Collision Coverage for Auto Insurance: What It Covers and How It Differs

The Short Answer

Collision coverage is the part of a US auto insurance policy that pays to repair or replace your own vehicle after it hits another vehicle or an object, or after it rolls over. It generally applies no matter who caused the crash. You pay a deductible first, and the insurer pays the rest of the covered repair cost, up to the vehicle's actual cash value. Collision is usually optional under state law, but a lender or leasing company will typically require it if you finance or lease the car. The exact terms depend on your policy and your state, so the policy declarations page and contract wording control what applies to you.

What Collision Coverage Typically Pays For

Collision is first-party physical damage coverage, which means it protects the car listed on your policy, not other people or their property. Common covered situations include:

Hitting another vehicle, whether moving or parked; Being hit by another vehicle, especially when the other driver is unidentified, uninsured or disputing fault; Striking a fixed object such as a guardrail, pole, fence, wall, curb or tree; A single-vehicle rollover; Damage from hitting a pothole or road debris, depending on how the policy defines a collision

Coverage usually extends to a car you are driving with permission, and some policies extend it to rental cars, but these extensions vary by insurer and policy form.

What Collision Coverage Does Not Pay For

Injuries to you, your passengers or anyone else; those fall under medical payments, personal injury protection, bodily injury liability or uninsured motorist coverage; Damage you cause to other people's vehicles or property; that is property damage liability; Theft, vandalism, fire, flood, hail, falling objects and, in most policies, hitting an animal; those are typically comprehensive claims; Mechanical breakdown, wear and tear, rust or maintenance problems; Personal belongings inside the car, which are often handled through homeowners or renters insurance; Rental car costs while your car is in the shop, unless you add rental reimbursement coverage

How Collision Differs From Other Coverages

Coverage | Protects | Typical events | Usually required? Collision | Your own vehicle | Crashes with vehicles or objects, rollovers | Optional by law; often required by lenders and lessors; Comprehensive | Your own vehicle | Theft, vandalism, weather, fire, flood, animal strikes | Optional by law; often required by lenders and lessors; Liability (bodily injury and property damage) | Other people and their property | Damage or injuries you cause to others | Required in nearly every state; Uninsured/underinsured motorist property damage | Your own vehicle, in some states | Damage caused by an uninsured or underinsured driver | Varies by state

Collision and comprehensive are often sold together and loosely called full coverage, although that phrase is a marketing shorthand rather than a defined policy type. The practical distinction is the cause of damage: impact with a vehicle or object usually points to collision, while most other physical damage points to comprehensive.

How the Deductible Works

The deductible is the amount you pay toward each covered collision claim before the insurer pays. You choose it when buying the policy. A higher deductible generally lowers your premium but raises your out-of-pocket cost per claim; a lower deductible does the opposite. If a repair costs less than or about the same as your deductible, filing a claim may not be worthwhile.

When another driver is at fault, your insurer may pay for your repairs and then seek reimbursement from the at-fault driver's insurer, a process called subrogation. If that recovery succeeds, your insurer often refunds your deductible, in full or in part. Some insurers and some states offer deductible waivers in certain at-fault-of-another-driver situations, but availability varies.

Actual Cash Value and Total Losses

Collision payouts are normally capped at the vehicle's actual cash value, meaning its market value just before the accident, accounting for age, mileage, condition and depreciation. It is not the price you paid or the cost of a new replacement.

If repair costs approach or exceed that value, the insurer may declare the car a total loss and pay the actual cash value minus your deductible. If you owe more on a loan or lease than the car is worth, that difference is not covered by collision. Gap insurance, offered by many insurers, lenders and dealers, is designed to cover that shortfall. Some policies also offer new car replacement or better car replacement options with their own conditions.

Using Collision When the Other Driver Is at Fault

If someone else causes the crash, you can usually file with their property damage liability coverage instead of your own policy, which avoids your deductible. Going through your own collision coverage can still make sense when fault is disputed, the other insurer is slow to respond, or the other driver's limits are too low to cover your damage. Your insurer then handles recovery from the other party.

Is Collision Coverage Required?

State laws generally require liability coverage, not collision. Collision becomes effectively mandatory when your vehicle is financed or leased, because the lender or lessor has a financial interest in the car and typically requires both collision and comprehensive, sometimes with a maximum allowed deductible. Once the car is paid off, keeping collision is your choice.

When Collision Coverage Makes Sense

Deciding whether to carry collision comes down to whether you could absorb the cost of repairing or replacing the car yourself. Factors worth weighing:

Vehicle value: the closer the car's actual cash value gets to your deductible, the less collision can ever pay out; Premium versus potential payout: compare the yearly cost of collision with what you would realistically receive after a total loss; Savings: if losing the car would leave you without transportation you could not replace, the coverage has more value; Driving exposure: commuting distance, traffic density, parking situation and who else drives the car all affect the likelihood of a claim; Loan or lease terms, which may leave no choice

A common approach is to keep collision on newer or higher-value vehicles and consider dropping it on older, low-value cars once the premium becomes large relative to what a claim could return.

Filing a Collision Claim

Make sure everyone is safe and follow your state's rules for reporting the accident to police; Exchange information with other drivers and record the scene with photos; Notify your insurer promptly, as policies generally require timely reporting; Have the damage inspected by the insurer's adjuster or an approved shop, and get repair estimates if requested; Pay your deductible to the repair shop, or have it subtracted from the settlement; Ask whether subrogation is being pursued if another driver was at fault, so you know whether to expect a deductible refund

An at-fault collision claim may affect your future premiums, depending on your insurer and state rules. Claims where you were not at fault are treated differently in many states, but the rules vary.

Key Takeaways

Collision coverage repairs or replaces your own car after a crash or rollover, regardless of fault, minus your deductible and up to the car's actual cash value. It does not cover injuries, damage to others, theft or weather events, which belong to other parts of a policy. It is usually optional unless a lender or lessor requires it, and its value depends mainly on what your car is worth and how well you could cover a loss on your own.
