What You Need to Know About Insurance for a Loaner Vehicle

Your loaner car is usually covered by the rental company's insurance, but you may need to add your own coverage

When you pick up a loaner vehicle — whether from a dealership, repair shop, or rental company — insurance is already in place. The rental company carries a primary liability policy that covers damage you cause to other people or their property. However, that policy typically does not cover damage to the loaner car itself, theft, or medical bills from an accident. Whether you need additional coverage depends on what your own auto insurance covers and what the rental company offers.

Most people fall into one of three situations: your personal auto insurance extends to rental cars, the rental company offers damage coverage you can buy, or you use a credit card that covers rental damage. Understanding which applies to you before you drive off the lot saves you from paying out of pocket for damage you thought was covered.

Key Takeaways

• The rental company's liability insurance covers injuries and damage you cause to others, but not damage to the loaner car itself.
• Your personal auto insurance may already cover rental vehicles if you carry collision and comprehensive coverage, so check your policy before buying extra coverage.
• Rental companies offer damage waivers (called Loss Damage Waiver or Collision Damage Waiver) that you can purchase to cover the loaner vehicle, typically costing $15 to $30 per day.
• Some credit cards automatically cover rental car damage if you charge the rental to that card, but the coverage has limits and exclusions you should verify in advance.
• Declining all coverage and then causing damage means you pay the full repair bill yourself, which can exceed $5,000 for major damage.

What the rental company's insurance actually covers

The rental company carries liability insurance that pays for injuries to other people and damage to their vehicles or property if you cause an accident. This is required by law in every state. However, this policy does not pay for damage to the loaner car, theft, vandalism, or your own medical bills.

If you hit another car and injure the driver, the rental company's liability insurance covers their medical bills and vehicle repair. If you hit a parked car and leave the scene, the rental company's insurance still covers the other car's damage — but you may face legal consequences for leaving the scene. The rental company will then bill you for the cost of their insurance claim.

Liability coverage is mandatory and you cannot opt out. The question is whether you also need coverage for the loaner vehicle itself.

How your personal auto insurance may already cover a loaner

If you carry collision and comprehensive coverage on your own car, that coverage typically extends to rental vehicles. Collision covers damage from accidents; comprehensive covers theft, weather, vandalism, and other non-accident damage. You pay your own deductible (usually $500 to $1,000) just as you would for your own car.

Call your insurance company before you rent or pick up a loaner and ask: "Does my collision and comprehensive coverage apply to rental vehicles?" Some policies exclude rentals, and some limit coverage to cars rented for personal use (not business). Get the answer in writing or note the date and time you called and the agent's name.

If your coverage does apply, you do not need to buy the rental company's damage waiver. If you do not carry collision and comprehensive, or if your policy excludes rentals, you will need to buy coverage from the rental company or rely on a credit card.

Damage waivers offered by rental companies

Rental companies and dealerships offer a Loss Damage Waiver (LDW) or Collision Damage Waiver (CDW) — the names vary but the function is the same. You pay a daily fee (typically $15 to $30, sometimes more) and the company waives its right to charge you for damage to the loaner vehicle. This covers dents, scratches, broken windows, theft, and vandalism.

The waiver usually has exclusions: damage from off-road driving, racing, towing, or driving under the influence is not covered. Damage from normal wear and tear (worn tires, small chips in the windshield) is also typically excluded. Read the waiver document before you sign it to know what is and is not covered.

If you decline the waiver and cause damage, you pay the full repair cost. A major accident can cost $5,000 to $15,000. A minor dent might cost $500 to $1,500. The rental company will charge your credit card or send you an invoice.

Credit card coverage for rental vehicles

Some credit cards offer rental car damage coverage if you charge the rental to that card. Premium cards (American Express Platinum, Chase Sapphire Reserve, Capital One Venture X) often include this benefit. Some mid-tier cards also offer it. Basic cards rarely do.

Log into your credit card account or call the number on the back of the card and ask: "Does this card cover rental car damage?" Ask specifically whether it covers collision damage, theft, and vandalism. Ask whether there are limits on the daily rental cost or total claim amount. Ask whether the coverage applies to luxury vehicles or only standard cars.

Credit card coverage typically has a high deductible ($500 to $2,500) and may not cover certain types of damage (off-road use, racing, towing). It also usually requires you to decline the rental company's damage waiver in order for the card's coverage to apply. If you buy the waiver anyway, the credit card coverage becomes secondary and may not pay anything.

Deciding whether to buy coverage at the rental counter

Before you arrive to pick up the loaner, know the answer to these three questions: Does your personal auto insurance cover rentals? Does your credit card cover rental damage? If neither applies, you need the rental company's damage waiver.

If your personal insurance covers rentals, decline the rental company's waiver. You are already protected and paying twice is wasteful. If your credit card covers rentals and you want to use that coverage, decline the waiver and charge the rental to that card. If neither your insurance nor your credit card covers rentals, buy the damage waiver from the rental company.

The rental company will ask you to decide at the counter, often when you are tired or in a hurry. Having the answer ready means you will not be upsold coverage you do not need or left unprotected because you declined coverage you should have bought.

What happens if you cause damage and have no coverage

If you damage the loaner car and have not bought a damage waiver, your personal insurance does not cover rentals, and your credit card does not cover rentals, you pay the full repair bill. The rental company will document the damage with photos, get a repair estimate, and charge your credit card or send you an invoice.

You can dispute the charge with your credit card company if you believe the damage estimate is inflated, but the rental company has the right to charge for repairs. If the damage is severe enough that the car is a total loss, you may owe the full value of the vehicle minus salvage value — potentially $20,000 or more for a newer car.

Some rental agreements include a damage waiver in the base price, so check your contract. If you rented through your insurance company's repair network (after an accident), the insurer may have already paid for coverage. If you rented through a dealership while your car is being repaired, ask the dealership whether damage coverage is included.

Frequently Asked Questions

Do I need insurance if I'm only borrowing a loaner for one day?

One day or one week, the risk is the same: you could cause damage that costs thousands. If your personal insurance or credit card covers rentals, you are protected. If neither does, the daily cost of a damage waiver ($15 to $30) is worth the protection against a major bill.

What if the rental company says my insurance doesn't cover their loaner?

Call your insurance company directly and ask them, not the rental company. Rental companies have a financial incentive to tell you your coverage does not apply so you buy their waiver. Your insurance company has no such incentive. Get the answer in writing or document the call with the agent's name and time.

Can I buy damage coverage after I pick up the loaner?

Most rental companies and dealerships require you to decide at the counter before you drive off the lot. Once you have signed the contract and left, you typically cannot add coverage. Decide before you arrive.

Does the damage waiver cover accidents I cause while driving?

Yes. The damage waiver covers collision damage from accidents you cause. It does not cover damage from driving under the influence, racing, off-road use, or towing. It also does not cover your own medical bills — that is what your personal health insurance or the rental company's liability coverage is for.

What if someone else damages the loaner while I'm not driving?

If another car hits the loaner in a parking lot, the other driver's insurance should pay for repairs. If the other driver is uninsured or unidentified, your damage waiver covers it. If you have your own collision coverage that applies to rentals, that covers it too. Without either, you pay the repair bill.
