Traffic cones are typically used outdoors during road work, other situations requiring traffic redirection and advance warning the hazards or dangers, or the prevention of traffic. Road cones are also used to mark where children are playing or to block off an area. For night time in low-light situations safety cones are usually fitted with a reflective sleeve to increase visibility.

Collapsible safety cones are designed to be highly visible and easily movable and various sizes are used, commonly ranging from around 30 cm to a little over 1 m. Traffic safety cones come in many different colors, with orange, yellow, and red being the most common colors due to their bright color. Some traffic rubber cones come in green and blue, and may also have a reflective strip to increase their visibility.
