TRENTON, N.J. (AP) — Drivers are seeing slightly higher prices at the pumps in New Jersey.

AAA Mid-Atlantic says the average price of a gallon of regular gas in the state on Friday was $2.30. That's up a penny from last week.

Motorists were paying $2.09 for gas at this time last year. A 23-cents-per-gallon gas tax increase went into effect Nov. 1.

The national average gas price on Friday was $2.26, flat from the week before. A year ago motorists were paying $2.22.

AAA says the pump price increases are due to increased demand stemming lower prices than usual for the summer.

The organization also says gas prices are among cheapest levels seen this year but that could change, especially if there is a major hurricane in the Gulf of Mexico.
