## Abstract

In a final rule published in August 2006, NHTSA amended its safety standard on occupant crash protection to establish the same 56 km/h (35 mph) maximum speed for frontal barrier crash tests using belted 5th percentile adult female test dummies as it had previously adopted for tests using belted 50th percentile adult male dummies. The agency adopted the amendment to help improve crash protection for small statured occupants. In this document, in response to petitions for reconsideration of that rule, we are adjusting the phase-in requirements to permit manufacturers to earn advance credits for vehicles that are certified in compliance with the new higher speed requirement one year in advance of the regulatory requirements, i.e., beginning on September 1, 2008. We are also making technical corrections regarding special phase-in provisions for small volume manufacturers included in the August 2006 rule, as well as in several other regulations.
