SCR 1004 Arizona Senate · 57th Legislature - First Regular Session

prohibit tax; monitoring; vehicle mileage

This constitutional amendment (SCR 1004) prohibits Arizona state and local governments from imposing taxes or fees based on vehicle miles driven, or enacting rules to monitor or limit miles traveled without a person's voluntary consent. It specifically bans policies like mileage-based road usage fees while allowing exceptions for interstate commercial vehicle fuel tax agreements and vehicles owned by government entities. If approved by voters, it would amend Arizona's constitution to block these measures. The bill passed both legislative chambers in 2025 and will now be submitted to voters for approval.
