For a Type III MUTCD barricade, what is the minimum reflective rail height?

The minimum reflective rail height for a Type III MUTCD (Manual on Uniform Traffic Control Devices) barricade is indeed 5 feet. This height is established to ensure optimal visibility for both vehicle drivers and pedestrians, helping to reduce accidents and increase awareness of roadwork or hazards. A height of 5 feet allows the reflective rail to be seen from a considerable distance, especially by larger vehicles, ensuring that the barricade serves its purpose effectively in various traffic conditions. Proper placement of reflective elements at this height also complies with safety standards outlined in the MUTCD, which are designed to maintain uniformity and safety across different types of road signage and barricades.
