In the Grand-Duchy of Luxembourg, driving a motor vehicle on public roads in winter conditions (black ice, packed snow, slush, ice sheets or frost) is permitted only with regulation winter tyres (winter tyres or all-weather tyres marked "M.S.", "M+S", "M&S" or the alpine symbol) mounted on all wheels of the vehicle.

This regulation applies to all drivers, regardless of the country of registration of the vehicle. Non-observance is punishable by a 74-euro fine. However, this does not apply to vehicles parked on public roads.

For lorries, coaches and buses, winter tyres on all driving axles is sufficient. The same applies to motor homes with a maximum authorised mass exceeding 3,500 kg.

This requirement does not apply to mopeds, motorcycles, tricycles, lightweight quadricycles, quadricycles, tractors and self-propelled machinery. It is also not applicable to certain categories of vehicles, provided that winter tyres do not exist by design for these categories, namely:

• special vehicles other than motor homes;
• vehicles used by the Army, the Grand-Ducal Police, the Customs and Excise Agency, the Emergency Services Administration and the communal fire and rescue services.
