How does the 8/2 split rule work?

The split sleeper berth rule allows drivers to split the required 10 consecutive hours of off-duty time into two shifts in order to extend the shift.

For example, a driver can adjust their schedule for longer hauls by “dropping in” a break to comply with any Hours of Service drive-time limitations.  

According to the new HOS rules, the 8/2 split states that a driver may drive for up to six hours, and then take a two-hour off-duty break before driving another five hours. 

An eight-hour off-duty period would commence at that time, and when combined with the two-hour off-duty period, meets the FMCSA requirement of 10 hours equivalent off duty.
