Winter equipment is mandatory from 15 November until 15 March and whenever there are winter weather conditions (for example, at times of snowfall, blizzards or black ice).
Private cars and vehicles up to 3.5 tonnes must be equipped with winter tyres on all 4 wheels, or summer tyres on all 4 wheels plus snow chains in the car boot. The minimum tyre tread depth must be 3mm. Vehicles over 3.5 tonnes must have winter tyres on the driving wheels or summer tyres on all 4 wheels plus snow chains in the car boot.
You can be fined 125 Euros for not having this equipment, or 417 Euros if you cause a delay on the road for the same reason. The regulations apply to all vehicles. For more information, please see the website of the Automobile Association of Slovenia, under touring information, special regulations.
By law, you must have your headlights on at all times, while driving in Slovenia. You are also required to carry a reflective jacket, a warning triangle and a first aid kit in the vehicle. If you intend to hire a car and drive it into Slovenia you must declare this to the car hire company first, as you must have adequate car insurance cover. Heavy on-the-spot fines are in place for traffic offences and jaywalking. The police are empowered to impose on-the-spot fines for offences including speeding, driving under the influence of alcohol and for using mobile phones without properly installed wireless headsets (Bluetooth).
