Collision insurance, as you can probably guess, covers damage to your car when it hits (or gets hit by) another vehicle or object. But because collisions aren’t the only way your car can get banged up, comprehensive insurance covers damage from events other than collisions: floods, fire, theft, and so on. Collision and comprehensive coverage make more sense for newer vehicles, and are generally required if you’re still making payments on your car. They’re less necessary — and may actually be a waste of money — on older cars.
