Can a British Driver Use Their Licence in Bulgaria? — IDP Recommended + the Side Switch

Bulgaria is one of the cheapest corners of the EU to hire a car, with fast motorways linking Sofia to the Black Sea coast. For a British driver the licence is the easy part — it is the side of the road and a small purple sticker that actually trip people up.

The verdict for a UK licence holder

Your British licence is accepted in Bulgaria, and an International Driving Permit is recommended since the UK left the EU. It is rarely demanded, but it removes any argument at a roadside check, so carry the IDP with your licence and passport. Arrange the IDP in the UK before you travel.

The side switch comes first

The UK drives on the left; Bulgaria drives on the right. This is the adjustment most likely to catch you out, and the risk window is your first day — joining a roundabout (now anticlockwise), pulling out of a fuel station, or a reflex glance the wrong way. Take your first hour on quiet roads rather than central Sofia, and stay deliberate at every junction until it feels natural.

You must buy a vignette before you drive

Bulgaria charges for its main roads through an electronic vignette, and there is no physical sticker to fix — you register your number plate online or at a border kiosk. Buy it before you pull onto a national road or motorway: driving without one is a fineable offence, and rental cars are not always pre-loaded with it, so check with the desk. Our vignette countries guide explains how the system works across the region.

Speed, alcohol and surfaces

Motorways run up to 140 km/h, rural roads 90 and towns 50, with the drink-drive limit a strict 0.05 BAC — lower than home, so keep it to none. Cameras and patrols are common, and a 10 km/h overspeed costs around EUR 25.56 (≈ €25). Away from the motorways, surfaces get rough fast, so drive to the road rather than the sign.

Bulgaria adopted the euro on 1 January 2026. Figures previously published in leva were converted at the fixed statutory rate of 1.95583 leva to the euro.00 to the euro.
