What this bill would do
The "Stop Underrides Act 2.0" aims to reduce deaths and injuries caused by underride crashes involving trucks and trailers. It directs the Secretary of Transportation to finalize regulations for new motor vehicle safety standards, specifically focusing on side underride guards. These standards must ensure that guards prevent intrusion into passenger vehicle space and impede Vulnerable Road Users from sliding underneath vehicles. The bill also mandates the reconvening of the Advisory Committee on Underride Protection. Additionally, it requires various studies from the National Academies and the GAO, as well as a review of fatality reporting systems.
