Arizona ballot measure · November 3, 2026

Arizona Proposition 141, explained

Ban on vehicle mileage taxes and tracking. A ballot measure is a yes-or-no question put directly to voters — no candidate is involved, and the wording on the ballot is the wording that becomes law. This page shows that wording first, then what it actually changes.

The official wording

PROHIBITS TAXES OR FEES BASED ON VEHICLE MILES TRAVELED AND LAWS MONITORING OR LIMITING VEHICLE MILES TRAVELED WITHOUT CONSENT. A "yes" vote shall have the effect of amending the Arizona Constitution to prohibit: (1) taxes or fees based on motor vehicle miles traveled; and (2) laws or rules that monitor or limit motor vehicle miles traveled without consent. These prohibitions do not apply in certain instances to interstate commercial vehicles or to vehicles owned by the state or local governments. A "no" vote shall have the effect of maintaining the current constitutional language related to taxation.

This is what appears on the ballot. Everything below explains it.

What it actually means

Amends the Arizona Constitution so the state and local governments can never tax or charge fees based on how many miles a person drives, or monitor or limit miles driven without the person's consent. Interstate commercial vehicles under existing fuel-tax agreements and government-owned vehicles are excepted.

If you vote YES

The state, counties, cities and other local governments could not impose any tax or fee based on vehicle miles traveled.
Governments could not monitor or limit how many miles a person drives unless the person voluntarily consents.
The ban would not apply to interstate commercial vehicles covered by fuel tax or registration agreements, or to vehicles owned and operated by governments.
Because it is constitutional, only another statewide vote could undo it.

If you vote NO

Arizona would continue to fund most road work through a per-gallon fuel tax, and the Constitution would not rule out a mileage-based tax or fee.
Any future mileage tax or tracking program would still need legislation or voter approval under existing rules.

The numbers that matter

Vote needed: Simple majority
Fiscal estimate: None published

Why supporters say YES

States across the country are building systems to tax drivers by the mile, which requires tracking every drive; the amendment would make Arizona the first state to permanently bar government from tracking, taxing or limiting the miles people drive.
— Official argument for, by Scot Mussi, President, Arizona Free Enterprise Club
Mileage tracking is surveillance; electric vehicles can be made to contribute to road costs through other means, such as taxes on tires or charging stations, without tracking travel.
— Official argument for, by Hans VanDanElzen of Gilbert (sponsored by the Arizona Free Enterprise Club)

Why opponents say NO

Fuel tax revenue is eroding as vehicles become more efficient and electric, and the state faces an estimated $68 billion in unmet transportation needs; a mileage fee is one option that would reflect actual road use, and rural drivers now subsidize urban roads.
— Official argument against, by Tom Prezelski, Senior Policy Advisor, Rural Arizona Action
Arizona's long-range transportation plan projects a $162 billion funding gap over 25 years; the state needs more funding options, not fewer, and should not ban one before studying it.
— Official argument against, by Michael Grandy, traffic engineer, Gilbert

What’s genuinely uncertain

Arizona has no mileage tax or tracking program today, so the measure's immediate practical effect is limited; its significance is in ruling out an option for future road funding.
Transportation funding gap figures come from opponents citing state plans, not from an official fiscal analysis of this measure.

The bottom line

A permanent guarantee against mileage taxes and travel tracking, against removing a possible future way to pay for roads as fuel tax revenue declines.

One neutral sentence describing the tradeoff — not a recommendation.

Checking it against the official text

The Arizona Secretary of State publishes the certified measures and, in most states, an official voter guide with fiscal notes. That is the authoritative version. Everything here is an explanation of it, not a substitute for it.
