Quick Answer
The 30-minute break rule (49 CFR 395.3(a)(3)(ii)) says you can't drive a property-carrying CMV once 8 cumulative hours of driving have passed without a break of at least 30 consecutive minutes away from the wheel. The break doesn't have to be off duty. Off duty, sleeper berth, on-duty not driving, or any consecutive mix counts. Short-haul drivers under 395.1(e) are exempt.
Key Takeaways
- The trigger is 8 hours of driving time, added up across the shift. Breaks and on-duty work don't count toward the 8 hours.
- The break must be 30 consecutive minutes with no driving. Two 15-minute stops separated by driving don't count.
- Fueling, loading, paperwork, a roadside inspection, or yard moves can all count, as long as the 30 minutes are unbroken.
- The break counts against your 14-hour window and doesn't add drive time to your 11-hour limit.
- Drivers using either short-haul exception in 395.1(e)(1) or (e)(2) are exempt, and passenger-carrier rules have no break requirement.
- The violation is cited as 395.3(a)(3)(ii).
“Under 49 CFR 395.3(a)(3)(ii), you can't drive a property-carrying CMV after 8 cumulative hours of driving unless you've had at least 30 consecutive minutes out of driving status. Off duty, sleeper berth, on-duty not driving, or a consecutive mix all count. Short-haul drivers under 395.1(e) are exempt.”
What is the 30-minute break rule?
The 30-minute break rule is one of the four core limits in the FMCSA hours of service rules, next to the 11-hour driving limit, the 14-hour window, and the 60/70-hour cap. It applies to property-carrying CMV drivers who are subject to part 395.
The regulation says driving "is not permitted if more than 8 hours of driving time have passed without at least a consecutive 30-minute interruption in driving status." So you can drive up to 8 hours total. To drive past 8, you need 30 straight minutes out of driving status first.
The current version took effect September 29, 2020. Before that, the break had to be off duty or in the sleeper berth, and the 8 hours ran on the clock from the end of your last off-duty or sleeper period, not on driving time. Older blogs and training material still describe the pre-2020 rule.
Does the 30-minute break have to be off duty?
No. Since the 2020 rule, any non-driving status counts: off duty, sleeper berth, on-duty not driving, or a combination of them, as long as the time is consecutive.
FMCSA's own example: 10 minutes off duty followed by 20 minutes fueling and doing paperwork (on-duty not driving) satisfies the break (FMCSA FAQ). It doesn't have to be a meal break, and you don't have to leave the truck.
What counts as a 30-minute break?
Any 30 unbroken minutes in which you are not in driving status. Under 49 CFR 395.2, driving time means time "at the driving controls of a commercial motor vehicle in operation."
These count, if they run 30 minutes straight:
- Off-duty time: lunch, a shower, a walk.
- Sleeper berth time, including the start of a 10-hour or split sleeper rest.
- On-duty not driving: fueling, a pre-trip or post-trip inspection, loading or unloading, waiting at the dock, paperwork.
- A roadside inspection that keeps you stopped at least 30 consecutive minutes (FMCSA FAQ, 2020).
- Riding in the passenger seat while your co-driver drives (on-duty not driving, or off duty when it falls in the 3-hour window next to a 7-hour sleeper period).
These don't count:
- Two shorter breaks with driving in between, even one minute of driving to pull up to the pump.
- A stop that your ELD still shows as driving.
When do you have to take the 30-minute break? A worked example
The driving clock only moves while you're driving. Here's a typical day after 10 hours off:
Time | Status | Driving since last 30-min break | Break needed? |
|---|---|---|---|
6:00 a.m. | On duty, pre-trip (15 min) | 0:00 | No |
6:15 a.m. | Driving until 10:15 a.m. | 4:00 | No |
10:15 a.m. | On duty, fueling (20 min) | 4:00 (20 min doesn't reset it) | No |
10:35 a.m. | Driving until 2:35 p.m. | 8:00 | Yes, before driving again |
2:35 p.m. | Off duty, lunch (30 min) | Resets to 0:00 at 3:05 p.m. | Satisfied |
3:05 p.m. | Driving until 6:05 p.m. | 3:00 | No, but the 11-hour limit is now used up |
Two things to notice. The 20-minute fuel stop didn't help because it was under 30 minutes. If you'd stretched it 10 minutes, the break would have been done at 10:45 a.m. and you could have driven straight through to your 11-hour limit.
The lunch break also counted against the 14-hour window, which closes at 8:00 p.m. here because you came on duty at 6:00 a.m. FMCSA confirms the break counts against the window. If you're planning around your weekly hours as well, see the 34-hour restart.
A split sleeper berth rest of 2 or more hours also covers the break, since it's well over 30 consecutive non-driving minutes.
Do personal conveyance and yard moves count toward the break?
Yard moves: yes. FMCSA says a yard move can be part of a 30-consecutive-minute break because yard-move time is on-duty not driving (FMCSA FAQ). The movement has to be a genuine yard move, logged under the ELD's yard move indicator.
Personal conveyance: don't rely on it. FMCSA treats personal conveyance as off-duty time and lets you combine it with other off-duty time for a 10- or 34-hour break. It hasn't published guidance saying 30 minutes of PC satisfies the break, and PC can't be used to move the load forward or extend your day. Take the break parked. See yard move vs personal conveyance for how each status is supposed to be used.
What are the 30-minute break exceptions?
The rule itself carves out the two short-haul exceptions. Other parts of 49 CFR 395.1 remove the break by exempting you from all of part 395 or from 395.3(a).
Exception | Citation | 30-minute break? |
|---|---|---|
150 air-mile short-haul (back and released within 14 hours) | 395.1(e)(1) | Not required |
Non-CDL short-haul (150 air miles) | 395.1(e)(2) | Not required |
Passenger-carrying CMVs | 395.5 | No break rule exists |
Agricultural operations during state planting/harvest seasons, within 150 air miles | 395.1(k) | Part 395 doesn't apply |
Livestock or commercial bees, while on the vehicle | 395.1(v), 395.1(u) | Not required |
Covered farm vehicles, utility service vehicles, railroad signal employees, pipeline welding trucks | 395.1(s), (n), (r), (x) | Part 395 doesn't apply |
Retail store deliveries, Dec. 10 to 25, within 100 air miles | 395.1(f) | 395.3(a) doesn't apply |
Alaska; motion picture production within 100 air miles | 395.1(h), 395.1(p) | 395.3(a) doesn't apply (their own limits apply) |
Two special cases still require the break but make it easier. Drivers attending Division 1.1, 1.2, or 1.3 explosives may count 30 minutes of attendance time if they do no other work, logged as on-duty with a remark (395.1(q)). Ready-mixed concrete drivers may count 30 minutes waiting with the truck at a job site or terminal (395.1(t)).
The 16-hour short-haul exception in 395.1(o) only waives the 14-hour limit. It doesn't exempt you from the break.
If you start a day as a short-haul driver and unexpectedly go past 150 air miles or 14 hours, you now need a log. FMCSA's 2013 guidance says you aren't in violation if the 8 hours had already passed when you found out, but you should annotate your log and take the break at the earliest safe opportunity.
How does your ELD track the 30-minute break?
Under the ELD technical specifications (appendix A to subpart B of part 395), the device automatically switches you to driving once the truck goes faster than a set threshold of no more than 5 mph. When you stop, it doesn't switch you out of driving right away. After 5 minutes without motion it asks you to confirm your status, and if you don't answer within 1 minute it changes you to on-duty not driving.
That's why your break clock may not start the moment you park. Change your status yourself when you stop.
The ELD rule doesn't require devices to flag HOS violations. FMCSA notes some providers add violation warnings as an extra feature, and that a device not updated for the 2020 rules may flag breaks wrong. Ask your provider what yours shows. Lucid ELD support can walk you through how the HOS clocks display in the driver app.
What are the most common 30-minute break violations?
Inspectors cite missed breaks as 395.3(a)(3)(ii). These mistakes cause most of them:
- Breaking the 30 minutes. Moving the truck to a fuel island or parking spot in the middle of the break restarts it.
- Leaving the ELD in driving. A quick stop left in driving status isn't a break.
- Using pre-2020 math. Counting on-duty hours, or thinking the break must be off duty, leads to confusion and bad planning.
- Assuming you're still short-haul. Once you leave the 150 air-mile radius or pass your duty-day limit, the break applies.
- Mislabeling driving as yard moves or PC. It's a falsification risk, not a workaround.
- Planning to the minute. Traffic turns an 8:00 plan into an 8:05 violation.

FAQ
Does the 30-minute break reset my 11-hour or 14-hour clock?
No. It only resets the 8-hour driving count. FMCSA says the break counts against your 14-hour window, and it adds no time to your 11-hour driving limit.
Can I split the 30-minute break into two 15-minute breaks?
No. The 30 minutes must be consecutive. You can combine statuses back to back, such as 15 minutes on-duty not driving followed by 15 minutes off duty, but driving in between restarts the count.
Do I need a 30-minute break if I only drive 8 hours?
No. The rule bars driving after more than 8 hours of driving time without a break. If your day has 8 hours of driving or less, you don't need one.
Does a sleeper berth period count as the 30-minute break?
Yes. Any sleeper berth period of 30 consecutive minutes or more counts, including a 2-hour or 7-hour split sleeper period.
Do team drivers need the 30-minute break?
Yes, each driver does. Time riding in the passenger seat while your partner drives is non-driving time, so 30 straight minutes of it satisfies your break.
Has the 30-minute break rule changed in 2026?
No. As of October 2026 the rule is the same as the 2020 version. FMCSA's split duty period pilot is a study capped at about 256 drivers and doesn't change the rule for anyone else.
