Proposition 141
Prohibit Taxes and Fees on Vehicle Miles Traveled and Monitoring Amendment
On the ballot
Arizona · November 2026 general election · Legislative referral · Election day November 3, 2026
Topics: Taxes and revenue, Transportation
In plain language
Proposition 141 would amend the Arizona Constitution to bar state and local governments from taxing or charging a fee based on the number of miles a vehicle travels, and from limiting or monitoring an individual's vehicle miles traveled without the owner's consent. It would not restrict a mileage-based program for commercial vehicles crossing state lines, or a mileage tax or limit that applies only to a government-owned vehicle. The Legislature referred it in 2025 as Senate Concurrent Resolution 1004, ahead of any state proposal to replace shrinking fuel-tax revenue with a mileage-based fee.

What supporters and opponents say
These are summaries of arguments made by the named organizations, drawn from the sources listed below. They are their claims, not this site's, and this site takes no position on the measure.
What supporters say
- Scot Mussi, president of the Arizona Free Enterprise Club, supports the amendment because his organization opposes vehicle-miles-traveled programs.
- Supporters say a constitutional ban is needed to head off any future mileage tax being discussed as a replacement for declining fuel-tax revenue.
What opponents say
- State Sen. Priya Sundareshan asked how the state would fund and repair highways without that kind of revenue and called it premature to prohibit a mileage program before gathering information about vehicle-miles data.
- Opponents note that electric vehicles do not pay the state's 18-cent-per-gallon gasoline tax that funds the Highway User Revenue Fund, and argue that a shift toward electric vehicles could erode the state's ability to build and repair roads without some alternative funding mechanism.
