VIDEO - Crashing Into the Rear of a Commercial Trailer
I've always wondered how well the underride protection at the back of heavy commercial trailers would work, but I was never called on to investigate a collision like this. The Insurance Institute for Highway Safety (IIHS) has produced a video that shows these underride prevention structures provide poor protection when built to US standards and only slightly better protection when built to Canadian standards.

This video was produced for Responsible Young Drivers, a group from Belguim. The group promotes road safety and draws the attention to young drivers asking them to demonstrate responsible driving. It's network of 600 young volunteers in organize more than 250 activities each year in Belgium.
