Traffic cones were invented by Charles D. Scanlon, an American who, while working as a painter for the Street Painting Department of the City of Los Angeles, was unimpressed with the traditional wooden tripods and barriers used to mark roads which were damaged or undergoing repainting. Scanlon regarded these wooden structures as easily broken, hard to see, and a hazard to passing traffic.[4] Scanlon's rubber cone was designed to return to an upright position when struck by a glancing blow. The patent for his invention was granted in 1943.
