The 30-minute break rule for truck drivers, explained

The 30-minute break rule says you may not drive once you have driven 8 hours without a break of at least 30 consecutive minutes from driving. The break can be off duty, in the sleeper berth, or on duty not driving, so a 30-minute live load or inspection counts. The rule applies to property-carrying drivers and is in 49 CFR 395.3(a)(3)(ii).

What the rule says

The current text reads: "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." It then lists what counts: off-duty time, sleeper berth time, on-duty not driving time, or a combination of them.

This wording comes from FMCSA's 2020 amendment (85 FR 33452, June 1, 2020). If you learned an older version of the rule, check your habits against the current text: the trigger today is 8 hours of driving time, and on-duty not driving time counts as the break.

How the 8 hours are counted

The count is cumulative driving time since your last qualifying break. FMCSA's driver's guide puts it plainly: the break is required after 8 cumulative, not consecutive, driving hours. Three points follow from that:

• Time spent loading, fueling, inspecting or waiting doesn't add to the 8 hours, because it isn't driving.
• Stops shorter than 30 minutes don't reset the count. Two 15-minute stops are two short stops, not one break.
• Once you complete a 30-minute interruption, the count starts over at zero.

The break also has to be consecutive. You can combine statuses, such as 15 minutes on duty fueling followed directly by 15 minutes off duty, but the 30 minutes can't have any driving in the middle.

Worked examples

Each example assumes a driver who comes on duty at 6:00 a.m. after 10 consecutive hours off, so the 14-hour window closes at 8:00 p.m.

A straight run

1. 6:15 a.m. to 2:15 p.m.: drives 8 hours with no stop longer than a few minutes.
2. 2:15 p.m.: the 8-hour mark. The driver must not drive again until taking 30 consecutive minutes away from driving.
3. 2:15 to 2:45 p.m.: off duty at a rest area.
4. 2:45 to 5:45 p.m.: drives 3 more hours, reaching the 11-hour driving limit with the window still open.

A live load that counts as the break

1. 6:30 to 10:30 a.m.: drives 4 hours.
2. 10:30 to 11:15 a.m.: live load, logged on duty not driving. At 45 consecutive minutes, it satisfies the break.
3. 11:15 a.m. to 6:15 p.m.: drives 7 hours, for 11 in total. The 7 hours since the load stay under 8, so no second break is needed.

Short stops that don't add up

1. Drives 3 hours, stops 15 minutes for fuel.
2. Drives 3 hours, stops 20 minutes to eat.
3. Drives 2 hours. That makes 8 hours of driving, and neither stop reached 30 consecutive minutes.
4. The driver must now take 30 consecutive minutes away from driving before driving again.

An early break

A break taken early resets the count, which can mean a second break later. If you take your break after 2 hours of driving and then drive 9 more hours, you pass 8 hours since the break and need another 30 minutes before the 11th hour.

The break and your other clocks

The 30-minute break does not pause or extend the 14-hour window. It sits inside the window like any other stop, as the 11-hour and 14-hour rules guide explains.

How you log the break affects your weekly total. A break logged on duty not driving counts toward your 60/70-hour limit, while a break logged off duty or in the sleeper berth does not. See the 70-hour rule and 34-hour restart guide for how that total works.

Who doesn't need the break

• Property-carrying drivers who qualify for the 150 air-mile short-haul exception in 395.1(e)(1).
• Drivers of property-carrying vehicles that don't require a CDL who qualify for the short-haul exception in 395.1(e)(2).
• Passenger-carrying drivers. Their limits are in 49 CFR 395.5, which has no 30-minute break requirement.

Common mistakes

• Treating two short stops as one break. The 30 minutes must be consecutive.
• Stopping for 25 minutes and calling it the break. Anything under 30 consecutive minutes doesn't count.
• Assuming the break must be off duty. On-duty not driving time and sleeper berth time also qualify.
• Counting on-duty hours instead of driving hours. Loading and waiting don't move you toward the 8-hour mark.
• Expecting the break to give back time on the 14-hour clock. It doesn't.
• Forgetting the second break. If you drive more than 8 hours after your first break, you need another one.

How Fort Route helps

When you plan a trip, Fort Route places the legal 30-minute break at a real truck stop or rest area along your route, and the legal arrival time already includes it. You enter your current clocks yourself, since there is no ELD sync.

While you drive, the Break ring in the hours of service view shows how much driving you have before the break is due, alongside the Drive, Shift and Cycle rings, and HOS reminders come up along the way. Fort Route is a planning aid; your ELD record is the legal record of your hours.
