Whether you should buy the rental company’s insurance depends on what coverage you already have and your personal risk tolerance. Here’s a practical decision framework most people use:
Skip the rental company insurance if ANY of these apply:
- Check if your personal auto policy include coverage for rental cars.
- Most major credit cards (Visa, Mastercard, AmEx, Chase Sapphire, etc.) offer primary or secondary collision damage waiver offer rental car insurance coverage. Note: Almost always this coverage excludes liability, theft of personal items, and exotic/luxury vans/trucks. You must decline rental company CDW and charge the entire rental to that card.
- Check if your travel insurance (e.g., Allianz, World Nomads, credit-card trip insurance) includes rental collision.
Buy (or seriously consider) rental company insurance if:
- You have no personal auto insurance (e.g., you don’t own a car).
- You’re driving in a country where your U.S./home policy explicitly excludes coverage (fairly rare, but happens in Ireland, Jamaica, Israel, etc.).
- Your credit card coverage is secondary and you don’t want to deal with filing through your personal policy first (deductible + possible rate hike).
- You want zero-deductible peace of mind and don’t mind paying $30–$60/day extra.
