A signpost, sign and a coupling mechanism for connecting the sign and signpost. The coupling mechanism incorporates a replaceable shear pin of appropriate material and strength so as to facilitate shearing of the pin in high wind conditions, thereby unlocking the coupling mechanism and allowing the sign to rotate freely about the axis of the signpost. The invention, as described, safely contains a sign attached to a signpost while reducing the possibility of wind forces damaging the sign and/or sign and signpost combination.
