For nighttime Short Term Stationary Temporary Traffic Control Zones on low speed streets, what is the minimum height of traffic cones?

• A. 24 inches
• B. 28 inches
• C. 30 inches
• D. 32 inches

Answer: (B)

The minimum height of traffic cones for nighttime short-term stationary temporary traffic control zones on low-speed streets is established to ensure visibility and effectiveness in directing traffic safely. Traffic cones serve as a visual barrier to alert drivers about potential hazards or changes in traffic patterns. A height of 28 inches strikes a balance between visibility to drivers and the practicality of being used in various conditions, including night operations. This height is generally accepted because it allows cones to be seen from a sufficient distance, helping to reduce accidents in areas where drivers may not expect temporary traffic control measures. A height of 28 inches is also compliant with industry standards that dictate the dimensions required for effective traffic control, particularly at night when visibility is often compromised. Therefore, using 28-inch cones ensures they are large enough to be effective without being cumbersome or overly intrusive in roadways.
