A vehicle floor tray has a base, upstanding side walls, a forward panel, and an aft wall that define a basin for confining liquid such as water, mud, and slush. An array of spaced apart chevron-shaped treads project upwardly from the base. The chevron-shaped treads are arranged in adjacent rows and the treads in each row are oriented in a direction opposite from the direction of orientation of the treads in adjacent rows. Further, each row of treads is shifted or staggered with respect to adjacent rows by a distance substantially equal to half the length of a tread plus half the distance between adjacent treads in a row. This configuration forms a convolutedly shaped network contiguous channels within which liquid may collect and spread out. The shape of the channel network and the shapes and orientations of the chevron-shaped treads inhibits the mass flow of liquid to the front, back, or sides of the floor tray during acceleration, deceleration, and up or down hill traverses. This, in turn, inhibits puddeling of liquid during off-road operation of a vehicle and the problems attendant thereto.
