ABSTRACT:
A vehicle control gate arrangement pivotable to a position for restricting flow of vehicular traffic where the gate is generally elongate and can include a tubular shell and a core member where the shell is more flexible than the core and contacts the core substantially continuously around the periphery of the core. The core can be terminated toward the distal end of the gate so that the shell extends outwardly from the termination of the core so that vehicles attempting to bypass the end of the gate but failing to do so, strike the flexible end of the gate so the gate is not damaged or knocked down. An arrangement is also provided to include a gate composed of one or more sections connected to an adjacent section or to a pivot by a joint assembly which releases the outermost section in the event the section is struck by a vehicle attempting to or accidently going through the gate.
