How wide must the top reflective band be on cones that are 28 to 36 inches high?

The top reflective band on cones that are 28 to 36 inches high must be 6 inches wide to conform to safety standards established for traffic control devices. This width ensures that the bands are visible enough for drivers and help in delineating the presence of the cones, especially in low-light conditions or adverse weather. The visibility provided by a 6-inch reflective band significantly enhances the safety of scenes involving traffic incidents, making it easier for approaching vehicles to recognize the presence of the cones from a distance.

A band of this specified width serves a crucial role in maintaining clarity and ensuring that traffic is managed effectively around incidents or work zones. In contrast, bands that are narrower do not provide the same level of visibility and could lead to dangerous situations on the road. In this context, understanding the specific width for cones helps in ensuring compliance with traffic safety regulations, thus enhancing overall incident management practices.
