The Commissioner of Public Safety is hereby authorized, empowered and directed to adopt and promulgate rules and regulations establishing standards and specifications for the design, materials and mounting of a standard slow-moving-vehicle emblem and high intensity reflectorized tape for the uniform identification of slow-moving vehicles.
