Abstract: Sectional spray collector arched shields are mounted above a vehicle wheel and extend around approximately one-eighth to one-half of the vehicle wheel circumference. Each shield includes adjacent, downwardly flaring collector channels running circumferentially of shield. The collector channels have apertures in their crests and the aperture marginal portions are formed by flanges to divert the spray into troughs between adjacent collector channels. Water from the troughs is collected in runoff gutters inclined inboard to dump the drainage water beneath the vehicle.
