In addition to record travel this Memorial Day, the U.S. DOT reports that March broke the record for the most vehicle miles traveled (VMT). Gas prices, though rising since late March, are predicted to drop and remain low through the end of 2015.
Gas prices have been dropping for a month. According to the chief oil analyst with the Oil Price Information Service in this radio interview, expect prices to continue dropping to as low as $3.25 a gallon, but don't expect lower than $3.00.
