Collision vs Comprehensive: What Each Coverage Actually Pays
Direct answer
Collision pays when your covered auto strikes another vehicle or object or overturns. Comprehensive, called Other than Collision on the standard policy, pays for theft, fire, vandalism, hail, flood, falling objects, and contact with a bird or animal. They are two separate coverages, each with its own deductible, and most lenders and lessors require both. Neither coverage pays for normal wear, mechanical breakdown, or losses that fall under liability.12
The quick answer
- Collision responds to impact with another vehicle or object and to upset (rollover) of your covered auto.1
- Comprehensive responds to losses listed as Other than Collision perils: fire, theft, windstorm, hail, flood, vandalism, falling objects, and contact with a bird or animal.1
- Deer strike is comprehensive, not collision, even though the name sounds otherwise.3
- Neither pays for wear and tear or mechanical breakdown.5
Event-by-event matrix
Each row below cites the policy form or primary explainer that controls the classification. For the definition of each coverage on its own, see our collision coverage and comprehensive coverage guides.
| Event | Collision pays? | Comprehensive pays? | Neither? | Why |
|---|---|---|---|---|
| You hit another vehicle | Yes | No | No | Impact with another vehicle is the textbook collision event under ISO PP 00 01 Part D.1 |
| You hit a guardrail or other fixed object | Yes | No | No | ISO defines collision as impact of your covered auto with another vehicle or object. A guardrail is an object.1 |
| Single-vehicle rollover | Yes | No | No | Upset of your covered auto is explicitly collision under ISO PP 00 01 Part D, regardless of whether anything else was hit.1 |
| Entire car stolen | No | Yes | No | Theft is listed as a comprehensive peril under ISO PP 00 01 Part D (Other than Collision).1 |
| Hail damages the body and glass | No | Yes | No | Hail is listed as a comprehensive peril under ISO PP 00 01 Part D.1 |
| Flood submerges the vehicle | No | Yes | No | Flood damage to a vehicle is covered under comprehensive. A homeowners or flood policy does not cover the car itself.4 |
| Vandalism (keyed paint, broken window) | No | Yes | No | Vandalism is specifically enumerated as a comprehensive peril under ISO PP 00 01 Part D.1 |
| Falling tree crushes a parked car | No | Yes | No | Falling objects are a comprehensive peril under ISO PP 00 01 Part D. The car does not have to be moving.1 |
| Deer strike while driving | No | Yes | No | III and ISO treat contact with a bird or animal as a comprehensive (other than collision) loss, not as a collision loss. The term is a point of frequent confusion for consumers.3 |
| Fire damages the vehicle | No | Yes | No | Fire is enumerated as a comprehensive peril under ISO PP 00 01 Part D.1 |
| Flying rock cracks the windshield | No | Yes | No | Glass damage from a flying object is comprehensive. Some states and some carriers offer a zero-deductible glass option so the deductible does not block the repair.6 |
| Normal wear or mechanical breakdown | No | No | Yes | Neither coverage pays for wear and tear or mechanical breakdown. Mechanical breakdown insurance is a separate optional product.5 |
Worked example: one accident, two deductibles
Hypothetical. On a rainy evening you swerve to avoid a deer, strike it, then continue off the road into a fence. The repair invoice reads: bumper and grille damage from the animal strike, $2,800; body panel and fence impact damage, $4,200. Your policy carries a $500 comprehensive deductible and a $1,000 collision deductible.
Because comprehensive and collision are separate coverages, insurers typically handle this as two claims (or two parts of one claim), each with its own deductible. The animal strike piece settles under comprehensive, less the $500 comprehensive deductible. The fence impact settles under collision, less the $1,000 collision deductible. You pay both deductibles, not one. Dollar figures are illustrative, not carrier-specific.
What changes the answer
- State and carrier. ISO PP 00 01 is the industry base form, but carriers can and do file company-specific endorsements and state-specific amendments. In some states, full-glass or zero-deductible glass is a filed option that modifies the comprehensive deductible for windshield claims only.6
- Policy form. Non-ISO policies (some direct writers use proprietary forms) can define collision and comprehensive differently. The ISO classifications on this page are the industry baseline; your declarations page and policy forms are the controlling text for your claim.
- Financing or leasing. Lenders and lessors typically require both collision and comprehensive for the life of the loan or lease. If you own the vehicle outright, either coverage can be dropped, with trade-offs covered in our when to drop collision and comprehensive guide.
- Full coverage. "Full coverage" is a market term, not a policy term; it almost always means liability plus both collision and comprehensive. See our full coverage guide for what it actually includes.
Exceptions and edge cases
- Hit-and-run and uninsured driver damage. Some states let uninsured motorist property damage (UMPD) pay for damage to your car caused by an uninsured at-fault driver, instead of collision. Where UMPD is not available, your own collision coverage responds. The result for you is similar; the deductible can differ.
- Riot and civil commotion. ISO PP 00 01 Part D lists "riot or civil commotion" among Other than Collision perils, meaning damage from a riot settles under comprehensive, not collision.1
- Rodent damage. Chewed wiring and nesting damage are usually treated as comprehensive losses by carriers because they derive from the presence of an animal, but some policies exclude gradual damage. Confirm with your carrier before assuming either way.
- Objects falling off the vehicle in front of you. If cargo falls off a truck ahead of you and strikes your car, that is typically treated as a falling object (comprehensive) rather than a collision, but carriers differ. The adjuster's classification drives which deductible applies.
- Mechanical breakdown riding alongside an accident. If a crash exposes a pre-existing mechanical problem, the crash damage settles under collision; the pre-existing mechanical problem is not a covered loss.5
