Stacker compiled statistics on gas prices in California using data from AAA. Gas prices are as of May 2. State gas tax data is from World Population Review. Three states, Connecticut, Georgia, and Maryland, have temporarily suspended gas taxes to help consumers while the cost of gas has increased.

Meanwhile, diesel prices reached a new record high of $5.16 per gallon on April 29. Prices climbed more than 16 cents over the weekend, hitting $5.32 per gallon on Monday, May 2.

For those whose careers are spent on the road like owner-operators—independent truck drivers who own their vehicles—filling their 250-gallon tanks for $1,300 can be prohibitive.

Experts warn that while drivers are currently feeling the pressure of the volatility of the global energy market, business owners and consumers will also start to feel this financial burden as higher costs are passed down the supply chain.
