Traffic cones, also called road cones, safety cones, pylons, or
Witches Hats (now considered objectionable), are cone-shaped
markers, generally made out of rubber, that are placed on roads or
footpaths to temporarily redirect traffic in a safe manner. They
are often used to create merge lanes during road construction
projects or automobile accidents, though heavier, more permanent
markers or signs are used if the diversion is to stay in place for
longer periods of time. Traffic cones are designed to be highly
visible and easily movable. Various sizes are used, commonly
ranging from around 30 cm to a little over 1 m. Traffic cones come
in many different colors, with orange, yellow and red being the
most common colors due to their brightness. They may also have a
reflective strip to further increase their visibility to vehicle
traffic.
