It’s peak driving season in the US, and gasoline and diesel prices have never been this expensive this late in the year. Gas and diesel prices are at a record seasonal high, according to data from the American Automobile Association. Drivers are paying an average of $4 a gallon for gas and $5.40 a gallon for diesel in the second week of August for the first time ever. That comes as millions of Americans typically take to the road for vacations and family visits.

The record prices, reported on August 12, 2026, highlight the ongoing cost-of-living crisis. The American Automobile Association confirmed that these are the highest seasonal averages on record for this time of year. The surge affects both gasoline and diesel, straining household budgets during the summer travel period.

This price milestone underscores the persistent pressure on consumers, who are already facing elevated costs across other essentials. As the peak driving season continues, analysts are watching for any further increases that could deepen the financial strain on American families.
