The resolution HCR2018 proposes an amendment to the Arizona Constitution that would prohibit the state and any local government from imposing taxes or fees based on the vehicle miles traveled by individuals in motor vehicles. Additionally, it seeks to prevent any rules or laws that would monitor or limit vehicle miles traveled unless such measures require voluntary consent from the individual. This amendment is subject to voter approval and aims to protect citizens from potential mileage-based taxation and monitoring.

Furthermore, the resolution clarifies that these prohibitions do not apply to interstate agreements related to the administration of fuel taxes or registration fees for commercial vehicles operating across state lines. If approved, the Secretary of State is tasked with submitting this proposition to voters during the next general election, ensuring that the decision remains in the hands of the public.
