Because of vehicles with higher fuel efficiency, slightly less driving, and the gas tax not being changed since 1993, the motor vehicle fuel tax, or “gas tax”, has failed to pay for everything that Congress has legislated that it should pay for. The Highway Trust Fund, which includes the Mass Transit Account, has received several infusions of money from the “general revenue fund” – to the tune of over $60 billion.

But a new report from the Government Accountability Office, the congressional think tank focused on financing, past, present, and future, has made the country take a giant step forward in considering a switch to a fee that more accurately charges usage. The report, like all GAO studies, was commissioned by the House Transportation Appropriations Subcommittee*.

The gas tax charges drivers based on their use of petroleum, different vehicles can go different distances on the same amount of petroleum: essentially, some pay less than others for the same use of the road. Addiitionally, the counts of how much people drive has decreased (called vehicle miles traveled, or VMT), yet our demand for funds to maintain and build new infrastructure outpaces the incoming revenues from the gas tax. Lastly, the federal gas tax hasn’t changed at all, sticking to a cool 18.4 cents per gallon (for non-diesel drivers) since 1993. “While the gas tax was equal to 17 percent of the cost of a gallon of gas when it was set at its current level in 1993, it is now only 5 percent” (Streetsblog).
