How many consecutive hours do you need off to open a new 14 hour work window?
May not drive beyond the 14th consecutive hour after coming on duty, following 10 consecutive hours off duty. Off-duty time does not extend the 14-hour period.
What is the 11th hour rule?
Safe Driving Requirements
Most people are able to drive safely for up to 11 hours per 24-hour period before they become extremely fatigued — which can lead to poor decisions and dangerous road conditions. The 11-hour rule is intended to keep everyone safe on the road.
When did the 14 hour rule start?
Late 2007: FMCSA published an Interim Final Rule, effective Dec. 27, to allow up to 11 hours of driving time within a 14-hour, non-extendable window following 10 consecutive hours off duty. It also allowed a restart of the weekly on-duty time limits after the driver had at least 34 consecutive hours off duty.
