Summary

Highlight any text to annotate
The Stop Underrides Act 2.0 requires the Department of Transportation to establish new federal safety standards for side underride guards on trailers and trucks within 18 months, with manufacturers given 2 years to comply, designed to prevent passenger vehicles from sliding under trucks during crashes at speeds up to 40 mph while protecting motorcyclists and cyclists. The bill also directs the National Highway Traffic Safety Administration to review crash fatality data within one year to identify underride crashes that may have been incorrectly reported by law enforcement and to create free web-based training for state and local officers within 18 months to improve how they identify and document these crashes. Together, these provisions aim to reduce deaths and injuries from underride accidents through both better physical protections on trucks and more accurate reporting of when these preventable crashes occur.
