(a) A vehicle, except a commercial vehicle carrying logs or tubular products, shall not be driven or moved on a highway unless the vehicle is so constructed or loaded as to prevent its contents from dropping, shifting, leaking, blowing off or otherwise escaping therefrom. The tailgate, faucets and taps shall be securely closed to prevent spillage during transportation, whether loaded or empty, and the body of the vehicle shall not have any holes or cracks through which material can escape. Any highway maintenance vehicle engaged in either ice or snow removal shall be exempt from this section.
(b) Actual spillage of material on the highway or proof of that spillage is not necessary to prove a violation of this section.
(c) A commercial vehicle carrying a load, other than logs or tubular products, which is not completely enclosed, shall either:
(1) Have the load covered with firmly secured canvas or a similar type of covering. A device used to comply with this requirement shall not exceed a width of 108 inches nor by design or use have the capability to carry cargo by itself.
(2) Have the load securely fastened to the body or the frame of the vehicle with binders of adequate number and of adequate breaking strength to prevent the dropping off or shifting of the load.
(d) A company or individual who loads or unloads a vehicle or causes it to be loaded or unloaded with knowledge that it is to be driven on a public highway, in a manner as to cause a violation of subsection (a) hereof, shall be prima-facie liable for a violation of this section.
(e) A person shall not operate a motor vehicle carrying logs or tubular products on a highway unless the following conditions are complied with:
(1) If the logs or tubular products are loaded crosswise or at right angles to the side of the vehicle, the logs or tubular products shall be securely fastened to the body or frame of the vehicle with not less than two binders which are secured to the frame at each end of the load and pass over the load so that the frame and binders completely encircle the load.
(2) If the vehicle is a truck or trailer carrying logs, which vehicle has a loading surface more than thirty-three feet in length, and the logs are loaded crosswise or at right angles to the side of the vehicle, the vehicle shall be equipped with a center partition located approximately one-half the distance from the front to the rear of the loading surface of the truck or trailer. The center partition shall be either a center mounted hydraulic loader or a center set of stakes and shall be pinned, bolted or otherwise securely fastened to the frame. The load shall be secured as required by paragraph (e)(1) hereof and, in addition, the two lengthwise tiedowns shall be attached or threaded through the center partition at a level not less than one foot below the load height.
(3) If the logs or tubular products are loaded lengthwise of the vehicle, obliquely or parallel to the sides, with metal stakes and pockets, the load of logs or tubular products shall be secured as follows:
A. With two tiedowns from frame to frame for every tier.
B. So that not more than one-half the diameter of the top log or tubular product extends higher than the stake tops.
C. With two cross chains per tier if the load extends more than five feet above the loading surface.
D. So that every ten linear feet, and any remaining fraction thereof, has not less than one tiedown from frame to frame.
(4) If the logs or tubular products are loaded lengthwise of the vehicle, obliquely or parallel to the sides, with permanent metal gusseted bunks, the load of logs or tubular products shall be secured as follows:
A. With two tiedowns from frame to frame for every tier.
B. So that not more than one-half the diameter of the top log extends higher than the stake tops.
C. So that every ten linear feet, and any remaining fraction thereof, has not less than one tiedown from frame to frame.
(5) The tiedowns, cross chains, stakes and other materials used to secure loads of logs or tubular products, as required under paragraphs (e)(1) through (e)(4) hereof, shall meet the following minimum requirements:
A. Chain shall be of steel and shall be of a strength not less than five-sixteenths of an inch in diameter "transport," which is embossed with a grade stamp representative of grade 70, or not less than three-eighths of an inch in diameter "high test," which is embossed with a grade stamp representative of grade 40. Chain shall not be repaired by welding, wire or cold shuts.
B. Wire rope shall be of improved plow steel and not less than three-eighths of an inch in diameter.
C. Webbing strap shall be not less than three inches in width and shall have a minimum breaking strength of 14,000 pounds.
D. Metal stakes shall be of sufficient strength to hold and contain the load.
E. Connecting links and hooks shall be at least as strong as the tiedown material used.
(f) Subsection (c) hereof shall not apply to a person operating a vehicle to transport agricultural commodities in the normal operation of a farm. However, a person operating a vehicle to transport agricultural commodities in the normal operation of a farm, who violates subsection (a) or (d) hereof, is guilty of a misdemeanor and shall be subject to the penalty provided in Section 486.99(a).
(g) Paragraph (c)(1) hereof shall not apply to a motor vehicle transporting items of a load which, because of their weight, will not fall off the moving vehicle and which have their centers of gravity located at least six inches below the top of the enclosure, nor to a motor vehicle carrying metal which, because or its weight and density, is so loaded as to prevent it from dropping or falling off the moving vehicle.
(h) Paragraph (c)(1) hereof shall not apply to motor vehicles and other equipment engaged in work upon the surface of a highway or street in a designated work area.
(i) As used in this section:
(1) "Cross chain" means a chain which extends through the load of logs or tubular products and is connected at each end to a side stake.
(2) "Logs" means sawlogs, pulpwood or tree-length poles.
(3) "Tiedown" means a high-strength material which is used to secure the load of logs or tubular products to the frame or the bed of the vehicle.
(4) "Tier" means a vertical pile or stack of logs or tubular products.
