As the U.S. heads into peak camping season, gasoline and diesel prices are ratcheting up even higher than the end-of-school-year excitement.

If a road trip is in your summer vacation plans, here are the states where you’ll find the lowest—and highest—prices at the gas pump.

Why Gas Prices Differ From State To State

Seasoned roadtrippers know that gas prices can vary wildly from state to state. But why? The two main factors that influence price differences at the pump are the location’s proximity to refineries, ports, and pipelines, and state taxes. 

The further you are from a gas supply, the higher your cost at the pump will be, according to the U.S. Energy Information Administration. In regions that have relatively few refineries and pipelines, like the western U.S., fuel transportation costs are greater. And that extra cost is passed onto the consumer. 

The second biggest reason that gas prices vary is because of individual state taxes. Federal taxes are 18.4 cents per gallon of gasoline and 24.4 cents per gallon of diesel. Every state adds its own fuel tax to that, but each state is different. Missouri, for example, adds 19.5 cents per gallon, while Pennsylvania adds 57.6 cents per gallon.

These two factors, plus other contributing elements, like gas station competition and operating costs, result in varying gas prices throughout the country, regardless of whether crude oil is selling at a low or high cost per barrel.
