Notes & exceptions

Adverse driving conditions: 11/14 limits may extend by up to 2 hours.
Sleeper-berth split (8/2 or 7/3) can pause the 14-hr window — this calculator does not model splits.
Short-haul exception (within 150 air-miles, return to home base in 14 hrs) skips the 30-min break and 14-hr ELD log.
34-hour off-duty restart resets the 60/7 or 70/8 clock.
This is an unofficial estimator — not a substitute for an ELD or your safety department.
