Must read: What’s primary and secondary insurance?
Your car rental contract might mention primary insurance and secondary insurance. The primary is the first place you’ll go when making a claim, and the secondary will cover anything extra on top of your primary.
Most credit cards offer secondary coverage, so you’d make a claim through your own personal policy or the rental insurance policy before accessing your credit card benefits. If your credit card offers primary insurance, that’s probably your best bet to avoid making a claim through your car insurance and potentially raising your rates.
