Vehicle miles traveled: local tax and state fund prohibition.

CA AB1783 is a proposed law that aims to prevent local governments from imposing taxes based on the number of miles vehicles travel. It also seeks to stop the state from creating funds that would rely on vehicle miles traveled as a tax measure. The bill is intended to protect drivers from additional financial burdens related to their travel habits.

CA AB1783 is a house bill in the California 2025-2026 Regular Session, sponsored by Carl DeMaio (R), currently “Failed” since May 12, 2026.

Supporters of CA AB1783 argue that the bill will safeguard taxpayers from unnecessary taxes and fees associated with vehicle usage. They believe it promotes personal freedom by ensuring that individuals are not penalized for driving, which is a fundamental part of daily life in California. This legislation is seen as a step towards protecting the rights of consumers and maintaining economic stability.

Critics of CA AB1783 contend that the bill undermines efforts to address traffic congestion and environmental issues caused by vehicle emissions. They argue that without the ability to tax vehicle miles traveled, local governments will struggle to fund necessary infrastructure improvements and public transportation options. This could lead to increased traffic and pollution, ultimately harming California's long-term sustainability goals.
