Abstract: A splash guard to be suspended adjacent a vehicle wheel to reduce splash of liquid and slush comprises a sheet having a splash receiving surface covered with a plurality of spaced apart, discrete, elongated, stiff protuberances that are arranged in a pattern defining downward flow paths along the sheet and that direct liquid and slush thrown from the wheel into the flow paths, from which the liquid and slush can drain from the sheet. The sheet is reinforced by downwardly extending ribs which also impede sideward splashing. The protuberances and ribs are integral with the sheet. The sheet of elastomeric material is reinforced adjacent the splash receiving surface by embedded threads. The ribs are reinforced adjacent their free edges by embedded threads. The reinforcing threads resist excessive convex bending of the sheet. A guard of similar structure can be attached to the underside of a vehicle above the wheel.
