What is the 70-hour Rule? The 70-hour in 8 days rule (or 60 in 7) is the total time spent Driving and ON-Duty, and cannot exceed 70 hours in any 8-day period (or 60 hours in any 7-day period). In other words, drivers have a limited number of hours they can be ON-Duty per cycle (week).

The 70-hour rule is a cornerstone of the Department of Transportation's (DOT) "Hours of Service" (HOS) regulations for commercial truck drivers in 2026. Specifically, it is the 70-hour/8-day rule, which prohibits a driver from driving after they have been "on duty" for 70 hours in any period of 8 consecutive days. This is a "rolling" window; as each day passes, the hours worked on the 9th day back drop off the tally, "regaining" those hours for the driver. To "reset" this clock completely, a driver must take a 34-hour restart, which means spending 34 consecutive hours off-duty. In 2026, this is strictly monitored via Electronic Logging Devices (ELDs) that are hardwired into the truck's engine. If a driver hits 70 hours on day 7, they cannot legally drive again until enough hours "drop off" or they complete the 34-hour reset. This rule is designed to combat driver fatigue and improve road safety, ensuring that long-haul truckers are not pushed beyond their physical limits by demanding shipping schedules or high-pressure logistics companies.
