We share our roads and highways with large commercial trucks on a daily basis. These large commercial trucks have rear guards to protect passenger cars. If you rear-end an eighteen-wheeler, you are protected from going under the back of the truck. Why do large trucks not also have side guards? That’s a question safety advocates have long asked.
Commercial trucks can have a very high ground clearance. I’m sure you’ve been in the lane next to a large eighteen-wheeler. If you are in a small passenger car, you may even look over and think that your entire vehicle could go under the truck. That is the danger. In a side impact, a passenger car can slide under the body of the truck. That causes the truck body to crash through the car windows and into the passengers. A simple collision can become deadly. These under-ride crashes can cause horrible head and upper body injuries, including decapitation. The Insurance Institute for Highway Safety estimated almost 300 car passengers were killed in side-impact collisions with a semi-truck in 2016.
We need to remember — Deadly side impacts are not limited to passenger cars. In urban areas, commercial trucks frequently share our roads with pedestrians and bicyclists. A Department of Transportation study also revealed a substantial number of death in side crashes involving both pedestrians and bicyclists.
