What Counts as On-Duty Not Driving

The definition, in plain language

49 CFR 395.2 defines on-duty time as all time from when a driver begins to work, or is required to be in readiness to work, until the driver is relieved from work and all responsibility for performing work. The list under that sentence is the checklist. It includes waiting to be dispatched unless the carrier has relieved the driver; inspecting, servicing, or conditioning the vehicle; all driving time; all other time in or on the vehicle except time resting in a sleeper berth; loading or unloading, supervising or assisting, attending a vehicle being loaded or unloaded, remaining ready to operate, and giving or receiving receipts; repairing or attending a disabled vehicle; time spent providing a breath or urine sample, including travel, for the tests Part 382 requires when the carrier directs them; any other work in the service of a motor carrier; and any compensated work for someone who is not a motor carrier.

On-duty not driving is everything on that list except the driving. Drivers call it line 4. The nickname is not a softer form of off duty. It is work, recorded as work, that happens to have the wheels stopped.

The 11-hour limit counts driving only. Line 4 does not shrink the 11. The 14-hour window is consecutive hours after coming on duty, so line 4 inside that window uses it up. The 60 and the 70 are on-duty totals, so line 4 hits them exactly as driving does. A recap that ignores line 4 is not a recap. The driving cap itself is the 11-hour driving limit.

Fuel, pre-trip, post-trip, and paperwork

Inspecting and servicing the vehicle is on the list in so many words. The pre-trip, the fuel stop, adding oil, and the post-trip are on-duty not driving. Logging them off duty is false if the work happened. A 15-minute pre-trip is 15 minutes of the 14-hour window and 15 minutes of the weekly total. It is not 15 minutes of driving, which is the only relief the rule gives.

Paperwork is other work for the carrier. Bills, logs, trip envelopes, and the messages you answer because dispatch requires an answer are on duty. Doing them in the bunk does not convert them to sleeper berth. Sleeper berth is rest in the berth, not office time that happens to be horizontal.

Compensated work away from the truck still counts. A driver who spends the morning on a second job and the afternoon in the CMV brings the morning hours into the on-duty total. The weekly limit does not care that the other employer does not own a truck.

Live load and live unload

Loading or unloading, assisting, attending the vehicle while it is loaded or unloaded, staying ready to drive, and exchanging receipts are all on-duty time. A live load is line 4 for the time you are required to be there. It is not off duty because you are not the person on the forklift. Attending is enough.

If the operation is drop and hook and the carrier has relieved you, the time after you are actually released can be off duty or sleeper. The hook itself, the inspection, and the paperwork are still on duty. Do not paint the whole visit with the off-duty label you earned only at the end.

A receiver who makes you stand by for three hours is not donating off-duty time. Unless you are relieved, those three hours are on duty not driving. They can feel idle. Idle and required to stay is still on duty. The 14-hour window does not pause for the feeling.

Waiting under dispatch versus a true off-duty break

Waiting to be dispatched is on duty unless the carrier has relieved you from duty. Sitting near the phone because a load might tender is not off duty. A true off-duty break means you are relieved of work and of responsibility for the truck. You are not required to stay. You are not required to answer. The vehicle can sit without you.

Carriers should say the relief in a way both sides can repeat. You are released until this time is different from stay close, we might have a load. The second sentence is readiness to work. Readiness is the first line of the definition.

Off duty inside a day you already started does not, by itself, pause the 14 consecutive hours. It does keep those minutes off the 60 or 70, which is why the false off-duty dock is so common. The weekly total looks lighter. The supporting documents still show you at the dock. The rebuild puts the hours back.

Sleeper berth is not line 4

Sleeper berth is its own duty status. It is time resting in a sleeper berth as defined in the rules. It is not the passenger seat. It is not the driver's seat reclined. It is not the mattress with a laptop open on dispatch messages. Those are on duty if the work or the readiness continues, or they are simply not sleeper.

The passenger seat while the co-driver drives is time in the vehicle. The definition counts that as on duty except for the berth. Team drivers who log the passenger seat as sleeper or as off duty, while still on a dispatch and not in the berth, are misrecording the status. The 30-minute interruption can still be satisfied by on-duty not driving. You do not need a false sleeper line to get the break.

Do not use this page as a tour of ELD buttons. Select the status that matches the definition. If the device offers a personal-conveyance prompt, that prompt is not line 4 and it is not a dock.

A one-day example with both lines

Come on duty at 07:00. Pre-trip and paperwork until 07:30. That is 0.5 on-duty not driving. Drive until 11:30. That is 4.0 driving. Live unload from 11:30 to 13:30. That is 2.0 on-duty not driving. Drive until 17:30. That is 4.0 driving. Fuel and post-trip from 17:30 to 18:00. That is 0.5 on-duty not driving. Released at 18:00.

Driving total: 8.0 hours, inside the 11. On-duty not driving: 3.0 hours. On-duty total for the 60 or 70: 11.0 hours. The 14-hour window started at 07:00 and would have run to 21:00, and the work ended at 18:00, so the window was not the binding stop. A recap that writes down 8 hours, because that was the driving, is 3 hours short of the day the rule measures.

If the unload had been logged off duty, the ELD would show 8 on-duty hours and the bills would show a two-hour door. The fiction is the gap. Put the 2.0 on line 4. Then see whether tomorrow's dispatch still fits the weekly total. Often it does not. That is the recap doing its job.

The same two hours, if they were 30 consecutive minutes or more with no driving, could also serve as the interruption required after 8 hours of driving. In this example the first driving block was only 4 hours, so the break was not yet required. When it is required, line 4 can be the interruption. The rules for that block are the 30-minute break after 8 hours of driving.
