Diesel Hit A Record And The Fuel In Your Tanks Is Not Cargo

Diesel set an all time record on Friday

The national average price of diesel reached $5.85 a gallon on Friday September 4 2026, the highest figure ever recorded, according to AAA data reported by Transport Topics and Land Line. It passed the record set in June 2022. A week before it was $5.61. A month before it was $5.37. A year ago it was $3.71, so the pump is more than two dollars a gallon higher than it was last September.

The pressure has not eased since. Transport Topics reported on Monday September 8 that Brent crude reached $98.48 a barrel, up 1.5 percent and its highest level in roughly six weeks, with West Texas Intermediate at $93.79. The move followed a wave of Houthi attacks on oil facilities in southern Saudi Arabia on top of the six month conflict between the United States and Iran. The Energy Information Administration still projects diesel back near $4.86 a gallon by the end of the year, with its next short term outlook due September 9. One caveat worth keeping, the Associated Press notes the June 2022 record works out to about $6.56 in today's dollars, so this record is nominal rather than a new worst ever in real terms.

What is sitting in your tanks and which policy it falls under

Here is the part most owner-operators have never had a reason to think about. The diesel you just paid for is your own property. It is not cargo. A motor truck cargo policy covers the freight you accepted from a shipper or a broker, so the load on the trailer is covered and the fuel in the saddle tanks is not. That distinction did not matter much when a fill ran a few hundred dollars. At $5.85 a gallon, a pair of 150 gallon tanks topped off is holding roughly $1,755 of your money, and that money sits in the truck every night it is parked.

If someone cuts a fuel line or breaks a filler neck to get at it, the damage to the truck itself is a physical damage question. Whether the diesel that left with them is covered depends on your specific form, because policies do not all treat fluids and property carried in the vehicle the same way. Read yours instead of assuming, and ask your agent to put the answer in writing now rather than after a loss.

Your deductible is what actually decides this one

Run the arithmetic before you go shopping for a fix. A full fill at today's price is under two thousand dollars, and most small fleets carry a physical damage deductible high enough that a single stolen fill lands entirely inside it, so on a lot of policies there is no claim to file at all. That is not a hole in your coverage, that is how the coverage was priced. The useful response is not a policy change. It is locking caps, parking where the truck is lit and visible, and treating a fresh fill the way you would treat that much cash on the seat.

Fuel card fraud is a different fight entirely

The other loss that shows up when diesel is expensive is a card, not a tank. A skimmed or shared fuel card can move thousands of dollars in a weekend, and a standard trucking policy is usually not where that gets resolved. Card fraud runs through the issuer under the terms of your card agreement, and those agreements work on short dispute windows. Crime and employee dishonesty coverage exists, but it is a separate purchase rather than something folded into commercial auto. Find your card's dispute deadline before you need it, switch on whatever transaction controls the issuer offers, and read the statement weekly instead of monthly while prices sit here.

The expensive mistake to avoid while the fuel bill is this big

Fuel is paid at the pump and freight pays in thirty days, so a move this size widens the gap between money going out and money coming in. Large shippers pass the cost along, and the Associated Press notes Amazon added a 3.5 percent fuel and logistics surcharge in April 2026. A single truck on the spot market often cannot. When the squeeze hits, the two bills that get pushed back are the premium installment and the filing, and that is where a cash problem turns into an authority problem. A lapsed federal filing is not simply a gap in protection, it puts your operating authority at risk, and commercial auto liability is the filing the FMCSA actually watches. If the payment is the problem, tell your agent before the due date rather than after. There is almost always more room in how a policy is built than in whether you carry one, and our breakdown of what commercial truck insurance costs shows what really drives the number.
