ABSTRACT:
A self-erecting sign post has a rigid but frangible section along its length at its lower end and a coextensive helical spring circumjacent the rigid section and interconnecting the separated post portions, the assembly being such that the frangible section constitutes a zone of weakness which will break before the remainder of the sign post bends upon impact, the spring being operative to restore the sign post to its erect position until the frangible section can be replaced.
