## Abstract

On February 27, 2004, the National Highway Traffic Safety Administration (NHTSA) published a final rule amending the upper interior impact requirements of the Federal motor vehicle safety standard on occupant protection in interior impact to increase the minimum separation distance between tested areas on vertical surfaces of a motor vehicle. The final rule also added targets for pillar-like structures that do not meet the definition of "pillar," i.e., certain door frames and freestanding vertical seat belt mounting structures. The amendments adding the new targets necessitated changes to certain compliance test requirements, including the approach angles specified for certain target locations. The effective date of these amendments was August 25, 2004. This document corrects several typographical errors in the amendatory language contained in the February 27, 2004 final rule.
