Breakaway supports (Pbpbvc)

Design features which allow a device such as a sign, luminaire, or traffic signal support to yield or separate upon impact. The release mechanism may be a slip plane, plastic hinges, fracture elements, or a combination of these. Also, a structural element at or near the bottom of a post or pole which will allow release of the post from its base upon impact while resisting wind loads. (Source: AASHTO Glossary)
