Arizona Proposition 141: Ban taxes and tracking based on miles driven
What it does. Proposition 141 would add a section to the Arizona Constitution barring the state and any county, city, town or other local government from imposing a tax or fee based on the number of miles a person travels in a motor vehicle. It would also bar them from monitoring or limiting the miles a person travels unless the person voluntarily consents. It would not apply to commercial vehicles that operate in more than one state under an interstate agreement for reporting fuel taxes or registration fees, or to vehicles owned and operated by the state or local governments. [1]
Official ballot question. Proposed amendment to the Constitution by the Legislature relating to taxation. Amending Article IX, Constitution of Arizona, by adding Section 26. Prohibits taxes or fees based on vehicle miles traveled and laws monitoring or limiting vehicle miles traveled without consent. [1]
If you vote yes
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. [1]
If you vote no
A “no” vote shall have the effect of maintaining the current constitutional language related to taxation. [1]
What it would cost
Arizona law requires the Joint Legislative Budget Committee (JLBC) staff to summarize the fiscal impact of each voter initiative, and the JLBC states that “This requirement excludes legislatively referred propositions.” This measure was referred by the legislature, so the official pamphlet has no JLBC fiscal summary for it. The Legislative Council analysis in the pamphlet does not include a cost estimate, and we did not find another official one. [2] [1]
Both sides
Strongest case for
In an argument sponsored by the Arizona Free Enterprise Club, Hans VanDanElzen of Gilbert writes that “Vehicle mileage tracking is surveillance, plain and simple,” and that Arizona “can find ways to ensure electric vehicles contribute their fair share to road maintenance without building an invasive tracking infrastructure. Tax the tires. Tax charging stations.” [1]
Gregory Gonzalez of Mesa writes that “A mileage tax isn’t about funding roads. It’s about collecting granular data on where you drive, when you drive, and how often,” and that the amendment “keeps government out of our daily movements.” [1]
Richard Martin of Tucson writes that “A per-mile tax punishes the people who can least afford it,” including rural families, commuters and tradespeople, and that it “raises the cost of every product on every shelf, because every one of them got there by truck.” [1]
Strongest case against
Ted Maxwell, chair of the Arizona State Transportation Board, writes that the measure “would permanently prohibit consideration of vehicle-miles-traveled (VMT) funding options, even voluntary or pilot programs designed to evaluate whether such approaches could work for Arizona.” [1]
Traffic engineer Michael Grandy writes that the state’s long-range transportation plan identifies $231.4 billion in needs over 25 years against $69.1 billion in forecast revenue from the fuel tax, “a funding gap of $162.3 billion.” He says a mileage-based fee would more equitably assess vehicles for their proportional wear and tear on roads, and that it is “short-sided and premature to prohibit it before even conducting analysis.” [1]
Civic Engagement Beyond Voting says the measure would keep plug-in electric vehicles, which “don’t pay gas taxes,” from ever paying by the mile: “Anyone who drives a gas-fueled vehicle pays 18 cents in tax on every gallon of gas,” while Arizona’s gas tax “hasn’t gone up in decades.” [1]
What neither side is saying
Context that bears on what this measure does or who it affects but that the arguments above do not address. These are sourced facts, not arguments for or against the measure.
- The consent exception covers monitoring, not charging. In the Legislative Council’s description, the ban on monitoring or limiting miles applies “unless the person voluntarily consents.” The ban on imposing a tax or fee based on miles traveled has no consent exception, so a voluntary per-mile fee program would also be barred.
