Shopping for auto insurance doesn’t need to feel overwhelming. Understanding the different types of coverage can make it easier to decide what protection makes sense for your car, budget and driving habits.

Why understanding car insurance coverage matters

There are several common types of car insurance coverage, including liability, collision, comprehensive and uninsured or underinsured motorist coverage. Some coverages are required by law, while others are optional but may offer valuable financial protection.

Here’s a closer look at the main types of car insurance coverage, what each one protects and how to build coverage that works for you.

Liability insurance: protecting others after an accident

Auto insurance is required by law in almost every state. Liability is often a required car insurance coverage that drivers must have.

Liability insurance coverage pays for the injuries and property damage you cause to others in an accident, including their injuries and property damage. It won’t pay for your injuries or repairs to your car.

It has two parts:

• Bodily injury liability helps pay for medical treatment, rehabilitation and legal costs if an injured person sues you.
• Property damage liability covers damage you cause to another vehicle or someone else’s property.

Every state sets its own minimum coverage requirements, but drivers can carry more. For example, in Wisconsin, the required minimums are $25,000 per person injured, $50,000 per accident, and $10,000 for property damage. 

Collision insurance: protecting your vehicle after a crash

Collision coverage helps pay to repair or replace your car after a crash, even if you caused it. It usually only covers damage caused by contact with another car or object. So, if your vehicle is stolen, damaged in a hailstorm or vandalized, it won’t be covered under collision.

Your deductible is what you pay out of pocket when your coverage kicks in. If you have a $500 deductible and $3,500 in damage, you pay $500, and your insurer covers the rest, up to your car’s actual cash value.

Another point to consider is that if you lease or finance your vehicle, you may be required to have collision coverage.

Comprehensive insurance: coverage beyond collisions

Comprehensive insurance coverage helps pay for damage to your vehicle from causes other than a crash, including theft, vandalism, windshield damage, animal collisions or covered acts of nature. It may be required if you lease or finance your car.

If your vehicle is damaged by a falling branch, comprehensive coverage can help pay for repairs or vehicle replacement.

The difference from collision insurance is that collision covers what happens when your car hits something, while comprehensive covers most of what happens to it outside of that, within your policy’s limits. 

What is full coverage car insurance?

Full coverage auto insurance isn’t its own policy. It's a term for carrying liability, collision and comprehensive coverage. Some drivers may also want optional car insurance coverage, such as rental car reimbursement. When layered together, full coverage can provide broader protection after an accident.

It’s important to understand that full coverage, while offering extensive protection, still has its limits. It generally won’t cover mechanical breakdowns, routine maintenance or normal wear and tear on your vehicle.

Uninsured and underinsured motorist coverage

Uninsured motorist coverage helps pay for your injuries and property damage when an at-fault driver has no insurance. Underinsured insurance steps in when the other driver has some coverage but not enough to cover the bill.

Research by the Insurance Research Council shows 33% of drivers are uninsured or underinsured. The gap has grown since 2017, which means there's a higher chance that if someone hits your car, they won’t have insurance.

Uninsured and underinsured motorist coverage helps cover these expenses. In some states, this insurance also covers damage and injuries from a hit-and-run.

Building a car insurance policy that fits your needs

The right mix depends on your car, budget and your risk levels.

For example:

• The driver of a new financed car may want to pair liability with collision and comprehensive coverage, since a loss would be expensive, and lenders usually require it.
• The driver owns an older car with low value may want liability minimums plus uninsured motorist coverage, since their repair and replacement costs are lower, and dropping collision reduces the premium.

It’s worth reviewing your coverage yearly or after a big change, like buying a car, moving, or paying off a loan. Comparing quotes and talking through your situation with an agent can help you find coverage that fits.
