What are the average gas prices by state in 2025?

As of the latest AAA survey, gas prices in the United States vary significantly by state. The national average hovers around $3.50 per gallon for regular gas, but state-by-state prices range from as low as $2.70 to over $4.90. California currently leads the nation with the highest average price at $4.92 per gallon, while Alabama and Arkansas offer some of the lowest, both under $2.75. These differences can add up quickly, especially for summer travelers planning long road trips.

Which states have the cheapest gas for summer road trips?

If you're looking to save on fuel this summer, consider traveling through the South and parts of the Midwest. Alabama ($2.74), Arkansas ($2.75), Mississippi, and Louisiana are among the states with the lowest average gas prices. These regions consistently offer more affordable fuel due to lower state taxes and proximity to Gulf Coast refineries. Planning your route through these states could significantly reduce travel costs, especially for RV users or families taking multi-state road trips.

Why do gas prices vary so much across the U.S.?

Several factors contribute to gas price differences by state. State taxes and environmental regulations play a major role. For example, California imposes some of the highest fuel taxes and requires a unique gasoline blend to reduce emissions, which raises costs. Meanwhile, states like Texas and Louisiana benefit from being near oil production and refining hubs, resulting in lower transportation and production costs. Local demand, competition among gas stations, and seasonal travel trends also influence prices.

How can travelers save money on gas this summer?

There are several practical ways to reduce fuel expenses during summer travel. First, use apps like GasBuddy or Waze to find the lowest gas prices along your route. Second, maintain your vehicle — proper tire pressure and timely oil changes can improve fuel efficiency. Third, consider driving at steady speeds and avoiding rapid acceleration, which burns more fuel. Finally, plan your itinerary to minimize backtracking and idle time, especially in congested tourist areas.

Is gas more expensive in tourist-heavy states?

Often, yes. States with high tourism traffic, such as California, Hawaii, and Nevada, tend to have higher gas prices. This is partly due to increased seasonal demand and partly due to logistical factors — for example, Hawaii's prices are inflated by the cost of transporting fuel to the islands. Travelers visiting popular summer destinations should budget for elevated fuel expenses and look for cheaper refueling options on the outskirts of major cities or tourist hotspots.
