Abstract: A portable sign mountable upon the roof of a vehicle. The portable sign is in the form of a hollow body having three side walls, a top wall and a bottom wall interconnected in a triangular form. The forwardmost edge of the interconnected side walls is positionable towards the front end of the vehicle for reduced wind resistance. Suction cups are mounted on the bottom wall of the body and in conjunction with strap members also mounted on the bottom wall of the body and connectable to the vehicle to provide for secure and removable attachment of the sign body on the roof of the vehicle. Detachable cover members carrying printed indicia are attachable on the side walls of the body to change the printed indicia on the sign. An illumination source is mounted within the body for illuminating the printed indicia formed on the side walls of the body.
