What is Traffic cone?
[[File:Cones.jpg|thumb|right|Traffic cones are usually used to divert traffic.]] [[File:Traffic cones london.jpg|thumb|right|Traffic cones used by the Metropolitan [[police]]]] '''Traffic cones''' (also called '''road cones''', '''safety cones''' or '''pylons''') are [[cone]]-shaped markers, usually made from [[plastic]], that are put on roads to temporarily redirect [[car]] [[traffic]] in a safe manner. == Uses == Traffic cones are usually placed around construction sites or roadside accidents. As well, many utility companies such as telephone companies and electric companies place cones on the road when utility workers are working on or near the road. Cones are also used by driving schools to set up tests of turning and parking skills. They have many other uses including bike training, fun and for personal use like reserving parking spaces. On top of traffic redirection, traffic cones are often used in sports as markers to test and train for skills like agility and precision. Traffic cones are often used due to their resilient [[rubber]] construction, and a new one can easily handle being run over multiple times and be reformed by stacking it between other cones. However, a disadvantage to this rubber construction is that older traffic cones tend to become brittle, and easily shattered. Due to their rubber construction, they can easily be dropped off of specialized road striping trucks to mark [[paint]]. == Features == Traffic cones are easily movable and about 60&nbsp;cm (24 [[inch]]es) tall. Traffic cones come in many different colors, with orange, yellow and red being the most common colors. Many types of traffic cones have reflective strips or stripes of reflective paint, so that the cones are easier to see at night. == History == Traffic cones were invented in [[1914]] by Charles P. Rudabaker. The first cones were made of [[concrete]]. In the 2000s, most cones are made of brightly-colored plastic. == Other websites == * [http://www.trafficcone.com The Traffic Cone Preservation Society] * [http://ww
