HNTSA finalizes under-ride rule.

This article reports that the National Highway Traffic Safety Administration (NHTSA) has issued a final rule in the Federal Register that clarifies standards for under-ride guards for trailers and semi-trailers that were established in 1996. The rule is effective immediately. The final rule was enacted to resolve the issue for vehicles that can't practically have under-ride guards installed due to having certain equipment mounted on the rear and underneath a trailer or semi-trailer. Such vehicles are designated as "special purpose vehicles" by NHTSA.
