Fuel prices have an enormous effect on almost every aspect of our lives. Increases in diesel prices are reflected in the cost of every good that is delivered. Price jumps alter our daily spending habits by chipping away at expendable income and even make the cost of taking a vacation unreachable for some. There’s no way around it, we all suffer from increases at the pump.
This is especially true for those in the trucking industry. The average trucker travels over 100,000 miles per year. Considering modern trucks average 6.5 miles per gallon, each truck will consume over 15,000 gallons of diesel every year! At those quantities, every cent matters.
This post is updated weekly for you to track which states and regions have the cheapest fuel prices.
