For a nighttime Short Term Stationary Traffic Control Zone setup on a low speed/low volume street, the minimum height of traffic cones used shall be ________?

In a nighttime short-term stationary traffic control zone setup on a low-speed/low-volume street, using traffic cones that are a minimum of 28 inches in height is essential to ensure visibility and effectiveness. Cones of this height are typically designed to be seen clearly under low-light conditions, which is crucial for the safety of both drivers and any workers present in the area.

A height of 28 inches is often specified in guidelines for traffic control devices because it strikes a balance between being tall enough to be easily noticed by drivers while still being manageable for placement and transport. Ensuring that traffic cones reach this height helps to prevent accidents and enhances overall traffic flow by clearly delineating work areas and guiding vehicles appropriately through the setup.

While taller cones may have their own advantages in certain situations, the designation of 28 inches is commonly accepted as the minimum standard for this specific context, ensuring compliance with safety regulations and contributing effectively to nighttime visibility.
