Split Sleeper Calc

Two rest periods go into Split Sleeper Calc to check whether they pair under FMCSA sleeper berth rules, including common 7/3 and 8/2 splits. The tool requires entering the two rest periods exactly as logged with an explicit fixed UTC offset, so local time is never guessed. Every calculation runs on whole minutes, meaning a rest period of 6 hours and 59 minutes never rounds up into a qualifying 7-hour leg.

7/3 and 8/2 splits, resets and 2026 guidance branches

For property-carrying drivers, the ordinary sleeper berth provision splits the required 10 hours of rest into two distinct segments: one period of at least 2 hours off duty or in the sleeper berth, and another period of at least 7 consecutive hours in the sleeper berth. Together, the two periods must total at least 10 hours. FMCSA states that when these two qualifying periods are used together, neither counts against the maximum 14-hour driving window. Surrounding limits include up to 11 hours of driving after 10 consecutive hours off duty, and no driving past the 14-hour point after coming on duty.

Guidance effective July 1, 2026, allows a qualifying 10-consecutive-hour rest that includes at least 7 consecutive sleeper hours to either restart the 11-hour and 14-hour limits or pair with a later qualifying period of at least 2 hours. The calculator keeps both readings as separate branches. The 6/4 and 5/5 alternatives are limited 2026 Flexible Sleeper Berth pilot options for approved test participants, so the engine does not offer them and will not report a 6-and-4 or 5-and-5 pattern as qualifying.
