Summary

AI-generated summary, report an error

This bill would require the U.S. Secretary of Transportation to finalize rules within 18 months requiring side underride guards on new trailers, semitrailers, and single unit trucks. The guards would have to stop a passenger vehicle's cabin from being crushed in side crashes at up to 40 miles per hour, keep pedestrians and cyclists from passing underneath, and support fuel efficiency. Trucks would have to fully comply within 2 years after the rules are final. The bill would also reconvene and expand an underride advisory committee, create a public website of underride research, order studies by the National Academies and the Government Accountability Office, and require a review of crash data and free online training for police on identifying underride crashes.
