Accident in a rental car

The four possible sources

• Your own auto policy, which often extends to rentals in the US
• A credit card benefit, if you paid with that card and declined the counter product
• The rental company's own damage waiver and liability products
• Your travel or homeowners policy, in limited circumstances

The charge nobody expects

Rental companies commonly charge for loss of use — the revenue lost while the vehicle is off the road being repaired — and sometimes administrative fees and diminished value.

Not every policy or card benefit covers those. It's a frequent source of an unexpected bill after everything else has been settled, and it's worth asking about specifically.

Credit card coverage is usually secondary

Most card benefits are secondary, meaning they pay after your own auto insurance. A smaller number are primary and pay first, avoiding a claim on your own policy.

The distinction matters. Check which yours is before relying on it, and note that benefits usually require you to decline the counter waiver and pay with that card.

If you don't own a car

Without a personal auto policy there's nothing to extend to the rental. In that situation the rental company's products or a non-owner policy are the realistic routes.

This is the case where declining everything at the counter is genuinely risky rather than merely expensive.
