Gas prices in Illinois have officially hit record levels as tensions continue to grow between the U.S. and Iran over the Strait of Hormuz.

With a U.S. blockade of the Straight in place, prices at the pump across the state officially hit six dollars a gallon for diesel, eclipsing the previous record set in early May.

Looking to fill up? Gas Buddy’s Head of Petroleum Analysis, Patrick DeHaan, says prices at the pump are only going to get more expensive.

To help circumvent the high prices, the U.S. continues to release fuel from the Strategic Reserve.

Earlier this week, President Trump floated the idea of temporarily eliminating the federal gas tax; however, that would require congressional approval.
