Montenegro on a UK Licence — Side Switch & a 0.03 Limit That Bites

Montenegro is an easy sell for a British road trip — short flights, the drama of the Bay of Kotor, mountain passes behind a coastline that looks airbrushed. Two adjustments do most of the work in keeping you out of trouble, and one of them is the kind of thing that turns a good holiday into a legal problem.

The drink limit is the trap, not the speed

At home you drive to a 0.08 limit (in England, Wales and Northern Ireland). Montenegro runs 0.03 — under half, near enough a third. That gap matters because the British habit of a pint or a glass of wine with lunch and then driving on simply doesn’t survive the maths here. There is no comfortable margin: if you’re driving, don’t drink. Enforcement is genuine along the coast through summer, and penalties stretch to roadside fines and licence confiscation.

You’ll also be on the other side of the road

The UK drives on the left, Montenegro on the right. Your sharpest risk is the first day — pulling out of a forecourt, joining a roundabout that now flows clockwise the other way, the reflex look over the wrong shoulder. Spend your opening hour on quiet roads rather than diving straight into Kotor’s seafront. After that it settles quickly, but stay deliberate at every junction until it does.

Licence and paperwork

Your UK licence covers stays of up to 12 months, so it’s good for any holiday. An IDP is recommended — not strictly required, but it heads off disputes with rental firms and police, who expect to see one. Carry it with your licence and passport. You can only get the permit in the UK, so sort it before you fly; our driving permit checker confirms exactly what your corridor needs.

The roads themselves

Limits read 50 / 80 / 130, but the coastal routes are narrow and winding, with blind bends and single-bore tunnels where you take turns. July and August jam the Budva–Kotor stretch solid. Drive to the corner, not the number. A 10 km/h overshoot runs EUR 30-80 paid on the spot, fuel is about $1.52/litre, and the emergency line is 112.
