This invention is a splash and spray control shield for the wheels of large vehicles, such as trucks and trailers, and is designed to control the wet weather splash and spray generated by the centrifugal force of the forward rotation of the wheels of such a vehicle traveling over wet road surfaces. This shield consists of a unit with sidewalls that covers the uppermost forward part, over the top of and the uppermost rearward part of the wheel or dual wheels, or wheels of adjacent axles. The uppermost forward section of this shield consists of an air collector known as a "scoop"-which is aerodynamically designed to collect and direct the flow of air caused by the forward movement of the vehicle, across the top of, backwardly and downward, behind the wheel or wheels or most rearward wheels of a set of adjacent axles, directly to the road surface. This flow of air transports wet weather road surface material such as water, snow, salt, mud, pebbles, and the like, which usually emanates as splash and spray, on a downward direction and returns it to the road surfaces so as not to discharge it into adjacent traffic lanes. The front and rear of the wheel opening on each side of the shield is arcuately shaped in approximate conformity with the arcuacy of the wheel periphery and this wheel opening has a resilient extension which will increase its effectiveness and will provide ease in tire and wheel maintenance. A resilient shield extension is fastened to the lowermost rear section of the shield to aid in returning the wet weather mixture to the road surface.
