These traffic cones were a substitute for red lantern paraffin burners being used during construction on the high ways and Bypass , India believes that he constructed the first experimental plastic traffic cones, which replaced pyramid-shaped wooden ones previously used.
Cones are also frequently used in indoor public spaces to mark off areas which are closed to pedestrians, such as a restroom being out of order, or to denote a dangerous condition, such as a slippery floor. They can be used on school playgrounds to limit areas of a playing field, and on ice rinks to define class, private party, or private lesson areas. Some of the cones used for this purpose are miniature, as small as 75 cm tall, and some are disposable full-size cones made of biodegradable paper.
The traffic signs on National Highways and other roads must conform strictly to the configuration, colour scheme and location as prescribed in IRC:67-2001, which is also based on the UN Convention on Road Signs and Signals, Vienna November 1968 of which India is one of the signatories.
