Locate Your Policy Documents
Start by gathering your current auto insurance declarations page, policy booklet, or online account summary. Look for a section titled "Rental Car Coverage," "Loss‑Damage Waiver," or "Extended Coverage." If the wording mentions coverage for "rented vehicles" or "temporary use vehicles," you likely have some protection.

Read the Coverage Details
Identify the type of coverage listed: liability, collision, comprehensive, or a combination. Liability typically follows the state minimum for any vehicle you drive, while collision and comprehensive may be limited to the same deductible as your own car. Note any exclusions, such as luxury cars, certain rental companies, or rentals longer than a specified number of days.
Check Your Policy Limits
Compare the liability limits in your policy to the minimum required by the state where you'll rent the car. If your limits are lower, the rental agency may require you to purchase additional coverage. For collision and comprehensive, confirm whether the maximum payout equals the rental's actual cash value or a set dollar amount.
Contact Your Insurer Directly
Call the customer service number on your insurance card and ask, "Does my policy cover rental cars, and under what conditions?" Request a written confirmation via email or portal message. Ask about any required endorsements or optional add‑ons you might need for full protection.
Review the Rental Agreement
The rental contract will list "Collision Damage Waiver (CDW)" or "Loss Damage Waiver (LDW)." If your insurer confirms coverage, you can decline these optional waivers, but keep the confirmation handy in case of a claim.
Compare Costs and Gaps
If your policy provides limited coverage, weigh the cost of the rental company's CDW against the risk of paying out‑of‑pocket for damage. Some credit cards also offer secondary rental car insurance, which can fill gaps.
