Driving in Canada? Canadian rules set different daily and cycle limits, so this calculator covers only the US legs of a trip. Read Canada's hours of service rules.

Frequently Asked Questions

What is the 11-hour driving rule?

The 11-hour driving rule means a driver may drive a maximum of 11 hours after 10 consecutive hours off duty. Once 11 hours of driving time have been used, the driver must take another 10 consecutive hours off before driving again.

What is the 14-hour window?

The 14-hour window means a driver cannot drive once 14 consecutive hours have passed since coming on duty following 10 consecutive hours off duty. Off-duty breaks do not extend it, though exceptions such as a qualifying split sleeper berth period or adverse driving conditions can. This calculator does not model those exceptions.

What is the 30-minute break rule?

The 30-minute break rule requires drivers to take a 30-minute break after 8 cumulative hours of driving time. The break can be satisfied by any non-driving period of 30 consecutive minutes, including on-duty not driving, sleeper berth, or off-duty time.
