Car Rental: Should You Buy Their Insurance?
Renting a car often includes that familiar pitch from the counter agent: “Would you like to purchase our insurance coverage?” Many travelers feel pressured or uncertain, even if they planned to decline.
Understanding your options ahead of time can help you decide confidently.
Check Your Existing Coverage First
Most people don’t realize their personal auto insurance may already cover rental cars. In many cases, your policy extends the same collision, comprehensive, and liability protection to a rental vehicle as it does to your own car—subject to your policy’s terms, limits, and exclusions. If your personal policy lacks comprehensive and collision coverage, however, you could face significant out-of-pocket costs if the rental car is damaged or stolen. Before your trip, contact your insurance agent or review your policy to confirm exactly what is (and isn’t) covered when driving a rental.
Credit Card Coverage as a Backup
Another potential layer of protection comes from your credit card. Many premium cards (especially Visa, Mastercard, or American Express rewards cards) offer secondary rental car collision damage coverage. This typically kicks in after your personal auto insurance pays, covering damage to the rental vehicle itself.
Important limitations usually apply:
- It often excludes liability (damage to other vehicles or injury to others)
- Theft of personal belongings
- Certain vehicle types (e.g., luxury, exotic, or large trucks)
- Coverage may vary by card level (Platinum or higher often provides better terms than basic cards)
Call your card issuer or check their benefits guide before you travel to verify coverage details and any requirements (like paying for the entire rental with that card).
What the Rental Company’s “Insurance” Really Is
The coverage offered at the counter is typically called a Loss Damage Waiver (LDW) or Collision Damage Waiver (CDW). Importantly, it is not true insurance—it’s a contractual waiver that relieves you of responsibility for damage or theft of the rental car (often with a deductible). Rental companies may also upsell supplemental liability insurance to increase coverage beyond the state-minimum limits they carry. If your personal auto policy already has higher liability limits, this extra coverage may be redundant and expensive.
When It Might Be Worth Buying
LDW is often most valuable if:
- You carry only liability insurance on your personal vehicle (no collision/comprehensive).
- You want protection against loss-of-use charges (fees for the days the car is out of service during repairs) and diminished value/depreciation fees (common when rental companies later sell fleet vehicles).
These “consequential” charges are generally not covered by personal auto policies or most credit card benefits, potentially adding hundreds or thousands to your bill after an accident.
Making an Informed Choice
Before reaching the counter:
- Confirm your personal auto policy coverage.
- Check your credit card benefits.
- Ask the rental agent about their deductible, liability limits, and any loss-of-use or depreciation fees.
Weigh these against your current protection and your comfort with risk. There’s no universal right or wrong answer—only what makes sense for your situation.
