Why do car insurance rates differ from state to state?

Location can impact car insurance rates because the risks vary. That's why you'll find insurance rates differ from state to state. It also explains why the cost of car insurance from the same insurance company also changes depending on the state you live in.

Here are a few location-based reasons car insurance rates differ across states:

• Crime rates. Areas more prone to theft and vandalism are more expensive than safer ones.
• Population density. Urban areas tend to have higher claims rates than small, rural areas, likely due to increased traffic.
• Number, frequency and cost of claims. The greater prevalence and cost of claims in a given area can bump up your car insurance.
• Weather trends. Areas more prone to severe weather and damage due to these trends will also be more expensive. In turn, areas that are less prone to extreme weather might have cheaper insurance.
• The cost of medical care and car repairs. These costs vary by state and can also affect the cost of car insurance. 

How to find the cheapest car insurance coverage in your state

Besides using our handy tools, you'll want to start by shopping around to get the cheapest car insurance. Gather at least three quotes to compare similar liability limits and deductibles.

Other ways to save on your car insurance include:

Looking for discounts. Insurers typically offer several ways to save on your car insurance, such as:

• Bundling your policy with homeowners/renters insurance
• Being a safe driver and maintaining a clean record
• Installing anti-theft devices
• Setting up autopay
• Getting insurance through a group affiliation
• Not putting a lot of miles on your car
• Staying with the same insurer for several years

Maintaining strong credit. Insurers might use what's known as a credit-based insurance score to place you in a risk category and to figure out the cost of your insurance. Like a consumer credit score, this is a three-digit number. There are only a few states where this is not legal.

Choosing a high deductible. A higher deductible means a lower monthly premium. However, you'll want to make sure you have enough money in the bank to cover your deductible should you need to file a claim.

Purchasing barebones insurance. If you drive an older car, purchase only liability coverage and skip the comprehensive and collision insurance. Let's say your car is more than 10 years old or worth less than $3,000. In that case, you might not need full coverage. And if you don't drive your car often, you might be able to squeak by with cheap state minimum car insurance.

Review your policy at least once a year. You can switch car insurance policies and insurers at any time. Use that to your advantage and save some money that way. Check your policy to make sure it's a good fit for you. Maybe you've driven far less in the past year. In that case, you might want to switch to a low-mileage policy. Next, gather a few quotes from your current insurer and competitors. Just make sure it's the same coverage types and coverage limits.

Our recommendation

For comprehensive car insurance protection, we recommend opting for full coverage car insurance. Full coverage typically includes liability insurance, collision coverage, and comprehensive coverage. 

While getting less coverage — such as the state minimum — will cost less, you could end up spending a lot more in the long run if you’re in an accident. There are better ways to save. Here are some tips to help you find the best rates:

• Shop around. Different insurers offer different rates for the same profile. Compare quotes from multiple insurers to find the most competitive rate.
• Bundle policies. Many insurers offer discounts if you bundle your car insurance with other policies, such as homeowners or renters insurance.
• Maintain a clean driving record. Drivers with no recent accidents or traffic violations typically qualify for lower premiums.
• Increase your deductible. Opting for a higher deductible can lower your premium, but be sure you can afford the out-of-pocket cost if you need to file a claim.
• Look for discounts. Ask about available discounts, such as those for safe drivers, low-mileage drivers, or vehicles with safety features.
• Improve your credit score. Insurers often consider your credit score when determining rates. A better credit score can lead to lower premiums.

By combining full coverage with strategic shopping and discounts, you can achieve comprehensive protection for your vehicle at an affordable rate.
