In Belarus, when participating in road traffic from December 1 to March 1, vehicles must be equipped with winter tires on all wheels, with the same tread pattern on one axle. This requirement does not apply to trucks over 3.5 tons, nor to buses over 5 tons.
Winter tires are tires that have both of the following markings simultaneously: 1. A mountain peak symbol with three peaks and a snowflake inside, 2. One of the symbols "M+S", "M&S", "M S".If BOTH of these symbols are present on the marking, such tires are considered winter tires, even if they have any additional designations (+ All Season; Road+Winter (R+W); Any Weather, etc.)
During operation, winter tires must have a residual tread depth of at least 4 mm.
For participating in road traffic in winter on summer or worn-out tires, there is administrative liability: a warning or a fine of up to 1 B.V. (42 rubles), and for a repeat offense within a year – from 2 to 5 B.V. (84–210 rubles). If such a violation leads to the creation of an emergency situation or a road traffic accident, a significantly higher fine is provided, with the possible deprivation of the right to drive.
