What the final rule changes
FMCSA's final rule changes one number in 49 CFR 390.23(b): the automatic relief period tied to a regional declaration of emergency returns from 14 days to 30 days. The rule was published and became effective October 5, 2026.
The trigger remains a regional emergency declaration issued by a state governor, the governor's authorized representative or FMCSA. The change reverses the shorter period adopted in 2023 after FMCSA reconsidered petitions and a 2026 proposal.
Who can use the relief
The automatic exemption is limited to commercial motor vehicles providing direct assistance to restore essential services or supplies. The rule identifies relief from the federal hours-of-service provisions in 49 CFR 395.3 and 395.5; it is not a blanket waiver for every load operating in an affected region.
Thirty days is the maximum automatic window, not a guaranteed month. If the declared emergency period ends sooner, the automatic relief ends with it. FMCSA can separately extend relief beyond 30 days when warranted.
What drivers and carriers should verify
Before using emergency relief, dispatchers and drivers should keep the controlling declaration available, confirm that the load is providing direct assistance, check its geographic and commodity scope, and note the declaration's start and end times.
Normal safe-operation duties still apply. The final rule changes the duration of qualifying automatic relief; it does not authorize unsafe driving, erase recordkeeping outside the exemption or extend relief to routine commercial freight merely because it is near an emergency.
