Montenegro for US Drivers 2026: A 0.03% Limit, Narrow Roads
United States
Montenegro
Americans stay on the right in Montenegro, but the alcohol limit is 0.03% against the US 0.08. Carry an IDP with your US license; coast roads are narrow and slow in summer.
Montenegro's 0.03% alcohol limit is less than half the US 0.08 standard, and UK travel advice says police can fine drivers from 10 km/h over the limit. Carry an IDP from AAA alongside your US license.
Montenegro feels familiar to an American behind the wheel: you stay on the right, and the road furniture is recognisable. Two numbers separate it sharply from driving back home, and the first is the one most likely to land an American in trouble.
From 0.08 to 0.03
The American 0.08 standard gives most drivers room for a drink with dinner. Montenegro’s Law on Road Traffic Safety treats a driver as under the influence above 0.3 g/kg, a 0.03% limit, close enough to zero that a single beer can carry you over. Police run roadside breath checks along the coast in summer, and UK travel advice puts traffic penalties anywhere from EUR 20 to EUR 6,000. The clean rule is no alcohol on any day you intend to drive.
Carry the IDP
Bring an International Driving Permit alongside your state license and passport. The US and Montenegro are both parties to the 1949 Geneva Convention, and that is the format of the IDP issued in the States by AAA, so it serves as the recognised translation of your license at a police stop or rental desk. Get it before you fly, and confirm your case with the driving permit checker.
Roads that look fast but aren’t
The 130 km/h (about 80 mph) motorway limit is real but rarely usable; ordinary roads outside towns are limited to 80 km/h and towns to 50 km/h. The driving that draws people here, the Bay of Kotor and the serpentine climb to Lovćen, runs on narrow, tunnel-heavy roads with tight bends, and July and August add heavy congestion. Police can fine you for 10 km/h over the limit, and excessive speeding can mean your license is confiscated on the spot; if a ticket follows you home, the guide to who pays fines abroad explains how.
The car must carry a warning triangle, a reflective vest and a first-aid kit. Between 15 November and 1 April, winter tyres with at least 4 mm of tread are compulsory whenever snow, ice or frost is on the road. Emergencies are 112. The full ruleset sits in the Montenegro driving guide.
