Current Minnesota Department of Transportation (Mn/DOT) design practice for many traffic signals utilizes an arrangement of steel guard posts to protect the signal, and in particular the signal head, from short turning vehicles. None of the components had been evaluated for automobile impacts and Mn/DOT was concerned about the performance of these installations. Accordingly, this project determines the performance of the guard post/signal support installation when impacted by a 1800-lb (800-kg) class vehicles. Performance criteria were determined for the modified guard post and two different concepts were evaluated in pendulum and vehicle crash tests. The guard post design using a breakaway steel coupling is recommended for installation with the standard signal support.
