Truck underride guards leave car occupants at risk
Modern semitrailers for the most part do a good job of keeping passenger vehicles from sliding underneath when they crash into the backs of trucks. But the trailers fail to prevent potentially deadly underride in crashes involving only a small portion of the truck's rear, new IIHS tests show.

Passenger vehicles often collide with the fronts and sides of large trucks, but trailers are only required to have guards on the rear.

Underride guards on big rigs often fail in crashes
New crash tests and analysis by IIHS demonstrate that underride guards on tractor-trailers can fail in relatively low-speed crashes — with deadly consequences. The Institute is petitioning the federal government to require stronger underride guards that will remain in place during a crash and to mandate guards for more large trucks and trailers.
Regulators slow to act on upgrade
IIHS has been studying the underride problem for decades, but federal standards have been slow to change.
