Fuel prices touch fresh record
Regular unleaded gasoline and diesel reach fresh all-time highs.
NEW YORK (CNNMoney.com) -- Prices at the pump hit a new record overnight, a daily survey from auto group AAA revealed Monday.
The average price of regular unleaded gas rose to an all-time high of $4.109 a gallon, up half a cent from the previous day.
Gas prices have surged roughly 40% in the past year, according to AAA.
The price of diesel, which is used to power most trucks and commercial vehicles, rose nearly a penny to a record $4.824 a gallon.
Drivers in Alaska were hit with the highest gas prices at $4.634 a gallon. California comes in second at $4.514. Those two are the only states where prices top $4.50, though Hawaii is just pennies away at $4.474.
Hawaii also leads the nation in diesel prices at $5.359 a gallon. Diesel is also selling for more than $5 in four other states: Alaska, California, Connecticut and New York.
Missouri has the cheapest prices for regular unleaded at $3.92 a gallon, while Montana has the cheapest diesel at $4.606.
A separate survey released on Sunday found that the average price of gasoline jumped more than penny over the past three weeks - the smallest price hike this year. That survey showed that the average price was a fraction of a cent above $4.11 a gallon, said publisher Trilby Lundberg.
