The Federal Highway Administration (FHWA), and for that matter the entire highway community, faces immense challenges in reducing the loss of life on U.S. highways. Advances are needed in all four E's of safety: engineering, enforcement, education, and emergency services. On the engineering side, FHWA has researched, marketed, and promoted a number of innovative features and practices. In-service evaluations have proven that many of these measures save lives when used in the proper locations and conditions.
