Liability vs Full Coverage Car Insurance: Which Do You Need?

“Full coverage” sounds like it covers everything, but it does not. Here is what each part of a car insurance policy actually pays for, and how to decide what you need.

What liability coverage pays for

Liability insurance pays for harm you cause to other people. It has two parts: bodily injury liability, which covers other people’s medical bills and related costs, and property damage liability, which covers damage to their car or other property. It does not pay to repair your own car or treat your own injuries.

Almost every state requires drivers to carry some liability coverage, though the minimum amounts differ widely. State minimums are often low compared with the cost of a serious accident.

What “full coverage” really means

“Full coverage” is not an official policy type. It usually means liability combined with two coverages that protect your own vehicle:

• Collision: pays to repair or replace your car after a crash, no matter who is at fault, minus your deductible.
• Comprehensive: pays for non-crash damage such as theft, fire, hail, flooding or hitting an animal, minus your deductible.

Even “full coverage” has limits and exclusions, so read the policy rather than relying on the label.

Side-by-side comparison

When you need more than liability

• You have a car loan or lease. Lenders almost always require collision and comprehensive until the vehicle is paid off.
• You could not easily replace your car. If an accident would be a financial emergency, protecting your own vehicle is worth the extra premium.
• Your car is worth a lot relative to your savings. The higher the value, the more protection makes sense.

Choosing limits and deductibles

Minimum liability limits may not cover a serious accident, and you can be responsible for costs above your limits. Many consumer guides suggest considering higher limits if you have assets to protect. An independent agent or your state insurance department can help you judge what is appropriate.

A higher deductible lowers your premium but means you pay more out of pocket after a claim. Choose a deductible you could pay from savings without strain. If you finance a car, ask about gap coverage, which can pay the difference between what you owe and what the car is worth if it is totaled.

Frequently asked questions

Does full coverage cover everything?

No. It still has deductibles, limits and exclusions, and normal wear and mechanical breakdowns are not covered.

Is liability-only legal?

In most states, yes, as long as you meet the state minimums. Some states have additional requirements, so check your state’s rules.

Will my rate change if I switch coverage?

Almost always. Adding collision and comprehensive raises the premium. Compare quotes with the same limits and deductibles so you are judging like with like.

Do I need uninsured motorist coverage?

It protects you if you are hit by a driver with no insurance or too little. Many people find it inexpensive for what it offers, and some states require it.
