Side Underride Guards

Advance notice of proposed rulemaking (ANPRM).

This ANPRM responds to Section 23011(c) of the November 2021 Infrastructure Investment and Jobs Act (IIJA), commonly referred to as the Bipartisan Infrastructure Law (BIL), which directs the Secretary to conduct research on side underride guards to better understand their overall effectiveness, and assess the feasibility, benefits, costs, and other impacts of installing side underride guards on trailers and semitrailers. The BIL further directs the Secretary to report the findings of the research in a Federal Register notice to seek public comment. In addition, this ANPRM also responds to a petition for rulemaking from Ms. Marianne Karth and the Truck Safety Coalition (TSC).
