A foldable vehicle floor mat can be used as a ballistic shield when unfolded and attached to a vehicle door. The mat comprises a weather protective layer and an impact-resistant layer. When completely unfolded, the mat covers the length and height of the vehicle door, for which it was designed. The mat is provided with hanging hooks attached to the upper side of the mat, whereby the mat can be hung upon the vehicle door, and a ballast weight attached to the bottom side of the mat, whereby draping the mat across the door is facilitated, and magnetic strips can be provided along the perimeter of the unfolded mat.
