Gas prices match record high
Nationwide average price of regular unleaded back at all-time high of $3.287 a gallon, AAA survey shows.
NEW YORK (CNNMoney.com) -- Average gasoline prices are back at their record high, a key survey conducted for the motorist group AAA showed Wednesday.
The nationwide average price of regular rose a tenth of a cent to $3.287 a gallon, matching the record high reported on Monday, according to AAA's Web site.
Regular was $3.165 a gallon on average at this time last month and $2.696 a gallon a year ago, according to AAA.
The average price-per-gallon of diesel fuel rose slightly to $4.025 a gallon. Diesel was at $3.674 last month and $2.855 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.
Hawaii continued to lead the country in average gas prices, with drivers paying around $3.66 per gallon. Gas prices in California were also above $3.60.
Prices hit $3.046 in New Jersey, which remained the only state where gas prices stayed below $3.10 a gallon.
The AAA survey, updated daily, tracks prices at roughly 80,000 service stations across the country. It is conducted for the group by Oil Price Information Service.
