all driving time during the first 12 hours and accounts for all time, in conformance with federal regulations, after that.
