What is the minimum reflective rail height for a Type II MUTCD barricade?

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

Answer: (B)

For a Type II barricade as defined by the Manual on Uniform Traffic Control Devices (MUTCD), the minimum height for the reflective rail is set at 36 inches. This specification is designed to ensure visibility and safety, allowing the barricade to be easily identifiable by both drivers and pedestrians in various lighting and weather conditions. Having the reflective rail at this height maximizes the ability to catch the attention of motorists, especially at night or during adverse weather when visibility may be compromised. The height is determined through research and data that assess how drivers perceive obstacle warnings and the effectiveness of reflective materials in ensuring safety on roadways. Height standards for barricades are critical in maintaining uniformity across different jurisdictions, ensuring that all drivers receive consistent warnings regardless of where they encounter the barricade. This particular height enhances safety by making it clear that a hazard is present, facilitating better decision-making by drivers.
