Prohibit Taxes or Fees on Miles Traveled in Motor Vehicle Amendment
Transportation Taxes & Vehicle Regulations
Summarized
What Would This Do?
Proposition 141 would prohibit state and local governments from doing two things. First, they could not impose a tax or fee based on the number of miles an individual travels in a motor vehicle — a "vehicle miles traveled" (VMT) tax. Second, state or local governments could not create a law that limits or monitors the number of miles traveled in a motor vehicle.
The prohibition would not apply to motor vehicles owned and operated by state or local government, and it would not limit the state's ability to participate in or create such programs for commercial vehicles that operate in more than one state.
As of 2026, Arizona does not tax or monitor vehicle miles traveled. Proposition 141 would only prohibit the government from creating any such tax or monitoring program in the future.
A “Yes” Vote
A "yes" vote supports this constitutional amendment, which would prohibit the state and local governments from implementing any tax or fee based on vehicle miles traveled, and from enacting any rule or law to monitor or limit vehicle miles traveled without the person's consent.
A “No” Vote
A "no" vote opposes this constitutional amendment, thus maintaining the legislature's ability to implement taxes or fees based on vehicle miles traveled and to enact rules to monitor or limit vehicle miles traveled without the person's consent.

“As we have seen in other states, governments left to their own devices will succumb to radical attempts to track, tax, or limit their citizens' transportation miles. These environmental schemes have no place in a free and prosperous society.”
“This at its core says that the government shall not tax or track you for the miles that you drive. We all know that there is a push within the radical environmentalist fringe that wants to eliminate the internal combustion engine. They want to make sure that you can't have freedom of mobility to go where you please, when you please, and how you please.”

“How do we fund our highways? How do we repair roads without that kind of revenue, without that kind of information? It's premature to be prohibiting things ... without even finding out information about vehicle mileage.”
“[Prop. 141] really is hurting our opportunities in the future to address what is becoming a very critical shortfall for state and local infrastructure funding.”
