A pair of cut-to-fit universal vehicle floor mats includes a driver's side floor mat and a passenger's side floor mat, each with a plurality of peripheral cells separated from each other and from a central area of the mat body by indented trim lines. The passenger's side mat is not a mirror image of the driver's side mat but differs therefrom in the shape of its exterior margin and the number, length, positioning and shape of the trim lines. The driver's side mat has cells which can be selectively trimmed away to accommodate a gas pedal, deadpedal, transmission tunnel indentation and fuel filler door/trunk release levers. The passenger's side mat has arcuate trim lines and cells adapted to fit a transmission tunnel bulge and a right front wheel well which often delimit the passenger's side foot well.
