Costa Rica rental insurance, plain English
Why your $10/day quote becomes $60 at the counter — and how to avoid it.
1. The INS TPL is mandatory. By law.
Costa Rican law requires every rental car to carry a Third-Party Liability (TPL/SLI) insurance issued by INS, the state insurer. You cannot waive it. Your US auto policy doesn't replace it. Your Visa Signature, Amex Platinum, or Chase Sapphire don't replace it. It costs $14–$30 per day.
2. The $10/day quote almost never includes the TPL.
That's why the counter price explodes. Big chains (Hertz, Avis, Budget) also push their own CDW (collision damage waiver) on top — that one is optional, but they present it as mandatory.
3. CDW — when to decline.
If your credit card (Visa/MC Platinum, Amex, Chase Sapphire) covers rental car damage internationally, you can decline the operator's CDW. Call your bank before the trip and get written confirmation it covers Costa Rica — some cards explicitly exclude CR.
4. The hold can be brutal.
Big operators put a $1,500–$3,000 hold on your credit card. Independents are more reasonable ($500–$1,500). Make sure your credit limit can absorb it.
5. How to avoid the counter shock.
Book with an independent operator that quotes all-in (TPL included). Ask for a written breakdown before traveling. Bring a credit card with rental car coverage. The operators we list on Carros506 quote transparently.
