How wide should the additional white band located approximately 2 inches below the top band on traffic cones be?

The correct answer is that the additional white band on traffic cones should be 4 inches wide. The width of this band is standardized to enhance visibility and ensure consistent recognition of traffic cones in various conditions. The 4-inch width creates a distinct contrast against the orange background of the cone, which aids in drawing attention to the cones from a distance, thereby improving safety for both motorists and emergency responders.

This specific size helps meet guidelines set by traffic safety organizations, emphasizing the importance of uniformity in traffic control devices. Cones that have features like the extra white band are designed to be easily noticeable at night and during adverse weather conditions, further highlighting their role in effective traffic incident management.
