A vehicle floor tray is molded from a sheet of thermoplastic polymeric material of uniform thickness. The tray has a deep three-dimensional shape formed by a floor and at least first and second upstanding sidewalls. A reservoir portion of the floor has a general surface depressed below a general portion of the floor. Channels formed in the general portion of the floor run into the reservoir, in which is formed a plurality of baffles provided for retarding lateral movement of collected runoff and also acting as treads for the occupant's feet.
