AAA Oklahoma says gas prices are the lowest in more than a decade as the summer driving season kicks off.
Pump prices across Oklahoma have risen about 18 cents a gallon in the past three weeks, and Tuesday's average price for regular gasoline was $2.13. But AAA says it's still 33 cents below the average one year ago and 19 cents below Tuesday's national average of $2.32.
The nation's top five least expensive markets for gasoline are Mississippi and Texas at $2.09, South Carolina at $2.10 and Arkansas and Louisiana at $2.11. The most expensive is California at $2.81.
The national gas price average for the month of May was $2.25 per gallon, 44 cents per gallon less than a year ago and the cheapest for the month since 2005.
