Many commercial vehicles are built with an area for the driver to rest, commonly referred to as a ‘sleeper cab’ or ‘sleeper berth.’ If a truck has a sleeper available, the driver has the option to split up their rest period according to the ‘Sleeper Berth Provision’ provided by the FMCSA.  Under this rule, drivers may split their 10-hour off-duty period as long as one off-duty period involves at least 7 consecutive hours spent in the sleeper berth and the other is at least 2 hours long, spent either in or out of the sleeper. The two rest periods must add up to 10 hours in order to comply with FMCSA regulations. Many truckers believe they can officially log a sleeper berth rest period even if their truck does not have a sleeping area. If a driver chooses to do so, a law enforcement officer (LEO) would be authorized to issue them a logbook violation ticket. The best policy for drivers traveling without a sleeper berth is to record their rest time as ‘off-duty.’
