The Ohio State Police made a movie called “Signal Seven” that was used for driver’s education when I went to High School in Pennsylvania. Gruesome photos designed to scare us into driving safely. Mostly worked. I guess they have another entry.
I remember that one from my drivers ed class in high school.

They sure couldn’t show this now.
