HOS Rule Checker — which rule set applies to you?

Enter your two rest periods, pick your situation, and get the verdict under every rule set that exists — the standard 7/3 & 8/2 rule, the Flexible Sleeper Berth pilot (5/5 & 6/4), the McKee Foods exemption, and the Split Duty Period pilot — each with its regulation cited. Nothing is uploaded.

One rule engine, four rule sets. The 2020 rule gives everyone 7/3 and 8/2. The Flexible Sleeper Berth pilot unlocks 5/5 and 6/4 for enrolled drivers. Carrier exemptions like McKee Foods go further. The Split Duty Period pilot doesn't change splits at all — it pauses the 14-hour window.

Frequently asked

Can I legally run a 6/4 or 5/5?

Only under a special rule set — an enrolled FMCSA Flexible Sleeper Berth pilot participant, or a driver covered by a carrier exemption such as McKee Foods. Under the standard rule one period needs 7 consecutive sleeper-berth hours, so 6/4 and 5/5 fail.

Does the McKee Foods exemption apply to me?

Only if you are a team driver employed by McKee Foods Transportation, LLC (USDOT #1025678). The renewal runs April 20, 2025 through April 20, 2030 (docket FMCSA-2014-0071): two periods totaling 10 hours, neither under 2 hours — no 7-hour berth requirement.

What does the Split Duty Period pilot change?

Nothing about split validity. It pauses the 14-hour window for up to 3 hours per day of qualifying non-driving time, for enrolled drivers (docket FMCSA-2025-0194).

Is this a compliance determination?

No — an educational reading of published rules. Your ELD and carrier make the binding call; pilot enrollment is verified with FMCSA, not here.

FAQ

Can I legally run a 6/4 or 5/5 split sleeper berth?
Only under a special rule set: enrolled participants in the FMCSA Flexible Sleeper Berth pilot, or team drivers covered by a carrier exemption such as McKee Foods Transportation. Under the standard rule in 49 CFR 395.1(g)(1)(ii), one period must be at least 7 consecutive sleeper-berth hours, so 6/4 and 5/5 fail.
Does the McKee Foods exemption apply to me?
Only if you are a team driver employed by McKee Foods Transportation, LLC (USDOT #1025678). The renewal is in force April 20, 2025 through April 20, 2030 (docket FMCSA-2014-0071) and allows two periods totaling 10 hours with neither under 2 hours — including 6/4 and 5/5.
What does the Split Duty Period pilot change?
Nothing about split validity. It is a separate pilot (docket FMCSA-2025-0194) that lets enrolled drivers pause the 14-hour driving window for up to 3 hours per day of qualifying non-driving time: off duty, sleeper berth, or on-duty at a pickup or delivery location.
Is this checker a compliance determination?
No. It is an educational reading of published regulations and pilot terms. Your ELD and your carrier's safety department make the binding call, and pilot enrollment status is verified with FMCSA, not here.
