This type of situation usually equals instant death.
This incredible dash cam footage comes to us from Poland and was taken at a red light. What should have been a quick and boring wait for the light to turn green quickly became a scene of vehicular carnage as a speeding truck takes out four cars. It started when the truck came around a corner and struck a car in the intersection. Immediately after the initial hit the truck fell onto its side and skidded into the car in front of the cammer. The truck then struck the cammer's car before coming to a complete stop.
Despite five cars being involved in the accident no one was killed, although seven people were slightly injured according to the video description.
