Winter tyre use is mandatory in Montenegro from today for vehicles travelling on roads with snow, ice or frost, or on sections covered by a specific order. The winter period runs until 1 April. Tyres used during this time must have at least 4 millimetres of tread pattern across the legal wear area. Under Montenegro’s Road Safety Law (ZOBS), drivers of passenger and freight vehicles in categories M and N can be fined 500 to 1,000 euros or jailed for up to 60 days if the vehicle lacks winter tyres on all wheels during winter conditions, or if it does not meet other winter equipment requirements. A separate fine applies for tread depth violations. Drivers who drive from 15 November to 1 April with tyre tread less than 4 mm face fines of 200 to 400 euros. Further penalties are set for vehicles missing winter equipment when an order is in force. In those cases, drivers face 150 to 300 euros. The law also sets fines for legal entities and their responsible representatives. Businesses can be fined 1,500 to 6,000 euros, responsible individuals inside the business can be fined 300 to 800 euros, and entrepreneurs face 300 to 3,000 euros. Traffic authorities said services are ready for the winter season, with the required machinery, workforce, equipment and materials planned for maintaining main and regional roads.
