Art. 29 Ordinance of September 5, 1979, on Road Signage (OSR) - Mandatory Snow Chains
OSR; Chapitre 3 Signaux de prescription
Art. 29 OSR · Mandatory Snow Chains
The sign "Mandatory Snow Chains" (2.48) means that multi-track motor vehicles may only use the section in question if at least two driving wheels on the same axle, or one per side in the case of twin wheels, are equipped with metallic snow chains; this provision applies, by analogy, to motor tricycles. Similar devices made from other materials, which are authorized by the Federal Roads Office (OFROU), are also permitted.
The sign will be removed as soon as good tires are sufficient to travel on the section.
The requirement indicated will be revoked by the sign "End of Snow Chain Requirement" (2.57).
