NEW YORK (CNNMoney) -- Gas prices rose Tuesday for the 14th straight day, with drivers in some parts of the United States now paying more than $3.90 a gallon.
The national average price for a gallon of regular gasoline is now $3.517, according to a daily survey by motorist group AAA. That's up eight tenths of a cent from $3.509 on Monday.
Gas prices have risen nearly 15 cents so far this month. That's on top of a nearly 27 cent increase in February.
California continues to have the highest gas prices in the nation, with drivers there paying an average of $3.908 a gallon. Hawaii had the second highest average price at $3.89 a gallon, while Alaska came in third at $3.845 a gallon.
The lowest gas prices are in Wyoming, where gas averages $3.197 a gallon. Montana and Missouri also have relatively low gas prices.
Gas prices have been driven higher by an increase in the price of crude oil, the main ingredient in gasoline.
Oil prices have risen more than 10% so far this month, as investors remain nervous about the crisis in Libya. However, prices were trending lower Tuesday following reports that other oil-exporting nations in the region are considering boosting output.
