Additional Facts and Other Interesting Details

Charles P. Rudebaker invented the traffic cone in 1914. The original version was made out of concrete.

It aims to warn drivers in advance about potential dangers and hazards. Aside from these functions, it can also be seen in locations where children are playing.

To enhance its visibility, a retroreflective sleeve is attached to it for low-light situations and for use at night. It commonly comes in bright colors such as red, pink and yellow. At the same time, blue, green and orange are also used to make it more visible.

Aside from the usual outdoor uses, it can also be used indoors, specifically for marking off areas. It can warn people about different kinds of dangerous situations like a slippery floor. Disposable traffic cones are also available, which are made from durable biodegradable paper.
