Split sleeper-berth rule

Glossary / Hours of service / Split sleeper-berth rule

The split sleeper-berth rule is a regulation in the trucking industry that governs the amount of time a driver must spend resting or sleeping during a trip. This rule allows drivers to split their required 10-hour off-duty period into two segments, with one segment being at least 8 hours in a sleeper berth and the other segment being at least 2 hours either in the sleeper berth, off-duty, or a combination of both.

The purpose of the split sleeper-berth rule is to provide truck drivers with a more flexible schedule that allows them to rest or sleep when they need to and avoid driver fatigue.
Driver fatigue is a leading cause of accidents in the trucking industry, so this regulation is crucial for ensuring the safety of both the driver and other motorists.

Under the split sleeper-berth rule, drivers must still comply with the 14-hour driving window and 11-hour driving limit. This means that the driver must not drive beyond 14 hours after starting their duty period and must not drive beyond 11 hours after taking a break of at least 10 consecutive hours.

It is important to note that the split sleeper-berth rule is not mandatory. Drivers can still choose to take the full 10 hours off-duty in one period. However, for those who choose to use the split sleeper-berth rule, it can help them to
better manage their rest and driving schedule, which can lead to a more manageable and safer driving experience.
