SAN JOSE, Calif., July 18 (UPI) -- A California transportation agency said it is considering a tax on motorists for each mile they drive in their cars.

The Metropolitan Transportation Commission, the San Francisco Bay area agency leading the discussions on the possible tax, said the plan would likely involve GPS-like devices installed in cars to keep track of the miles traveled by motorists, with low-income drivers excepted, the San Jose Mercury News reported Wednesday.


Randy Rentschler, a spokesman for the Metropolitan Transportation Commission, said the plan for a vehicle miles traveled tax, or VMT, could take up to a decade to implement if it is embraced by the public.

"I don't want to say it's pie in the sky. A VMT charge is really an option for the future to be looked at and considered," Rentschler said.

The Association of Bay Area Governments, which includes city councilors and county supervisors, is scheduled to analyze a study of the proposal Thursday.
