## Summary

**Mandatory side underride guards** would be required on trailers, semitrailers, and single‑unit trucks through a federal performance standard to reduce underride deaths and injuries and improve crash survivability. The bill would also expand research, reporting, and oversight to guide implementation and enforcement. - Families and vulnerable road users: Would aim to cut underride fatalities and injuries by requiring guards that prevent intrusion into occupant survival space at closing speeds up to 40 mph and that block people from passing underneath. - Trucking operators and manufacturers: Would trigger performance‑based rulemaking with a cost‑benefit framework that counts net fuel savings, an 18‑month window to finalize rules, and a 2‑year full compliance deadline after a final rule. - Data, oversight, and enforcement: Would expand the Advisory Committee on Underride Protection, require National Academies and Government Accountability Office studies, strengthen Fatality Analysis Reporting System (FARS) data, and mandate web‑based law enforcement training and 5‑year reviews of standards. *The bill does not itself appropriate new funds and would rely on existing or reallocated agency resources and future appropriations.*
