Since the implementation of the 55-mph speed limit in 1973 and 1974, the impact of the reduced limit on highway safety has been the subject of considerable discussion. The assessment of the speed limit is complex because of the multitude of factors that potentially affect the situation. A number of these factors are presented and discussed. Pertinent previous studies as well as the current status of the speed limit are reviewed. Despite the work that has been accomplished, there are a number of questions regarding the safety benefits of the limit that remain unresolved. From a safety viewpoint, there is a need for further examination of the costs and benefits of the 55-mph speed limit.
