Vehicle miles traveled tax

A vehicle miles traveled tax, also frequently referred to as a VMT tax, VMT fee, mileage-based fee, or road user charge, is a policy of charging motorists based on how many miles they have traveled. It has been proposed in various states in the United States including Illinois who are currently following through with implementing this tax, and elsewhere as an infrastructure funding mechanism to replace, or supplement the fuel tax, which has been generating billions less in revenue each year due to increasingly fuel efficient vehicles.
