Abstract
A support post or coupling for a sign post assembly having an integrated breakaway system. The post or coupling has a selected predetermined shape and is adapted for carrying an associated structure. The post or coupling includes an integral weakened region providing an area of structural weakness for allowing the support post to shear upon impact by a vehicle traveling at a minimum speed and impacting the support post from a desired impact angle. The integral weakened region is formed by reducing the cross-sectional area of a portion of the support post such that it is slightly less than the cross-sectional area of the remainder of the support post. The integral weakened region may be formed by swaging the support post, by scoring a groove within the support post, or by creating a series of dimples or perforations within the support post.
