The objective of this study was to evaluate with field tests, a procedure developed for the Federal Highway Administration for determining frequencies at which highway safety hardware needs to be inspected and repaired. The frequencies arrived at were based on the accident history of the safety hardware and the level of service to be provided, which is based on the probability of completing the inspection and repair before a subsequent accident. It was concluded that the procedure was a useful method for highway safety hardware maintenance guidelines. Some problems were noted and suggestions were made to resolve them.
