Collision coverage explained

What collision coverage pays for, how the deductible and actual cash value limit your payout, and how to decide whether to keep it on an older car.

4AutoInsurance · Published October 4, 2026

Collision coverage pays to repair or replace your own car after it hits another vehicle or an object, or rolls over, minus your deductible. It applies whether or not the crash was your fault, which makes it the coverage that gets you back on the road quickly when you caused the accident or when the other driver's insurer is slow. It is optional under state law but usually required by a lender or leasing company.

What collision covers

Collision coverage pays for physical damage to your insured car caused by:

  • Hitting another vehicle, moving or parked.
  • Being hit by another vehicle, if you choose to claim on your own policy.
  • Hitting an object such as a tree, guardrail, pole, curb or building.
  • Rolling over.
  • Pothole damage. The Insurance Information Institute lists potholes and rollovers among losses collision covers (III).

It generally also applies to a car you rent or borrow for personal use in the U.S., subject to your policy terms and the rental agreement.

What collision does not cover

Damage Covered by collision? Where to look instead
Theft, fire, flood, hail, vandalism, falling trees No Comprehensive
Hitting a deer or other animal Usually no Comprehensive in most policies
Broken windshield from a rock Usually no Comprehensive or glass coverage
Mechanical breakdown, wear and tear No Warranty or mechanical breakdown coverage
The other driver's car No Your liability coverage
Your injuries No PIP, MedPay or health insurance

The animal-strike rule surprises people: hitting a deer is normally a comprehensive claim, but swerving to miss it and hitting a tree is a collision claim. Policy wording controls, so check yours.

How the payout is calculated

Two numbers limit every collision payout: your deductible and the car's value.

Repairable car: the insurer pays the repair cost minus your deductible. If repairs cost $4,800 and your deductible is $500, you get $4,300, often paid directly to the shop. If the shop finds hidden damage after taking the car apart, it submits a supplement and the insurer pays the added cost, still minus a single deductible.

Totaled car: when repair costs approach or exceed the car's value, the insurer declares a total loss and pays its actual cash value, the market value just before the crash, minus your deductible. It does not pay what you owe on the loan or what you paid for the car. See what happens when your car is totaled; the total loss calculator can estimate your payout.

Collision has no separate dollar limit on most personal policies; the car's actual cash value is the effective ceiling.

When the other driver was at fault

You have two options when someone else hits you:

  1. Claim against the other driver's liability insurance. You pay no deductible, but you wait for that insurer to accept fault, and it may dispute the damage.
  2. Claim on your own collision coverage. Your insurer pays you promptly, minus the deductible, then pursues the at-fault driver's insurer for reimbursement. If it recovers, you usually get your deductible back, in full or in proportion to the recovery. See subrogation explained: how your insurer recovers your deductible.

Some policies include a collision deductible waiver that drops your deductible when an identified, at-fault uninsured driver hits you; see collision deductible waiver. Availability varies by insurer and state. In some states, uninsured motorist property damage coverage is another route for damage caused by an uninsured driver.

Filing a collision claim

  1. Make sure everyone is safe, call police if there are injuries or significant damage, and photograph the scene and both vehicles.
  2. Report the claim to your insurer promptly by app, phone or online.
  3. Get a repair estimate. Your insurer may inspect the car, ask for photos, or suggest a shop in its network; many states' laws protect your right to choose your own shop.
  4. Pay your deductible to the shop when you pick up the car, unless the insurer has collected it from the other driver's insurer first.
  5. Keep receipts for towing and storage, which are often reimbursed as part of a covered claim; ask your adjuster.

A worked example

This example is hypothetical. Your car is worth $14,000. You carry collision with a $1,000 deductible. You slide on ice into a stone wall, and the body shop estimates $6,200 in repairs.

  • Your insurer pays $6,200 - $1,000 = $5,200.
  • You pay the shop $1,000.
  • Because the crash was single-vehicle and you were responsible, it is likely to count as an at-fault claim and may affect your premium at renewal, depending on your insurer's rules and your state.

If the estimate had been $12,500, the insurer might declare the car a total loss instead, paying about $14,000 - $1,000 = $13,000, with the insurer taking the damaged car.

Choosing a deductible

A higher deductible lowers your premium but raises what you pay per claim. The right choice depends on your emergency savings and how often you claim. Common choices are $500 and $1,000. Run your premium quotes through the deductible break-even calculator to see how many claim-free years it takes for the higher deductible to pay off.

When to drop collision

Collision is usually the most expensive physical damage coverage, so it is the first one drivers consider dropping on an older, paid-off car. Ask:

  • Could you replace or repair the car from savings without hardship?
  • Is the annual collision premium a large share of the car's value minus the deductible?
  • Do you still owe money on it? If so, the lender requires it.

Many drivers keep comprehensive after dropping collision, because it is often cheaper and covers theft and weather. The Should I drop full coverage? calculator compares the cost with the most you could collect. For how collision fits into a broader package, see what full coverage car insurance actually means.

Key takeaways

  • Collision pays for damage to your car from hitting a vehicle or object, or rolling over, regardless of fault.
  • Payouts are repair cost or actual cash value, minus your deductible; collision does not pay your loan balance.
  • Animal strikes, theft and weather are usually comprehensive claims, not collision.
  • When another driver is at fault, your collision coverage can pay first and recover your deductible through subrogation.
  • On an older, paid-off car, compare the annual collision premium with the most it could ever pay.

Terms used in this guide

Collision coverage Pays to repair or replace your own car after it hits another vehicle or object, or rolls over, regardless of fault, minus your deductible. Deductible The amount you pay toward a covered loss before your insurer pays the rest, set per claim for coverages like collision and comprehensive. Actual cash value What a car was worth just before a loss — replacement cost minus depreciation — and the basis of most total-loss payouts. Total loss A car so badly damaged that repairs would cost more than it is worth, or more than a state threshold, so the insurer pays its value instead. Subrogation An insurer's right, after paying your claim, to recover that money from the party who caused the loss, often getting your deductible back too. Collision deductible waiver An option that pays or waives your collision deductible when an identified uninsured driver is at fault for damaging your car.
