What is the maximum height of reflective rail stripes on a MUTCD directional indicator?

• A. 12 inches
• B. 24 inches
• C. 36 inches
• D. 48 inches

Answer: (C)

The maximum height of reflective rail stripes on a Manual on Uniform Traffic Control Devices (MUTCD) directional indicator is specified to be 36 inches. This height is determined to optimize visibility and effectiveness in guiding vehicles and pedestrians, while also adhering to safety standards. The reflective material enhances visibility, especially in low light conditions, ensuring that the directional indicators are easily seen from a distance. Maintaining a standardized maximum height is crucial for consistency across different locations, allowing drivers to quickly recognize and interpret the signage as they approach. It ensures that the indicators can be seen over various environmental conditions, such as the presence of obstructions or varying heights of vehicles. Thus, adherence to this guideline helps improve overall traffic flow and safety.
