The sleeper berth split is one of the most useful tools a truck driver has, and one of the most confusing. Used well, it lets you turn a long wait at a shipper into part of your 10 hour break, so you're not burning your 14 hour clock. Used wrong, it creates a violation that shows up on your logs for everyone to see. Here's how it works, based on 49 CFR 395.1(g), checked October 2026.

How Split Sleeper Works

Normally, property carrying drivers need 10 consecutive hours off before driving again. The sleeper berth rule gives you another way to get the equivalent of those 10 hours. You can take two rest periods instead of one, as long as:

One period is at least 7 consecutive hours in the sleeper berth.
The other period is at least 2 consecutive hours, either off duty, in the sleeper berth, or a mix of the two.
The two periods add up to at least 10 hours.
Driving before and after each rest period, added together, doesn't go past 11 hours or break the 14 hour limit.

The big benefit is this. Under 395.1(g)(1)(iii), neither qualifying rest period counts against your 14 hour window. And your limits are recalculated from the end of the first of the two rest periods. That's what makes the split so handy for drivers stuck waiting.

The periods can be taken in either order. You can do the long sleeper period first and the short break second, or the other way around.

Common split combinations

Split	Long period	Short period	Allowed?
8/2	8 hours in sleeper	2 hours off duty or sleeper	Yes
7/3	7 hours in sleeper	3 hours off duty or sleeper	Yes
7.5/2.5	7.5 hours in sleeper	2.5 hours off duty or sleeper	Yes
6/4	6 hours in sleeper	4 hours off	No, the long period must be 7 hours or more
8/1.5	8 hours	1.5 hours	No, the short period must be 2 hours or more

8/2 Split Example

Jamal starts his day at 6:00 a.m. after a full 10 hour break.

6:00 a.m. to 11:00 a.m.: drives 5 hours.
11:00 a.m. to 1:00 p.m.: 2 hours off duty at a truck stop. This is his short period.
1:00 p.m. to 7:00 p.m.: drives 6 hours. That's 11 hours of driving total, so he's at his limit.
7:00 p.m. to 3:00 a.m.: 8 hours in the sleeper berth. This completes the split.

Now the recalculation. His limits start counting from the end of the first rest period, which was 1:00 p.m. Since 1:00 p.m. he has driven 6 hours. So when he wakes up at 3:00 a.m., he has 5 hours of driving available (11 minus 6). His new 14 hour window is also counted from 1:00 p.m., but the 8 hour sleeper period doesn't count against it. So he has 14 minus 6 hours of on duty time between 1:00 and 7:00, leaving 8 hours of window. He'll pair the 8 hour sleeper period with his next qualifying break to keep the cycle going, or take a full 10 off to reset.

7/3 Split Example

Rachel arrives at a receiver at 2:00 p.m. after driving 4 hours. They tell her she won't be unloaded until 9:00 p.m. Instead of sitting on duty and watching her 14 hour clock run, she goes into the sleeper.

Started at 10:00 a.m. Drove until 2:00 p.m. (4 hours driving).
2:00 p.m. to 9:00 p.m.: 7 hours in the sleeper berth. This is her long period.
9:00 p.m. to 10:00 p.m.: 1 hour on duty while unloaded.
10:00 p.m. to 3:00 a.m.: drives 5 hours.
3:00 a.m. to 6:00 a.m.: 3 hours off duty. This completes the 7/3 split.

After 6:00 a.m., her clocks are recalculated from the end of the first period, 9:00 p.m. Since then she's driven 5 hours, so she has 6 hours of driving left. Without the split, she'd have been stuck at the receiver with her 14 hour clock long gone. That's the real value here.

How ELDs Log Split Sleeper

Good news: most modern ELDs calculate the split for you. When you log a qualifying sleeper period, the ELD looks back for a matching short period and adjusts your clocks. A few things to know:

The status has to be right. The 7 hour period must be logged as sleeper berth, not off duty. If you log 8 hours as off duty in a motel, it won't count as the long part of a split.
Clocks may look odd until the pair completes. Until both periods are done, your ELD may show less time than you expect. Once the second period ends, the recalculation kicks in.
Not every ELD shows the math clearly. Some apps show a split sleeper indicator. Others just adjust the numbers. If you're not sure, check your provider's driver guide, which has to be in the cab anyway under 395.22(h).
Your carrier must allow it. Some fleets turn off split sleeper in their ELD settings. Ask before you plan around it.

If your ELD doesn't handle splits well, it can cost you real hours. That's a fair reason to look at other options. Our hours of service calculator handles the basic clocks, and the full rules are in our hours of service guide.

Common Mistakes

Logging the long period as off duty. At least 7 hours has to be in the sleeper berth itself. Time spent in a hotel or a lounge doesn't qualify for the long period.
Making the short period too short. A break of 1 hour and 45 minutes doesn't count. The short period has to be at least 2 full consecutive hours.
Counting driving time wrong. The driving before and after each rest period has to add up to 11 hours or less. Drivers sometimes count from the start of the day instead of the right rest period.
Forgetting the 30 minute break. A split doesn't remove the 30 minute break requirement. The good news is that a 2 or 3 hour rest period also satisfies it.
Using split sleeper on the non CDL short haul option. Drivers using 395.1(e)(2) can't use the sleeper berth provisions.
Riding in the passenger seat. Team drivers have a separate rule. The sleeper berth rule allows at least 7 consecutive hours in the berth plus up to 3 hours in the passenger seat, before or after, adding up to at least 10 consecutive hours. This is a different option from the two period split.

When in doubt, take a full 10 hours. It's always legal. And if you're picking a new ELD, ask the provider to walk you through how it shows a split on screen. Then compare ELD quotes to find one that makes it easy.

Frequently Asked Questions

What is the 7/3 split?

It is a split sleeper berth break with at least 7 consecutive hours in the sleeper berth and at least 3 hours off duty or in the sleeper, totaling 10 hours. Neither period counts against the 14 hour window.

Does the 2 hour break count against my 14 hours?

No, as long as it is paired with a qualifying 7 hour sleeper period and the two add up to at least 10 hours. Under 395.1(g)(1)(iii), qualifying rest periods do not count against the 14 hour window.

Can I take the short break first?

Yes. The rule does not require a particular order. The long and short periods can come in either order.

Can I split 6 and 4?

No. One period has to be at least 7 consecutive hours in the sleeper berth.

Does the 2 hour break satisfy the 30 minute break?

Yes. Any off duty, sleeper berth or on duty not driving period of at least 30 consecutive minutes satisfies the 30 minute break.
