Should states be prohibited from using mileage-based taxes to fund road projects?
Proposition 141 will appear on the 2026 statewide ballot to decide if the state should constitutionally ban taxes or fees based on miles driven. If approved by voters on November 3, 2026, the measure would prevent government entities from implementing mileage-based taxation or tracking driving distance.
Why it matters
The measure addresses concerns over government privacy while responding to revenue shortfalls for road projects caused by the rise of fuel-efficient and electric vehicles. Legislators are seeking to define the future of transportation funding as traditional gas tax revenue declines.
Road project revenue in Arizona is currently supported by an 18-cent per gallon gas tax. Across the country, 37 states have already explored or implemented vehicle miles traveled tax programs.
The players
Arizona
The state is the location where voters will decide on the constitutionality of mileage-based vehicle taxation.
The details
Proposition 141 prohibits any state or local government entity from tracking or limiting driving distances without explicit consent from the driver. This legislative referral directly counters proposals to shift away from gasoline taxes toward usage-based fees for road funding.
Timeline

November 3, 2026: The date of the general election when voters will cast their ballots.
Roadmap
This proposal reflects the tension between maintaining traditional transportation funding and the rapid shift toward electric vehicles. By preemptively banning mileage taxes, Arizona is taking a definitive stance in the national debate over how to finance road infrastructure as gasoline consumption wanes.
If passed, the measure will protect drivers from future government tracking related to distance-based fees or taxes. Residents should prepare for potential legislative discussions on alternative funding methods for road maintenance should gas tax revenue continue to decrease.
The takeaway
Voters are being asked to decide whether privacy protections should supersede the need for new road funding mechanisms. Citizens should familiarize themselves with the language of Proposition 141 to understand how it could impact future infrastructure budgets in the state.
