(1) Farm machinery with tires having protuberances which will not injure the highway; and
(2) Tire chains of reasonable proportions or tires equipped with safety metal spike studs upon any vehicle when required for safety because of snow, ice, or other conditions tending to cause a vehicle to skid.
(d) The transportation board and local authorities in their respective jurisdictions may in their discretion issue special permits authorizing the operation upon a highway of traction engines or tractors having movable tracks with transverse corrugations upon the periphery of such movable tracks, or of farm tractors or other farm machinery, the operation of which upon a highway would otherwise be prohibited under this Code section.
