Gas prices will drop to a national average of between $3.20 and $3.40 for the summer driving months, according to AAA.
Regular gas averaged $3.55 per gallon nationally in April--a three-year low for the month. That cost represents a roughly 13-cent decrease from March.
On Tuesday, gas averaged $3.51 across the country. One year earlier, on April 30, 2012, a gallon of gas cost $3.82.
Low oil costs and ample refinery production are expected to continue to drive down the cost of gas in the coming months, according to Jenny M. Robinson, AAA Mid-Atlantic's manager of public and government affairs.
“Gas prices in much of the country have declined this spring because of lower oil costs, ample refinery production and continued weak demand,” Robinson said. “Gas prices have fallen faster and earlier than ever before for this time of year, and it is saving motorists millions of dollars per day in lower fuel costs.
"Families taking trips this summer can expect to pay lower gas prices than recent years as long as there are not any refinery problems or significant international news events,” she added.
The current average gas price for New Jersey is $3.313; Pennsylvania, $3.461; and Delaware, $3.383.
