Which traffic control device is frequently used in a taper?

Cones are commonly used in taper setups because they are highly visible and can easily be placed in a sequence to guide vehicles smoothly from one point to another. A taper is a gradual transition where traffic merges or diverges, typically in work zones, and cones effectively help direct traffic while ensuring safety for both drivers and workers.

They are lightweight, portable, and can be quickly arranged or removed as work conditions change. Their bright colors enhance visibility, especially in low-light conditions. Cones also have a lower profile compared to barriers, making them less obtrusive while still serving the crucial purpose of guiding drivers. This property makes them ideal for adjustments in taper configurations where precise spacing and alignment are necessary for safe traffic flow.
