This bill proposes to amend Section 30112(b)(10) of title 49, United States Code, which generally prohibits the introduction of noncompliant motor vehicles and equipment into interstate commerce. The amendment specifically creates an exception to this prohibition, allowing manufacturers to introduce certain noncompliant motor vehicle equipment for testing and evaluation purposes. This new allowance extends an existing provision that already permits the introduction of noncompliant motor vehicles for similar testing. By explicitly including "items of motor vehicle equipment," the bill aims to enable the development and assessment of innovative automotive components under controlled conditions before they are required to meet full compliance standards or are made available to the public.
