Car insurance coverage types fall into two groups: coverage that pays other people when you cause a crash, and coverage that pays you for your own car and injuries. The core types are liability, collision, comprehensive, personal injury protection (PIP) or medical payments, and uninsured/underinsured motorist coverage. Add-ons such as gap insurance and rental reimbursement fill smaller gaps.
Each coverage has its own limit and, for some, a deductible. Your state requires some of them. Your lender may require others. The rest are your choice.
This guide explains what each coverage does, what it does not do, and how to decide what you need. It is general education, not insurance advice. Your policy wording is what counts, so read your declarations page and policy, and ask your insurer or agent about anything unclear.
What are the main types of car insurance coverage?
A standard auto policy is a bundle of separate coverages, each with its own price. The Insurance Information Institute (III) lists six that make up a basic policy (III, accessed October 2026). Here they are side by side:
| Coverage | Whose loss it pays | What it pays for | Usually required? |
|---|---|---|---|
| Bodily injury liability | Other people | Injuries and deaths you cause | Yes, in nearly every state |
| Property damage liability | Other people | Damage you cause to others’ cars and property | Yes, in nearly every state |
| Collision | You | Damage to your car from a crash or rollover | No, but lenders often require it |
| Comprehensive | You | Theft, fire, weather, animals, glass, vandalism | No, but lenders often require it |
| PIP or medical payments | You and your passengers | Medical bills; PIP may add lost wages | Required in no-fault and some other states |
| Uninsured/underinsured motorist | You and your passengers | Your injuries when the at-fault driver has no or too little insurance | Required in many states |
What does liability insurance cover?
Liability insurance pays for injuries and property damage you cause to other people with your car. It also usually pays for your legal defense if you are sued after a covered crash.
Liability has two parts:
- Bodily injury liability pays other people’s medical bills, lost income, and pain and suffering claims, up to your limit.
- Property damage liability pays to repair or replace other people’s cars and property, such as fences, mailboxes and buildings.
Limits are often written as three numbers, like 50/100/50. That means $50,000 of bodily injury coverage per person, $100,000 per accident, and $50,000 for property damage. If the costs of a crash go over your limits, you may have to pay the rest yourself.
What is the difference between collision and comprehensive?
Collision pays for damage to your car from hitting something. Comprehensive pays for almost everything else that can damage or take your car.
Collision coverage
Collision pays to repair your car, or pays its value if it is totaled, after a crash with another vehicle or an object, or a rollover. It pays no matter who caused the crash. If another driver was at fault, your insurer may try to recover the money from that driver’s insurer. This process is called subrogation, and it can also return your deductible to you.
Comprehensive coverage
Comprehensive, sometimes called “other than collision,” covers events such as:
- Theft of the car or its parts
- Fire, hail, windstorms and flooding
- Falling objects, such as tree limbs
- Hitting a deer or other animal
- Vandalism and broken glass
How payouts work
Both coverages usually pay the actual cash value of your car if it is totaled.
Both also come with a deductible, the amount you pay before the insurer pays. A higher deductible usually means a lower premium.
What is “full coverage” car insurance?
“Full coverage” is not an official type of policy. People usually use it to mean liability plus collision and comprehensive. Lenders and leasing companies often require that combination until the car is paid off.
The phrase can be misleading. A “full coverage” policy can still have low liability limits, a high deductible, and no rental car or gap coverage. When you compare policies, look at each coverage and limit, not the label.
How do PIP and medical payments coverage work?
Personal injury protection (PIP) and medical payments coverage (MedPay) both pay medical bills for you and your passengers after a crash, no matter who caused it. PIP usually pays for more than MedPay.
| Feature | PIP | Medical payments (MedPay) |
|---|---|---|
| Medical bills | Yes | Yes |
| Lost wages | Often | Usually not |
| Replacement services (such as childcare or housework) | Often | No |
| Funeral costs | Often | Often |
| Where it is required | No-fault states and a few others | Required in only a few states; optional elsewhere |
PIP is required in the no-fault states, where it is your first source of payment for crash injuries. Our guide to no-fault vs at-fault states explains how PIP works with the right to sue. In New Jersey, for example, the standard policy requires at least $15,000 of PIP, and the state’s buyer’s guide explains PIP choices (New Jersey Department of Banking and Insurance, 2026 edition).
What does uninsured and underinsured motorist coverage do?
Uninsured motorist (UM) coverage pays when a driver with no insurance causes a crash that injures you. Underinsured motorist (UIM) coverage pays when the at-fault driver’s limits are not enough to cover your costs.
Key points:
- Bodily injury UM/UIM pays for injuries to you and your passengers. In many states it also applies in hit-and-run crashes.
- Property damage UM (UMPD) pays for damage to your car, but it is not offered in every state.
- Depending on your policy and state, UM/UIM can also protect members of your household as passengers or pedestrians. Check your policy wording.
What optional add-ons are worth knowing about?
Add-ons, often called endorsements, are extra coverages you can attach to a policy. Most are inexpensive compared with the core coverages, but availability varies by insurer and state.
- Gap insurance. Pays the difference between your car’s actual cash value and what you owe on a loan or lease if the car is totaled or stolen. The III suggests considering it if you put less than 20 percent down, finance for 60 months or longer, or lease, and notes that leases generally require it (III, accessed October 2026).
- Rental reimbursement. Helps pay for a rental car while your car is being repaired after a covered claim, up to a daily and total limit.
- Roadside assistance or towing. Helps with towing, jump-starts, flat tires and lockouts.
- Rideshare coverage. Fills gaps when you drive for a rideshare or delivery app. A personal policy may exclude this use, so check before you start.
- Custom parts and equipment. Covers aftermarket add-ons, such as custom wheels or a sound system, above a basic limit.
- New car or better car replacement. Some insurers offer to pay for a new car instead of the depreciated value if a fairly new car is totaled.
How do limits and deductibles affect your coverage?
Limits set the most your policy will pay. Deductibles set what you pay first on your own-car claims. Together, they shape both your protection and your price.
| Choice | Raise it | Lower it |
|---|---|---|
| Liability limits | More protection for your savings; higher premium | Less protection; lower premium |
| Collision and comprehensive deductible | Lower premium; more out of pocket per claim | Higher premium; less out of pocket per claim |
The NAIC notes that you can lower your premium by accepting more risk, such as a higher deductible, and that many people buy more than the minimum required coverage (NAIC, last updated September 26, 2025). As a rule of thumb, pick a deductible you could pay from savings, and liability limits that reflect what you own and earn. Your rating factors, such as driving record and location, also affect price. We explain them in how car insurance rates are calculated.
Which coverages do you actually need?
The right mix depends on your state, your car and your finances. A simple way to decide:
- Start with your state’s requirements. Every policy must meet these.
- Add enough liability to protect what you own. The minimum may not be enough if you have savings, a home or a steady income.
- Decide on collision and comprehensive. If your car is financed or leased, your lender will usually require them. If your car is older and worth little, you might weigh the premium against the car’s value.
- Consider UM/UIM even if optional. It protects you from other drivers’ choices.
- Add gap if you owe more than the car is worth. This is common in the first years of a loan or lease.
- Skip add-ons you already have elsewhere.
The bottom line
Car insurance is a set of separate coverages, not one product. Liability protects other people from you. Collision and comprehensive protect your car. PIP, MedPay and UM/UIM protect you and your passengers. Once you know what each one does, your declarations page becomes much easier to read, and you can make clear choices about limits, deductibles and add-ons. When in doubt, ask your insurer or your state insurance department to explain any coverage before you buy.
