Stop Underrides Act 2.0

The Stop Underrides Act 2.0 requires new safety standards for side underride guards on commercial trucks and trailers to prevent passenger vehicles from sliding under them during collisions. The bill mandates that the Secretary of Transportation finalize regulations requiring these guards within 18 months, with full compliance required within two years. The regulations must meet specific performance standards to prevent intrusion into passenger vehicle occupant space during side collisions at speeds up to 40 mph. This law directly affects commercial truck manufacturers, trucking companies, and all road users, particularly vulnerable road users like cyclists and pedestrians who are at higher risk in underride crashes. The bill also establishes a public website for underride crash resources and requires studies to better understand and prevent these crashes.
