## Narrative
Semi was traveling on the highway and transporting a 48,000 pound steel coil. The steel coil was secured with 4 chains. The automatic emergency braking system engaged with nothing in front of the vehicle, causing it to suddenly come to a dead stop in traffic. This caused the steel coil to break free of its bounds, crash through the trailer and into the vehicle cab, trapping the driver.
