The Fuel Transportation HOS Waiver: What It Actually Waives (and What It Doesn't)

FMCSA has an hours-of-service waiver in effect for motor carriers and drivers transporting gasoline and diesel fuel, from 12:00 a.m. on September 16, 2026 through 11:59 p.m. on December 16, 2026. It's the first nationwide HOS waiver since the COVID-era declarations, and DOT issued it in anticipation of fuel-supply pressure through the back half of the fall.

If you haul fuel, the headline is simple: 16 driving hours in any 24-hour period instead of 11. The part that gets carriers in trouble is everything the waiver leaves untouched — and the fact that your ELD will keep flagging violations the whole time it's running.

This guide covers what the waiver actually changes, who's eligible, what remains fully enforceable, how to log and document it, and what happens on December 16.

What the waiver actually waives

FMCSA waived the driving limits in 49 CFR §395.3 — the section that contains all four of the property-carrying limits carriers plan around:

• the 11-hour driving limit
• the 14-hour on-duty window
• the 30-minute break after 8 cumulative hours of driving
• the 60/70-hour limit over 7 or 8 consecutive days

In their place, the waiver substitutes its own, much shorter set of limits:

• A driver must not drive more than 16 hours in any 24-hour period.
• The driver must take a minimum 6 consecutive hours in the sleeper berth in each 24-hour period. If the truck has no sleeper berth, that becomes a minimum 8 consecutive hours off duty in each 24-hour period.

That's the whole trade. You gain five driving hours and lose the 14-hour clock, the mid-shift break, and the weekly cap. You take on a hard 16-hour ceiling and a mandatory consolidated rest period inside every rolling 24 hours.

One thing worth reading carefully: the waiver's rest requirement is expressed per 24-hour period, not as the familiar "10 consecutive hours off duty before you may drive again" reset in §395.3(a)(1). Fleets that build schedules against the wrong one of those two structures are the fleets that discover the problem at a roadside inspection.

Who qualifies — and who's excluded

The waiver is narrower than "fuel haulers get more hours." To operate under it:

• The transportation must be gasoline or diesel fuel, in interstate commerce, in a commercial motor vehicle. The waiver was issued for fuel movement — it isn't a general tank-truck waiver, and it isn't a blanket for whatever else is on the trailer.
• The driver must hold a valid CDL with all endorsements required for the vehicle and the commodity being hauled.
• The driver must not be subject to an out-of-service order, disqualification, or loss of driving privileges.
• The carrier's safety rating matters. Carriers rated Conditional or Unsatisfactory are not eligible. If FMCSA has downgraded you, the waiver is not available to you — and operating under it anyway is a §395.3 violation with an aggravating factor attached.
• The driver must carry a copy of the waiver, physical or digital, and produce it to law enforcement on request.

Two practical consequences of that list. First, eligibility is a carrier-level question you should answer once, in writing, before any dispatcher starts building 16-hour runs — not a question each driver settles at the scale house. Second, FMCSA can ask a carrier to account for how it used the waiver, so "we think we qualified" is not a filing position.

What the waiver does not touch

This is the section that matters most, because a waiver from §395.3 is a waiver from §395.3 and nothing else. Every one of these stays fully enforceable for the entire 90 days:

• §392.3 — driving while fatigued or ill. A driver who is too tired to safely operate may not operate, waiver or no waiver. This is the rule inspectors reach for when a log is technically legal and the driver plainly isn't. The waiver does not create a defense here; if anything, a 16-hour day makes §392.3 the more likely citation.
• Records of duty status and the ELD rule (§395.8, §395.20–§395.38). The waiver relieves the driving limits. It does not relieve recording. Drivers keep logging, ELDs keep running, and the records remain subject to inspection and to the 6-month retention requirement. (Compare this to FMCSA's May 2026 fertilizer waiver, which did include ELD relief in select states — commodity waivers are not interchangeable, and you cannot borrow terms from one for another.)
• All hazardous materials regulations (49 CFR parts 171–180). Gasoline is a placarded Class 3 material. Shipping papers, placarding, loading and unloading requirements under §177.834 and §177.837, the hazmat endorsement, HM registration, emergency response information — none of it moves. An HOS waiver has no effect on hazmat law.
• CDL, drug and alcohol testing, and Clearinghouse obligations (parts 383, 382). Pre-employment queries, random testing rates, and the annual Clearinghouse query all continue on schedule.
• Driver qualification files (§391). Medical certificates, MVR reviews, and every other §391.51 document expire on their own calendar. See the DQ file checklist for the full list.
• Vehicle condition, inspection, and maintenance (parts 393, 396). Annual inspections, DVIRs, brake and tire standards — unchanged.
• Insurance minimums, size and weight limits, and state law.

Put plainly: the waiver buys you driving hours. It does not buy you slack anywhere else, and running tired drivers or expired paperwork under cover of a waiver is how a flexibility measure turns into an intervention.

Waiver vs. exemption vs. emergency declaration

Carriers use these three words interchangeably. FMCSA does not, and the differences decide how long relief lasts and whether you need to do anything to claim it.

A waiver (49 CFR part 381, subpart B). Temporary relief from one or more FMCSRs for a non-emergency, unique event, lasting up to three months, subject to whatever conditions the Administrator imposes. This is the mechanism behind the current fuel waiver — and it explains the exact dates: September 16 to December 16 is three months to the day. A waiver cannot be stretched past that cap; FMCSA would have to issue a new one.

An exemption (part 381, subpart C). Relief for a person or class of persons for up to five years, renewable. Exemptions require a Federal Register notice and public comment, and FMCSA must find that the exemption achieves a level of safety equivalent to or greater than what the rule provides. That bar is real: in December 2025 FMCSA denied the National Propane Gas Association's application for a recurring December 15 – March 15 HOS exemption, finding it would not meet the equivalent-safety standard. If you heard that propane haulers have a standing winter HOS exemption, they do not.

An emergency exemption (§390.23). This is the automatic relief that attaches when an emergency is declared, and FMCSA's 2023 Clarification to the Applicability of Emergency Exemptions final rule narrowed it substantially — many carriers are still working from the pre-2023 version. As it stands now:

Note the fuel-specific carve-out in that table. A Governor's declaration based on a residential heating fuel shortage — heating oil, propane, natural gas — is the one regional declaration that still triggers relief from all of parts 390–399, because Congress wrote it into statute. That's the mechanism behind the recurring Northeast winter heating-fuel declarations and their 30-day extensions, and it is materially broader than the gasoline-and-diesel waiver now in effect. They are different instruments with different terms. Don't reason from one to the other.

Also note what §390.23 relief depends on: direct assistance to the emergency relief effort. When the driver's direct assistance ends — including the empty return to the terminal, which the rule treats as part of it — the relief ends with it, and the driver goes back under normal HOS.

Intrastate operations: not automatic

The federal waiver governs interstate commerce. States may adopt the same relief for intrastate operations, but adoption is discretionary, not automatic. If your fuel runs are entirely inside one state, your authority to run 16 hours comes from your state agency's own adoption of the waiver — not from the FMCSA document. Check your state before assuming coverage, and check it per state if you operate in more than one.

The ELD problem nobody plans for

Here's the operational trap. The waiver relieves the driving limits; it does not reconfigure your ELD. Your ELD is still computing 11-hour, 14-hour, 30-minute-break, and 60/70-hour status against the standard rule set, which means a perfectly lawful 15-hour day under the waiver will generate ELD violation alerts — and those records are what an inspector reads at roadside.

What to do about it:

1. Annotate the records. Under §395.30(c)(2), every change or addition to an ELD record must carry an annotation. Have drivers annotate each shift run under the waiver with a short, consistent note naming the waiver and its date range. Consistency matters more than wording; a reviewer should see the same annotation on every affected day.
2. Ask your ELD provider what they support. Some platforms can flag a special driving category or suppress waiver-period alerts; some cannot. Find out before your first 16-hour day, not after.
3. Do not let drivers go off-ELD. A waiver from §395.3 is not an ELD exemption. Dropping to paper logs during the waiver period creates a §395.8 and ELD-rule violation on top of whatever prompted it.
4. Keep the waiver in the cab. Physical or digital, on every driver running under it.

What an inspector and your CSA profile will see

A roadside inspection during the waiver period follows the normal sequence: credentials, then the log. The inspector sees an ELD record showing 15 driving hours and has to decide whether that's a violation. Your driver's ability to produce the waiver and point to a clean annotation is the entire difference between a clean Level III and an HOS Compliance violation that lands in your Safety Measurement System profile the next time SMS recalculates. Our Roadcheck guide walks through what each inspection level covers.

If a violation is written against a driver who was legitimately operating under the waiver, that's exactly what DataQs is for — and the challenge is winnable when you have the annotated ELD record, the shipping papers showing gasoline or diesel, and proof your safety rating made you eligible. It is nearly unwinnable when you have none of those. Violations that stick push your HOS Compliance percentile up, and our guide to CSA score thresholds covers where that starts triggering interventions.

A checklist before you run a single 16-hour day

1. Confirm eligibility in writing. Current safety rating not Conditional or Unsatisfactory; no carrier-level out-of-service order. Save the screenshot with a date on it.
2. Screen every driver who will run under the waiver: valid CDL, required endorsements including hazmat, no disqualification or OOS order, Clearinghouse status not prohibited.
3. Distribute the waiver to every affected driver, physical or digital, and confirm receipt.
4. Write the operating rule down in one sentence your dispatchers can't misread: 16 driving hours maximum in any 24 hours, and 6 consecutive hours in the sleeper (or 8 off duty with no sleeper) inside every 24 hours.
5. Set the annotation standard and tell drivers exactly what to type.
6. Brief dispatch on §392.3. A driver who says they're too tired to run gets parked — and nobody gets pressured. A coercion complaint under §390.6 is a far worse outcome than a late load.
7. Verify hazmat paperwork is unchanged. Same shipping papers, same placarding, same loading and unloading procedures.
8. Calendar December 16. Put it in front of whoever builds schedules.

December 16 is a cliff, not a ramp

Because part 381 caps a waiver at three months, this one expires at 11:59 p.m. on December 16, 2026. At midnight, §395.3 applies again in full — 11-hour limit, 14-hour window, 30-minute break, 60/70-hour cap — including the weekly cap calculated across the preceding 7 or 8 days, which for a driver who spent that week running waiver hours may already be spent.

That is the single most likely way a fuel carrier gets hurt by this waiver: not during it, but in the first week after it, when a driver who was legal on December 16 is over the weekly limit on December 17. Plan the landing now.

One more thing: everything above is a summary written for planning purposes, and the controlling document is FMCSA's waiver itself. Read the actual text at fmcsa.dot.gov before you rely on any of it, and re-read it if FMCSA modifies the terms mid-period.

A waiver moves one rule. It doesn't move the other forty. MyCarrierVault tracks every §391.51 driver document, hazmat endorsement, medical certificate, and §396.17 vehicle inspection in your fleet — and emails you 30, 14, and 7 days before each one expires, so the paperwork that isn't waived never becomes the violation. Start a free trial and get your fuel operation documented before December 16.
