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.
