A traffic gate apparatus comprises an upstanding pedestal. A first elongate arm is also provided having a proximal end and a distal end, with the proximal end of the first elongate arm being pivotally connected to the pedestal at a first pivot axis. A second elongate arm has a proximal end and a distal end, with the proximal end of the lower elongate arm being pivotally connected to the pedestal at a second pivot axis. The second pivot axis is below the first pivot axis such that the first and second elongate arms are movable between a lowered position, in which the first and second elongate arms are generally horizontal and parallel with the first elongate arm being above said second elongate arm, and a raised position. The first and second elongate arms each have an adjustment mechanism such that a length thereof can be varied.
