What is the minimum height for traffic cones used in work zones?

The minimum height for traffic cones used in work zones is 18 inches. This height is essential for visibility, as it allows the cones to be clearly seen by motorists and helps to effectively direct traffic around a work zone. The 18-inch height strikes a balance between being noticeable without being overly cumbersome, ensuring that they can be easily deployed and will withstand various environmental conditions such as wind.

Using cones that are at least this height helps to maintain safety by providing a clear visual cue to drivers about the presence of work zones, thus reducing the likelihood of accidents or confusion. It also aligns with guidelines established by agencies responsible for road safety and construction zone management, ensuring compliance with best practices in traffic control.
