Abstract: The present invention discloses an improved spray suppression device for vehicles. One embodiment of the present invention comprises a front panel having generally opposed first and second main surfaces and being configured to have a plurality of first through openings laterally and longitudinally spaced apart from each other, each forming a flow path through the front panel and a plurality of protrusions each having a cap and at least one post, connected to said front panel and positioned to project from the first main surface for substantially facing their leading wheel of the vehicle. Each cap is positioned substantially above at least one said first opening in said front panel and forming a second opening between the first main surface and the cap. The present invention provides a mud flap which allows air to pass through its opening without clogging with mud, rocks, and road debris.
