5 States With the Most Expensive Gas in the US

3. Washington

Price of Gas per Gallon: $4.619

Washington has one of the highest gas taxes in the country at 49.4 cents per gallon. Those taxes are how the state has funded many recent highway projects.

Washington lawmakers embarked in early 2012 to learn if charging drivers for the miles they travel could eventually replace taxing them on every gallon of fuel they buy. The concern then, and now, is that gas tax receipts are in a slow decline as passenger cars get more fuel efficient and electric vehicles become more prevalent.
