Car rental abroad: 12 traps that will cost you money at the counter (2026)

Car rental abroad — why the price comparison is almost never the final price

A rental car for €9 a day sounds great. But at the counter, you're suddenly faced with a €340 deposit on your credit card, insurance for €22 per day, and the question of whether you'll return the car "full or empty." It's precisely between these two moments—booking and pick-up—that the money you saved by comparing prices vanishes.

I've been renting cars abroad for over ten years, in more than 80 countries and on over 40 road trips. The costly mistakes are repeated all over the world—and almost all of them can be avoided before departure. Here are the twelve most common ones.

Trap 1: The deposit — and why a debit card can leave you stranded

The security deposit is the most common reason why travelers arrive at the rental counter without a car. Rental companies block an amount on a deposit. credit card, The card is in the name of the main driver. "Blocked" means the amount won't be debited, but it won't be available to you until the card is returned. With a card limit of €1,000 and a €900 deposit, there's not much left for your holiday.

Three rules that apply everywhere:

• Credit card, not debit card. Many landlords don't accept debit or prepaid cards at all because no amount can be blocked on them. Some only accept them if you also buy the full insurance package — which negates the comparative price.
• The name on the card must be the name of the main driver. Your partner's card won't help, even if you're traveling together.
• Plan for sufficient budget. The deposit amount is stated in the rental terms and conditions of the respective offer. It depends on the vehicle class and country, not the rental price — a cheap compact car in Iceland may have a higher deposit than a mid-range car in Portugal.

Those who don't have a credit card should specifically filter for offers marked "Debit card accepted" — they exist, they are just less common and usually a bit more expensive.

Trap 2: „Comprehensive insurance“ is not „without excess“

This is the most expensive mistake on the entire list. Almost every rental car comes with a liability waiver, often called CDW or comprehensive insurance in the offers. It limits your liability—it doesn't eliminate it. What remains is the Deductible: the amount you will have to pay yourself in the event of damage.

A scratch on the door, for which the garage charges €400, is entirely your responsibility if you have a deductible of €1,200. The insurance only covers damages exceeding this amount. Therefore, the only figure that truly matters in the quote is not the daily rate, but the amount of the deductible.

You have three ways to get rid of them:

1. Buy it at the landlord's counter. The most convenient and by far the most expensive way — this is where sales are made under time pressure, while there is a queue behind you.
2. Book via the comparison portal. In case of damage, you initially pay yourself and then get reimbursed. Significantly cheaper, but requires you to collect receipts.
3. A separate annual excess insurance policy. It becomes worthwhile from about the third rental per year — the cheapest way for frequent travelers.

Important for options 2 and 3: You will always need the landlord's invoice for the damage. Without this invoice, no one will reimburse you.

Trap 3: The sales conversation at the counter

The counter isn't a service point, but a sales area. After the third rental, you know the standard phrases by heart: that your existing insurance "doesn't apply here," that the roads are "difficult," that an upgrade "only costs €8 more.".

Two sentences are enough as an answer: "I have my own insurance and will pay the deductible myself." And: "Please note in the record that I declined the additional package." After that, the conversation is usually over. Legally, you don't have to buy anything extra—the contract stands.

Trap 4: Tires, glass, underbody, roof

These four components are excluded from many standard liability limitations. This is no coincidence: they are precisely the types of damage that occur most frequently and can easily be attributed to the driver. A stone chip in the windshield on a gravel road, a punctured tire on a curb, a scratch on the underbody in an unpaved parking lot.

If you're driving on gravel roads, coastal tracks, or in mountainous regions—precisely the kind of routes you'd rent a car for—check before booking whether these four points are included. Packages that cover them are called "Full Coverage" or "Super Cover," depending on the provider. The extra cost is almost always well worth it on such routes.

Trap 5: The fuel policy

There is only one good one: Full throttle, full throttle back. You receive the car with a full tank and return it with a full tank. Anything else will cost you money.

Practical tip: The last gas station before the airport is usually the most expensive in the area. Filling up ten minutes earlier will save you a noticeable amount of money if you have a large tank. Keep your gas receipt until you receive the final bill—it's your proof that you returned the car full.

Case 6: Young driver and senior driver surcharge

If you're under 25, most rental companies charge a daily surcharge; in some countries, drivers under 21 aren't even eligible to rent a car. Drivers over 70 may also face restrictions, depending on the country and rental company. These restrictions are often not included in the initial price comparison but are only found in the rental terms and conditions—and are payable at the counter.

If you fall into these age groups, filter your search accordingly and calculate the surcharge over the entire rental period before comparing offers. For a two-week rental, a daily surcharge can quickly turn the seemingly cheapest provider into the most expensive.

Trap 7: The additional driver

Anyone not named in the contract is not allowed to drive. Period. If something happens while an unlisted person is behind the wheel, the insurance coverage is void—completely void, not just the deductible.

The additional driver costs a daily rate depending on the provider and country; sometimes it's free. On long journeys—Australia, New Zealand, Chile, the vast Scandinavian countries—it's not a luxury, but a safety feature. Eight hours alone behind the wheel is not a good idea, and the risk is disproportionate to the cost.

Trap 8: Border crossings and ferries

Many rental agreements only allow leaving the country with prior authorization, and some prohibit it entirely. This is particularly relevant in the Balkans (Croatia to Montenegro, Bosnia, or Albania), the Baltic states, and South Africa. Ferry crossings are also frequently excluded—a real issue for island hopping in Greece or Croatia.

Indicate your border crossing when booking. There's usually a fee and a green insurance card is required. Without registration, you could be driving without insurance coverage—and a breakdown or accident in the neighboring country could be very unpleasant.

Trap 9: The one-way rental

Pick-up in Lisbon, drop-off in Porto: convenient, but rarely free. The one-way fee covers the return of the vehicle and can reach three figures for long distances—and considerably more in countries like Australia or New Zealand, where there are thousands of kilometers between the pick-up and drop-off points.

Check both options: Sometimes the round trip with return to the starting point is cheaper than the route plus fee, even if you factor in a domestic flight or an extra night.

Trap 10: Tolls, vignettes and environmental zones

Toll systems vary completely from country to country, and rental cars do not automatically include them:

• Vignette countries Like Switzerland, Austria, Slovenia, or the Czech Republic: Rental cars from the respective country usually come with a vignette – vehicles from neighboring countries do not. Check before crossing the border.
• Electronic toll As in Portugal or on many routes in Italy and France: ask for the transponder. Without it, you'll receive a bill later including a processing fee from the rental company.
• Environmental zones and city center closures, for example in Italian old towns: The cameras catch everyone, the fine arrives months later via the landlord — plus his processing fee.

Trap 11: The handover check that almost nobody does

This is where you'll save the most money — and it only takes five minutes. Before you leave:

1. Walk around the car and film it continuously, including the roof and the areas under the bumpers.
2. Photograph each scratch individually from two angles, with a recognizable surrounding area, so that the vehicle can be identified.
3. Take a picture of the fuel gauge and mileage.
4. Check the tire tread and windshield for any stone chips.
5. Have any damage found noted in the handover protocol and give yourself a copy. No entry, no signature.

The same applies to returns – especially if you leave the car outside of opening hours and no one is there with you to inspect it. In that case, a timestamped video is your only proof.

Case 12: Driving licence and international driving licence

Within the EU, a German driving license is sufficient. Outside the EU, many countries also require a German driving licence. International Driving Permit — It is not a separate document, but only a translation, and is valid only together with the original. It is issued by the driver's license authority, usually within a few days.

It's cheap and quick to get — and without it, you can be refused collection at the counter, even if the booking has already been paid for. For long-distance travel, it belongs in the same folder as your passport. Which countries require it is stated in the rental terms and conditions of the specific offer and on the website of the Federal Foreign Office.

My booking order

This is how I proceed every time now — the order is more important than the individual step:

1. Book early, free cancellation. Rental car prices almost always rise as the travel season approaches. A refundable offer is a price cap that costs nothing.
2. Filter by excess amount, not by daily price. Only when the deductible has been clarified can two offers be compared at all.
3. Read the rental terms and conditions of the specific provider. — Deposit, fuel policy, mileage limit, border crossing. That's four numbers, not twenty pages.
4. Add additional drivers at the same time, if there are two of you.
5. Compare again two weeks before departure. If the price has dropped, I'll cancel and rebook. That's exactly what free cancellation was for.

Before every trip, I compare prices on a portal instead of directly with the rental company—not out of convenience, but because the price differences for the exact same vehicle at the same airport are regularly in the hundreds.

Where a rental car is really worthwhile

You don't need a car everywhere—in cities, it's usually an expensive parking problem. But there are regions where, without your own vehicle, half the journey is simply impossible. I've traveled through these regions myself and described them in detail:

• Albania — hardly any public transport between the coastal towns, but low rents and empty streets.
• Great Ocean Road, Australia — The viewpoints are located between the towns, not within them. You can't see them without a car.
• New Zealand — the country is geared towards self-drivers; public connections between the national parks are sparse.
• Portugal — the most beautiful beaches in the Algarve are located at the end of dead-end roads without a bus stop.
• Andalusia — realistically, you can only reach the white villages in the hinterland by car.
• Chile — Distances like in hardly any other country; here, the additional driver also counts.

Frequently Asked Questions

Do I absolutely need a credit card to rent a car?

In most cases, yes, because the deposit is blocked on it. Some providers accept debit cards, but often only in conjunction with the full insurance package. In that case, filter specifically for that option instead of hoping for it at the counter.

Is insurance without a deductible worthwhile?

With a deductible in the four-figure range, it's almost always possible—especially on gravel and mountain roads. It's almost always cheaper than at the counter if you book it online in advance or have an annual policy.

What is the best fuel policy?

Full speed ahead, full speed ahead. Anything else means you're paying for fuel you're not using, or service fees that no one itemizes.

Is my partner allowed to ride along and drive?

Passengers are always welcome, but drivers are only permitted as registered additional drivers. Without registration, insurance coverage is completely void in the event of an accident.

Am I allowed to take the rental car to the neighboring country?

Only if the rental agreement allows it and you have registered it. In the Balkans and the Baltic states, this is regularly restricted; ferry crossings are often completely prohibited.

When is the cheapest time to book?

Book early and free of charge, then compare prices again shortly before your trip. Prices rise during peak season because the fleet is limited at your destination — unlike flights, there are hardly any last-minute discounts.

Do I need an international driving permit?

Within the EU, no. Outside the EU, many countries require it in addition to the national driving licence. It can be obtained quickly and cheaply from the driving licence authority — if in doubt, take it with you.

What do I do if damage is claimed upon return?

Don't sign anything you haven't checked, and show your own photos of the handover. Demand a written list of the damages with a cost estimate—you'll need this anyway if you're going to claim from an external insurance company.
