FMCSA Proposes Pilot to Let Drivers Pause 14‑Hour Driving Window

What the Pilot Proposes

FMCSA announced a new information collection request that will test a pilot program. The pilot would let commercial motor vehicle drivers pause their 14‑hour driving window for up to three hours of off‑duty, sleeper berth, or on‑duty/not‑driving time. The pause must occur at the location of a cargo delivery or pickup. The goal is to see if this flexibility improves drivers’ working conditions and keeps safety at current or higher levels.

Who Is Affected

The study will involve about 256 CMV drivers. FMCSA will compare driver fatigue and performance under current hours of service rules and under the split duty period exemptions. The data will help determine whether the pause option is viable.

What Carriers Should Check

Carriers, recruiters, and fleet managers should note that the pilot is still in the information‑collection phase. It is not a rule change yet. The proposal is open for public comment until December 7, 2026. Carriers should monitor the outcome and confirm how any future rule would apply to their operations.

Uncertainties and Next Steps

What remains unclear is whether the pause will be allowed in all situations or only under specific conditions. FMCSA has not yet defined the exact criteria for the pause location or how the three hours will be logged. Carriers should keep an eye on the final OMB approval and any subsequent guidance.
