A breakaway design for the modification of timber utility poles that will radically increase the safety of passengers in impacting vehicles has been developed and comprehensively tested. This design is called the Hawkins breakaway system (HBS). The system not only accomplishes the goal of increasing safety but exhibits characteristics of significant advantage to a utility company. A statement of safety philosophy applicable to the evaluation of roadside structures has been prepared. It can be used as the basis for the evaluation of any proposed safety improvement relative to roadside geometry and structures. It was used here to develop compliance tests for breakaway utility poles and to evaluate the results of those tests. Analysis of the literature relative to the cost-effectiveness of breakaway utility poles reveals that there will be a positive societal benefit associated with carefully selected applications.
