Collision auto insurance: what it covers, when it's required, and when to drop it
Last reviewed September 21, 20264 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team
Collision insurance pays to repair or replace your vehicle when it is damaged in a crash, regardless of who caused it. Rear-end someone in stop-and-go traffic, slide into a guardrail on an icy curve, or get sideswiped by a driver who flees the scene: collision coverage handles the repair bill for your own car in all three scenarios.
What collision coverage pays for
The payout process works in two steps. First, you pay your deductible, the fixed amount you agreed to absorb when you bought the policy. Then your insurer covers the remaining cost, up to the vehicle's actual cash value (ACV). ACV is what the car would sell for on the open market the day before the accident, which means depreciation reduces it over time. If repair costs exceed ACV, the insurer typically declares the vehicle a total loss and pays the ACV instead.
Events collision coverage generally includes:
- Crashes with another vehicle, whether you are at fault or not
- Single-car accidents (hitting a tree, a pole, a ditch, or a fence)
- Rollovers
- Accidents with a hit-and-run driver, where the other party cannot pay
One detail that surprises many drivers: collision coverage applies regardless of fault determination. You do not have to wait for the other driver's liability insurer to accept responsibility before filing a claim under your own collision policy.
How a collision claim is paid
Actual cash value is what your car would sell for the day before the crash. Depreciation lowers it over time.
What collision does not cover
Collision has a clear boundary: it responds when your car physically strikes something or something strikes it. Damage that happens without a collision goes through comprehensive coverage instead. Comprehensive handles theft, fire, flood, hail, fallen trees, and animal strikes. Collision handles none of those.
Collision also does not pay for:
- Damage to the other driver's vehicle (covered by your property damage liability)
- Medical bills for you or your passengers (covered by personal injury protection or medical payments coverage, where you carry it)
- Personal property inside the car
This boundary matters when you consider what state minimum liability policies actually buy you. California's Department of Insurance, implementing SB 1107, raised the state's minimum property damage liability requirement to $15,000 per accident effective January 1, 2025. That floor protects other people's cars from damage you cause, not yours. Drivers who want their own vehicle covered after a crash need collision coverage on top of any liability limit.
Collision coverage: what is in and what is out
Covers
- Crashes with another vehicle, at fault or not
- Single-car accidents: hitting a tree, pole, ditch, or fence
- Rollovers
- Hit-and-run accidents where the other driver cannot pay
Does not cover
- Damage to the other driver's car (that is property damage liability)
- Medical bills for you or your passengers
- Personal property inside the car
- Theft, fire, flood, hail, or animal strikes (those go through comprehensive coverage)
Damage without a collision, like theft or hail, belongs to comprehensive coverage, a separate policy.
When you need collision, and when you might not
Collision coverage is generally required by lenders. If you are financing or leasing your vehicle, the lienholder has a financial interest in the car and will require both collision and comprehensive coverage until the loan or lease ends. That requirement is written into most financing agreements and is not negotiable.
For vehicles you own outright, the decision is a cost-benefit calculation. The central question is whether the coverage's cost over time exceeds the maximum you would ever collect on a claim. If your car's ACV has fallen low enough that a claim payout, minus your deductible, would be negligible, the math may argue against paying premiums.
One data point worth keeping in mind: NHTSA's 2024 crash data shows that property-damage-only crashes accounted for 72% of all police-reported crashes in the US, totaling 4,467,244 of 6,180,241 crashes that year. Most crashes result in property damage, not injury. That frequency is a real argument for keeping collision on any vehicle you would genuinely struggle to replace out of pocket.
A rough framework for the decision:
| Situation | Generally worth keeping? |
|---|---|
| Financing or leasing | Yes, lender requires it |
| Car has high market value | Yes |
| Low ACV, owned outright | Evaluate: weigh annual premium plus deductible against ACV |
| You can absorb a total loss | May be reasonable to drop |
| High-mileage, frequent urban driving | Yes |
Most U.S. crashes result in property damage, not injuries. Collision coverage pays for repairs to your own car.
How your deductible and risk profile shape the cost
Collision premiums are not a fixed number. They vary based on your deductible choice, your driving record, where you live, and the vehicle itself. No verified national average exists that applies cleanly to any individual, so understanding the factors that move the number is more useful than any figure pulled from a general source.
Deductible: The amount you agree to pay before insurance contributes. A higher deductible lowers your premium because you absorb more of the first-dollar risk. A lower deductible reduces your out-of-pocket exposure per claim but raises your ongoing premium. The right deductible is the highest amount you could realistically pay on short notice without financial strain.
Driving record: At-fault accidents and moving violations signal elevated risk and generally raise your rate.
Location: Dense urban areas with heavier traffic, higher labor costs for auto repair, and more uninsured drivers tend to carry higher collision rates than rural areas.
Vehicle: Repair costs vary substantially by make and model. Vehicles with expensive parts, limited independent repair options, or advanced driver-assistance systems that require recalibration after minor impacts cost more to insure.
Annual mileage: More time on the road means more exposure. Carriers typically ask for estimated annual mileage and factor it into the premium.
When you shop collision coverage, ask each carrier how they calculate actual cash value at claim time and whether they offer agreed value or replacement cost endorsements for newer vehicles. Those optional add-ons can change what you receive if the car is totaled, and the difference is worth understanding before a claim happens.

What is collision coverage on a car insurance policy?
Collision coverage is the part of a car insurance policy that pays for damage to your own car after a crash.
It applies when your car hits another vehicle or an object, and when your car flips over. You choose a deductible, which is the share of the repair bill you pay before the insurer pays the rest. Collision is optional in most cases, but a lender or a leasing company often requires it while you still owe money on the car.
Do I need collision coverage if my car is paid off?
It depends.
Once the loan is paid off, no lender can require collision coverage, so the choice is yours. Ask yourself one question: if your car were wrecked tomorrow, could you replace it out of pocket without hurting your household? If the answer is no, collision still does real work. If the car is old and worth little, the claim payment may be small, since collision pays based on what the car is worth, not what a new one costs.
What does comprehensive car insurance cover?
Comprehensive covers damage to your car that does not come from a crash with another vehicle or an object.
Think of it as protection from events you cannot steer around. That includes theft, fire, hail, falling tree limbs, flooding, vandalism, and hitting an animal on the road. Broken glass usually falls here too. You pick a deductible, which is the part of the bill you pay before the insurer pays the rest. Comprehensive is optional unless a lender requires it.
Does comprehensive insurance cover a cracked windshield?
Yes.
Glass damage is usually handled under comprehensive, not collision, because a rock or road debris is not a crash. If a stone chips your windshield on the highway, that is a comprehensive claim. Your deductible still applies, which is the share of the bill you pay first. Some states require insurers to offer glass coverage with a lower deductible or none at all, and those rules vary by state. Fixing a small chip early usually costs less than a full replacement.
What happens if a deer runs into my car?
Hitting an animal is normally a comprehensive claim, not a collision claim, even though it feels like a crash.
Comprehensive covers the damage the animal caused to your car, minus your deductible. There is an odd twist: if you swerve to miss the deer and hit a tree or a ditch instead, that becomes a collision claim, because you struck an object. Report the incident to your insurer either way, and take photos of the damage before any repairs begin.
What is the difference between comprehensive and collision insurance?
Both pay for damage to your own car, but they split the world in two.
Collision handles crashes: hitting another vehicle, hitting an object like a pole or a guardrail, or rolling your car over. Comprehensive handles almost everything else: theft, fire, hail, flooding, vandalism, falling branches, and hitting an animal. Each one carries its own deductible, which is the part of the bill you pay before the insurer pays. You can buy them together or, in many cases, separately.
Is a stolen car covered by collision insurance?
No.
Theft falls under comprehensive coverage, not collision. Collision only pays when your car strikes another vehicle or an object, or when it rolls over. If your car is stolen and never found, comprehensive pays what the car was worth at the time it was taken, minus your deductible. If it is recovered with damage, comprehensive covers the repairs. File a police report first, since insurers ask for the report number when they open a theft claim.
Can I buy comprehensive without collision?
It depends on the insurer and on whether you owe money on the car.
Many insurers will sell comprehensive alone, since it covers theft, fire, and weather damage while the car sits parked. Buying collision alone is far less common. If a lender or a leasing company holds the title, it usually requires both, and that rule sits in your loan or lease contract, not in state law. Ask your insurer which pairings it allows before you drop a coverage.
What does an HO-6 condo insurance policy cover?
An HO-6 is the policy written for a condo owner.
It covers the parts of the home you own and the association does not: interior walls, flooring, cabinets, fixtures, and built in features, depending on how your association documents split things. It also covers your belongings, your liability if someone is hurt in your unit, and a place to stay if a covered loss makes your unit unlivable. Many policies add loss assessment coverage for your share of a building claim.
Do I need condo insurance if the building already has a master policy?
Yes.
In almost every case you still need your own policy. The master policy the association buys covers the building shell and shared areas like hallways, the roof, and the lobby. It does not cover what is inside your unit, your belongings, or your personal liability. Read your association bylaws to see where the master policy stops, since the dividing line differs from building to building. An HO-6 policy fills that space. Lenders usually require one before they will finance a condo.
What is loss assessment coverage on a condo policy?
When a covered loss hits the shared parts of a condo building and the master policy does not pay all of it, the association can bill each owner a share.
That bill is called an assessment. Loss assessment coverage is the piece of your HO-6 policy that helps pay your share. It applies to assessments tied to a covered loss, not to routine repairs or normal upkeep. Coverage amounts and rules vary by policy, so check your declarations page.
Does collision coverage pay if I hit a tree?
Yes.
Collision coverage pays to fix or replace your car when it crashes into an object or another vehicle. A tree counts as an object. It also applies if you hit a fence, a pole, or a guardrail, or if your car rolls over. You still pay your deductible first, which is the part of the repair bill you cover. Collision pays for your car damage even when the crash is your fault. It does not pay for the other driver's car.
