Breakaway sign post |
摘要 |
A breakaway sign post assembly (30) is disclosed as including a sign support post (32), an anchoring post (34) and a breakaway collar (100). The breakaway collar (100) includes a sidewall (102) which surrounds the sign support post (32). The sidewall (102) includes at least one substantially vertical line of weakness (120) configured to facilitate a portion of the sidewall (102) to give way. The sidewall (102) retains the sign support post (32) in a manner to define a fulcrum (134) about which the sign support post (32) turns when a vehicle impacts and exerts a lateral force at an impact location, with the fulcrum (134) being positioned below the impact location so that the support post (32) will swing generally away from the vehicle.
