Split Sleeper Berth Rules Explained: The 8/2 and 7/3 Split (2026)

The sleeper-berth provision lets you break your 10 hours off into two pieces without losing your day. Used right, it can add hours back to your 14-hour window.

The normal rule first

Normally you need 10 consecutive hours off duty to reset your 11-hour driving limit and 14-hour window (see our HOS rules guide). The split sleeper provision is the one legal way to take that 10 hours in two chunks instead of one.

The only two valid splits

You may pair your rest as an 8/2 or a 7/3 split:

Split	Longer period	Shorter period
8/2	≥ 8 hours in the sleeper berth	≥ 2 hours off duty or sleeper
7/3	≥ 7 hours in the sleeper berth	≥ 3 hours off duty or sleeper

Rules that always apply:

The two periods must add up to at least 10 hours.
One period must be at least 7 consecutive hours in the sleeper berth.
The other period must be at least 2 hours, spent off duty or in the sleeper.
A 6/4 or 5/5 split does not qualify — it won't pause your clocks.

Why the split helps: the 14-hour clock

Here's the key benefit. When you take a qualifying split, neither rest period counts against your 14-hour window. Each qualifying break effectively pushes your driving window later, so you recover drive time you'd otherwise lose sitting in traffic or waiting to load.

A worked example (8/2)

Say you come on duty at 6:00 AM and drive. At 2:00 PM you've been on duty 8 hours. You take 8 hours in the sleeper berth (2:00 PM–10:00 PM). When you come back, your available 14-hour window is recalculated as if that 8-hour period never happened — you still have driving time left based on the 2 hours you were on before it. Later, you complete the pair with a 2-hour off-duty period, and together the 8 + 2 gives you a full reset.

Common mistakes

Logging the short period as on-duty. It must be off duty or sleeper — not on-duty-not-driving.
Making the sleeper period under 7 hours. Then it's not a valid split at all.
Assuming any two rests pair up. Only the most recent qualifying periods pair together.

How an ELD handles the math for you

Split-sleeper math is where paper logs and cheap apps get drivers violations. TruckSpot ELD detects qualifying 8/2 and 7/3 pairs automatically and recalculates your available driving and window in real time, so you always see the correct hours — not a guess.

Frequently asked questions

What splits are allowed for the sleeper berth?

You can pair an 8/2 or 7/3 split. One period must be at least 7 consecutive hours in the sleeper berth; the other must be at least 2 hours off duty or in the sleeper. Together they must add up to at least 10 hours.

Does the split sleeper pause my 14-hour clock?

Yes. When you use a qualifying split, neither of the two rest periods counts against your 14-hour driving window — the window is effectively extended by the paired rest.

Can I do a 6/4 or 5/5 split?

No. The only valid pairings are 8/2 and 7/3. One period must be at least 7 hours in the sleeper berth. A 6/4 or 5/5 does not qualify and will not pause your 14-hour clock.
