From truckers to commuters, gasoline prices are squeezing budgets across the country. And the pain at the pump will not let up anytime soon.

With peace talks between the United States and Iran appearing deadlocked, the average cost for a gallon of regular gasoline rose to $4.18 – its highest level in four years according to AAA.

The last time Americans paid this much to fill their tanks was after Russia’s invasion of Ukraine.

Gasbuddy petroleum analyst Patrick De Haan had a sobering forecast for Americans. The national average could tick up to $4.20 on Tuesday and could soon reach $4.30 a gallon, he told USA TODAY.

The problem? Oil prices are on a steady upward march as peace negotiators indicated an impasse in negotiations to reopen the Strait of Hormuz.
