The “5/5” Split Pilot Program – Real Flexibility or a New Headache?
This is the kind of FMCSA change that sounds small, but can hit your clock, your ELD logs, and your inspection risk if you misunderstand it.
FMCSA has proposed a Flexible Sleeper Berth Pilot Program that would test new split sleeper berth options like a 5/5 split sleeper berth and a 6/4 split. This is not a nationwide Hours of Service rule change today — it’s a limited pilot so FMCSA can measure safety and fatigue outcomes before doing anything bigger.
Think of it like a “test lane.” They run it with a small group, track results, then decide what should (or shouldn’t) become policy.
1) What is the “5/5” split pilot program?
It’s a proposed pilot where approved drivers would be allowed to meet the 10-hour off-duty requirement using split combinations that aren’t allowed under the standard rule today.
FMCSA’s proposal targets the part of the split sleeper berth provision that currently requires:
- two qualifying rest periods (no more than two), and
- one period must be at least 7 consecutive hours in the sleeper berth, and
- the paired periods must total at least 10 hours.
That 7-hour sleeper minimum is written into the federal regulation. You can see it in the official Hours of Service rule under 49 CFR §395.1(g) (sleeper berth provision). Here’s the official text source: eCFR: 49 CFR Part 395.
FMCSA’s proposal would reduce that sleeper minimum from 7 hours down to 5 hours for pilot participants. That’s the change that makes a true 5/5 split possible.
2) Is a 5/5 split sleeper berth legal right now?
No. Under normal Hours of Service rules, a 5/5 split is not a standard-legal split.
FMCSA’s own guidance for the current split sleeper berth rule is clear: drivers can use a period of at least 7 consecutive hours in the sleeper berth paired with a period of at least 2 consecutive hours off-duty (off-duty, sleeper berth, or a combination), as long as the paired periods total at least 10 hours. (FMCSA’s explanation page is here: FMCSA: What rest periods qualify for split sleeper?.)
So here’s the straight talk: if you log a 5/5 split like it’s legal for everybody, you’re creating a problem that can show up later during an inspection, audit, or safety review.
3) Why does this pilot matter for drivers in the real world?
Because HOS flexibility only matters in the moments trucking gets ugly:
- Detention turns your “planned day” into clock damage.
- Traffic wipes out your buffer.
- Truck parking shortages force bad end-of-day decisions.
A 5/5 option (if it ever becomes broader policy) could help drivers rest when rest actually fits the day — instead of forcing a 7-hour sleeper block at the worst possible time.
But here’s the part drivers need to stay sharp on: “flexibility” can help drivers manage fatigue… or it can become another lever to pressure drivers to stretch the day. The point of the HOS rules is fatigue management — not squeezing more work out of the same 24 hours.
Engagement question (money + trust angle):
Do you trust FMCSA is testing the 5/5 split to help drivers rest smarter… or do you think carriers will use it to squeeze more work out of the same day?
Quick protect-your-butt checklist
- Don’t run a 5/5 split unless you’re officially in the pilot. Standard rule still requires the 7-hour sleeper period for split use.
- Make sure your ELD is compliant and properly registered. If you’re not sure, use the tools here to verify your ELD status and other compliance basics: FMCSA Compliance Tools.
- Save official sources. When rules change, scammers and “fake FMCSA help” sites pop up fast.
