Who Decides What a Stop Sign Looks Like?

Every day you pass hundreds of traffic signs without a second thought. But behind that red octagon and every speed limit marker lies a surprisingly complex world of optical engineering, federal standards, and a volunteer committee that meets twice a year. This episode breaks down the two questions nobody asks: how much do these signs actually cost, and who designs the visual language we all take for granted? From $15,000 retroreflectometers to the 1968 treaty the U.S. never signed, discover the hidden industry keeping drivers safe at 60 miles per hour.
