Gas prices are entering the summer driving season at record levels, with the national average hitting $4.45 on May 2—the highest ever for that date.

That’s up about $1.28 from a year ago, according to AAA, with prices rising across nearly every region.

The milestone underscores ongoing volatility in fuel markets, driven in part by the escalating conflict involving Iran, which has disrupted global oil supplies and pushed crude prices higher.

It also suggests the usual seasonal run-up is starting from a much higher baseline. For consumers, that likely means higher transportation costs and continued pressure on household budgets.

Meanwhile, in the Midwest, Illinois stands out at $4.93 per gallon, while much of the region remains in the mid-$4 range. While Southern states remain comparatively cheaper, prices are climbing there as well, with Georgia at $3.85, Texas at $3.92 and Florida higher at $4.34.

Beyond gasoline, other fuel costs are rising even faster. Diesel has climbed to $5.64, up about $2.09 over the past year. As a key fuel for freight, shipping and public transportation, it is especially sensitive to supply disruptions — and its rising cost can quickly ripple through the broader economy, pushing up prices on everything from groceries to goods.

The surge underscores the broader economic risks tied to the standoff, as uncertainty around the Strait of Hormuz continues to weigh on energy markets.
