It's important to note that a state's average cost of auto liability insurance does not reflect its minimum coverage limits.

What is liability auto insurance?

Liability car insurance helps cover repair costs, court fees and medical expenses that can occur after an accident you cause. There are two key parts to liability car insurance:

  1. Bodily injury coverage: This portion of your liability car insurance pays for the medical costs of others you injure in an accident. It also covers legal fees if you're sued as a result of the accident. Bodily injury coverage has limits for both a person injured in an accident, and the total number of people injured in an accident.
  2. Property damage coverage: This coverage helps to pay for damage you cause to another's car or personal property.

It's important to reiterate that liability auto insurance does nothing for your own damages after an accident. In order for your damages and injuries to be covered, you need collision insurance.

What factors affect liability car insurance cost?

Your final rate for liability car insurance is based on many different factors, some of them more under your control than others. These include:

Your insurance history

If you have auto accidents, speeding tickets or DUIs on your insurance record, this increases your risk level for filing a claim. Auto insurers will raise your rates in order to compensate for their potential costs of covering you.

The car you drive

The make and model of your car, as well as its age, will factor into the cost of your liability car insurance. You can expect to pay more if you've had custom work done on the car as well.

Your chosen coverage limits

If you raise your auto liability limits, you will see an increase in your rate. Despite the increase in cost, we highly recommend raising the limits of your minimum-coverage insurance. States do not frequently increase their car liability coverage requirements, which can lead to insufficient coverage for you. If you wind up being responsible for an accident resulting in a long court case or hospital stay, your coverage limits can easily be surpassed. Any costs associated with the accident beyond your limits will have to be paid out of your own pocket.

In order to avoid this, we recommend raising your auto liability limits to 100/300/100. Despite the higher coverage levels, the cost difference in premiums isn't that expensive.

How to find cheap liability car insurance coverage

Comparing quotes, choosing the right deductible and taking advantage of your insurer's discount offers can significantly reduce your current car insurance rates. Taking a careful hand when choosing the policy you want can yield lower insurance costs.

Compare car liability insurance quotes

Car insurance companies offer different prices for the same liability coverage. Providers put different weights on different risk factors when calculating your quote. For example, one company may put a heavier weight on how old your car is than another company does. In order to make sure you're getting the best liability coverage at your best cost, compare car insurance quotes from multiple insurers.

Be careful with your deductible

When you raise your car insurance deductible, you lower your premium. Look at your auto insurance claim history. If you don't have many, or preferably any, claims on your record, consider taking a higher deductible. While you would have to pay more should you have to file a claim, the premium savings over time can be worth it.

Look at discounts available

In order to stay competitive, car insurers offer various discounts to attract policyholders. For example, many providers offer a bundling discount where, if you bundle your car insurance policy with a life, renters or homeowners insurance policy, you can get big savings on both policies. When looking at an insurer, make sure to ask them about all the discounts available to you.
