ABSTRACT:
A hinged vehicle gate arm is mounted for automatic traffic control on a gate operating mechanism. The arm includes a first section mounted to the gate operating mechanism and a second section attached to the first section by a hinge assembly for pivotal deflection of the second section upwardly of the first section. A resilient roller is mounted for longitudinal rotation below and substantially the length of the second section. The resilient roller and hinged section section limit damage to a vehicle contacted by the arm lowered by the gate operating device.
