 Road trips are not going to break the bank this fourth of July. GasBuddy projects the national average for regular gas will stand at $3.49 a gallon on Independence Day. That's a penny shy of the price a year ago and down sharply from $4.79 two years ago when oil prices spiked after Russia invaded Ukraine. Adjusted for inflation, U.S. gas prices are almost exactly where they were in July of 2018.
