What is the maximum non-retroreflective space allowed between orange and white stripes on a cone?

The correct response, which indicates that the maximum non-retroreflective space allowed between orange and white stripes on a cone is 3 inches, aligns with the guidelines established for traffic safety and visibility.

Using cones that have contrasting colors, such as orange and white, is essential for road safety, especially in emergency situations or construction zones. The specification regarding the spacing of the stripes is crucial because it plays a role in maximizing the cone's visibility to drivers. A uniform stripe pattern helps ensure that the cones are easily recognized from a distance, especially in low-light conditions.

Other options present distances that exceed the recommended maximum, which could diminish the effectiveness of the cones in signaling or alerting drivers. Stripes that are spaced further apart may not provide adequate visibility, potentially leading to accidents or confusion in areas where cones are deployed. Therefore, adhering to the specified 3 inches is important for maintaining safety standards and ensuring that emergency or construction zones are appropriately marked.
