When a driver will run out of hours before delivery, the driver must stop at a safe, legal place and take the required off-duty time, or the load has to change hands. The practical options are: park and reschedule the appointment, send a relay driver, use a team on the next attempt, drop the trailer where the receiver allows it, or move the freight onto another truck at a dock the driver can legally reach. Pushing the driver past the limit is not one of the options.
Running out of hours is a different problem from detention. Detention is about who pays for the time a truck waits. Hours of service (HOS) is about whether the driver can legally keep driving at all. A long wait at a shipper often causes both, because federal rules count time waiting at a shipper or facility to be dispatched as on-duty time unless the carrier has relieved the driver from duty.[1] This guide covers the HOS side and the options for the freight. For the money side, see who pays when a truck driver waits.

Key takeaways
- For property-carrying drivers, the limits are 11 hours of driving inside a 14-hour window, a 30-minute break after 8 hours of driving, 10 hours off before the next shift, and a 60 or 70 hour weekly cap.
- Waiting at a shipper usually counts as on-duty time, so a long load or unload eats the 14-hour window even though the truck is not moving.
- The adverse driving conditions exception is for conditions that could not reasonably be known before dispatch, not for routine congestion.
- When hours run out, the legal answers are to stop and rest, or to change who drives or which truck carries the freight.
The HOS Rules That Decide the Problem
The hours-of-service limits for drivers of property-carrying commercial vehicles are in 49 CFR 395.3. These are the ones that usually decide whether a load gets delivered today.
| Rule | What the regulation says | What it means for the load |
|---|---|---|
| 10 hours off | A driver may not drive without first taking 10 consecutive hours off duty.[2] | Once the driver is out of hours, the next shift starts only after a full 10-hour break. |
| 14-hour window | A driver may not drive after 14 consecutive hours after coming on duty.[2] | The window keeps running while the driver waits at a dock. Hours spent loading count against it. |
| 11-hour driving limit | A driver may drive a total of 11 hours during that 14-hour period.[2] | A driver with driving time left can still be stopped by the 14-hour window. |
| 30-minute break | Driving is not permitted if more than 8 hours of driving time have passed without at least a 30-minute interruption, which can be off duty, sleeper berth or on duty not driving time.[2] | A long wait at a dock can satisfy the break, but it still uses the 14-hour window. |
| 60/70-hour limit | No driving after 60 hours on duty in 7 consecutive days, or 70 hours in 8 consecutive days if the carrier operates every day of the week. A 7 or 8 day period may end with 34 or more consecutive hours off duty.[2] | A driver can have daily hours left but no weekly hours. Ask about both. |
The definition of on-duty time is what turns a slow dock into an HOS problem. It covers all time from when a driver begins work or must be ready to work until the driver is relieved of all responsibility, including time at a shipper’s facility or on public property waiting to be dispatched, unless the carrier has relieved the driver from duty.[1]
Exceptions: Adverse Conditions, Short-Haul and Personal Conveyance
Dispatchers often hear about exceptions that will “buy a couple of hours”. Each one has conditions, and none is a general extension.
- Adverse driving conditions. A driver who meets adverse driving conditions and, because of them, cannot safely complete the run within the normal limits may drive up to two additional hours beyond the maximum allowed under 395.3(a), to complete the run or to reach a place offering safety for the occupants and security for the vehicle and its cargo.[3] The definition covers snow, ice, sleet, fog, other adverse weather, or unusual road or traffic conditions that were not known, and could not reasonably be known, to the driver before starting the duty day or to the carrier before dispatch.[1] Daily traffic around the port that anyone could have predicted is unlikely to fit that wording; a crash closure that happened after dispatch may. The driver and the carrier make that call.
- Short-haul (150 air-mile) exception. A driver who works within a 150 air-mile radius (172.6 statute miles) of the normal work reporting location, returns there and is released within 14 consecutive hours, and has at least 10 consecutive hours off between each 14 hours on duty is exempt from the record of duty status requirements in 395.8 and 395.11.[3] Drivers who qualify for the short-haul exceptions are also exempt from the 30-minute break rule.[2] It does not add driving time; it changes the paperwork and the break rule for local work.
- Personal conveyance. FMCSA guidance lets a driver log movement of the vehicle as off duty only when the driver has been relieved from work. One appropriate use it lists is time spent traveling to a nearby, reasonable, safe location to get required rest after loading or unloading, and that place must be the first such location reasonably available. The guidance says the vehicle may be used this way even when it is loaded, and that carriers can set stricter rules or ban personal conveyance.[4] It also lists inappropriate uses, including moving the truck to enhance the carrier’s operational readiness, such as bypassing available rest locations to get closer to the next stop, and continuing a trip to fulfill a business purpose.[4] As published in 2018, the guidance stated it would expire June 7, 2023, so check FMCSA’s current guidance and your carrier’s policy before relying on it.[4]
Put simply: personal conveyance can get an out-of-hours driver from a receiver’s gate to the nearest safe place to rest. It cannot be used to finish the delivery.
Your Options When the Clock Runs Out
Every legal option does one of three things: the driver stops and rests, a different driver takes over, or the freight moves to a different truck.
- Safe, legal parking and a reschedule. The driver stops where the truck and cargo are secure, takes the 10 hours off, and the appointment is moved. This is the default when nothing else is arranged in time. Call the receiver early: a missed appointment often goes to the back of the line.
- Relay or second driver. A fresh driver with available hours meets the truck and takes it the rest of the way. It works when the carrier has a driver nearby and the handoff point is safe and legal for the truck.
- Team on the next attempt. If the load is long or time-critical and keeps missing, a team lets one driver rest while the other drives. Each driver still has individual limits; a team does not suspend the rules.
- Drop the trailer. If the receiver accepts drop trailers, the driver leaves the loaded trailer and the receiver unloads later. See live unload vs. drop trailer. Only do this where the location is secure and the receiver, shipper and carrier agree on who is responsible for the trailer.
- Cross-dock the freight to another truck. If the driver can legally reach a dock, the freight can be unloaded there and reloaded onto a truck with a driver who has hours. It also helps when the load is going to more than one receiver. See cross-docking in the glossary.
- Unload and stage until the receiver is ready. When the receiver cannot take the freight until a later date, unloading at a dock and holding it in short-term storage frees the truck and driver instead of keeping both waiting.
Decision Table: Situation, Option, What to Arrange
| Situation | Best option | What to arrange |
|---|---|---|
| Driver can reach a safe stop but not the receiver | Park legally and reschedule | A secure parking spot within the driver’s remaining hours, a new appointment, and a note to the customer with the new delivery time. |
| Stuck at the shipper, 14-hour window almost gone, receiver is close | Relay driver or reschedule | A driver with available hours, a handoff point, and a receiver who will hold or move the appointment. |
| Crash closure or sudden storm after dispatch | Adverse driving conditions may apply | The driver’s own judgment, the carrier’s confirmation, and a note on the record of duty status. Still plan a safe stop if the extra time is not enough. |
| Just unloaded, out of hours, receiver will not let the truck stay | Personal conveyance to the nearest safe rest location, if the carrier allows it | Confirm the carrier’s policy, confirm the driver is fully relieved from work, and identify the first reasonably available safe location. |
| Receiver accepts drop trailers | Drop the trailer | Written agreement on the drop, a secure location, and who returns the empty trailer. |
| Load must keep moving and a dock is within legal reach | Cross-dock to another truck | A dock appointment, an outbound truck and driver with hours, and matching paperwork for the new carrier. |
| Receiver cannot take the freight for days | Unload and stage at a dock | Storage terms, a release process, and an outbound truck booked for the new date. |
| Long, time-critical lane that keeps running out of hours | Team or planned relay next time | Rebuild the plan with realistic dock times instead of solving it again on the road. |
Dispatcher Checklist
- Get the real numbers from the driver. Driving time left, time left in the 14-hour window, time since the last 30-minute break, and weekly hours left.
- Count the wait as on duty. Unless the driver has been relieved from duty, time at the shipper is burning the window.
- Find the safe stop first. Know where the truck can legally park before the hours run out, not after.
- Call the receiver early. Ask whether the appointment can move, whether they take drop trailers, and their latest receiving time.
- Check for a relay. Is there a driver with hours who can reach the truck before the window closes?
- Check for a dock. If the freight has to keep moving or wait somewhere, which dock can the driver reach legally, and is an outbound truck available?
- Do not lean on exceptions you cannot document. Adverse driving conditions and personal conveyance have specific conditions. Leave those calls to the driver and the carrier’s safety team.
- Record the timeline. Arrival time, loading start and finish, and when hours ran out. You will need it for any detention or layover claim.
- Tell the customer once, clearly. The new delivery time and the plan, not a running commentary.
Never ask a driver to drive past the limit
The limits in 49 CFR 395.3 apply to the driver and to the carrier that permits or requires the driving.[2] A missed appointment is a scheduling problem. A driver pushed past the limit is a safety and compliance problem for everyone in the chain.
Who Pays: HOS Is Not Detention
Detention is a charge for the truck’s waiting time beyond the free time agreed in the rate or contract. Running out of hours is the consequence that can follow a long wait. When a driver runs out of hours at or near a facility, the costs that may follow, such as an overnight stay or a reschedule, depend on the rate confirmation, the carrier’s accessorial terms and the shipper or receiver agreements. This guide does not repeat how those charges work; see who pays when a truck driver waits and the detention glossary entry. For container equipment clocks, which are a different thing again, see demurrage vs. detention.
Illustrative Example
This is an illustrative scenario, not a real customer job. A driver picks up a loaded trailer at a shipper in North Jersey for a receiver in Pennsylvania. Loading runs long, and by the time the doors close, most of the 14-hour window is gone. Traffic near Port Newark is heavy, as it is most afternoons, so the adverse driving conditions exception does not fit. The driver has enough time to reach a dock in Central New Jersey but not the receiver.
The dispatcher has three choices. Park and reschedule for the next day, which keeps the truck and driver tied up. Send a relay driver, but none is available before the window closes. Or book a dock appointment, have the driver deliver there within the remaining hours, and have the freight cross-docked onto a truck with a fresh driver the next morning. The dispatcher picks the dock, calls the receiver to move the appointment, and logs the shipper delay for the detention conversation that follows.
Where RapidShips Fits
RapidShips is a warehouse-based 3PL at 25A Cotters Lane, East Brunswick, NJ 08816, about 30 road miles from Port Newark, with 3 dock doors and dock operations 24/7 by appointment. When a load needs to change trucks, we handle the dock work: truck-to-truck cross-docking, transloading, short-term storage and staging and freight rework. We are not a freight broker, we do not provide trucks or drivers, and we do not offer truck parking. Your carrier brings the freight in and your carrier picks it up. To check whether a dock appointment fits your timeline, call 800-376-2808.
