As there is no real highway in Montenegro; most roads are two-lane only, with frequent addition of a third overtaking lane, and generally are not up to European standards. Most roads are curvy and mountainous, so speeds over 80 kph (50 mph) are rarely legal, and rarely safe.
As in the rest of Europe, traffic drives on the right in Montenegro. The two major roads are the Adriatic motorway from Igalo to Ulcinj and the motorway linking the north and the south, from Pertovac to Bijelo Polje via Podgorica and Kolasin. Driving at night is not advisable, owing to the poor condition of the roads. There are several tollbooths along the motorways. Foreign-registered vehicles are charged at a higher toll then local vehicles. The toll also depends on the size of vehicle. Drivers should take plenty of euros to pay in cash at the booths. The two-lane Moraca Canyon is a notoriously bad road and should be avoided when possible.
Speed limits are 120 kph (75 mph) on motorways and 100 kph (62 mph) on other roads.
The use of safety belts and headlights during the day is compulsory, and the use of cellphones while driving is prohibited. Signposts used in Montenegro are almost identical to those used in EU countries.
Local drivers tend to drive fast, and to get involved into dangerous over-takings. Traffic jams are common during the peak of the summer season. Pedestrians are notorious for jaywalking in every Montenegrin city.
Drivers tend to be extremely vocal, so don’t take it personally if a driver yells at you.
International Driving Licence is required. No customs documents are required but car log books, a Green Card, vehicle registration/ownership documents and a locally valid insurance policy are necessary.
