Crossing Borders in a Rental Car: Rules, Restrictions and What to Ask
Can you cross borders in a rental car in Europe? Which countries need written permission, where insurance stops working, and the exact questions to ask before your trip.
Crossing a border in a rental car is straightforward within the EU. Outside it, the rules change sharply. The wrong assumption — that your insurance and permission automatically follow you wherever you drive — leads to voided cover and large charges. Here is what applies where.
Within the EU and Schengen Area
No separate permission needed. All major rental companies allow free movement across EU member states and most Schengen countries as part of their standard contract. You do not need to notify the supplier before crossing from Spain into France, Italy into Slovenia, or Germany into Austria.
Insurance stays valid across the EU automatically under EU motor insurance directives. Third-party liability cover follows the car regardless of which EU country it is in.
What to confirm: if you are renting from a local or independent supplier rather than an international brand, check the contract. Some budget local operators in southern Europe do restrict cross-border use even within the EU.
Non-EU countries that require written permission
Outside the EU, most rental contracts require explicit written authorisation before you can legally cross the border. Without it, you are technically in breach of contract from the moment you enter the unauthorised country.
| Country | Permission required? | Additional documents |
|---|---|---|
| Bosnia-Herzegovina | Yes | Green Card |
| Montenegro | Yes | Green Card |
| Serbia | Yes | Green Card |
| Albania | Yes | Green Card; some companies refuse entirely |
| North Macedonia | Yes | Green Card |
| Kosovo | Often refused | Many companies exclude Kosovo entirely |
| Turkey | Yes | Green Card; some companies refuse |
| Morocco | Yes | Very few companies allow; specialist required |
| Ukraine | Yes | Most companies currently exclude Ukraine |
| Georgia | Yes (most companies allow) | Green Card; confirm before booking |
| Armenia | Yes (many allow) | Green Card |
| Belarus | Almost always excluded | |
| Russia | Excluded universally |

The Green Card explained
The Green Card (International Motor Insurance Certificate) is a standardised document proving that the car carries third-party liability insurance valid in the country being visited. It is named after the green paper it was historically printed on.
For rental cars, the supplier issues the Green Card when cross-border travel is authorised. It lists the countries where coverage applies. If a country is not listed, driving there is uninsured for third-party liability.
How to get it: ask the rental company when you book or at pickup. It is not automatic — you must request it. Most companies issue it at no charge when the crossing is permitted.
What it covers: third-party liability only. It does not extend CDW or damage protection to the new country. Damage to the rental car in an unauthorised country is at your expense.
The Neum corridor and Pelješac Bridge (Croatia / Bosnia)
The historic A1 motorway from Split to Dubrovnik passed briefly through Bosnia at the Neum strip. This required a Green Card for Bosnia-Herzegovina and caused complications for rental car agreements.
The Pelješac Bridge, opened July 2022, now provides an uninterrupted Croatian road connection from Split to Dubrovnik entirely within Croatia. The Neum crossing is no longer necessary for the standard A1 route.
If your itinerary includes Mostar, Sarajevo or anywhere in Bosnia proper, the permission and Green Card requirement still applies.
What to ask before you book
For any trip that crosses or approaches a non-EU border:
- Is [country] listed as an authorised destination in the contract?
- Can you issue a Green Card for [country]?
- Are there any restrictions on the car category for this crossing? (Some companies restrict which vehicles can cross into certain countries)
- Is there an additional daily fee for cross-border authorisation?
- What is the process if the car breaks down or is damaged in that country? (Roadside assistance may not operate outside permitted areas)
Get the answers in writing — either in the booking confirmation or as a separate email from the supplier before pickup.
Turkey: a common source of problems
Turkey is one of the most frequently visited non-EU destinations by car from Greece or Bulgaria. It is also one of the most commonly restricted.
Most major international companies (Hertz, Avis, Europcar, Sixt) do not authorise Turkey crossings in standard contracts. Some require booking a specific “Turkey crossing” rate. Local suppliers at Istanbul or Ankara airports are a different matter — they rent domestically without issue.
If your itinerary involves driving from Greece into Turkey, confirm permission before booking the car. Do not assume the crossing is possible on a standard Greek rental.

Morocco: effectively off-limits for standard rentals
Most Spanish and Portuguese rental companies prohibit Morocco crossings entirely. The few that allow it require:
- A specific Morocco-authorised rate
- A Green Card valid for Morocco
- Temporary vehicle import documentation at the Moroccan border
The practical alternative for Morocco travel: cross as a foot passenger (Tarifa to Tangier takes 35 minutes) and rent a car in Morocco locally. See car rental in Morocco.
Insurance validity across borders
Your CDW and TPL cover may behave differently when authorised cross-border travel is permitted:
- TPL: follows the Green Card. Valid in listed countries.
- CDW: covers the rental car in authorised countries only. An accident in an unlisted country = full damage liability at your expense.
- Theft: some contracts restrict theft cover outside the home country.
Always check the insurance section of the rate conditions, not just the permitted countries list. The two do not always align.
