What Is Collision Coverage and How Does It Work?
Collision coverage is an optional auto insurance coverage that pays to repair or replace your vehicle when it's damaged in a collision — regardless of who is at fault. Whether you rear-end another car, sideswipe a guardrail, or roll your vehicle, this coverage steps in to cover the cost of getting your car back on the road.
Here's what collision coverage specifically pays for:
| Covered Scenario | Example |
|---|---|
| Collision with another vehicle | You rear-end someone at a stoplight |
| Impact with a stationary object | You back into a concrete pillar or fence post |
| Single-vehicle accident | You slide off an icy road into a ditch |
| Rollover accident | Your vehicle tips or rolls over |
| Pothole damage | Your wheel and suspension are damaged by a deep pothole |
How the claims process works:
- You file a claim with your insurer after a covered incident
- An adjuster assesses the damage to your vehicle
- You pay your chosen deductible (e.g., $500)
- Your insurer covers the remaining repair costs — up to the vehicle's actual cash value (ACV)
- If the car is totaled, you receive the ACV minus your deductible
It's worth noting that collision coverage does not cover medical bills, injuries to others, theft, weather damage, or animal strikes — those fall under other parts of your policy. If you're concerned about a gap between your ACV payout and your loan balance, gap insurance may be worth considering.
Collision Coverage vs. Comprehensive Coverage
One of the most common sources of confusion is the difference between collision and comprehensive coverage. Both are physical damage coverages — but they protect against entirely different types of events.
Which costs more? Collision coverage typically carries a higher premium than comprehensive because accidents directly tied to driving behavior are far more frequent than theft or weather events. Together, these two coverages form what's commonly called "full coverage car insurance."
Both coverages use separate, independently chosen deductibles. You might set your collision deductible at $1,000 and your comprehensive deductible at $500 — it all depends on your financial situation and risk tolerance.

Collision Coverage Deductibles & When It's Required
How Deductibles Work
Your deductible is the amount you agree to pay out of pocket before your insurance kicks in on a claim. Choosing the right deductible is one of the biggest decisions when setting up your collision coverage.
| Deductible Amount | Effect on Premium | Best For |
|---|---|---|
| $250 | Highest monthly premium | Drivers with limited savings |
| $500 | Moderate premium | Most drivers — balanced option |
| $1,000 | Lower monthly premium | Drivers with a healthy emergency fund |
| $1,500–$2,000 | Lowest premium | Very safe drivers, infrequent drivers |
The most popular deductible amounts range from $500 to $1,000. A higher deductible lowers your monthly premium, but means you pay more when a claim occurs. For a detailed breakdown of how to choose wisely, see our guide on car insurance deductibles.
When Lenders and Lease Companies Require It
No U.S. state legally requires collision coverage — but your lender or lease company almost certainly does. Here's why: when you finance or lease a vehicle, the lender retains a financial interest in the car as collateral. If it's damaged and you're not insured, their investment is at risk.
- Auto loan requirement: Collision (and comprehensive) coverage is required for the full duration of your loan term
- Lease requirement: All leased vehicles require both coverages for the entire lease period
- Consequence of dropping it early: Your lender can purchase "force-placed insurance" on your behalf — at a much higher cost to you — and it may even trigger loan default
Once the loan is paid off and you hold the title free and clear, the choice to keep or drop collision is entirely yours.
When to Drop Collision Coverage — The 10% Rule
How the 10% Rule Works
This is arguably the most important financial formula for car owners with older paid-off vehicles. The 10% rule states: if your annual collision premium costs 10% or more of your vehicle's actual cash value, it's likely not worth keeping.
Here's the math:
Car's ACV × 10% = Maximum annual premium that makes sense
| Car Value (ACV) | 10% Threshold | Drop Coverage If Annual Premium Exceeds |
|---|---|---|
| $3,000 | $300 | $300/year |
| $5,000 | $500 | $500/year |
| $8,000 | $800 | $800/year |
| $12,000 | $1,200 | $1,200/year |
Example: Your 2014 sedan has an ACV of $4,500. Your collision premium is $520/year and your deductible is $1,000. Your maximum realistic insurance payout would only be $3,500 ($4,500 ACV minus $1,000 deductible). At $520/year, you'd pay $2,600 in premiums over 5 years just to protect a $3,500 maximum payout. The math doesn't add up.
Other Signs It's Time to Drop Collision
Dropping collision on an older vehicle that no longer justifies the cost can save you hundreds per year. If you're considering other ways to reduce costs, comparing car insurance quotes from multiple providers is one of the fastest ways to find savings.
What Affects the Cost of Collision Coverage?
Several factors determine how much you'll pay for collision insurance:
- Your driving record: At-fault accidents can raise rates by 35–45%; a clean record keeps premiums low
- Your deductible: Higher deductibles = lower premiums
- Vehicle type and age: Newer, more expensive cars cost more to insure under collision
- Your location: Urban drivers pay significantly more than rural drivers due to higher accident frequency
- Your age and gender: Younger drivers, especially teens, pay substantially more
- Your credit score: In most states, poor credit can raise your premium considerably
Nationally, full coverage auto insurance (which includes collision) averaged around $2,144 per year in 2025 — but collision itself typically represents roughly 25–40% of that total depending on your deductible and profile.
Frequently Asked Questions
What exactly does collision coverage pay for?
Collision coverage pays for damage to your own vehicle when it's involved in a collision with another vehicle, a stationary object (like a tree, fence, or guardrail), or when it rolls over. It also covers pothole damage in many cases. The payout is your car's actual cash value minus your deductible — it does not cover medical expenses or damage to another person's vehicle.
Is collision coverage the same as full coverage?
No. "Full coverage" is an informal term that typically refers to a combination of liability, collision, and comprehensive insurance. Collision is just one piece of that package. You can technically carry liability-only insurance without collision, or you can add comprehensive without collision — though most lenders require both. Learn more in our full coverage car insurance guide.
How do I know if my deductible is set correctly for collision?
The right deductible depends on your savings and how much risk you're comfortable with. A $500 deductible is the most common choice and offers a good balance between premium savings and out-of-pocket exposure. If you have a solid emergency fund of $1,000 or more, raising your deductible to $1,000 can lower your premium meaningfully. Our car insurance deductibles guide can walk you through the decision.
What happens if I drop collision coverage and then get into an accident?
If you drop collision and are involved in an accident that is your fault (or a single-car incident), you will be responsible for 100% of your vehicle's repair or replacement costs out of pocket. If another driver is at fault and has liability insurance, their property damage liability coverage may pay for your repairs — but this isn't guaranteed, especially if they're underinsured.
Will an at-fault accident raise my rates after filing a collision claim?
Yes, filing a collision claim after an at-fault accident typically raises your rates. On average, an at-fault accident can increase your premium by 43% or more and stay on your record for 3 to 5 years. Some insurers offer accident forgiveness programs that protect you from a rate hike after your first accident. It's worth asking your insurer if this option is available to you.
