#semi-trucks

In National Lampoon’s Christmas Vacation, Clark W. Griswold road rages his Ford Taurus station wagon under a logging truck to comedic effect. However, without the benefit of movie magic, the following sequence of that film should have been a joint funeral for the entire family. Crash tests conducted by the Insurance Institute for Highway Safety prove that underride accidents are as devastating as they look, and the IIHS is demanding the implementation of every safety solution available.

While tractor-trailers are legally obligated to affix underride guards to the rear of their vehicles, the same can’t be said for their flanks. Unsurprisingly, there are more passenger fatalities stemming from incidents where a vehicle strikes the side of tractor-trailer than those where it impacts the rear. Since rear underride guards have proven successful in the lab and on the highways, isn’t it time we utilized similar countermeasures for a truck’s haunches?
