A practical driving guide for taking a Montenegro rental car across the border. The rental side, including the Green Card and cover, is arranged at booking; this page covers the driving itself: the International Driving Permit, tolls and vignettes, what to carry, drive times, and the documents to have ready at the crossing.
Permission to cross the border is part of your booking, not something arranged on the road. The Green Card for the Balkans covers the insurance side; everything below is about the drive.
Most EU, EEA, and UK licences are accepted across all five neighbouring countries without an International Driving Permit. If your licence was issued elsewhere, or is not printed in the Latin alphabet, carry an IDP alongside the original. It is issued by your home licensing authority before you travel and is inexpensive, so it is worth arranging if there is any doubt.
None of the five neighbouring countries use a motorway vignette, the windscreen sticker that countries like Slovenia, Austria, and Switzerland require. What they have instead are tolls on some motorways: Croatia and Serbia charge tolls on their motorway networks, paid at booths or by electronic tag, Bosnia has tolls on a few sections, and Montenegro charges a small toll for the Sozina tunnel on the Podgorica to Bar road. Albania and Kosovo are largely toll-free. The exception is the wider EU and Switzerland route, where Switzerland and several EU countries do require a vignette, and buying it is the driver's responsibility.
Limits are signposted and broadly similar across the region: roughly 50 km/h in towns, 80 to 90 on open roads, and 110 to 130 on motorways. Dipped headlights are expected during the day in several countries, seat belts are required for everyone, and drink-driving limits are low to zero. Enforcement is by spot checks, so keep your documents to hand.
Across the region, cars are generally expected to carry a warning triangle, a reflective hi-vis vest, and a first-aid kit. Rental cars usually come equipped with these, but it is worth checking at pickup. In winter, some inland and mountain routes require winter tyres or chains, so ask about winter equipment if you are travelling in the colder months.

Petrol and diesel are widely available on the main routes, but stations can be sparse on remote mountain roads, so fill up before long inland stretches. Cards are accepted at most stations and toll booths, though it is worth keeping some local cash for smaller rural stations and minor tolls.
The nearest crossings, into Croatia, Bosnia, and Albania, are only a couple of hours from the Montenegro coast, while Serbia and the deeper EU routes are full-day drives. The destinations overview lists the distance and approximate drive time to the main city in each country from a Montenegro pickup, and each country guide goes into the specific route.
Have your original rental agreement showing the destination as an approved country, your passport, and your driving licence ready at the crossing. On the routes that require it, officials may also ask to see the Green Card, which is part of your documentation.
