Bill Summary · S 3775

Legislative bill overview

The Stop Underrides Act 2.0 establishes federal safety standards requiring underride guards on large trucks and trailers to prevent smaller vehicles from sliding beneath them during collisions. The bill mandates that these protective devices meet specific performance requirements and would apply to newly manufactured commercial vehicles and potentially retrofit existing ones.

Why is this important

Underride accidents—where passenger vehicles become trapped beneath trucks—result in severe injuries and deaths that are often preventable through proper guard design. The National Highway Traffic Safety Administration has documented hundreds of fatalities annually from underride crashes, making this a significant public safety issue with clear engineering solutions already available.

Potential points of contention

  • Implementation costs: Trucking industry concerns about expense of installing/retrofitting underride guards and whether those costs get passed to consumers
  • Retrofit requirements scope: Disagreement over whether existing trucks should be required to add guards (more protective but more expensive) versus only requiring them on new vehicles (less disruptive but less comprehensive)
  • Guard design standards: Technical debate over what constitutes adequate protection without creating new safety issues or unintended consequences for emergency response or vehicle handling
