DOT Proposal to Add Split Sleeper Pilot to HoS

The U.S. DOT announced a plan to introduce a pilot program to study the feasibility of allowing truck drivers to split their off-duty sleeper berth time into segments, rather than having to take 10 straight hours off duty or use the limited 8-2 split. The agency also announced that 240 drivers have been selected to participate in the program.

According to Heavy Duty Trucking, FMCSA said it plans to file its research plan with the White House’s Office of Management and Budget, who must approve the study before the agency proceeds. The move is the latest step toward potential revision of hours of service regs to add long-wanted flexibility for truck operators.

The Federal Motor Carrier Safety Administration in June issued a proposal for the split sleeper study. The agency’s plan is to study the 240 drivers for three months. Participating drivers will be able to split their 10-hour off-duty period into segments, such as 5-5, 6-4 or 7-3. Otherwise, drivers will operate as they normally would.

Researchers will seek to determine whether such splits adversely affect operator fatigue levels or crash instances. The agency has partnered with Virginia Tech’s Transportation Institute and Washington State University to conduct the study.

The study seeks to gather data from ELDs, monitoring systems like video recorders, roadside inspections, wrist actigraphy (studying total sleep time and wakefulness), psychomotor vigilance tests taken in cab, subjective sleepiness ratings as noted by drivers and sleep logs. Researchers will then study the data and make conclusions regarding the positive or negative outcomes of drivers using split sleeper berth options.

The agency is accepting public comments for 30 days on its announcement to send its research request to the OMB. Public comments can be made here, at the regulations.gov rulemakings portal.

Canadian federal regulations last amended in 2005 allow the use of the split sleeper berth provision, not currently allowed in the US. Drivers in Canada can opt to use the split sleeper provision in 3-7, 6-4, 5-5 hour timeframes and vice versa.  For details associated with split sleeper berth in Canada please click here
