FAQ
Do I need rental car insurance if I have full coverage?
If you have collision and comprehensive on your personal policy, those coverages typically transfer to rental cars. However, you may still want the rental company's CDW to avoid paying your deductible and potential loss-of-use fees. Credit cards with primary coverage can fill this gap.
Does my credit card cover rental car insurance?
Many credit cards offer secondary or primary rental car coverage. Secondary means it pays after your personal insurance. Primary means it pays first, keeping claims off your personal policy. Check your card's benefits guide for specific coverage details and exclusions.
What is loss of use and why should I care?
Loss of use is what the rental company charges for revenue lost while a damaged car is being repaired. This can be $50-100+ per day. Your personal insurance typically doesn't cover this. Some credit cards and rental company CDW do cover it.
Does rental car insurance cover me in another country?
Your personal auto insurance generally does not cover international rentals. Some credit cards offer international coverage. Mexico specifically requires separate Mexican liability insurance. Always check coverage before renting abroad.
What happens if I damage a rental car without insurance?
You're personally responsible for all repair costs, loss of use, diminished value, and administrative fees. The rental company will charge your credit card and may pursue collections. Without coverage, these costs can easily reach thousands of dollars.
Conclusion
Rental car insurance isn't always necessary, but understanding your coverage gaps is essential. Review your personal policy and credit card benefits before you reach the rental counter.
