Traffic Cone Info

Traffic cones are usually used outdoors for road work or other things that require traffic to be diverted.  Sometimes traffic cones have reflective sleeves or reflective collars so that they can be seen during the night.  When traffic cones have retroreflective collars, they meet the MUTCD (Manual on Uniform Traffic Control Devices).

Traffic cones can range from 30 cm to over 1 m.  When it comes to colors, brightness is the most important.  Orange, yellow, pink, and red are the most common because of this.
