Renting a Car Abroad: Requirements, Documents & What Desks Actually Check (2026)
Every year travellers get turned away at rental desks — or hit with charges they never expected — because they showed up with the wrong documents. The rules are not complicated, but they are strict, and the desk agent has zero flexibility: no matching credit card, no car. This guide covers exactly what Hertz, Avis, Sixt, Europcar and local agencies check at pickup, the age rules, the deposit holds, the insurance fine print, and the scams to watch for in 2026.
The four documents every rental desk asks for
Whatever country you land in, the counter checklist is nearly universal:
- Your original driving licence. The physical card, valid, not expired, held for at least one year (many companies require two). A photo of your licence on your phone is never accepted.
- An International Driving Permit (IDP), where applicable. If your licence is not in the local language or not in the Latin alphabet, most countries and rental contracts expect the permit alongside it. Some countries require it by law for foreign drivers — Thailand and Japan are strict examples; see our Thailand permit guide. US and Canadian licence holders renting in Spain or Italy are routinely asked for one too — details in our Spain guide. Note: EU/EEA licence holders do not need one anywhere inside the EU.
- A credit card in the main driver's name. This trips up more renters than anything else. The card must be a real credit card (debit cards are often refused or force you into expensive full-coverage packages), and the name on it must match the name on the booking and the licence. Your partner's card will not work unless they are registered as the main driver.
- Your passport. Used for identity verification, and in many countries the agency is legally required to record it.
Print your booking confirmation too. If the desk's system is down or the price mysteriously changes, the paper voucher is your evidence.
Age rules: under 25 and over 70
The minimum legal driving age and the minimum rental age are different things. In most of Europe you can hold a licence at 18, but rental companies set their own floors:
- 21 is the practical minimum with most major brands in Europe, and some categories (vans, premium, automatics) require 23–25.
- Young driver surcharge (roughly ages 21–24): expect around €15–40 per day on top of the rental. Sixt charges up to €38/day on selected car groups; in France fees of €30–40/day are common; in the UK some suppliers charge up to £40/day. It is capped per rental with some brands — always check.
- Senior drivers: most of Western Europe has no upper limit, but there are exceptions. In Ireland many suppliers will not rent to drivers over 75, and those who do may ask for a doctor's letter and a clean five-year driving record. Some Portuguese suppliers cap at 80. If you are 70+, confirm the supplier's policy in writing before you book, not at the desk.
Deposits and credit card holds
The desk does not just swipe your card — it places a pre-authorisation hold, typically equal to the insurance excess plus a tank of fuel. In Europe holds of €800–1,200 are normal, and if you decline the company's damage waiver, some agencies block considerably more. That money is frozen on your credit limit for the whole rental and can take up to 14 working days to release after you return the car.
Practical consequences: make sure your credit limit can absorb the hold plus your holiday spending, and never travel with a single card. If your card is declined for the hold amount, the desk's only alternative is usually selling you their full-coverage package at €25–40 per day.
Insurance: CDW, super CDW, and what voids all of it
Rental insurance abroad has three layers:
- Third-party liability — legally mandatory and included in every EU rental. Covers damage you cause to other people and property, not the rental car itself.
- CDW (Collision Damage Waiver) — usually included, but with an excess (deductible) of roughly €1,000–3,000. Crash the car and you pay the first €1,000–3,000 yourself.
- Super CDW / zero-excess cover — reduces the excess to zero, sold at the desk for a hefty daily fee, or far cheaper as a standalone excess-insurance policy bought online before your trip.
Here is the part most travellers miss: every one of those covers assumes you were legally allowed to drive. The terms and conditions of the major brands require the driver to hold a valid licence and any legally required permits. If local law or the rental contract required an International Driving Permit and you didn't have one, the insurer can treat you as an unlicensed driver — CDW, super CDW and even third-party claims can be refused, leaving you personally liable. A €49 document against a five-figure liability is not a hard calculation. You can apply for a permit online here; it takes about five minutes.
Cross-border driving and one-way fees in Europe
Inside the Schengen area there are no border checks, but your rental contract still draws lines on the map:
- Tell the agency before pickup if you plan to cross any border. Undeclared border crossings void your insurance and GPS trackers mean they will know.
- Cross-border fees typically run €20–60 for Western European crossings. Travel into Eastern Europe or non-EU countries often costs more and is limited to lower vehicle categories — premium German cars (BMW, Mercedes, Audi) are routinely banned east of Germany and Austria entirely.
- One-way rentals within a country are usually cheap or free between city branches. International one-ways (pick up in Paris, drop in Madrid) trigger recovery fees that can exceed €500–1,000 — sometimes more than the rental itself.
Driving beyond the rental country also raises the permit question again: your paperwork must satisfy every country you drive through, not just the one where you picked up the car. Our driving in Europe checklist covers the per-country document rules.
What the big brands actually check vs local agencies
At Hertz, Avis, Sixt and Europcar airport desks, the process is standardised: licence scanned, credit card name matched against the booking, passport recorded, hold placed. Whether they ask for your permit varies by country and even by agent — desks in Italy, Spain, Greece and Thailand ask far more often than desks in France or Germany. But do not confuse "the agent didn't ask" with "I didn't need it": the contract you sign states you hold all legally required documents, and that clause is what the insurer reads after an accident, not the agent's memory.
Local independent agencies are looser at the counter — some will rent on a debit card, a few skip the deposit — but the same insurance logic applies with less corporate backup and more room for disputes. The relaxed pickup is precisely what makes the return riskier (see scams below).
The desk agent not asking for a document does not make you legal. The contract you signed says you had it — and the insurer only checks after something goes wrong.
Common rental scams and how to beat them
- Fuel policy games. "Full-to-full" is the only fair policy. "Full-to-empty" prepays a tank at inflated prices and refunds nothing for what you leave. Photograph the fuel gauge at pickup and keep your last fuel receipt from a station near the return point.
- Phantom damage claims. The classic: a charge for a scratch appears weeks after you have flown home. Defence is simple and non-negotiable — photograph and video the entire car at pickup and again at return, timestamps on, including roof, wheels, windscreen and interior. Insist that pre-existing damage is written on the check-out form before you drive off.
- Desk-sold insurance pressure. Agents earn commission on super CDW. If you already bought excess cover online, say so once, decline firmly, and check the final contract line by line before signing — "accidental" additions are common.
- Unexplained card charges. Cleaning fees, admin fees for traffic fines, toll "service charges". Ask for an itemised invoice for any post-rental charge; card issuers side with you if the agency cannot document it.
Pickup checklist
- Physical driving licence (valid 1–2+ years)
- International Driving Permit if the country or contract requires one — get yours here before you fly
- Credit card in the main driver's name with room for a €800–1,200 hold
- Passport
- Printed booking voucher and excess-insurance policy
- Photos and video of the car, inside and out, before leaving the lot
Ten minutes of preparation at home removes almost every unpleasant surprise a rental desk can produce.
