Traffic cones are typically used outdoors during [[Road#Construction|road work]] or other situations requiring traffic redirection or advance warning of hazards or dangers, or the prevention of traffic. For night time use or low-light situations traffic cones are usually fitted with a retroreflective sleeve to increase visibility. On occasion, traffic cones may also be fitted with flashing lights for the same reason.

In the US, cones are required by the US Federal Highway Administration's ''[[Manual on Uniform Traffic Control Devices]]'' (MUTCD) to be fitted with reflective white bands to increase night-time visibility. Reflective collars, white strips made from white reflective plastic, slip over cones snugly, and tape or adhesive can be used to permanently attach the collars to the cones.

Traffic cones are designed to be highly visible and easily movable. Various sizes are used, commonly ranging from around {{convert|30|cm|in|1|abbr=on}} to a little over {{convert|1|m|in|1|abbr=on}}. Typical traffic cones are fluorescent [[Safety orange|"safety" orange]], but other bright colors including yellow, pink, red, and lime green are also used, with the color depending on context in some countries. The cones usually have a retroreflective strip (commonly known as "flash tape") to increase their visibility at night.

In the United States, they come in such sizes as:
* {{convert|12|in|mm|0|abbr=on}}, {{convert|1.5|lb|kg|abbr=on}} – for indoor/outdoor applications
* {{convert|18|in|mm|0|abbr=on}}, {{convert|3|lb|kg|abbr=on}} – for outdoor applications such as freeway line painting
* {{convert|28|in|mm|0|abbr=on}}, {{convert|7|lb|kg|abbr=on}}, (also called Metro cones for their use in cities) – for non-highway applications such as local streets 
* {{convert|28|in|mm|0|abbr=on}}, {{convert|10|lb|kg|abbr=on}} – for freeway/highway applications (with reflective stripes)
* {{convert|36|in|mm|0|abbr=on}}, {{convert|10|lb|kg|abbr=on}} – for freeway/highway applications (with reflective stripes)

In New Zealand, they are compliant in two sizes for use on all roads; these are:

* 35 in (900mm), up to 16.5&nbsp;lb (7&nbsp;kg) - for all activities on all roads. (with two reflective stripes)
* 17.7 in (450mm), up to 16.5&nbsp;lb (7&nbsp;kg) - for the protection of wet road markings only (with one reflective stripe)
