To identify the best and worst states to drive in across the U.S., the study looked at five categories of data that together create a comprehensive view of the driving experience in each location. Those categories include:
- Cost: This category includes factors like gas prices per gallon, annual car maintenance costs and annual toll expenses per vehicle comprise this category; it also includes average annual premiums from the cheapest full coverage auto insurance options available in each state.
- Congestion: This category includes indicators like average morning commute times and vehicle miles traveled per lane mile, which measures how many vehicles are using a particular length of road over a certain period of time.
- Safety: For this category, the study analyzed fatal crashes per 100,000 people and car thefts per 100,000 vehicles.
- Infrastructure: This category includes the percentage of roads and bridges that are in acceptable condition in each state.
- Weather: For this category, the study analyzed the total number of fatal car crashes per 100,000 people in both snowy and rainy conditions.
Within these five categories, the study broke down the best and the worst states across different data points and highlighted them below.

Methodology
To explore and rank driving experience by state, the study considered 12 metrics across five categories — congestion, cost, infrastructure, safety, and weather. Each metric was assigned a specific weight, which was then used to calculate a final ranking score through a weighted average. Assigned weights are expressed below within parentheses for each metric. The state with the lowest final ranking score ranks as the worst place to drive in.
Cost (20%)
- Gas prices: This is per gallon for mid-grade gas. Data was collected using CollectAPI's Gas Prices API and was accessed in May 2023. (5%)
- Annual toll costs per vehicle: This is government spending on highways funded by toll revenue per state divided by the number of registered vehicles per state. This data comes from the Federal Highway Administration and is for 2020. (5%)
- Annual auto insurance premiums: This is the cheapest full coverage auto insurance options in each state. Data comes from state insurance departments and Quadrant Information Services and reflects the most recent quotes as of July 2023. (5%)
- Annual maintenance costs: Data comes from CarMD and is for 2021. (5%)
Congestion (25%)
- Vehicle miles traveled per lane mile (in thousands): This measures how many vehicles are using a particular length of road over a certain period of time, i.e. traffic density. For this metric, for every single mile-long stretch of a lane, cars in these states cover this amount of miles in a year. Data comes from the Federal Highway Administration and is for 2021. (12.5%)
- Average commute times: Data is expressed in minutes and comes from the Census Bureau's 2021 one-year American Community Survey. (12.5%)
Safety (25%)
- Fatal car crashes per 100,000 people: Number of car crash fatalities divided per 100,000 population. Data comes from the National Highway Traffic Safety Administration and is for 2021. (18.75%)
- Car thefts per 100,000 vehicles: Number of car-theft-related arrests per 100,000 vehicles. Data comes from the Federal Bureau of Investigation's Crime Explorer and is for 2021. (6.25%)
Infrastructure (20%)
- Percentage of roads in acceptable condition: Acceptability of roads is determined based on the International Roughness Index (IRI), with lower IRI values indicating smoother roadways. "Acceptable" in this context is considered an IRI <=170, which includes roadways both rated as "Good" and "Fair". Data comes from the Bureau of Transportation Statistics and is for 2020. (15%)
- Percentage of bridges in acceptable condition: A bridge is considered "acceptable" if it gets a score of at least 5 out of 10. Comparatively, a bridge in excellent shape would score 7 or above, while one in poor condition would get a score of 4 or less. This rating comes from assessing various components of the bridge such as the surface used for walking or driving, the underlying structure, and other elements. Data comes from the Bureau of Transportation Statistics and is for 2022. (5%)
Weather (10%)
- Car fatalities in rainy weather per 100,000 people: Data comes from the National Highway Traffic Safety Administration and is for 2020. (5%)
- Car fatalities in snowy weather per 100,000 people: Data comes from the National Highway Traffic Safety Administration and is for 2020. (5%)
