ABSTRACT:
A post designed for sign post or guide marker use that will yield on impact and that will resume substantially its original configuration after the impact force has been removed. The post is formed as a single member, but with formed longitudinal shear planes to allow it to split along such shear planes upon impact, thereby reducing the tendency of the post to shear transversely. Correspondingly shaped caps and restrainers may be used during placement of the posts and to insure cohesiveness after shearing has occurred.
