Abstract

This report describes 22 full-scale crash tests conducted to evaluate the impact performance of widely used support systems for small roadside signs. Promising new support systems were also evaluated. All systems were of the single post type, with one exception. One system had a vertical post and a back brace. Also summarised are the results of recent crash tests sponsored by industry on small sign support systems. Test results and test articles were evaluated in terms of current AASHTO performance specifications and FHWA guidelines.
