Montenegro on an Irish Licence — The Side Switch & a 0.03 Limit

For Irish visitors the Bay of Kotor and the coast road south to Budva are the draw, and a hire car is the only way to do them on your own schedule. The paperwork barely registers — what changes everything is which side of the road you sit on.

Ireland drives on the left. Montenegro drives on the right, and that is the one thing most likely to catch an Irish driver out. The danger window is the first day: pulling out of a fuel station, taking a roundabout that now turns the other way, or that instinctive glance to the wrong side at a junction. Collect the car somewhere quiet, not in central Podgorica, and stay deliberate at every turn until the habit flips. The licence side of things is genuinely easy — your Irish photocard is valid here for stays up to 12 months with no International Driving Permit needed, so there is nothing extra to arrange before you fly.

The coast is the other thing worth bracing for. Montenegro scores as moderate to drive: the scenery is spectacular but the roads earning it are narrow, cut into cliffs, and threaded with single-bore tunnels where oncoming traffic, tour coaches and the odd cyclist all share very little space. The Sozina tunnel and the E65 coastal road see the heaviest summer congestion and the most police radar. Take the bends at the posted 80 km/h rural limit rather than chasing it, and expect the drive from Kotor to Budva to take far longer than the map distance suggests.

On alcohol, Montenegro is stricter than home. The limit is 0.03, against Ireland’s 0.05, and enforcement spikes in the tourist resorts over summer. There is no useful margin here — leave the car if you are drinking. Speeding 10 km/h over typically costs EUR 30-80 on the spot, rising to EUR 60-200 plus penalty points at 20 over, paid there and then with cash or card. If you do pick up a ticket abroad, our guide on who actually pays driving fines abroad explains how rental companies pass them on.

Before you set off, read the full rules on our Montenegro driving guide, and if you want to sanity-check a penalty, the Speeding Fine Calculator will give you a figure. The emergency number is 112, fuel runs around EUR 1.40 a litre, and the car should carry a warning triangle and reflective vest.
