Should you purchase rental car insurance?

Question

StPhoebe · Accepted Answer

Purchasing rental car insurance is unnecessary if your personal auto policy or premium credit card already provides adequate coverage. However, it becomes a critical purchase if you lack personal coverage, want to avoid high deductibles, are traveling internationally, or wish to prevent potential premium increases on your primary insurance.

The decision hinges on a clear understanding of your existing protections. Industry analysis consistently shows that for domestic renters with full-coverage personal auto insurance, duplicate rental coverage is often an unnecessary expense. Your personal policy typically extends liability, collision, and comprehensive coverage to rental cars, though policy terms vary. Similarly, many premium credit cards (e.g., Chase Sapphire Reserve, American Express Platinum) offer primary rental car insurance, waiving the need to involve your personal insurer for damage claims, provided you decline the rental company's collision damage waiver and charge the entire rental to that card.

Key scenarios where purchasing the rental company's insurance is financially prudent:

No Personal Auto Insurance: If you don't own a car or carry only state-minimum liability insurance, buying the rental company's Collision Damage Waiver (CDW/LDW) and liability coverage is essential.
High Personal Deductibles: If your personal policy has a deductible of $500 or $1,000, the rental company's waiver, which often has a $0 deductible, protects you from out-of-pocket costs for minor damage.
International Travel: U.S. auto insurance is frequently invalid outside the U.S. and Canada. Rental insurance at your destination is often the only compliant option.
Protecting Personal Insurance Premiums: Filing a claim through your insurer for a rental incident can lead to increased premiums at renewal. Using the rental company's coverage keeps the claim off your personal record.
Renting Specialty Vehicles: Standard credit card benefits may exclude coverage for trucks, vans, luxury vehicles, or certain SUV categories.

The table below summarizes common coverage sources and their typical scope:

Coverage Type	Typically Provided By	Key Consideration
Damage/Loss to Rental Car (CDW/LDW)	Personal Auto Policy (Comprehensive/Collision)	Subject to your policy deductible.
	Premium Credit Cards (Primary Coverage)	Must typically decline rental company's CDW.
	Rental Company (Purchased)	Usually offers $0 deductible.
Liability Insurance	Personal Auto Policy	Must meet or exceed rental state/country minimums.
	Rental Company (Supplementary Liability Insurance)	Crucial if personal limits are low or nonexistent.
Personal Accident Insurance	Personal Health Insurance / Travel Insurance	Often duplicates existing coverage.
Personal Effects Coverage	Homeowner's/Renter's Insurance	May cover items stolen from the rental car.

Before any trip, conduct a two-minute coverage check: call your auto insurer to confirm rental coverage specifics and exclusions, and review your credit card's guide to benefits for precise coverage limits and country restrictions. This proactive verification is the most reliable way to determine if you need to purchase additional coverage at the rental counter.

As someone who rents cars for work every month, my rule is simple. I never buy the insurance from the rental counter. My company's corporate American Express card provides primary coverage, and my own insurer confirmed my policy extends to rentals. Paying for the rental company's waiver would be throwing away $30 a day.

The only time I've ever considered it was on a vacation in Italy. My credit card coverage had fine print excluding that specific country. I bought the full package from the local rental agency for peace of mind. It's not about fear, it's about knowing the rules of the game before you play.

Let me tell you about my first and only time skipping the rental insurance. I was sure my dad's policy covered me. A shopping cart dinged the door in a lot. No big deal, I thought. The hassle that followed was enormous. My dad's deductible was $1,000, and the rental company charged over $500 for "loss of use" fees while the car was being repaired—a cost my personal policy didn't cover.

The rental company's own damage waiver would have covered all of it with zero out-of-pocket cost. Now, I always buy it if I'm using my personal insurance as the primary coverage. The potential savings aren't worth the financial risk and administrative nightmare of a claim, even for a minor scrape. For me, that fee is a direct purchase of convenience and a predictable cost.

Think of it as risk transfer, not just "insurance." You're shifting financial uncertainty from yourself to the rental company for a known daily fee.

Do you already pay for comprehensive auto insurance? Does your travel credit card offer primary rental coverage? If the answer to either is yes, you're likely already paying for rental protection. Buying more is often redundant.

The real value is in gaps: traveling abroad, high personal deductibles, or lacking your own policy. In those cases, the rental company's product isn't an upsell—it's your primary financial safeguard on the road.

I don't own a car, so I rely on rideshares and rentals. When I need a rental, purchasing the insurance is non-negotiable for me. I have no personal auto policy to fall back on, so the rental company's Collision Damage Waiver and Liability Insurance are my only protection.

I learned this the hard way after a minor fender-bender years ago. I was on the hook for the entire repair cost because I had opted out. Now, I factor the daily insurance cost into my rental budget from the start. It makes the total price clear and eliminates surprise expenses.

For fellow non-car-owners, my advice is to consider the rental insurance a mandatory part of the rental fee. The alternative—potentially facing thousands in repair bills or liability claims—is simply not a risk worth taking. It's the cost of accessing a car when you need one without the burden of year-round insurance payments.
