Gas prices

Out of refining costs, retail markup, and transportation costs, federal and state taxes are the strongest determiner for how much consumers pay for gas. These taxes are generally invested back into the construction and repair of road infrastructure. The federal government also places a tax on gasoline sold in the United States but almost every gasoline tax imposed by the states themselves is higher than this federal rate. Higher gasoline taxes may also affect driving habits, as those who live in states with higher gas taxes tend to drive less when other options are available.
