The DOT 10-hour rule requires property-carrying commercial drivers to spend at least 10 consecutive hours off duty before getting back behind the wheel. It comes from the Federal Motor Carrier Safety Administration’s hours-of-service regulations at 49 CFR 395.3, and completing that full rest is what resets the daily driving and on-duty clocks for the next shift.1eCFR. 49 CFR 395.3 – Maximum Driving Time for Property-Carrying Vehicles
What “10 Consecutive Hours Off Duty” Actually Means
Off duty means completely relieved of all work responsibilities, including anything tied to the truck, the cargo, or the carrier’s business. Answering a dispatch call, supervising loading, or handling a minor administrative task during your rest breaks the off-duty status, and the 10-hour clock has not started.
The word “consecutive” is doing real work in the rule. Six hours off, a phone call for the carrier, then four more hours off does not add up to a valid reset. The entire block has to be unbroken. That structure exists so carriers can’t chip away at a driver’s recovery with small work requests spread across a rest period.
What the 10-Hour Reset Restores
Two daily limits are tied directly to the 10-hour rest, and neither is available again until the rest is complete.
The 11-Hour Driving Limit
After a full 10 hours off, a property-carrying driver may drive up to 11 hours total during the next shift.1eCFR. 49 CFR 395.3 – Maximum Driving Time for Property-Carrying Vehicles This clock only runs when the vehicle is actually moving. Three hours spent on non-driving duties don’t eat into it. Once those 11 hours are used, driving has to stop until another 10 consecutive hours off duty (or a qualifying sleeper berth split) restores the limit.
The 14-Hour On-Duty Window
The moment you come on duty after your 10-hour rest, a 14-hour window starts counting down.1eCFR. 49 CFR 395.3 – Maximum Driving Time for Property-Carrying Vehicles You cannot drive after it closes, regardless of how much of the 11 driving hours you have left. Fueling, inspections, dock waits, and meals all pass inside that window. It runs continuously and does not pause for non-driving work. The only way to restart it is another 10 hours off duty or a qualifying split.
One related requirement sits inside the driving day rather than the rest period: after 8 cumulative hours of driving time, a driver must take at least a 30-minute break before driving again.2Federal Motor Carrier Safety Administration. Summary of Hours of Service Regulations Any non-driving time counts, whether logged as off-duty, sleeper berth, or on-duty not driving.
Splitting the 10 Hours in the Sleeper Berth
The 10 hours don’t have to happen in a single block. Under the split sleeper berth provision, you can divide the rest into two periods if one is at least 7 consecutive hours in the sleeper berth and the other is at least 2 hours in the sleeper berth or off duty, and the two together add up to at least 10 hours.3eCFR. 49 CFR 395.1 – Scope of Rules in This Part
What makes the split useful is how it interacts with the 14-hour window. Neither qualifying rest period counts against that window when the split is used properly.2Federal Motor Carrier Safety Administration. Summary of Hours of Service Regulations Available driving time is recalculated from what you had remaining when the first qualifying rest began. Common patterns are 7 and 3 or 8 and 2, in either order. The flexibility is the point: freight schedules rarely line up with rigid 10-hour blocks, and the split lets drivers work around loading delays or appointment windows without burning through the day sitting still.
Adverse Driving Conditions
Weather, road closures, and traffic conditions that weren’t known or reasonably foreseeable at dispatch can qualify for an exception. A driver in that situation may extend driving by up to 2 additional hours beyond both the 11-hour driving limit and the 14-hour window to reach a safe stopping point.3eCFR. 49 CFR 395.1 – Scope of Rules in This Part A dispatcher who knew about a storm before sending the driver out cannot claim the exception after the fact.
The 10-hour off-duty requirement itself is not extended or shortened by this exception. Even after a 13-hour driving day under adverse conditions, the next shift still requires a full 10 hours off.
Moving the Truck During Your 10 Hours
Drivers often ask whether the truck can be moved at all during off-duty time without breaking the rest period. It can, under FMCSA’s personal conveyance guidance, but only when you are genuinely relieved of all work responsibilities.4Federal Motor Carrier Safety Administration. Personal Conveyance Driving from a truck stop to a nearby restaurant, commuting between a terminal and home, or moving to the nearest safe place to rest after unloading can all be logged as off-duty personal conveyance. The vehicle can be loaded, as long as the movement isn’t for the carrier’s commercial benefit.
What doesn’t qualify: repositioning closer to the next delivery, bobtailing to pick up another load, or driving to a maintenance facility. Those are business purposes, and logging them as off-duty is a falsification issue. Carriers can also impose stricter limits than FMCSA does, including banning personal conveyance outright or setting distance caps.
Passenger-Carrying Drivers Have Different Numbers
The 10-hour rule applies to property-carrying commercial drivers. If you drive a bus, motorcoach, or other passenger-carrying commercial vehicle, the required off-duty period is 8 consecutive hours, not 10. After that rest, passenger-carrying drivers may drive up to 10 hours and be on duty for up to 15 hours.5eCFR. 49 CFR 395.5 – Maximum Driving Time for Passenger-Carrying Vehicles The 15-hour duty limit is non-consecutive: off-duty and sleeper berth time doesn’t count against it, unlike the property-carrying 14-hour window that runs straight through.
What Happens If You Break the Rule
Roadside inspectors check compliance by reviewing ELD or paper log data. A driver caught operating without a completed 10-hour rest is placed out of service under 49 CFR 395.13 and cannot operate any commercial vehicle until the required off-duty time is finished.6eCFR. 49 CFR 395.13 – Drivers Declared Out of Service The truck stays wherever it stopped for the duration, and if the location isn’t suitable, towing and storage costs can pile on.
Civil penalties are adjusted annually for inflation. Current maximums include:
- Non-recordkeeping HOS violation by a driver: up to $4,812 per violation.
- Non-recordkeeping HOS violation by a carrier: up to $19,246 per violation.
- Recordkeeping violations: up to $1,584 per day, capped at $15,846.
- Driver violating an out-of-service order: up to $2,364 per violation.
- Carrier permitting a driver to violate an out-of-service order: up to $23,647 per violation.
Driving more than 3 hours beyond the 11-hour driving limit or the 10-hour off-duty requirement is classified as an egregious violation, and FMCSA treats that severity as justifying the maximum fine allowed by law.7eCFR. Appendix B to Part 386 – Penalty Schedule Repeated violations also pull down a carrier’s safety rating, which affects insurance, contracts, and operating authority.
