Gas prices have decreased in most U.S. states, but the price relief may be short-lived if negotiations between the U.S. and Iran sour.
Patrick De Haan, the head of petroleum analysis at GasBuddy, noted on Monday that gas prices had fallen to a national average of $4.45 per gallon, while diesel had fallen to a national average of $5.56 per gallon, which was beyond more optimistic predictions heading into the week. According to AAA, the national average for gasoline last week was $4.53 per gallon, and $5.65 per gallon for diesel.
