With each gallon of gasoline pumped in the United States since 1932, drivers have been paying taxes. The revenue is used for road repairs and public transportation such as train and bus systems.
Currently, the federal government takes 18.4 cents per gallon for gas or 24.4 cents per gallon for diesel. State gas taxes range from a national high of 61 cents per gallon for gas in Pennsylvania, to a low of 8.95 cents per gallon in Alaska.
