Procedures are presented for conducting vehicle crash tests and in-service evaluation of roadside appurtenances. These appurtenances are (1) longitudinal barriers such as bridge rails, guardrails, median barriers, transitions, and terminals; (2) crash cushions; and (3) breakaway or yielding supports for sign and luminaries. Test vehicles include minicompact, compact, and standard size passenger sedans, intercity and utility buses, and tractor-trailer cargo trucks. Impact conditions of speed, approach angle, and initial point of contact are delineated along with data acquisition requirements and test results evaluation criteria. Procedures for performing inservice evaluation, a final stage of development of new or extensively modified appurtenances, are presented. Objective of in-service evaluation is to appraise actual performance of an appurtenance during a broad range of collision, environmental, operational, and maintenance situations for typical site and traffic conditions.
