The constitutional amendment would prohibit the state and local governments from doing two things. First, they would not be able to impose a tax or fee based on the number of miles an individual travels in a motor vehicle, also known as a vehicle miles traveled tax. Second, state or local governments would be unable to create a law that limits or monitors the number of miles traveled in a motor vehicle.

The amendment would not restrict the government's ability to create such a tax or limitation for motor vehicles owned and operated by the state or local government. Additionally, 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.

Currently, Arizona does not tax or monitor vehicle miles traveled. The amendment would only prohibit the government from creating any tax or monitoring program in the future.
