Collision and comprehensive coverage are the two parts of an auto policy that pay to fix or replace your own vehicle. Collision handles impacts: your car hitting another car, a guardrail, a pole, or the ground in a rollover. Comprehensive handles almost everything else that damages a parked or driven car without a traffic impact, including theft, vandalism, hail, flood, fire, and animal strikes. Neither is required by any state, but if you financed or leased the car, your lender almost certainly requires both.
What Collision Covers
Collision pays when your vehicle hits something or something hits your vehicle, whether it’s moving or parked. The classic case is a two-car crash, and fault doesn’t matter to your own insurer. You can file under collision whether you caused the accident, the other driver did, or liability is still being sorted out. That’s the point of carrying it: repairs can start before anyone’s insurer accepts blame.
Striking a stationary object is covered the same way, as are single-vehicle rollovers and hit-and-run damage to a parked car in a lot. Pothole damage severe enough to bend a rim or wreck your suspension falls under collision too, though gradual tire wear from rough roads does not.1Insurance Information Institute. Does My Auto Insurance Cover Damage Caused by Potholes?
What Comprehensive Covers
Comprehensive is sometimes labeled “other than collision” in policy documents, and the list of triggers is wide. Theft of the whole vehicle, a broken window to steal what’s inside, keying, graffiti, and other vandalism all fall here. So do weather events: hail, flood, tornado damage, wildfire, and limbs falling in a storm. Fire from an electrical fault under your own hood counts.
Animal contact is the one that catches people out. Hitting a deer is a comprehensive claim, not a collision claim, even though the physics look the same. A bird cracking your windshield is comprehensive too. The distinction isn’t academic, because comprehensive deductibles are often lower than collision deductibles on the same policy.
Glass Claims
Cracked windshields are among the most common comprehensive claims, and the deductible rules are gentler than most drivers assume. If a chip can be repaired instead of replaced, many insurers waive the deductible outright. A few states go further and require zero-deductible full replacement; Florida and Kentucky are among them, while states like Connecticut and New York allow insurers to offer optional glass endorsements that eliminate the deductible for a small added premium.2Policygenius.

Who’s Actually Required to Carry These
No state requires collision or comprehensive. State mandates cover liability insurance, which pays for damage you cause to other people and their property, not damage to your own car.3Insurance Information Institute. Automobile Financial Responsibility Laws By State The pressure to carry physical damage coverage comes from the lender, not the government.
When you finance or lease, the lender holds a lien on the title and the car is their collateral. Loan agreements almost universally require you to maintain both collision and comprehensive until the loan is paid off. If your coverage lapses, the lender can buy a policy on your behalf and add the premium to your monthly payment. This force-placed insurance is usually far more expensive than what you’d pay shopping on your own, and it typically protects only the lender’s interest in the car, not yours.4Consumer Financial Protection Bureau. 12 CFR 1024.37 – Force-Placed Insurance If you get a notice that force-placement is coming, reinstating your own policy quickly is worth the trouble.
How Payouts Are Calculated
When you file either kind of claim, the insurer doesn’t pay what you bought the car for and doesn’t pay what a new replacement costs. It pays actual cash value: what your car would have sold for in your local market right before the loss.
Actual Cash Value
Insurers use third-party valuation tools that pull data on comparable vehicles and factor in year, make, model, trim, mileage, condition, options, and local prices.5Kelley Blue Book. Actual Cash Value: How It Works for Car Insurance This isn’t a straight-line depreciation off the sticker price. A clean, low-mileage car in a market where that model is in demand can land above a simple depreciation formula; a tired, high-mileage car can land below it. The payout tracks what real buyers near you are paying for similar cars.
Your Deductible
Before the insurer pays, you cover your deductible. It’s a flat dollar amount you pick when you buy the policy, typically $250, $500, $1,000, or $2,000, with $500 the most common choice. A higher deductible lowers your premium but means more out of pocket each time you file. If a repair runs $3,200 and your deductible is $500, the insurer pays $2,700. If the repair costs less than your deductible, there’s no claim to make.
When the Car Is Totaled
If repair costs climb high enough compared with the car’s value, the insurer declares a total loss rather than paying to fix it. Some states set a fixed percentage threshold; others use a formula comparing repair cost to ACV minus salvage value. Thresholds range from about 60 percent in some states up to 100 percent in others, including Colorado and Texas.
On a total loss, you get ACV minus your deductible. If there’s a lienholder, the lender is paid first and you get whatever remains. You can usually keep the totaled car, but the insurer subtracts the salvage value from your check, and the vehicle has to be inspected, repaired, and retitled as salvage before it can go back on the road.5Kelley Blue Book. Actual Cash Value: How It Works for Car Insurance
If the Valuation Looks Too Low
You don’t have to accept the first number the adjuster quotes. If comparable vehicles are selling for more in your area, bring that evidence: dealer asking prices and recent listings for the same year, trim, and mileage range are your strongest material.
Most auto policies include an appraisal clause. You invoke it in writing, hire your own appraiser, and the insurer hires one too. The two try to agree on a value, and if they can’t, a neutral umpire breaks the tie. The result is typically binding. You pay your appraiser and split the umpire’s fee with the insurer. For a dispute worth a few thousand dollars, it’s usually faster and cheaper than suing.
Filing a complaint with your state’s department of insurance is a parallel option at no cost. A state investigator reviews whether the valuation was reasonable, and the insurer sometimes revises its offer before the review is even finished.
The Gap Problem on Financed Cars
Here’s the scenario that catches people off guard. You owe $22,000 on your loan. A hailstorm totals the car. The ACV payout is $17,000, minus a $500 deductible, so you get $16,500. The lender takes all of it, and you still owe $5,500 on a car you can’t drive. Gap insurance exists to cover that shortfall. It pays the difference between the collision or comprehensive payout and the balance of your loan or lease.
Gap is sold by auto insurers as an add-on, by dealerships at point of sale, and sometimes by lenders directly. Buying it through your auto insurer is almost always the cheapest route. Some carriers sell a variant called loan or lease payoff coverage that caps its payout at a percentage of ACV, often around 25 percent, rather than covering the whole gap no matter the size. If you’re deeply upside down, check for a cap. Gap typically requires both collision and comprehensive on the policy, and it doesn’t cover past-due payments, late fees, or lease-end mileage charges.
Getting Your Deductible Back: Subrogation
If another driver caused the crash and you filed under your own collision coverage to get repairs moving, your insurer pursues the at-fault driver’s carrier to recover what it paid. That process is called subrogation, and your deductible rides along with it. If the recovery succeeds in full, you get a reimbursement check for the deductible you fronted.
It takes months, and it isn’t guaranteed. If the other driver was uninsured or fault is contested, recovery can be partial or nothing. In clean rear-end cases where the other insurer accepts liability, deductible recovery is common. You don’t need to do anything beyond filing your claim; your insurer runs the pursuit.
Diminished Value After Repairs
Even a flawlessly repaired car loses resale value because buyers discount vehicles with accident histories. That loss is called diminished value, and in most states you can claim it against the at-fault driver’s insurer. Nearly every state except Michigan allows some form of diminished value claim when the other driver was at fault.
You generally can’t file one against your own insurer, so if you were at fault or it was a single-vehicle incident, this remedy isn’t available. Proving the loss falls on you, usually through an independent appraisal comparing pre-accident and post-repair values. Adjusters resist these claims, so documentation matters.
What These Coverages Don’t Pay For
The exclusions are where policyholders get surprised. Keep these in mind before assuming a loss is covered.
- Mechanical breakdowns. A blown engine, failed transmission, or dead alternator is a maintenance issue, not an insurable loss. Extended warranties and mechanical breakdown insurance are separate products.
- Wear and tear. Thin brake pads, old tires, faded paint, and dying batteries are expected deterioration. Insurance pays for sudden events, not slow decline.
- Racing. Damage during any organized speed contest or track event isn’t covered by a personal policy. Track-day insurance is specialized and separate.
- Intentional damage. Deliberately damaging your car to collect isn’t just excluded, it’s fraud with criminal penalties.
- Personal items inside the car. A stolen laptop, phone, or camera is a homeowner’s or renter’s claim, not an auto claim.
- Aftermarket modifications. Custom wheels, performance exhaust, and upgraded stereos may be covered only up to a small cap under a standard policy. If you’ve put serious money into modifications, ask about custom equipment coverage; without it, a total loss pays the factory value.
Rideshare and Delivery Driving
If you drive for a rideshare or delivery platform, your personal collision and comprehensive likely stop applying the moment you log into the app. Standard personal auto policies exclude vehicles used as a “public livery or conveyance,” and insurers read that to include every phase of gig driving, from waiting for a request to carrying a passenger or delivering food.
Uber and Lyft carry their own insurance, but it doesn’t fully protect your vehicle at every stage. While you’re waiting for a ride request with the app on, the platform’s own-car coverage is minimal or nonexistent. Once you accept a ride and are heading to the passenger, platform coverage increases but often carries a deductible as high as $2,500. A rideshare endorsement on your personal policy fills these gaps and can bring the effective deductible down to your usual number.
Not disclosing gig work to your insurer is riskier than just a coverage gap. If you file a claim and the insurer finds out you were logged into a rideshare app, they can deny the claim and cancel the policy.
Rental Reimbursement
Collision and comprehensive pay to fix the car; they don’t pay for a rental while it sits in the shop. Rental reimbursement is a separate add-on. Without it, you’re covering rental costs out of pocket, which stretches into weeks when parts are delayed. Typical limits run $40 to $70 per day for 30 or 45 days, depending on policy and state. The add-on usually costs a few dollars a month and is one of the better values on an auto policy. You generally need both collision and comprehensive on the same vehicle to qualify.
When to Drop Collision or Comprehensive
Once the car is paid off, both coverages become optional, and at some point the math stops working. A common rule of thumb: if the car’s market value is less than ten times your annual premium for these coverages, you’re spending more than the policy is likely to pay out. Paying $600 a year to insure a $4,000 car means a lot of premium chasing a small potential payout, especially after the deductible.
Dropping collision first usually makes sense because it costs more. Comprehensive is cheaper and covers high-impact events like theft and weather that are harder to self-insure against, which is why many drivers keep it long after they drop collision. Before cutting either, make sure you have enough savings to replace the car outright. If losing the vehicle would mean losing your way to work, the premium may still be worth paying even when the formula says otherwise.
