It’s a big fear of many drivers cruising behind big rigs: What if this thing just opened up?

Thankfully, this rarely happens. However, “rarely” doesn’t mean “never,” and now, we have video showing just how bad it can be when that happens.

This big rig truck was making its way around a turn when, for one reason or another, its rear door became unlatched. The door proceeded to hit a car, which is when things went from bad to worse.

If this ever happens to you, you should probably just get out of the car.
