The average price for a gallon of regular gas was $3.52 in Monday's survey from auto club AAA, the Oil Price Information Service and Wright Express. That's 7 cents higher than a week ago and is the third week in a row that prices at the pump are up.
Ohio pump prices are up 27 cents from this time last month. Last year at this time, drivers were paying $3.14 a gallon.
Nationally, the average cost was about $3.42 per gallon on Monday.
Experts say instability in the Middle East is leading to higher oil prices.
