NEW YORK (CNNMoney.com) -- Gasoline prices rose overnight to set another record high, a AAA survey showed Thursday.
The average price of regular unleaded rose two-tenths of a cent to a national average of $3.289 a gallon, exceeding the previous record set Monday, according to AAA's Web site.
Regular cost $3.168 a gallon on average at this time last month and $2.70 a year ago.
Pump prices have been on a record-setting run as the price of crude oil has held above $100 a barrel.
The average price-per-gallon of diesel fuel fell two-tenths of a cent to $4.023.
Diesel averaged $3.681 a gallon last month and $2.865 a year ago.
The high price of diesel fuel has been a major concern for workers in the trucking industry. Trucking companies, and especially independent truckers, are increasingly faced with high fuel costs that can drive them out of business.
