What width should the white retroreflectorization band on a cone be if the cone is 28-36 inches in height?

The width of the white retroreflectorization band on a cone that is 28-36 inches in height should be 6 inches. This specification is essential for ensuring that the cone is highly visible, especially in low-light conditions or during nighttime. The retroreflective material enables light from vehicle headlights to bounce back towards the driver, significantly enhancing the visibility of the traffic control device.

By standardizing the width to 6 inches for cones within this height range, it ensures consistency and effective visibility across various environments and conditions. This measurement aligns with established guidelines that promote safety by making sure that these warning devices are easily recognized by drivers, thereby reducing the risk of accidents in areas where cones are deployed for traffic control or incident management.
