Safety on Slovak roads during winter is an issue that local authorities (Policajný zbor) pay particular attention to. Unlike the more lenient regulations in some Western European countries, Slovakia applies rigorous standards regarding tire condition.
Official winter period in Slovakia:
November 15 – March 15
Mandatory winter tires when winter road conditions occur.
Winter Tire Regulations: What You Need to Know?
Slovakia applies a so-called situational obligation for passenger cars (M1 category). Drivers must have appropriate tires if there is snow, ice, or slush on the road surface.
Important for fleets: Trucks over 3.5 tonnes and buses must have winter tires from November 15 to March 15, regardless of weather.
Technical Requirements: Tread and Symbols
1. Minimum Tread Depth – 3 mm
While some countries allow 1.6 mm, the Slovak standard for passenger cars is 3 mm.
2. M+S and 3PMSF Markings
Tires must have M+S markings. By 2026, the snowflake-on-mountain symbol (3PMSF) is the recommended standard for high-performance safety.
