Slovenia Drink-Drive Limit 2026: 0.05%, Zero If Under 21

Slovenia’s drink-drive limit is 0.05% for experienced drivers. That is lower than the 0.08% used in England and Wales and the same as Scotland’s. For two groups the limit is zero: drivers under 21, and anyone who has held a licence for less than two years. GOV.UK warns that being caught over the limit can bring a fine and possible imprisonment, and police can fine drink-drivers on the spot.

Who is in the zero group

The under-21 rule is easy to check. The second rule catches more British visitors than they expect, because it is about the licence, not the birthday. Someone in their thirties who passed their test last year counts as a new driver, and for them any measurable alcohol is an offence. If your full licence is less than two years old, plan the trip as if Slovenia had a zero limit for everyone.

0.05% against what you know from home

In England, Wales and Northern Ireland the limit is 80 mg of alcohol per 100 ml of blood. Slovenia’s 0.05% is the same line Scotland uses: 50 mg. A drink that would leave you under the limit at home can put you over it here. No one can tell you how many glasses that is for your body, weight and meal, which is why the cleaner rule is simply not to drink if you are driving. The morning after a long dinner counts too; alcohol does not clear on a schedule that suits an early start.

Licence and side of the road

A UK photocard licence is all you need: GOV.UK says you can drive in Slovenia on it, with no international permit. Hire companies may set stricter conditions of their own, such as a higher minimum age. If you take your own car, check whether it needs a UK sticker.

Slovenia drives on the right. The risky moments come early: a roundabout flowing the other way, a glance in the wrong direction at a junction, drifting into the wrong lane after a turn. Keep the first stretch to quiet roads rather than central Ljubljana or an alpine pass.

The vignette comes before the motorway

Motorways and expressways need an e-vignette, linked to your number plate and checked by camera rather than at booths. A car pays EUR 16 for seven days, EUR 32 for a month and EUR 117.50 for a full year. Buy it at a petrol station, a post office, a DARS office near the border, or online, using only the official DARS website. Motorhomes and other vehicles over 3.5 tonnes must instead register for DarsGo and collect a unit at a service point on first entry. Buying from the right site and avoiding a plate typo are covered in the Slovenia vignette guide.

If you break down on a motorway

GOV.UK sets out what to do:

1. Call 1970 for assistance (or +386 1 518 8 518) and switch on the hazard lights.
2. Everyone puts on a reflective jacket before leaving the car.
3. Place the warning triangle behind the vehicle and wait behind the safety barrier where you can.
4. In a tunnel, walk out towards the entrance you came in by.

A car stopped in a live lane, slip road or tunnel bay may be removed by the motorway operator’s contracted tow service. On the hard shoulder or in a rest area you can arrange your own recovery, but it normally has to be moved within 2 hours. Unauthorised recovery operators do approach stranded drivers and charge high fees; authorised ones carry the DARS logo.

Kit, lights and winter

Headlights stay on day and night, and the car must carry a warning triangle, reflective jacket and first-aid kit. From 15 November to 15 March, or whenever there is snow or black ice, cars need winter tyres on all four wheels, or summer tyres with snow chains in the boot, with at least 3 mm of tread. The fine is EUR 125, or EUR 417 if you also hold up traffic. Speed limits are 130 km/h on motorways (81 mph) and 50 km/h in towns (31 mph).

Call 113 for the police and 112 for an ambulance, fire or mountain rescue. The Slovenia driving guide has more, and the driving permit checker covers neighbouring countries.
