A legs apron for a motor vehicle includes a middle portion having a longitudinal axis; a first side portion and a second side portion, which extend laterally on opposite sides. The side portions define a first and a second folding portion, which extend according in a prevalent direction substantially parallel to the longitudinal axis. The legs apron has an operating configuration in which the side portions are folded along the folding portions to extend over a respective side transversely with respect to the middle portion. The apron has protection against impacts to protect the lower limbs of the driver. First and second protective bar couple to the first and second side portions. The protective bars each extend parallel or substantially parallel to the longitudinal axis. The protective bars are proximal to the first and second folding portions, to protect at least the femoral portions of the driver's legs.
