Stop Underrides Act 2.0
Senate Committee Reviews Stop Underrides Act 2.0 to Shield Cars, Cyclists From Deadly Truck Crashes
Legislative Progress
Key Points
- This bill requires the Department of Transportation to create new safety rules for large trucks and trailers. The main goal is to require 'side underride guards,' which are metal barriers that prevent smaller cars, motorcycles, and bicycles from sliding underneath the side of a truck during a collision.
- The new guards must be strong enough to stop a passenger car traveling at 40 miles per hour from going under the truck. This is designed to keep the 'survival space' of the car intact, giving the people inside a much better chance of surviving a crash that would otherwise be fatal.
- Beyond just cars, the policy aims to protect 'vulnerable road users' like people walking or riding bikes. The guards would act as a shield to keep these individuals from being pulled under the heavy wheels of a moving truck or trailer.
- If passed, the Department of Transportation would have 18 months to finish the new rules, and truck manufacturers would have two years after that to make sure all new vehicles are equipped with the guards. The bill also calls for better training for police to help them identify and report these specific types of accidents.
- The bill also sets up a public website to share research and tell the stories of people who have been hurt or killed in these crashes. It also brings back a special committee that includes safety experts and the families of crash victims to help guide future safety decisions.
Impact Analysis
Personal Impact
Life & Work
Small trucking companies and owner-operators would face new costs to equip new trailers, semitrailers, and single unit trucks with side underride guards. While the requirement only applies to newly manufactured vehicles, it would raise the purchase price of new equipment, adding financial pressure to small fleet operators who already face tight margins in the freight industry.
