Dealing with the Decline in Gas Tax Revenues Due to the Decline in Driving
The Department of Transportion announced today that we drove 9.6 billion fewer vehicle-miles traveled (VMT) in May 2008 compared to May 2007. While that is good for reducing carbon emissions, it is bad for the Highway Trust Fund. When we use less gasoline, less gasoline excise taxes are collected.
According to Transportation Secretary Mary E. Peters: "By driving less and using more fuel-efficient vehicles, Americans are showing us that the highways of tomorrow cannot be supported solely by the federal gas tax."
Our current federal gasoline excise tax is 18.4 cents per gallon. It is not adjusted for inflation. It has been known for some time that adjustments would eventually need to be made in the rate or HTF funding approach as MPG of cars increased. Various studies have been done to get an idea of the problem and possible solutions to provide more funds for the HTF to maintain and build roads.
