How do split sleeper berth rules work under HOS regulations?

The split sleeper berth provision under the Hours of Service (HOS) regulations provides drivers with flexibility in how they manage their mandatory rest periods. This rule allows drivers to divide their required 10-hour off-duty period into two distinct segments under specific conditions:

• a. Standard HOS Rest Requirements: Generally, drivers must take a continuous 10-hour off-duty break to reset their driving hours. The split sleeper berth rule provides an alternative method to meet this requirement.

• b. Split Options: Drivers can split their rest period into two segments: Option 1: 8 hours in the sleeper berth and 2 hours off-duty (in or out of the sleeper). Option 2: 7 hours in the sleeper berth and 3 hours off-duty (in or out of the sleeper).

• c. Key Conditions: Both rest periods must add up to at least 10 hours. The longer sleeper berth period (7 or 8 hours) does not count toward the 14-hour duty clock, effectively pausing it.

• d. Benefits: This provision helps drivers manage their schedules better, allowing flexibility during delays or multi-stop trips. It reduces pressure to find a safe parking spot when nearing HOS limits, as drivers can take a shorter rest period and resume driving later.

• e. Challenges: Properly logging and calculating compliance can be complicated, especially for drivers unfamiliar with the rules. Many rely on Electronic Logging Devices (ELDs) to ensure accuracy.
