The Insurance Institute for Highway Safety (IIHS) concluded at an all-day conference that deadly truck underride crashes could be prevented when passenger vehicles crash into a tractor-trailer truck or straight struck from behind.
In underride crashes, a passenger car crashes into the rear of a tractor-trailer truck and the car ends up jammed under the truck, flattening the passenger compartment and injuring or killing the car’s driver and passengers. Underride crashes are extremely dangerous and many times lead to serious injuries and/or death. Underride incidents also can occur when bicyclists, pedestrians and motorcyclists slide under the truck body.
There are federal rules and regulations that require trailers and some straight trucks to be equipped with rear underride guards, which are steel bars designed to prevent vehicles from sliding under the backs of trucks or trailers. The same rules and regulations imposed by the federal government have been in place since 1953. Now there is movement to amend rules of the National Highway Traffic Safety Administration (NHTSA), which is considering a new standard for the guards to make them stronger.
