Rental car insurance is a set of optional products sold at the counter, a collision or loss damage waiver (CDW/LDW), supplemental liability, personal accident and personal effects cover, that you may already have through your own auto policy or credit card. Counter prices are commonly reported at about $10 to $30 a day for the waiver alone, a CDW is technically a contractual waiver, not insurance, and most credit card benefits are secondary unless the card says otherwise.
Key Takeaways
- A CDW or LDW covers damage to or theft of the rental car, but it does not cover injuries or damage to other people’s property
- Reported waiver prices include $10 to $20 a day (Utah Insurance Department) and $20 to $30 a day (a credit-card guide), and a supplemental liability add-on can add $7 to $20 a day
- Most credit card coverage is secondary, though some premium cards offer primary cover, and you generally must decline the waiver and pay with that card
- Your own personal auto policy often extends to rentals, but a claim goes through your deductible and may raise your premium
- Business rentals, exotic vehicles, cargo vans and some countries are commonly excluded from personal and card coverage
What Is Rental Car Insurance?
The Utah Insurance Department explains that rental companies offer several insurance options your existing coverage may already provide. A University of California auto rental guide lists the main products: the collision or loss damage waiver, supplemental liability insurance, personal accident insurance and personal effects coverage. A rental-industry blog notes that major brands describe the CDW as a waiver, not insurance, meaning the company agrees not to pursue you for damage or theft up to the stated terms.
What Does Each Counter Product Do?
| Product | What It Covers | Reported Cost |
|---|---|---|
| CDW / LDW | Damage to or theft of the rental car, parking and towing-related charges | $10 to $20 a day (Utah); $20 to $30 (credit-card guide) |
| Supplemental liability (SLI) | Injuries and property damage you cause to others, above existing cover | $7 to $14 a day (Utah); $15 to $20 (Afar) |
| Personal effects | Theft of items from the car | $2 to $5 a day (Utah) |
| Personal accident | Medical costs for you and passengers after an accident | About $5 a day in one UC example |
Jerry says there is no standard definition, but a CDW usually covers accident damage while an LDW does the same for theft or vandalism. CardRatings adds that a CDW covers only damage to the rental vehicle, not injuries or property damage beyond it.
Does Your Own Policy or Credit Card Already Cover You?
Afar explains that your own auto policy typically serves as primary coverage for a rental, with your credit card as secondary, and that credit cards generally provide only secondary cover, though some premium cards, such as the Chase Sapphire cards, include primary rental coverage. If you have no insured car and do not buy a waiver, a card’s secondary coverage effectively becomes primary because there is nothing for it to follow. Utah’s regulator says most card benefits are secondary to your personal policy or the rental company’s insurance, so the card pays only after other cover is used. Smarter Travel notes that claims under your own policy are subject to your deductible and a possible premium increase.
- Personal auto policy: may extend collision and liability to a rental, partially or fully, so review the policy before the counter
- Credit card: usually requires paying the full rental with the card and declining the waiver, as My Rate Compass notes
- Non-owner policy: Utah’s regulator suggests considering one if you do not own a car
How Much Can You Spend at the Counter?
Jerry reports short-term coverage from a rental agency can run $5 to $120 a day depending on add-ons. A credit-card guide estimates the rental company’s waiver can cost $20 to $30 a day, so $140 to $210 over a week. Allianz sells a stand-alone rental damage protector at $11 per calendar day, primary for covered collision, loss and damage up to $75,000, and Smarter Travel says Bonzah sells coverage around $20 a day. As an illustration only, a $15 a day waiver over a seven-day rental adds $105 to the bill.
What Is Usually Not Covered?
Jerry warns your own car insurance or card cover might not extend to commercial or business rental vehicles. A rental-industry guide advises checking card exclusions for vehicle classes such as exotic cars and cargo vans, and for country limits, and notes that a card may require you to decline the rental company’s waiver to activate. The CDW from the rental brand often waives items that personal policies or cards may exclude, while personal policies do not usually apply to business travel, per Utah’s guidance.
When Is Buying at the Counter Worth It?
Utah’s regulator says that if you lack personal auto insurance and your credit card offers no benefit, it may be wise to buy the liability coverage and collision damage waiver at the counter. Smarter Travel’s rule of thumb is that rental company waivers are the most convenient but the priciest option, so compare them with your own policy, a primary-coverage card or a third-party plan before you travel.
