The present device is directed to a new and improved barrier gate assembly which comprises an automatic vehicle gate operating mechanism and a barrier arm assembly. The barrier arm assembly, attached to the automatic vehicle gate operating mechanism, comprises of a bracket assembly with a hinge assembly attached thereto. The hinge assembly, having a pivot axis transverse to the bracket assembly, pivotally joins the bracket assembly to a plate assembly permitting pivotal movement of the plate assembly away from the bracket assembly. The plate assembly is fixedly attached to the hinge assembly for securing and holding a barrier arm. The barrier arm longitudinally extends from the plate assembly. A magnet-type device is provided on the bracket assembly in alignment with the plate assembly to hold both the plate assembly and the barrier arm in place next to the bracket assembly while preventing pivotal movement of the hinge assembly and thereby the extended barrier arm. Additionally, the hinge assembly is mounted at a transverse angular pivot axis such that whenever the barrier arm is impacted by a vehicle, the barrier arm retracts to it's normal operating position by the force of gravity acting on it. A method for use of the new and improved barrier gate assembly is also disclosed.
