SUMMARY:

This document responds to six petitions for rulemaking to amend the Federal motor vehicle safety standards on platform lift systems for motor vehicles. The purpose of these standards is to prevent injuries and fatalities during lift operation. Pursuant to the agency's partial grant of the petitions, NHTSA proposes to amend the platform lift standards to revise the lighting requirements for lift controls; the location, performance requirements, and test specifications for threshold warning signals; the specifications for the wheelchair test device; the wheelchair retention device and inner roll stop tests; and the lighting requirements for public use lifts.

In addition, NHTSA denies a request to amend the wheelchair test device specifications to include anti-tipping devices and proposes several technical changes designed to further clarify these standards. Finally, this notice discusses a November 3, 2005, interpretation clarifying specific components of the threshold warning signal test specified in one of the standards.
