8/2 Split Break Calculator
Check whether your split qualifies as an 8/2-style sleeper berth split and estimate how much 11-hour driving time and 14-hour duty-window time remains after the second qualifying break.
Enter split break details
One break must be at least 8 hours in the sleeper berth, the other must be at least 2 hours off duty or in the sleeper, and the total must be at least 10 hours.
Logic Summary:
Split = 1 Sleeper (8h+) + 1 Break (2h+), Total 10h+.
Remain Drive = 11 − Drive used between paired breaks.
Remain Window = 14 − (Drive + On-Duty used between paired breaks).
Split = 1 Sleeper (8h+) + 1 Break (2h+), Total 10h+.
Remain Drive = 11 − Drive used between paired breaks.
Remain Window = 14 − (Drive + On-Duty used between paired breaks).
