Why Rental Insurance Matters
Renting a car abroad means navigating unfamiliar insurance options. Declining coverage can leave you personally liable for thousands of dollars. Over-insuring wastes money. This guide helps you find the right balance.
Types of Rental Car Insurance
CDW / LDW — Collision Damage Waiver / Loss Damage Waiver
- What it covers: Damage to or theft of the rental vehicle
- What it doesn’t: Your injuries, other people’s injuries, other people’s property
- Typical cost: $15–30/day
- Key detail: CDW often has an excess (deductible) of $500–$3,000. You’re responsible for damage up to that amount.
SLI — Supplemental Liability Insurance
- What it covers: Damage you cause to other vehicles, property, or people
- Why you need it: Basic liability included in many rentals covers only the legal minimum — often far too low
- Typical cost: $10–15/day
PAI — Personal Accident Insurance
- What it covers: Medical expenses for you and your passengers
- Do you need it? Usually no, if your travel insurance or health insurance covers you abroad
Super CDW / Excess Reduction
- What it does: Reduces or eliminates the CDW deductible
- Worth it? Often yes, especially in countries with expensive repairs (Japan, Australia, Nordic countries)
Do You Already Have Coverage?
Before buying anything at the rental counter, check these:
- Your credit card — Many premium cards (Chase Sapphire, Amex Platinum, etc.) include CDW as a free benefit. Read the terms carefully — some exclude specific countries, SUVs, or rentals over 30 days.
- Your travel insurance — Many policies cover rental vehicle damage. Check limits and deductibles.
- Your home auto insurance — Some policies extend coverage to rentals abroad. Call your insurer to confirm.
Country-Specific Notes

| Japan | Full coverage usually included | Japanese rental companies bundle comprehensive insurance |
| Australia | Third-party included | Reduce excess from ~AUD $3,000 to $0 for ~$25/day |
| USA | Varies by state | Some states require SLI; credit card CDW usually works |
| Thailand | Basic coverage included | Quality of coverage varies; consider additional insurance |
Tips to Save Money
- Book through aggregators (Rentalcars.com, Discover Cars) — they often include CDW
- Use credit card coverage and decline CDW at the counter
- Buy standalone excess insurance (iCarhireinsurance, Worldwideinsure) for ~$4–8/day instead of $15–30/day at the counter
- Photograph the car before and after — document every scratch to avoid false damage claims
- Read the fuel policy — “full-to-full” is always cheapest
What to Do If You Have an Accident
- Don’t move the car unless blocking dangerous traffic
- Call the police if required (mandatory in most European countries)
- Photograph everything — damage, scene, license plates, road conditions
- Get a police report number
- Call the rental company immediately
- Don’t admit fault or sign anything you don’t understand
