AAA Oklahoma says the state's average price for a gallon of regular unleaded gasoline is up to $3.48 per gallon, the highest price since September 2013.
The automobile travel organization reported Tuesday the statewide average price jumped nearly 3 cents overnight, with some cities, including Tulsa, seeing even steeper climbs.
AAA cited the ongoing conflict in Iraq as a driving factor in the price hike.
Oklahoma's average price is still nearly 20 cents lower than the national average of $3.66 per gallon. Oklahoma had the ninth lowest average price on Tuesday, with the lowest average in Mississippi and South Carolina at $3.39 per gallon.
Drivers in Hawaii ($4.35) and California ($4.10) reported paying the highest average price.
