What Your Car Insurance Actually Covers — And What It Doesn't

The three main types of car insurance coverage

Car insurance policies combine three separate types of coverage, and each one protects against different kinds of loss. Liability coverage pays for damage or injury you cause to someone else. Collision coverage pays to repair or replace your own car after a crash. Comprehensive coverage pays for damage to your car from events other than crashes — theft, weather, vandalism, and animal strikes.

Most states require you to carry liability coverage by law. Collision and comprehensive are optional, though your lender will require them if you have a car loan or lease. The three types work independently: you can have liability without collision, or collision without comprehensive, depending on what you choose to pay for.

Your policy also includes smaller coverages that sit inside these categories. Medical payments coverage, uninsured motorist protection, and roadside information are common add-ons. Each one has its own limit — the maximum amount the insurance company will pay for that specific type of claim.

Key Takeaways

• Liability coverage pays for injuries or property damage you cause to others, and most states legally require it.
• Collision coverage pays to repair or replace your car after a crash, regardless of who caused it.
• Comprehensive coverage pays for damage from theft, weather, vandalism, and animal strikes — anything except collisions.
• Your policy limits determine the maximum the insurance company will pay, and choosing a higher limit costs more per month but protects you better.
• Deductibles reduce your monthly cost by making you pay the first portion of any claim yourself.

Liability coverage: what you owe when you cause an accident

Liability coverage has two parts. Bodily injury liability pays medical bills, lost wages, and pain-and-suffering damages for people you injure in a crash. Property damage liability pays to repair or replace the other person's vehicle or property you damage. If you hit a parked car, a fence, or a storefront, property damage liability covers it.

Your policy shows liability limits as three numbers, like 25/50/25. The first number is the bodily injury limit per person (in thousands of dollars), the second is the total bodily injury limit per accident, and the third is the property damage limit. So 25/50/25 means the insurance company will pay up to $25,000 per injured person, $50,000 total for all injuries in one accident, and $25,000 for property damage.

If the damages exceed your limits, you are personally responsible for the rest. If you cause a serious crash and injure multiple people, medical bills can easily climb past $50,000. This is why many people choose higher limits — 100/300/100 or more — even though it raises the monthly premium. The extra cost is usually small compared to the protection.

Collision coverage: repair costs after you crash

Collision coverage pays to repair your car after any crash, whether you caused it or the other driver did. It also covers single-vehicle accidents — hitting a tree, rolling over, or sliding off the road. The insurance company pays for repairs up to your car's actual cash value, minus your deductible.

Your deductible is the amount you pay out of pocket before insurance kicks in. Common deductibles are $500 or $1,000. If you have a $500 deductible and repairs cost $3,000, you pay $500 and insurance pays $2,500. If repairs cost $400, you pay the full $400 because it is less than your deductible, and insurance pays nothing.

Collision coverage does not cover wear and tear, maintenance, or damage from poor upkeep. It also does not cover injuries to you or your passengers — that is what medical payments coverage handles. If your car is totaled, the insurance company pays its actual cash value at the time of the crash, not what you paid for it or what you still owe on the loan.

Comprehensive coverage: theft, weather, and other non-crash damage

Comprehensive coverage protects your car from damage that is not caused by a collision. This includes theft, vandalism, broken windows, hail, flooding, fire, falling objects, and animal strikes. If a deer runs into your car, a tree branch falls on it during a storm, or someone breaks in and steals your radio, comprehensive coverage pays for the repairs.

Like collision coverage, comprehensive has a deductible. You pay the deductible, and insurance pays the rest up to your car's actual cash value. Comprehensive claims are usually faster to process than collision claims because there is no dispute about fault — a hailstorm or theft is not anyone's responsibility to prove.

Comprehensive coverage is optional if you own your car outright, but lenders and lease companies require it. The monthly cost is usually lower than collision coverage because comprehensive claims are less common. If you live in an area with frequent hail, heavy snow, or high theft rates, comprehensive becomes more valuable.

Medical payments and uninsured motorist coverage

Medical payments coverage (sometimes called MedPay) pays your medical bills and your passengers' medical bills after a crash, regardless of who caused it. It covers hospital visits, surgery, dental work, and sometimes funeral expenses. The limit is usually $1,000 to $5,000 per person. Medical payments coverage is optional but inexpensive, and it pays faster than waiting for a liability claim to settle.

Uninsured motorist coverage protects you if you are hit by a driver who has no insurance or whose insurance is not enough to cover your damages. It pays for your medical bills and vehicle repairs up to your uninsured motorist limit. If the other driver is uninsured and causes a serious crash, this coverage can be the difference between paying your own bills or having them covered.

Uninsured motorist coverage comes in two forms: bodily injury (for your medical bills) and property damage (for your car repairs). Some states require it; others make it optional. The cost is low because uninsured motorist claims are uncommon, but the protection matters in states where many drivers carry no insurance.

What car insurance does not cover

Car insurance does not cover maintenance, wear and tear, or damage from poor upkeep. If your brakes fail because you never replaced the pads, or your engine seizes because you never changed the oil, insurance will not pay. It also does not cover damage you cause intentionally or damage that happens while you are committing a crime.

Insurance does not cover damage to your car while it is being repaired by someone else, or damage that happens while someone else is driving your car without permission. If you lend your car to a friend and they crash it, your collision coverage will pay — but if they damage it while doing something illegal, the claim may be denied.

Rideshare and commercial use are not covered under a personal auto policy. If you drive for Uber or Lyft, you need rideshare coverage. If you use your car for business deliveries or as a taxi, a personal policy will not cover accidents that happen during that work. Using your car for commercial purposes and filing a claim under a personal policy is grounds for denial.

How deductibles and limits affect your monthly cost

Your monthly premium depends on the coverage types you choose, the limits you set, and the deductible you pick. Raising your deductible from $500 to $1,000 lowers your monthly payment because you are agreeing to pay more out of pocket when a claim happens. Raising your liability limit from 25/50/25 to 100/300/100 raises your monthly payment because the insurance company is taking on more risk.

The relationship is not always obvious. Raising your collision deductible might save $20 per month, but if you have a $2,000 repair, you now pay $1,000 instead of $500 — a difference of $500. Over two years, you save $480 in premiums but lose $500 in a single claim. The math works differently for everyone depending on how often you expect to file claims.

Most people choose a deductible they can afford to pay if a claim happens, then set liability limits higher than the legal minimum. A $1,000 deductible is common because it balances monthly savings with reasonable out-of-pocket risk. Liability limits of 100/300/100 or higher are common because the monthly difference is small but the protection is much larger.

Frequently Asked Questions

Does car insurance cover accidents that are my fault?

Collision and comprehensive coverage pay for your car's repairs regardless of fault. Liability coverage pays for damage you cause to others. If you cause a crash, your collision coverage pays to fix your car (minus your deductible), and your liability coverage pays for the other person's damages. Your rates will likely increase after a at-fault accident.

What happens if I hit someone and my liability limit is too low?

You are personally responsible for any damages above your policy limit. If you cause $100,000 in injuries and your limit is $50,000, you owe the remaining $50,000. The injured person can sue you, garnish your wages, or place a lien on your home. This is why many people carry higher limits than the legal minimum.

Does insurance cover my belongings if they are stolen from my car?

No. Car insurance covers damage to the vehicle itself, not personal property inside it. If someone breaks your window and steals your laptop or phone, comprehensive coverage pays for the broken window but not the stolen items. Your homeowners or renters insurance may cover personal property theft, depending on your policy.

Will insurance pay if I cause an accident while driving for work?

Personal auto insurance does not cover accidents during commercial use. If you drive for your job — making deliveries, visiting clients, or transporting goods — you need commercial auto coverage. Rideshare drivers need rideshare coverage. Using a personal policy for commercial driving and then filing a claim can result in denial.

What is the difference between actual cash value and replacement cost?

Actual cash value is what your car is worth at the time of the crash, accounting for age and wear. Replacement cost is what it would cost to buy a similar car new. Car insurance pays actual cash value, not replacement cost. A five-year-old car worth $15,000 will be paid at $15,000, not at the price of a new version of that model.
