Collision vs. Comprehensive

These are the two coverages that repair your car, and they split the world between them. The line is cleaner than the names suggest.

Collision: you hit something, or something hit you

Another car. A pole. A curb. A wall. A rollover. If the damage came from impact while driving, that's collision — and it applies whether or not the crash was your fault, though if another driver is at fault their liability coverage may be the first place the claim goes.

Comprehensive: nearly everything else

Theft. Fire. Vandalism. Break-in glass damage. Hail and storm damage. Flood. A tree limb. And, in most policies, hitting an animal — which surprises people, because it feels like a collision but is generally handled as comprehensive.

Each has its own deductible

They're usually set separately, and they don't have to match. A common pattern is a higher collision deductible with a lower comprehensive one, on the reasoning that glass and theft claims tend to arrive without warning.

When you're required to carry them

If your car is financed or leased, your lender almost certainly requires both — that's a loan condition, not state law. California requires liability, not physical damage coverage on your own vehicle.

When to consider dropping them

On an older car with modest value, at some point the annual cost of these coverages plus the deductible approaches what the car would pay out. There's no universal threshold — it's a judgment about the car's value, your deductible, and whether you could replace it out of pocket. Worth pricing both ways rather than deciding by feel.

Choosing two deductibles instead of one

Because these are separate coverages they carry separate deductibles, and no rule says the two must match. Comprehensive losses tend to arrive without warning and often without anyone at fault — a stone off a truck, a break-in, a storm — which is why some people set that deductible lower and accept a higher one on collision. It is a cash-flow decision rather than a right answer. Price two or three combinations and pick the one you could actually pay on the day it happens.
