Transportation Costs by State 2026

Gas prices, commute time and the auto insurance environment for all 50 US states, sourced from AAA Gas Prices and Census ACS commute data. There is no composite transportation index here, because the federal price series does not publish one.

This page carries no transportation price index. The federal price-parity series used elsewhere on this site, BEA Regional Price Parities by State, does not publish one: transport goods fall inside its goods parity and transport services inside its other-services parity, and BEA does not break either out. The two tables are ordered by pump price. Sources: AAA Gas Prices (regular unleaded by state, sampled May 2026), Census ACS 5-year mean commute time.

What this page covers

Gas, maintenance, transit.

Transport spending covers gasoline, vehicle servicing, and transit fares where applicable, and for most households it is one of the larger line items after housing. This page ranks the one transport price with a public state-level source of its own, the AAA regular-unleaded pump price, and pairs it with commute time and the auto-insurance environment rather than blending them into a single index.

What it does NOT cover: vehicle purchase price (varies more by manufacturer than by state), auto insurance premiums (separately priced), commute time as a cost, parking, vehicle registration fees and state-specific fuel taxes (already priced into the per-gallon figure at the pump).

For full transportation-cost accounting, layer auto insurance premiums (Florida, Louisiana and Michigan are typically the most expensive; Maine, Idaho and Vermont the cheapest) and registration fees (highest in Oregon at ~$112 and Florida at $225 for two years) on top of the pump-price ranking.

Frequently Asked

Transportation costs, answered

Which states have the cheapest gas?
Mississippi, Louisiana, Oklahoma, Alabama, Arkansas and Texas all average around $3.00/gallon in the AAA reference data. Cheap gas correlates with proximity to refining infrastructure (Gulf Coast), low gas tax and low blended-fuel requirements.
Which states have the most expensive gas?
California ($4.85), Hawaii ($4.75), Washington ($4.30) and Nevada ($4.10) consistently lead the AAA per-state averages. California's high price reflects state taxes, summer-blend gasoline requirements and refining capacity constraints. Hawaii's reflects geographic isolation.
Does this page's transportation ranking include car insurance?
Partially, and less than you would like. There is no federal transportation price parity to point at: BEA puts transport goods inside its goods parity and transport services inside its other-services parity, and breaks out neither. Pump price, which is what this page ranks on, does not include car insurance premiums or vehicle purchase prices. Auto insurance varies widely by state; Florida, Louisiana and Michigan have the highest premiums (legal environment + no-fault history) and Maine, Idaho and Vermont the lowest.
How do commute times affect cost of living?
Indirectly. This page's pump-price ranking does not weight commute time directly, but longer commutes increase gas spend, vehicle wear and time cost. Maryland (32 min), New York (33 min) and New Jersey (31 min) have the longest mean commute. North Dakota (17 min), South Dakota (18 min) and Montana (18 min) the shortest. Remote-work eligibility radically changes the calculation; see the remote workers page.
Are there states with cheap gas but expensive transportation overall?
Alaska is the clearest example, and it is also where this page has to stop short. Gas at $3.85 a gallon is mid-tier, and the underlying cost pressure is real: high vehicle costs, limited transit, long distances and air-travel dependence. Hawaii is similar: per-gallon gas isn't extreme, but isolation pushes overall transport cost up.
What does AAA include in its state averages?
AAA publishes daily averages of regular, mid-grade, premium and diesel gasoline by state. The figures used here are regular unleaded, sampled May 2026 from gasprices.aaa.com. Daily and weekly variation can be 10-15 cents; treat any single point as a rolling average rather than a precise current price.
