Car insurance in Wyoming

Wyoming is the cheapest state for auto insurance with an average annual premium of $1,140 per year. There are many reasons why car insurance in Wyoming tends to be so inexpensive compared to other states. Reasons may include its low population density, fewer urban areas, minimal traffic congestion, favorable state regulations, and beneficial competition among insurers.

Car insurance in Vermont

Vermont is the second-cheapest state for auto insurance with an average annual premium of $1,237 per year. One of the reasons why Vermont has cheap car insurance is because it has a very low population density. It’s also largely rural, which contributes to low car insurance rates. With few drivers on the road at any given time, the risk of an accident goes down, and so does the average cost of car insurance in the state. 

Car insurance in Maine

Maine is the third-cheapest state for auto insurance, with an average annual premium of $1,255. Maine is a mostly rural state and it has very few uninsured drivers. According to the Insurance Information Institute (Triple-I), just about 5% of Maine drivers are uninsured. Only a few states have fewer uninsured drivers than Maine. However, the average cost of car insurance might be higher in Maine’s urban areas, such as Portland and Bangor. 

Car insurance in Idaho

Idaho is the fourth-cheapest state for car insurance. The average premium in Idaho is $1,362 per year. Like Vermont, Idaho is mostly rural, which corresponds to lower auto insurance costs. In addition, Idaho does not experience many extreme weather events which can potentially damage insured vehicles. When insurance companies aren’t dealing with frequent claims, the cost of auto insurance is often more affordable for drivers in the area. 

Why some states have less expensive insurance than others

Car insurance companies consider a variety of factors to calculate car insurance rates in a specific location. For example, the population density, the number of uninsured drivers, and the number of accidents in the area are just a few of the criteria that can contribute to the cost of car insurance.  

Auto insurance companies also consider the number of claims that drivers file in specific locations. For instance, if thousands of drivers start filing vehicle theft claims, insurance companies might raise rates for drivers in that state. Similarly, if drivers continuously file weather-related claims in a certain state, rates might go up due to increased damage risks. 

The amount of car insurance that is required in the state can also affect the average premium. In states that have low minimum coverage requirements, car insurance rates can be more affordable. Conversely, in states that have higher coverage requirements, car insurance premiums can be more expensive.  

Keep in mind that the average cost of car insurance isn’t just determined by your state. Insurance companies also look at your city and ZIP code when calculating your personalized rate. Even if you live in a state with low car insurance rates, you could pay more than the statewide average based on your specific location.

The best way to find the cheapest car insurance company for you is to compare rates from several insurance providers.
