Every towed vehicle shall be coupled to the towing vehicle by means of a safety chain, cable, or equivalent device in addition to the primary coupling device, except that such secondary coupling device shall not be necessary if the connecting device is connected to the towing vehicle by a center-locking ball located over or nearly over the rear axle and not supported by the rear bumper of the towing vehicle. Such secondary safety connecting devices shall be of sufficient strength to control the towed vehicle in the event of failure of the primary coupling device. The provisions of this Subsection shall not apply to wreckers towing vehicles or to vehicles secured to the towing vehicle by a fifth-wheel type connection.

Permits for the operation of such vehicles equipped with sirens or blue lights shall be in writing and shall be issued and may be revoked by the chief of an organized fire department, organized ambulance association, or rescue squad and no person shall use or display a siren or blue lights on a motor vehicle, fire, ambulance, or rescue equipment without a valid permit authorizing the use. Permit to use a siren or lights as heretofore set out does not relieve the operator of the vehicle so equipped with complying with all other traffic laws and regulations. Violation of this Section constitutes a class A misdemeanor.

C. 
In any action to recover damages arising out of the ownership, common maintenance or operation of a motor vehicle, failure to wear a safety belt in violation of this Section shall not be considered evidence of comparative negligence. Failure to wear a safety belt in violation of this Section may be admitted to mitigate damages, but only under the following circumstances:
1. 
Parties seeking to introduce evidence of the failure to wear a safety belt in violation of this Section must first introduce expert evidence proving that a failure to wear a safety belt contributed to the injuries claimed by plaintiff;
2. 
If the evidence supports such a finding, the trier of fact may find that the plaintiff's failure to wear a safety belt in violation of this Section contributed to the plaintiff's claimed injuries, and may reduce the amount of the plaintiff's recovery by an amount not to exceed one percent (1%) of the damages awarded after any reductions for comparative negligence.
D. 
Each person who violates the provisions of Subsection 2 of this Section after July 1, 1987, shall be guilty of an infraction for which a fine not to exceed ten dollars ($10.00) may be imposed.

When traveling in the rear seat of a motor vehicle the child shall be protected by either a child passenger restraint system approved by the Department of Public Safety or the vehicle's seat belt. When the number of child passengers exceeds the number of available passenger positions, and all passenger positions are in use, remaining children shall be transported in the rear seat of the motor vehicle. The provisions of Sections 210.104 to 210.107, RSMo., shall not apply to motor vehicles registered in another State, or to a temporary substitute vehicle.

Tractors, traction engines and similar vehicles may be operated which have upon their road wheels "V" shaped, diagonal or other cleats arranged in such manner as to be continuously in contact with the road surface if the gross weight on the wheels per inch of width of such cleats or road surface, when measured in the direction of the axle of the vehicle, does not exceed eight hundred pounds.
B. 
No tractor, tractor engine, or other metal-tired vehicle weighing more than four tons, including the weight of the vehicle and its load, shall drive onto, upon or over the edge of any improved highway without protecting such edge by putting down solid planks or other suitable material to prevent such vehicle from breaking off the edges of the pavement.
C. 
Any person violating this Section, whether operating under a permit or not, or who shall willfully or negligently damage a highway, shall be liable for the amount of such damage caused to any highway, bridge, culvert or sewer, and any vehicle causing such damage shall be subject to a lien for the full amount of such damage, which lien shall not be superior to any duly recorded or filed chattel mortgage or other lien previously attached to such vehicle; the amount of such damage may be recovered in any action in any court of competent jurisdiction, in the name of the State, by the municipality, county or other civil subdivision or interested party.
