When tens of millions of Americans hit the road this holiday weekend, they’re going to find the highest prices for gasoline in nearly seven years. And many will also find stations that don’t have any gas at all.

The national average price for a gallon of regular stands at $3.10, the highest since October 2014; in California, the average is $4.27. The average is up just 2% since Memorial Day, but 42% from a year ago, when pandemic restrictions brought demand to a near halt.
