  1. No vehicle shall be operated or moved on any highway unless it is so constructed, maintained, and loaded as to prevent its contents from dropping, sifting, leaking, or otherwise escaping.

  2. The loads of all trucks, trailers and semi trailers carrying gravel, sand, coal or other nonagricultural and non-forestry products on interstate, primary, or secondary highways or roads maintained by cities, counties or incorporated towns shall be either (i) secured to the vehicle in which they are being transported or (ii) covered. Covers used to prevent the escape of material from commercial vehicles used to transport solid waste shall be of such design, installation, and construction as to contain the vehicle's cargo within the vehicle, regardless of the vehicle's speed or weather conditions. Public service company vehicles, pickup trucks, and emergency snow removal equipment while engaged in snow removal operations shall be excluded from the provisions of this subsection.
