Gas prices are falling along with demand, despite arrival of summer

Gas prices are falling across the nation, a pleasant surprise for U.S. drivers as fuel prices typically surge this time of year.

The average price for regular unleaded gas in the U.S. was $3.44 per gallon on Monday, down roughly 9 cents from a week ago, according to AAA. That's 19 cents less than a month ago and 14 cents less than last year, according to the auto club. 

Gas prices are falling because demand for fuel has weakened and oil prices have tapered off, energy experts said, an unusual set of circumstances for the summer season when fuel demands generally peak as more Americans go on road trips for vacation.
