California currently funds our transportation system through the gas tax, but as we look toward a future with a growing amount of fuel-efficient and alternative fuel vehicles, the state needs to find a different revenue mechanism.

California is researching a road charge as a potential replacement to the gas tax. A road charge is a per mile tax where drivers pay to maintain the roads based on the number of miles they drive instead of the fuel they use.
