Abstract: A toll pass display assembly comprises a mounting plate, a suction cup and coupler. The mounting plate is fabricated of a relatively hard material and has a generally rectangular configuration. It has a front surface and a rear surface. There is a long top edge with a parallel bottom edge and two parallel side edges there between. There is next provided a suction cup which is fabricated of a flexible elastomeric material. The suction cup has an internal generally spherical concave surface and an external generally spherical convex surface with a round circumferential edge there between. Lastly, there is provided a suction cup coupler. The coupler is fabricated of the same type of flexible elastomeric material as the suction cup and formed integrally therewith. The coupler has a front section coupled to the mounting plate. A pair of hook and loop fastener strips are coupled to the front surface of the mounting plate.
