The Slovenian Road Safety Agency advises drivers to switch to winter tires based on ambient temperatures rather than waiting for the statutory deadline of November 15. While the law mandates winter equipment between November 15 and March 15, the agency emphasizes that summer tires lose their performance advantages once temperatures drop below seven degrees Celsius. Early tire changes are particularly recommended for those driving in higher elevations or using heavily worn tires close to the legal minimum tread depth of 1.6 millimeters. The report highlights the danger of black ice, which forms around freezing points and is nearly invisible on roads, bridges, and shaded areas. Drivers are advised to purchase new winter tires before the tread depth falls below three millimeters and to check other vehicle systems such as lights and wipers.
