What Is a Rental Car Damage Waiver, Really?

A damage waiver isn't technically insurance — it's the rental company agreeing not to hold you financially responsible for certain types of vehicle damage, in exchange for a daily fee. It typically excludes certain things like tire damage, undercarriage damage, or damage from driving on unauthorized roads, so it's worth reading exactly what's excluded.

Comparing the waiver's cost against your existing coverage from a credit card or personal policy helps you decide whether it's worth adding for your specific trip.
