They are lightweight, easily transportable and highly visible, making them a cheap, efficient and effective method of alerting drivers to new traffics and directions. They are often used during roadwork and emergency traffic direction or to restrict parking zones. Traffic cones are generally available in orange color for increased visibility, but they are also available in various bright colours.
