The 8/2 split rule is part of the Sleeper Berth Provision outlined in the Federal Motor Carrier Safety Administration (FMCSA) Hours of Service (HOS) regulations. This rule permits commercial drivers to split their mandatory 10-hour off-duty rest period into two segments, allowing for greater flexibility while adhering to safety and compliance standards.

Under The 8/2 Split Rule:

  1. 8-hour Segment: Drivers must spend at least 8 consecutive hours in the sleeper berth. This time does not count toward the driver’s 14-hour on-duty window.
  2. 2-hour Segment: Drivers must take an additional 2 consecutive hours off-duty or in the sleeper berth. This time may count toward the 14-hour duty clock.

The key benefit of the 8/2 split rule is that it pauses the driver’s 14-hour duty clock during the 8-hour sleeper berth period. This flexibility allows drivers to adjust their schedules for unexpected delays or optimize driving times during low-traffic periods.

For example, a driver may drive for 6 hours, take an 8-hour sleeper berth break, drive for another 4 hours, and then take a 2-hour off-duty break. These two segments satisfy the 10-hour rest requirement without disrupting compliance.

Manually tracking split breaks can be challenging, but TruckX’s Electronic Logging Device (ELD) simplifies the process. By automatically recording sleeper berth and off-duty periods, TruckX ensures drivers remain FMCSA-compliant, avoid HOS violations, and prioritize safety on the road.
