Car Insurance Coverage Explained: What Each Part of Your Policy Pays
Key takeaways
- A car policy is a bundle of separate coverages, each priced on its own. The NAIC's consumer guide says there is "no such thing" as a full coverage policy.
- Liability pays other people. Collision and comprehensive pay for your car. PIP, MedPay and UM/UIM pay for your injuries.
- The numbers that matter most are your liability limits and your deductibles. The guides below show how to pick both.
This page is the map for the coverage section of our car insurance guide. Every coverage on your declarations page is listed here in one line, with a link to the page that explains it in full. If you only read one section, read the one on liability limits, because that is the coverage that protects your savings when you cause a crash.
What are the main types of car insurance coverage?
The Insurance Information Institute (Triple-I) describes a basic auto policy as six coverages: bodily injury liability, personal injury protection, property damage liability, collision, comprehensive, and uninsured/underinsured motorist. It notes that "each type of coverage is priced separately," which is why two quotes for the same car can look so different. Add-ons such as gap, rental reimbursement and towing sit on top.
| Coverage | Who it pays | What it pays for | Required? |
|---|---|---|---|
| Bodily injury liability | Other people | Injuries you cause to others | Required in nearly every state |
| Property damage liability | Other people | Damage you cause to their car or property | Required in nearly every state |
| Collision | You | Your car after a crash, rollover or pothole | Optional by law; lenders usually require it |
| Comprehensive | You | Theft, hail, fire, flood, animals, falling objects | Optional by law; lenders usually require it |
| Uninsured/underinsured motorist | You and your passengers | Injuries (and in some states car damage) caused by a driver with no or too little insurance | Required in 20 states and D.C., per Triple-I |
| PIP or MedPay | You and your passengers | Medical bills; PIP can also pay lost wages | Required in no-fault states |
| Gap | Your lender, on your behalf | The difference between your loan balance and the car's value after a total loss | Optional; often required on leases |

What does liability insurance cover, and how much do you need?
Liability is the part of the policy the law cares about. It pays for injuries and damage you cause to others, up to your limits, and you owe anything above them. Limits are written as three numbers, such as 25/50/25. Our explainer what does 25/50/25 mean walks through each number with a crash example, and the how much car insurance do I need calculator turns your assets and household into a recommended limit set. The NAIC's advice is direct: buy "the most coverage you can reasonably afford to protect your financial security."
Each state sets its own floor. Our state minimums hub tracks what each state requires.
What does full coverage mean?
"Full coverage" is shorthand for liability plus collision plus comprehensive. It is not a product you can buy, and it leaves gaps. Start with what full coverage car insurance covers, then use comprehensive vs collision to see which one pays for a deer, a pothole, hail or a break-in. Triple-I's analysis of 2023 NAIC data found that 80 percent of insured drivers buy comprehensive and 77 percent buy collision.
How do you choose a deductible?
Your deductible is what you pay on each collision or comprehensive claim before the insurer pays. A higher deductible lowers the premium and raises your out-of-pocket cost when you claim. $500 vs $1,000 deductible shows the break-even math using your own quote and national claim frequency data.
When should you drop collision and comprehensive?
On an older, paid-off car, the coverage can cost more than it could ever pay out. When to drop full coverage gives a worked method, and the liability-only vs full coverage break-even calculator runs the numbers on your car.

What protects you from drivers with no insurance?
According to the Insurance Research Council, cited by Triple-I, 15.4 percent of motorists were uninsured in 2023, more than one in seven. Uninsured motorist (UM) coverage pays when the at-fault driver has no insurance or drives away. Underinsured motorist (UIM) coverage pays when their limits run out. Read is uninsured motorist coverage worth it for the decision, and UM vs UIM for how the two differ and how stacking works.
Who pays your medical bills after a crash?
In no-fault states, your own personal injury protection (PIP) pays first, whoever caused the crash. Elsewhere you may carry medical payments (MedPay) coverage, which is narrower. The Texas Department of Insurance describes PIP as similar to MedPay but also paying "for things like lost wages and other nonmedical costs." MedPay vs PIP compares the two and shows where each applies.
What if you owe more than the car is worth?
Collision and comprehensive pay the car's actual cash value, not your loan balance. If the car is totaled early in a long loan, the difference is yours to pay unless you carry gap coverage. Do you need gap insurance covers who needs it, dealer versus insurer gap, and whether you can still add it.
Before you change anything: pull your declarations page. It lists every coverage, limit and deductible on your policy. Compare quotes only against identical limits and deductibles, which the NAIC recommends in its shopping guide.
