WASHINGTON, DC (May 21, 2026) – As holiday travelers start hitting the road today in record numbers, Memorial Day weekend gas prices are the highest they’ve been in four years. The national average for a gallon of regular is at $4.56, up 3 cents over last week and $1.38 higher than this time last year. Current prices are close to what drivers were paying 4 years ago, when the national average on Memorial Day was $4.61. With gasoline demand on the rise and the prolonged closure of the Strait of Hormuz, pump prices are likely to remain elevated as the summer travel season gets underway.
