B. The splash guards:

1. Shall be attached in a manner that prevents the splashing of mud or water on the windshield of other motor vehicles.

2. Shall extend to a length of not more than eight inches from the ground.

3. Shall be wide enough to cover the full tread or treads of the tires being protected.

4. Shall be installed close enough to the tread surface of the tire or wheel to control the side throw of the bulk of the thrown road surface material.

5. May be constructed of a flexible rubberized material.

6. Shall be attached in a manner that, regardless of movement either in the splash guards or the vehicle, the splash guards retain their general parallel relationship to the tread surface of the tire or wheel under all ordinary operating conditions.

C. This section does not apply to:

1. A vehicle commonly known as a pickup truck with a manufacturer's rating of three-quarter ton or less, except that this section applies if the pickup truck has been modified from the original bumper height design to raise the center of gravity of the pickup truck.
