Builder of Compliant Truck Side Guards

“As part of U.S. DOT’s duty to disseminate research results through the technology transfer process, we engage stakeholders to increase their awareness of technologies that can potentially improve the safety of pedestrians, bicyclists, and others who share the road with large trucks in urban areas. Truck Side Guards for vulnerable road users are devices intended to sweep aside pedestrians and bicyclists in side-impact crashes, instead of being swept underneath the vehicle. Side Guards are one of a number of truck safety features that can help save lives, particularly in urban areas. Today, these devices are required in 47 countries. Over the last five years, a growing number of U.S. cities and commercial insurers have also begun requiring or encouraging their use.”
