Yield

The sign on the highway that tells you to yield to oncoming traffic is not as old as you might think. Oklahoma police officer Clinton Riggs came up with the “yield” sign in 1950, which spread from its birthplace in Tulsa to all corners of the US.

He spent more than a decade experimenting with the sign, according to the Tulsa Police Department’s history book. His goal was a sign that would not only control traffic at an intersection but would also attach liability in a collision if one driver failed to yield.
