The Federal Motor Carrier Safety Administration restored a 30-day automatic hours-of-service exemption for truckers delivering direct emergency assistance, doubling the relief window that stood from October 2023 through October 2026.

A final rule published Monday in the Federal Register extends the automatic regional emergency exemption from 14 days back to 30 days. The rule took effect the same day and reverses a 2023 final rule that had shortened the period.

What does the rule actually change?

The exemption applies to commercial motor vehicles providing direct assistance after a regional emergency declaration issued by a state governor, a governor's authorized representative, or FMCSA itself. It releases covered drivers from federal HOS regulations under 49 CFR 395.3 and 395.5.

FMCSA stressed that the relief targets vehicles directly supporting emergency response, not every truck operating inside a disaster zone. The agency framed the policy change as cutting red tape around disaster relief runs, not as a blank check to extend driving hours indefinitely across an affected region.

The 30-day window is also a maximum, not a guaranteed month of relief. If the underlying emergency declaration expires earlier, the exemption ends with it. FMCSA retains authority to extend relief beyond 30 days when conditions warrant.

Why did FMCSA reverse the 2023 cut?

The agency first shortened the automatic exemption in October 2023. Reconsideration petitions soon followed. In January 2026, FMCSA proposed restoring 30 days and accepted public comments over a 60-day window, receiving 17 submissions.

A coalition of trade groups — the Owner-Operator Independent Drivers Association, Commercial Vehicle Safety Alliance, National Propane Gas Association, Gases and Welding Distributors Association, National Energy & Fuels Institute, and the Shippers Coalition — backed the change. The Montana Department of Transportation also signed on independently.

Five state transportation departments — Idaho, Montana, North Dakota, South Dakota, and Wyoming — filed a joint letter supporting the rule. They told FMCSA there was "no record of adverse safety effects" from emergency HOS regulatory relief.

One individual opposed the move, arguing that the 14-day cap forced more frequent reviews of whether relief remained necessary. FMCSA rejected that argument, citing the administrative problems the shorter window created. National Tank Truck Carriers neither supported nor opposed the proposal, calling the practical impact on tank truck operations likely limited.

A separate commenter asked FMCSA to extend the automatic cap to 90 days. The agency declined, pointing to its experience that regional emergency exemptions rarely need more than 30 days to restore essential services and supplies.

How much paperwork will carriers actually save?

FMCSA framed the change as a paperwork fix more than an economic shift. The agency projects that annual extension requests will fall from about 50 to roughly 25.

Industry burden tied to those requests drops to an estimated 6.25 hours and $533 per year. Federal review costs run about $896 annually. Combined, eliminating roughly 25 requests each year saves carriers and the government approximately $1,429 per year.

For carriers, the operational value sits in longer-tail events: hurricanes that linger inland, wildfire evacuations that span a month of supply convoys, or ice storms that shut down power for weeks. Under the 2023 regime, drivers and dispatchers had to pause and refile paperwork once relief hit day 15. The longer window pulls that step out of the first month of response.

FMCSA's reversal arrived with multi-stakeholder support that bridges safety advocates, energy distributors, and rural state DOTs. The first full test of the restored 30-day window will come during the 2026 hurricane season, when carriers will measure recovery logistics against a regulatory clock that no longer resets at 14 days.
