What does 14-hour dot mean?

14-Hour Limit 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.



The "14-hour rule" is a mandatory safety regulation set by the Department of Transportation (DOT) and the FMCSA to prevent truck driver fatigue. It states that a commercial driver may not drive beyond the 14th consecutive hour after coming on duty following 10 consecutive hours off duty. Crucially, the 14-hour "clock" does not stop for breaks, meals, or fueling; once a driver starts their workday, the clock runs relentlessly. Within that 14-hour window, a driver is only permitted to spend a maximum of 11 hours actually driving. In 2026, these rules are strictly enforced via Electronic Logging Devices (ELDs). If a driver hits the 14-hour mark, they must stop all work-related activities and take a full 10-hour rest period before they are legally allowed to get behind the wheel again.
