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 after being on duty for 14 hours following 10 consecutive hours off duty. This is a hard window that cannot be extended with breaks — once 14 hours have passed since coming on duty, driving must stop.

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.
