Do You Really Need the Extra Insurance When Renting a Car
If your own car insurance and credit card already cover a rental, you don't need the extra policy the counter is selling.
Your coverage follows you, it doesn't stay with your own car
Car insurance policies generally cover you as a driver, not just the specific vehicle listed on them. That means if your policy includes liability, collision, and comprehensive coverage, those protections typically extend to a rental car the same way they'd apply to your own. The rental counter doesn't know what your policy covers, so they offer their own coverage to everyone, whether you need it or not.
Credit cards often add another layer on top of that. Many cards include secondary rental coverage automatically when you use that card to pay for the rental, which kicks in to cover costs your own insurance doesn't, like your deductible. Some cards offer primary coverage instead, which pays out before your own insurance is touched at all. The type of coverage and what it includes varies by card issuer, so check your card's benefits guide or call the number on the back before you assume anything.
Where this gets more complicated is with things your regular policy and card might not cover. Loss of use, which is what the rental company charges you for the time the car sits in the shop, is sometimes excluded from both. Renting in another country can also change the picture completely, since many policies and card benefits only apply domestically.
The other case where the extra insurance makes sense is when you don't have your own auto policy at all, or when the coverage you have is minimal. If you're renting a car but don't own one, there's nothing at home to extend to the rental, so the counter's coverage might be the only protection you have.
What to check before you say no to the extra coverage
- Your policy's limits Confirm your auto policy includes collision and comprehensive, not just liability. If you only carry liability, a rental's damage wouldn't be covered by your policy at all.
- Your card's rental benefit Call your card issuer or read your benefits guide to see if coverage is primary or secondary. This changes whether your own insurance gets involved at all.
- Loss of use coverage Ask whether your policy or card covers the rental company's lost rental income while the car is repaired. This cost is often excluded and can surprise you later.
- Where you're driving Check if your coverage applies outside your home country. International rentals often fall outside both your policy and your card's protection.
- Your deductible amount Know what you'd pay out of pocket if the rental were damaged under your own policy. A low deductible makes skipping the extra coverage an easier call.
What happens if I decline and then damage the rental car?
Your own insurance process kicks in, the same way it would if you'd damaged your own car. You'd report the claim to your insurer, pay your deductible, and your insurer would pay the rest based on your policy's limits for collision or comprehensive coverage.
If your credit card offers secondary coverage, you can often use that to cover the deductible, which means the damage ends up costing you little or nothing beyond your time. If your card offers primary coverage instead, you may be able to skip your own insurer entirely and let the card company handle the claim directly with the rental company.
The one wrinkle is a possible claim on your driving record and a potential increase in your future premiums, since this would count as a claim on your policy just like any other accident. That's worth weighing against the cost of the counter's coverage, especially if you rent often.
Once you know what your policy and card cover, compare quotes to confirm that protection is as strong as you think.
A weekend rental and a parking lot scrape
Say you rent a car for a weekend trip and back into a pole in a parking lot, denting the bumper. You declined the counter's coverage because you checked ahead of time and knew your own auto policy includes collision coverage, and your credit card offers secondary protection on top of that.
You report the damage to the rental company, then file a claim with your own insurer, who sends you to pay your deductible first. You then submit that deductible charge to your credit card company along with the claim paperwork, and the card issuer reimburses you for that amount since it only kicks in after your own insurance pays its share. In the end, the dent costs you nothing but some paperwork and a slightly inconvenient afternoon, and the only lasting effect is a claim on record with your insurer, which is worth watching if you're due for a renewal soon.
The extra insurance doesn't protect you, it just covers what you never checked.
