Usually yes, but only with declared permission, the right fee structure and a car that is cleared for every country on your route. Here are the rules, costs and exclusion lists that decide it.
Yes, you can usually take a rental car across borders in Europe, but only if you declare every country you plan to enter and pay a cross-border fee, typically 20 to 50 euros. Cross undeclared and you breach the rental contract, which can void your insurance for the entire trip, not just the part abroad.
The fee itself is rarely the problem. The structure of it is what catches people out, because two companies collecting a similar amount can price it in completely different ways.
Hertz at Berlin Tegel has charged a flat 47.60 euros for the right to drive out of Germany into another permitted country. Enterprise, on rentals starting in Germany, has used a different model: 5 euros per day, capped at 50 euros. On a four-day Munich to Salzburg loop that is 20 euros against Hertz's 47.60. On a two-week Alpine trip the cap kicks in and the two end up almost identical.
So the question to ask at booking is not "how much is the cross-border fee", it is "is it per day, per country, or per rental, and is it capped". A per-country charge on a route through France, Switzerland, Italy and Austria adds up fast, and it is the one structure people forget to check.
Declare it at the point of booking rather than at the desk. Some branches simply will not add cross-border permission at pickup if the car in front of you is not cleared for it, and by then you have no time to rebook.
Fees only apply where travel is permitted. Every major company also runs a hard exclusion list, and it is longer than most people expect.
The reliably restricted cluster across the big brands is the non-EU east and parts of the Balkans: Albania, Belarus, Bosnia and Herzegovina, Kosovo, Moldova, Russia, Serbia, Turkey and Ukraine. Beyond that, published lists genuinely differ, and they differ by pickup branch as well as by brand. Some Hertz lists have included Bulgaria, Greece, Latvia, Lithuania and Romania; others have added the Czech Republic, Hungary, Poland and Slovakia. Do not assume EU membership means automatic permission.
This matters enormously at the route-planning stage. A Croatia trip that dips into Bosnia to reach Dubrovnik, or a Baltic run that crosses into Kaliningrad, can be blocked outright rather than surcharged. Check the exclusion list before you commit to the shape of the route, not after.
This is the restriction almost nobody plans for. Approval frequently depends on the vehicle, not just the destination.
Hertz has barred all Mercedes and BMW models, convertibles, SUVs and its Prestige and Fun Collection cars from being driven into or dropped off in Italy. Sixt has restricted Jaguar, Maserati, Land Rover and Porsche models, along with its luxury classes generally, to Zone 1 countries only. Enterprise has excluded Audi, BMW, Mercedes, Volkswagen, Land Rover and Jaguar from certain destinations.
Most road trips need two to three months of planning, but national parks, ferries and peak dates can need six. Here is a realistic timeline for what to book and when.
The practical consequence is that a free upgrade at the counter can quietly cancel your route. If you are offered a bigger or smarter car, ask whether it is cleared for every country on your itinerary before you accept the keys.
Land borders and water crossings are treated as different things in most rental contracts, and cover that works on a bridge can evaporate on a boat.
Thrifty has permitted only land crossings, meaning bridge, tunnel or road. Hertz has specifically prohibited taking its cars on the Italy to Croatia ferry. Island hops are often excluded outright, largely because recovering a broken-down vehicle from an island is expensive.
If your route includes a ferry, a Greek island, Sardinia, Corsica or the Balearics, treat it as its own approval question and get the answer in writing on the rental agreement.
Once cross-border travel is approved, the rental company supplies the vehicle-side paperwork, including Green Card insurance documentation where the route requires it. Your side of it is the driver-side paperwork, and that is on you.
UK drivers should check whether an International Driving Permit is needed for any country on the route, because it is required in some and not others. GOV.UK also flags equipment rules that catch out visiting drivers: a reflective jacket and warning triangle are mandatory in many European countries, and several cities require emission stickers to enter low-emission zones. A rental car picked up in France will not automatically be equipped for a German Umweltzone.
The broader document picture for UK-registered travel is worth a separate read, and we have covered it in what documents you need to drive in Europe from the UK.
The mistake is treating this as a booking-day admin task. It is a route-design constraint, and it belongs at the same stage as your tolls and driving-hours planning.
Three things to settle before you fix the itinerary. First, list every country the route touches, including ones you only clip for an hour. Second, confirm the exclusion list and the fee structure for that specific pickup branch. Third, check whether the trip is genuinely a one-way international rental, because approval to drive across a border is not the same thing as approval to leave the car in another country, and international one-way drops carry their own separate fees and restrictions.
While you are at it, price the tolls and vignettes for the same country list, since they follow exactly the same route logic. Our guide to road trip tolls in Europe covers which countries need a sticker bought in advance.
And if the fees, restrictions and vehicle-class rules are stacking up, it is worth re-running the basic decision of whether to rent or take your own car. For a multi-country European trip from the UK, the cross-border surcharge is often the smallest line in that comparison, but the exclusion lists can be the deciding one.
The rule that matters is simple. Ask before you book, get the approved countries written onto the rental agreement, and never assume the open border you drive through is also open in your contract.
Two nights per stop is the sensible default, but not every stop deserves the same. A practical rule for assigning nights to each place on a multi-stop road trip.
