Hours of service calculator
How much driving you have left today under the US federal rules for property-carrying drivers: the 11-hour limit, the 14-hour window and the 30-minute break.
This covers the basic federal property-carrying rules only. It does not handle the sleeper berth split, the adverse driving conditions extension, short-haul exceptions, the 60/70-hour limit, passenger carriers, state intrastate rules or Canada. Your ELD and the official FMCSA rules are what count.
The three clocks, in plain words
The 11-hour limit. After 10 hours in a row off duty, you can drive up to 11 hours in total.
The 14-hour window. The clock starts when you come on duty and runs straight through. Breaks, waiting at a shipper and fueling don't stop it. Once 14 hours have passed, you can't drive again until you've had another 10 hours off. You can still do other work, like paperwork or fueling.
The 30-minute break. After 8 hours of driving in total without a break of at least 30 minutes, you need one before you drive again. Off duty, sleeper berth or on-duty time that isn't driving all count toward it.
