Disclosed is a pivotable signpost support device. The device includes a signpost support that is vertically aligned with a ground post support, wherein the signpost support is disposed above the ground post support that is affixed to a ground post. The signpost support and the ground post support are secured between first vertical support and a second vertical support. The signpost support is pivotally secured to the first and second vertical supports by means of a pivot bolt having a die spring at an end thereof, so that it can pivot forward and backward relative to the first and second vertical supports. The pivot bolt can tighten the die spring so as to keep the signpost support in an upright position but allowing the signpost support to fall into a collapsed position.
