Speeding is a significant threat to public safety and warrants priority attention. The Department of Transportation's policy on highway speeds is to provide guidance to State and local governments to set speed limits that maximize the efficient and rapid transportation of people and goods while eliminating the unnecessary risk of crashes due to unsafe speeds. This policy promotes the concept that Federal, State, and local governments should have balanced programs that use the most cost-effective strategies for decreasing crash risks from speeding. These strategies include: (1) ensuring that posted speed limits are reasonable and appropriate for conditions; (2) providing public information and education on the risks associated with speeding; (3) understanding who speeds, where, when, and why; (4) using a variety of techniques and technologies beyond enforcement for speed management; and (5) targeting enforcement where speeding presents the most serious hazard and accompanying it with public information and education.
