Split Sleeper Berth Calculator
Enter your two breaks and the work around them. You get a yes/no on the 8/2 and 7/3 pairing, your remaining driving and window hours after the recalculation, and the whole day laid out on one line.

Quarter hours are fine. The 7-hour stretch must be logged as sleeper-berth time; the other break can be off duty or in the berth.

Questions drivers actually ask
Does the 2-hour break have to be in the sleeper?
No. The short break can be off duty, in the berth, or a mix. Only the long break needs 7 consecutive hours in the berth.
Why didn't my 14 reset after the split?
Because a split recalculate, it doesn't reset. The new window starts at the end of your first break, the two breaks don't count against it, but everything you worked between them does — and your 11 driving hours carry over. A split never adds drive time.
Can I run a 6/4 or 5/5?
Not under the current rule — one period needs 7 consecutive berth hours. FMCSA is piloting 6/4 and 5/5 with enrolled drivers only.
Does the split touch my 70?
No. Split sleeper changes your day, not your week.
