Shippers plan in transit days. Drivers work in hours, and those hours are capped by federal rules. When a load that looked like an easy two-day run turns into three, or a truck that arrived on time cannot make its next appointment, the cause is very often the driver’s clock. You do not need to be a compliance expert to ship freight, but understanding the basics of hours of service will make your schedules more realistic and your facility easier to serve.
This is a general overview of the rules for property-carrying drivers in the United States. The regulations contain exceptions and details that are not covered here. The Federal Motor Carrier Safety Administration publishes the official version at fmcsa.dot.gov.
The core limits
Four numbers explain most of what shippers run into.
11 hours of driving
A driver may drive a maximum of 11 hours after 10 consecutive hours off duty. Once those 11 hours are used, the driver must take another 10 hours off before driving again.
The 14-hour window
This is the one that affects shippers most. A driver may not drive beyond the 14th consecutive hour after coming on duty. The window starts when the driver begins any work, and in general it keeps running through fueling, inspections, traffic and time spent waiting at a dock. Driving time and the 14-hour window are two separate clocks, and whichever runs out first stops the truck.
The 30-minute break
A driver must take a break of at least 30 consecutive minutes after 8 cumulative hours of driving without an interruption of that length.
The 60/70-hour limit
A driver may not drive after being on duty 60 hours in 7 consecutive days or 70 hours in 8 consecutive days, depending on how the carrier operates. A driver can reset this weekly total by taking at least 34 consecutive hours off duty.
There is also a sleeper berth provision that lets drivers split their required off-duty time into two periods under specific conditions. It gives some flexibility, but it is not something a shipper should build a schedule around.
Why the 14-hour window is a shipper’s problem
Consider a driver who starts the day at 6:00 a.m. The window closes at 8:00 p.m. no matter what. If that driver arrives at your dock at 8:00 a.m. for a pickup and is not loaded until noon, four hours of the window are gone and none of them moved the freight. The driver now has eight hours of window left and cannot use all 11 hours of driving.
That lost time shows up as a later delivery, a missed appointment at the other end, or a carrier that declines your next load. The link between dock delays and service is covered in depth in why drivers wait at the dock and how to reduce it.
What this means for transit times
A rough planning rule many people in the industry use is that a solo driver covers something in the range of 450 to 550 miles in a day once fueling, breaks, traffic and stops are counted. The number varies with terrain, congestion and how much time is spent at docks. It is not a regulation, just a planning habit, and a carrier’s own estimate for your lane is always better.
The important point is that transit is not simply distance divided by speed. A 1,000-mile trip is a two-day move for a solo driver under good conditions. Add a late-afternoon pickup and a morning-only receiver and it can become three. When freight truly has to move faster, a two-driver team can keep the truck rolling while one driver rests, as explained in team drivers vs. solo drivers. Other premium options are covered in expedited freight explained.
Electronic logs changed the conversation
Most drivers subject to these rules record their hours with an electronic logging device connected to the truck. The device records driving time automatically. In practice this means there is very little room to “make it work” when a schedule is too tight. If the clock says the driver is out of hours, the truck stops.
This is worth remembering when a driver says they cannot wait any longer or cannot make a delivery tonight. It is rarely a negotiating position. It is usually the log.
How shippers can help
Load and unload on time
Nothing a shipper does has more effect on a driver’s available hours. Stage freight before the truck arrives. Have paperwork ready. If you are running behind, tell the carrier early so they can plan.
Offer realistic appointment windows
A pickup at 3:00 p.m. followed by a delivery at 7:00 a.m. the next morning 600 miles away is not legal for one driver, whatever the map says. Ask the carrier what is achievable before setting appointments, and build in some slack.
Be flexible on receiving hours
Narrow receiving windows force drivers to arrive early and wait or arrive late and miss. Facilities that can receive across a wider part of the day, or that allow drop trailers, are much easier to cover. See drop and hook trucking explained for how that works.
Allow safe parking when you can
A driver who runs out of hours at your facility needs somewhere to stop. Truck parking is scarce in many areas. Shippers that let drivers park on site, even for a required break, earn real goodwill.
Ask before you tender
For time-sensitive freight, ask the carrier directly: can a solo driver legally make this schedule? A good carrier or broker will give you a straight answer and alternatives.
What not to do
Do not pressure a driver or dispatcher to run a schedule that cannot be done within the rules. Federal regulations prohibit coercing drivers to violate safety rules, and that prohibition reaches shippers, receivers and intermediaries, not only motor carriers. Beyond the legal exposure, a schedule that only works if someone breaks the rules is a schedule that will eventually fail.
Common questions
Does waiting at my dock count against the driver?
In most situations, yes. Time spent waiting to be loaded or unloaded generally counts against the 14-hour window, which is why long waits are so costly.
Can the driver just take a break at my dock and extend the day?
An ordinary short break does not extend the 14-hour window. Certain sleeper berth arrangements can pause it, but those depend on the equipment and the driver’s situation and should not be assumed.
Do these rules apply to local trucks?
Some short-haul operations work under modified requirements. Your carrier will know which rules apply to its drivers.
The takeaway
Hours-of-service rules exist to keep tired drivers off the road. For shippers, they turn every hour at the dock into an hour that cannot be driven later. Plan transit with the driver’s clock in mind, keep your dock moving, and ask carriers what is realistic. Your freight will arrive more predictably, and carriers will want to come back.
