A. No vehicle shall be driven or moved on any street, highway or roadway unless such vehicle is so constructed or loaded as to prevent any of its load from dropping, sifting, leaking, blowing or otherwise escaping therefrom, except that sand may be dropped for the purpose of securing traction, or water or other substances may be sprinkled on a roadway in cleaning or maintaining such roadway.
B. No person shall operate on any street, highway or roadway any vehicle with any load unless the load and any covering thereon is securely fastened so as to prevent said covering or load from becoming loose, detached or in any manner a hazard to other users of the highway. Any vehicle loaded with sand, cinders or other loose material susceptible to blowing or otherwise escaping shall have such load covered so as to prevent the flowing or escaping of the load from the vehicle.
C. This section shall not apply to trucks loaded with livestock, poultry or agricultural products only, except bailed agricultural products; provided, that any such trailer shall be so constructed or loaded as to prevent such livestock or poultry from escaping therefrom. (2001 Code § 72.08)
