This November, Arizona voters will decide whether to amend the state Constitution to prohibit taxes on vehicle miles traveled (VMT) and restrict government monitoring of or limits on how much people drive through Proposition 141.
The proposal would bar the state, counties, cities, towns, and other political subdivisions from imposing a tax or fee based on the miles a person travels in a motor vehicle. It would also prohibit those governments from enacting mileage-monitoring or mileage-limiting laws or rules unless they require the person’s voluntary consent.
The measure reached the ballot through SCR 1004, which passed the Senate on Feb. 20, 2025, and the House on June 13, 2025. The resolution was filed with the Secretary of State on June 16, 2025.
The Legislature advanced the proposal amid debate over mileage-based charges as a source of transportation funding. Such charges assess motorists based on distance traveled.
Supporters describe Proposition 141 as the Freedom to Move Act. In a published ballot argument, Arizona Free Enterprise Club (AZFEC) President Scot Mussi urged approval for the sake of privacy, affordability, and freedom of travel.
“From wide-open highways cutting through desert landscapes, lanes carving through mountains, bridges traversing valleys and open water, the Freedom to Move is engrained in the American spirit,” Mussi wrote. “Vote YES to preserve your privacy. Vote YES to keep Arizona affordable. Vote YES to preserve your freedom to move,”
In an August interview with Mussi, AZFEC Vice President Aimee Yentes noted that Arizona’s transportation dollars already come from several taxes, such as the tax on fuel and sales taxes. She added, “…this would prohibit the government from tapping into a new way to tax your driving by taxing every mile that you drive…”
Arizona Trucking Association President and CEO Tony Bradley also submitted an argument supporting the measure, citing reporting, auditing, and administrative costs associated with mileage-based taxation.
“Unlike fuel taxes, which are collected efficiently at the point of sale, mileage-based taxes require ongoing reporting, oversight, and enforcement,” he wrote. “Government agencies must devote resources to audits and compliance, while taxpayers and businesses bear additional recordkeeping and reporting costs. Those dollars are spent operating the tax system instead of improving roads and bridges.”
Under the official ballot explanation, a “yes” vote would amend 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.
A “no” vote would retain the current constitutional language on taxation.
If Proposition 141 is approved by voters, Arizona would become the first state to embed a ban on VMT taxes and mileage limits into its constitution.
