Yes, you legally must have to drive a rental car in almost every country. However, the key is securing the right coverage without overpaying. Rental companies often sell expensive policies with high deductibles, sometimes exceeding $2,500. Your existing personal auto insurance or premium card may provide adequate primary coverage, but you must verify the terms for international use and rental car classes.
The primary risk is not the lack of insurance but facing a hefty out-of-pocket expense due to a high excess (also called a deductible). Rental companies profit from selling products to reduce this excess to zero. Understanding your existing coverage is the most effective way to avoid unnecessary costs.

Actionable Verification Checklist:
| Coverage Source | Typical Protection | Key Considerations & Pitfalls |
|---|---|---|
| Rental Company CDW | Primary coverage for damage/theft to the rental car. | High excess (often $1,500-$2,500). Costly daily fee. Easy but expensive. |
| Personal Auto Policy | May extend liability & comprehensive/collision. | Rarely applies internationally. Limits may be inadequate. Claims affect domestic rates. |
| Premium Credit Card | Often primary CDW coverage. | Strict exclusions (countries, vehicle types, rental duration). Must decline rental company CDW. |
| Travel Insurance Add-on | Covers the rental company's excess (deductible). | Usually secondary coverage. Must have a primary policy (like credit card CDW) first. |
Ultimately, driving uninsured is illegal and risk-laden. The financially savvy approach is to use a credit card that provides primary CDW as your base coverage, confirm its validity for your destination, and consider a travel insurance policy to cover the excess or fill any gaps. Always carry documented proof of your coverage to the rental desk.

As someone who rents cars in Europe almost every year, here’s my routine. I never buy the rental company's full . It’s a wallet-drainer.
I use a credit card that I’ve confirmed offers primary rental coverage in the countries I’m visiting. Before every trip, I call the card issuer to double-check. I print out the benefits guide and bring it with me.
At the counter, I politely but firmly decline their CDW, showing my card and documentation. I do purchase the mandatory local third-party liability insurance, which is usually minimal. This method has saved me hundreds over the years. The peace of mind comes from doing the homework upfront, not from buying the most expensive option.

Think of it as a three-layer verification process before you ever reach the rental counter. Missing a step can leave you exposed or wasting money.
Layer 1: Investigate Your Personal Resources. Scrutinize your auto policy's fine print for "territory" clauses. Most stop at the U.S. and Canada. Then, call your credit card company. Ask: "Does my card provide primary rental car collision coverage in [exact country]? Are there any excluded vehicle categories (like stations wagons or SUVs)? What is the maximum rental period covered?" Get a confirmation number or email.
Layer 2: Identify and Bridge Gaps. If your card covers damage to the rental car but the excess is $2,000, bridge that gap. A standalone travel insurance policy with rental car excess coverage often costs less than the rental company's excess reduction product for a two-week trip.
Layer 3: Prepare for the Counter. Have your driver’s license, passport, credit card, and printed proof of coverage ready. The agent will try to sell their insurance. A simple "No, thank you, I have my own coverage" suffices. They may require you to sign a waiver acknowledging you declined their CDW. This is standard.

Let’s cut through the confusion. You need —that’s the law. The real question is, where should you buy it? The rental counter is the most expensive place.
Your own tools are cheaper. A good travel credit card is your best friend here. But you can’t just assume it works. You have to check. I’ve heard stories of people thinking they’re covered, only to find out their card doesn’t cover rentals in Italy, for example.
The big scare tactic is the excess. They’ll show you a figure like €2,000 and ask, “Can you afford this if something happens?” That’s what makes people panic-buy. Instead, remain calm. If your credit card is your primary coverage, that excess is what the card would pay. Some travel insurance policies will reimburse you for that exact excess charge, for a much lower total price.

Here is a step-by-step guide to securing proper coverage without overspending.
Step 1: Establish Your Primary Damage Coverage. This covers the rental car itself. Your goal is to find a primary coverage source so you can confidently decline the rental company’s CDW. The most reliable method is using a premium card that explicitly includes this benefit. Confirm the details in writing. If you lack such a card, your only prudent option may be to purchase the rental company’s CDW, but you can then proceed to Step 2 to reduce its cost.
Step 2: Address the Excess (Deductible). Primary coverage still has an excess. Contact your existing travel insurance provider or compare policies on aggregator sites. Look for "rental car excess coverage" or "collision damage waiver supplement." For a single trip, this can cost significantly less than the rental company's daily excess reduction fee. It acts as a secondary policy, reimbursing you if you have to pay that excess.
Step 3: Ensure Adequate Third-Party Liability. This covers damage you cause to others. The rental includes the local legal minimum, but it may be low. Your personal auto policy might not extend overseas. To boost this, consider a third-party liability supplement from the rental company or ensure your standalone travel insurance includes elevated liability limits.
Step 4: Document and Present. Organize all documents: credit card benefits guide, travel insurance certificate, and your driver’s license (often an International Driving Permit is required alongside your native license). Present these at the counter. This preparation shows you are informed and prevents successful upselling.
