They were the first toy franchise ever built from a PSA campaign. The Crash Dummies started as a popular Public Service Advertising Campaign in the 1980’s about the safety of wearing seat belts. Then in the early 90s, a line of action figures (even an accompanying video game) were released.
There was something very comical about these two which made me hope they wouldn’t wear their seat belts and crash into brick walls. I had a few plush dolls myself of the Dummies. I would also get them confused often when hearing about the band Crash Test Dummies. Remember their one song?
The Incredible Crash Dummies seemed to fade out by the mid 90s, but made a comeback in the early 2000s when they became part of the Hot Wheels series by Mattel. The toys are still produced today.
I wrote about them a couple weeks ago:
