Several states have enacted modest state fuel tax increases this year. This continues a long-standing approach to transportation funding rather than introducing any sudden or sweeping changes. A recent review by Transport Topics shows that a handful of states implemented modest increases, while one moved in the opposite direction.
Why some state fuel taxes change automatically
Most of these changes weren’t driven by new legislation. Instead, they reflect automatic indexing formulas that allow fuel taxes to rise or fall based on inflation, construction costs, or fuel price trends. Many states adopted these approaches years ago to keep highway funding aligned with real-world expenses without requiring frequent legislative votes.
The changes vary by state and, in most cases, amount to routine annual adjustments rather than newly enacted increases.
What the changes mean for RV travel
For RVers, the impact is usually incremental. Even in states where taxes increased, the adjustment often comes down to a few cents per gallon, not a dramatic jump at the pump. Over the course of a long trip, that might mean a few extra dollars per fill-up. It’s noticeable, but rarely enough to affect travel decisions.
Diesel-powered motorhomes and tow vehicles may feel these adjustments slightly more, since diesel taxes are often higher to begin with. Still, overall fuel prices are shaped far more by crude oil markets, refining capacity, and seasonal demand than by state tax changes alone.
Fuel-tax dollars usually go back into maintaining the roads and bridges RVers use every day. In practical terms, smoother pavement and safer bridges matter far more on a long trip than a few cents’ difference in state tax rates.
The bottom line for RVers: Fuel taxes vary by state and tend to change gradually. If you already plan fuel stops with price differences in mind, nothing here calls for a new strategy—just an awareness that small regional variations are part of the normal landscape.
Fuel taxes tend to change gradually. For most RVers, good planning still matters far more than small differences measured in pennies.

Fortunately, the average price of both gas and diesel has been trending down in the last year, with the national average cost of gas down 11.4 cents in December 2025 from December 2024. Diesel national average cost is down 14 cents in January 2026 from January 2025. As an additional bonus for us in rural KY, our gas is 43 cents/gal below the national average, while diesel is 69 cents/gal below the national average. This is in spite of the 26 cents/gal tax on gas and 23 cents/gal diesel tax.
Except for Washington…..Bust out your 401K….Aaarg!
Thanks to President Trump’s abundant energy policies, we have the “drill baby, drill” mode. (Electric vehicles are a brainfart). Now if only the states would use ALL collected fuel taxes on fixing roads instead of diverting $$$ to non-road projects. Northern WI has been shorted by Madison politicians of cost-share road funds. Beautiful place to camp but roads wreck your vehicles getting there.
Anyhow, glad to see oil companies lowering prices so travel is more affordable.
People sure get excited about a few cents cheaper gas, yet the cost of everything else has nearly doubled.
Yes, obviously any genius can do the math, Eggs as an example have nearly doubled, going from $6.39/dozen to $3.27/dozen.
In fact, overall inflation has also nearly doubled this past year as any student of the Quality Learing Center can tell you…. it has gone from 6.7% to 2.6% which by my calculation is more like a double double doubling which equals a triple quadrupling. 🤣🤣🤣

Now if only California gas taxes would actually go to street and roadway repairs, we’d have smoother travels throughout the state..
All of our states. Bike lanes don’t do any R.V.’s any favors.
Public schools do a poor job of education. Oil is everywhere in the costs of items produced.
Food relies upon diesel farm equipment, is transported by diesel to processors, to packagers, to warehouse distribution centers, then hauled to supermarkets and restaurants.
Oil makes our clothing possible from raw materials, to factories, to the stores. And without diesel using farmers, you’d be hungry, be naked and be sober. (Joke, but also fact.)
Our RV manufacturing use petroleum for more than just tires Affordable energy is a blessing.
Contrary to the popular political spin, fuel taxes don’t make roads any better than a hotel room tax makes hotel rooms better. It’s just one more revenue stream into the government coffers.
We have bridges that have over a hundred years of tax collection but cannot be replaced because the money collected was not only spent but $38T beyond what was collected was spent as well.
There are overpasses you literally shouldn’t stop under due to concrete falling but hey, “it’s just a few cents more”…..
Don’t count on gas being low. In three years or so when another party takes over as president. Everything that uses oil will be going up. With the price of fuel up. You don’t see shipping prices coming down.
The chart in the article is misleading. Texas didn’t raise it’s gas tax.It’s only 4 states.
From the article linked:
“The states of Michigan, New Jersey, Minnesota and Florida adopted fuel-tax increases for 2026, while just one state — Utah — reduced its motor fuel tax rates.
All of the changes took effect Jan. 1.”
I was going to comment the same, 4 states went up. but overall fuel prices went down. And taxes are fixed cost not based on the prince of fuel.
All that additional road-tax money and they will still be full of potholes you could hide a Sherman Tank in. Government efficiency at it’s best!
