When you purchase a vehicle, state laws require you to carry minimum liability insurance. But liability only protects other drivers and their property when an accident is your fault—it pays nothing to repair your own vehicle. If you want protection for your car after a wreck, you need collision insurance.
Whether you are financing a new SUV or deciding whether to drop coverage on an older commuter car, understanding how collision coverage works can save you thousands of dollars in out-of-pocket repairs or unnecessary premiums.
Here is a breakdown of what collision insurance covers, how much it costs, and how to determine whether you actually need it.
What Is Collision Insurance?
Collision insurance is an optional auto insurance policy add-on that pays to repair or replace your vehicle if it is damaged in a crash, regardless of who is at fault.
If your vehicle is damaged in a covered incident, collision coverage pays for repairs up to your vehicle’s actual cash value (ACV), minus your out-of-pocket deductible. If the repair estimate exceeds a certain percentage of the vehicle’s market value (typically 70% to 80%, depending on state guidelines), your insurer will declare the vehicle a total loss and write you a check for its pre-accident market value.
What Does Collision Insurance Cover?
Collision coverage is designed strictly for impact-related damage while your car is in motion or involved in a physical collision.
What’s Covered:
- Accidents with other vehicles: Collisions involving other cars on the road, whether you or the other driver caused the crash.
- Collisions with stationary objects: Backing into a telephone pole, scraping a concrete guardrail, or hitting a mailbox or street sign.
- Single-vehicle rollover accidents: Rolling or flipping your car due to slick road conditions or loss of control.
- Potholes and roadway hazards: Structural, suspension, or wheel damage caused by hitting deep potholes or running into a roadside ditch.
What Isn’t Covered:
- Hitting an animal: Striking a deer or other wildlife falls under comprehensive insurance, not collision.
- Weather and natural disasters: Hail damage, floodwaters, fallen tree limbs, or wind damage are covered exclusively by comprehensive coverage.
- Theft and vandalism: Broken windows, keyed paint, or a stolen vehicle require comprehensive protection.
- Damage to other people’s vehicles: Damage you cause to someone else’s car is paid under your property damage liability.
- Medical bills: Injuries to you or your passengers are handled through Medical Payments (MedPay) or Personal Injury Protection (PIP).
| Coverage Scenario | Collision Insurance | Comprehensive Insurance | Property Damage Liability |
| You rear-end another car (your damage) | Covered | Not Covered | Not Covered |
| You rear-end another car (their damage) | Not Covered | Not Covered | Covered |
| You slide on black ice into a guardrail | Covered | Not Covered | Not Covered |
| A tree branch falls on your hood | Not Covered | Covered | Not Covered |
| You hit a deer on a rural highway | Not Covered | Covered | Not Covered |
| Your car is vandalized or stolen | Not Covered | Covered | Not Covered |
Do You Need Collision Coverage?
Because collision insurance is not mandated by state law, deciding whether to carry it comes down to vehicle financing, car value, and your personal financial buffer.
When Collision Insurance Is Essential:
- You are financing or leasing: Lenders and leasing companies almost universally require you to carry both collision and comprehensive insurance until the loan is paid in full.
- Your car is newer or has high market value: If replacing your car tomorrow would wipe out your emergency fund, collision coverage acts as an essential financial safety net.
- You have a long, congested daily commute: Drivers regularly navigating heavy urban traffic face higher statistical odds of at-fault or multi-car fender benders.
When You Can Consider Dropping It:
- You drive an older, low-value vehicle: As a general insurance rule of thumb, if the annual cost of your collision and comprehensive coverage combined exceeds 10% of your car’s actual cash value, dropping full coverage to liability-only often makes financial sense.
- Your deductible approaches the car’s worth: If your car is worth $2,000 and your deductible is $1,000, the maximum payout you could receive in a total loss is only $1,000. Paying several hundred dollars a year to protect a potential $1,000 payout rarely pencils out.
How Much Does Collision Insurance Cost?
Collision insurance is rarely purchased in isolation; it is typically bundled with comprehensive and liability insurance to create full coverage car insurance.
Adding collision coverage to a baseline liability policy typically brings monthly premiums to roughly $157 to $268 per month, depending on your driver profile and vehicle type.
Choosing the Right Collision Deductible
Your deductible is the amount you agree to pay out-of-pocket before insurance funds kick in. Standard deductibles generally range from $250 to $1,000:
- $250 to $500 Deductible: Lower out-of-pocket expense during an accident, but results in higher ongoing monthly premiums.
- $1,000+ Deductible: Lowers your monthly premium noticeably, but requires having immediate cash reserves ready if you need body repairs.
A practical approach is to select the highest deductible you could comfortably transfer from your savings tomorrow without disrupting your household budget.
When to File a Collision Claim (and When to Pay Cash)
Filing an auto insurance claim isn’t always the right financial move, even when the damage is technically covered. A single at-fault collision claim can trigger an insurance surcharge, raising your rates for three to five years.
You Should File a Claim If:
- You caused an accident resulting in substantial damage that far exceeds your deductible.
- You were involved in a hit-and-run, and the other driver fled the scene.
- The at-fault driver’s insurance is delayed, disputed, or insufficient to cover the full repair cost.
You Should Pay Out-of-Pocket If:
- The repair estimate is less than your deductible (an insurer will not pay anything in this case anyway).
- The repair cost is only slightly higher than your deductible (for example, a $1,200 repair with a $1,000 deductible). In this scenario, saving $200 today could cost you hundreds more in premium increases over the next several years.
Special Consideration: Collision Deductible Waivers (CDW)
In select states, such as California and Massachusetts, drivers can purchase an optional add-on known as a Collision Deductible Waiver (CDW).
If an uninsured or hit-and-run driver damages your vehicle and is determined to be at fault, a CDW waives your out-of-pocket collision deductible entirely, ensuring your car is repaired at zero direct cost to you. If you live in an area with high rates of uninsured motorists, asking your insurance agent about a deductible waiver is a low-cost way to eliminate surprise expenses.
Frequently Asked Questions
Who benefits most from carrying collision coverage?
Drivers with financed or leased vehicles, owners of newer or high-value cars, and individuals who do not have enough liquid savings to replace their daily transportation out-of-pocket benefit the most from collision insurance.
Should I keep collision insurance on a 10-year-old car?
It depends on the car’s current market value. Check Kelley Blue Book or Edmunds for your car’s actual cash value. If the vehicle is worth under $3,000 to $4,000 and your annual insurance premiums for collision are high, switching to liability-only coverage can yield meaningful annual savings.
What is the difference between collision and full coverage?
Collision is a single component of a policy. “Full coverage” is an industry term that generally refers to a policy bundling liability, collision, and comprehensive insurance together for complete bumper-to-bumper protection.
Will collision insurance pay for flood or water damage?
No. Water damage, flash floods, and weather-related destruction are covered exclusively under comprehensive insurance.
How much collision coverage should I buy?
Unlike liability insurance, you do not select a dollar limit for collision coverage. Your policy automatically caps its payout at your vehicle’s actual cash value minus your chosen deductible.
