NEW YORK (CNNMoney.com) -- Retail gas prices hit record highs for the 22nd day in a row, motorist group AAA's Web site showed Thursday.
The nationwide average for a gallon of regular unleaded rose eight-tenths of a cent to $3.952, marking the 23rd straight day that gas prices have increased.
The AAA survey shows gas prices are up nearly 10% from a month ago and almost 24% higher from year-ago levels.
The average price for gas has passed the $4 a gallon mark in 11 states, as well as in Washington, D.C.
The most expensive state for buying gas is Connecticut, where a gallon of regular unleaded costs on average $4.223, according to AAA. The second most expensive state is Alaska, where a gallon of gas costs $4.209.
The least expensive state for purchasing gas is Missouri, where a gallon costs $3.761 on average. The second least expensive state for gas is Wyoming, where a gallon runs $3.783 a gallon.
Gas prices have been pushed higher by the rising price of crude oil, which has more than doubled in price in the past year.
