Short answer
The cheapest advertised rate is rarely the cheapest total. Rental companies make money on insurance you do not need, fuel you do not use, and fees you did not read. The core decision is the excess: the amount you pay if the car is damaged. If you book with full CDW and zero excess included, or use a credit card that covers the excess (after confirming the card issuer’s written terms), you can decline the counter's upsell and save a lot.
Before you drive off, photograph every scratch and dent, check the fuel gauge, and read the terms on border crossings and additional drivers. The rental is only a good deal if you know what you are on the hook for.
Steps to a clean rental
Book through a comparison site to see the range, but read the rental company's own terms before paying. The comparison site is a broker; the contract is with the rental company.
Decide your insurance strategy before you arrive. Option A: book a rate that includes full CDW with zero excess. Option B: use a credit card that covers the excess – but only after you have checked the card issuer’s written terms and confirmed it applies to the rental location, vehicle class and booking method, then decline the counter's CDW. Option C: buy a separate excess insurance policy from a specialist provider, which is often cheaper than the counter's daily rate.
At the counter, decline the extras you do not need: CDW if you are already covered, personal accident insurance (often covered by your health or travel insurance), and pre‑paid fuel. Ask for the final price in writing, including taxes and any one‑way fee.
Inspect the car with the agent. Walk around, take photos and video of every panel, wheel, and the interior, and note existing damage on the rental agreement. Check the fuel level and the odometer. If the agent does not walk with you, take your own timestamped photos.
Before you drive, set up the phone for navigation, adjust mirrors and seat, and check the headlights and indicators. Know the local rules: which side of the road, speed limits, and whether you need a vignette or toll pass.
Return the car with the same fuel level as when you picked it up, unless you chose a full‑to‑full policy. Allow time for the return inspection, and take a photo of the fuel gauge and the odometer at drop‑off.

Exceptions and special cases
Some countries have different rules. In Japan, most rental companies require an International Driving Permit (IDP) for non‑Japanese licences and a credit card for the deposit; cash deposits are uncommon. In Iceland, the terrain and weather mean you should consider gravel protection and sand‑storm cover, which are often not included in the standard CDW.
In the United States, liability insurance is mandatory, and many travellers rely on their personal auto policy or a credit‑card supplement that meets local minimums. In Mexico, basic rental rates often include only the statutory minimum liability; you may need to purchase additional Mexican liability coverage separately.
Cross‑border rentals: many companies forbid taking the car into another country without written permission, and some countries (e.g., Italy, Spain) require a special permit for driving on certain roads or in low‑emission zones. Check the rental terms for the list of allowed countries.
Electric vehicles: charging costs and range are different; some companies charge a fee if you return the car with less than a certain charge level. Read the EV policy before booking.
Questions people ask
Renting a car abroad: what is the short answer?
Book with full CDW and zero excess, or use a credit card that covers the excess. Decline the counter's insurance if you are covered. Take photos before driving off, and return the car with the same fuel level.
Who does it apply to?
Anyone renting a car in a foreign country. The rules are similar everywhere, but age, border, and insurance rules vary by country and company.
How much does it cost and how long does it take?
A small car costs €30–80 per day, plus insurance, fuel, and fees. The counter process takes 30–45 minutes, and returning takes 10–15 minutes.
Is the rental company's CDW worth it?
Only if you do not have other coverage. The counter's CDW is usually the most expensive way to reduce the excess. A separate excess policy is often cheaper.
Does my credit card cover rental car insurance?
Many premium cards do, but only if you decline the rental company's CDW and use the card for the booking. Check your card's benefits guide for the exact terms and any exclusions.
What is the fuel policy I should choose?
Full-to-full is almost always the best deal. You pay for the fuel you use, and you avoid the pre-purchase markup.
Can I take the rental car across a border?
Often not without written permission. Some companies forbid it entirely, and others charge a fee. Check the rental terms for the list of allowed countries.
What happens if I damage the car?
You pay the excess, unless you have CDW or a separate excess policy. Take photos before and after to document the condition.
Do I need an International Driving Permit?
In many countries, yes, especially in Japan, and some European countries require it for non-EU licences. Check the local rules before you travel.
