The problem
Daimler Trucks North America LLC (DTNA) is recalling certain 2011-2021 Thomas Built Saf-T Liner HDX school buses. The forward seat barriers may not provide sufficient protection to passengers.

The risk
Occupants may collide with the front seat barriers with more force than intended during a crash, increasing the risk of injury.
