Should Arizona be allowed to tax drivers based on how many miles they drive?

Early results from Arizona's November 3, 2026 election show voters trailing on Proposition 141, a measure that would bar the state from taxing or tracking drivers by miles driven. Early returns show 51% of the vote against it, and ballot measures need a simple majority of yes votes to pass.

Why it matters

Arizona drivers currently pay a gas tax that helps fund road and freeway maintenance, but those revenues are declining as more drivers switch to electric vehicles. A mileage-based tax is one proposed alternative, so Proposition 141 would close that option off for the state.

Proposition 141 would prohibit Arizona from imposing taxes or fees based on miles driven and would ban the state from adopting rules to track or limit miles driven. Early results show 51% of votes cast against the measure.

The details

Proposition 141 is a ballot measure that voters decide directly, and ballot measures in Arizona need a simple majority of yes votes to become law. A mileage-based tax charges drivers according to how far they travel rather than how much fuel they buy, which is one proposed replacement for the gas tax. The measure would also forbid the state from adopting any rules that track or limit miles driven.

The Home Front

Gas tax revenue has been falling as more Arizona drivers opt for electric vehicles, which puts pressure on the funding that pays for road and freeway maintenance. Proposition 141 would remove mileage-based taxation as a possible way to replace that revenue.

If you drive in Arizona, the outcome of Proposition 141 will determine whether a mileage-based tax can be considered as a replacement for the gas tax in the future. Check the official Arizona Secretary of State election results for final certified numbers once counting is complete.

The takeaway

Ballot measures in Arizona pass on a simple majority, so the final certified count will decide whether Proposition 141 becomes law. Drivers who own electric vehicles should keep an eye on how state transportation funding is restructured as gas tax revenue continues to decline.
