According to MUTCD barricade specifications, what is required for minimum height?

The minimum height requirement for barricades, as specified in the Manual on Uniform Traffic Control Devices (MUTCD), is 36 inches. This height ensures that the barricades are visible and effective at enhancing safety for both vehicle operators and pedestrians during construction or maintenance activities. At 36 inches, barricades provide adequate visibility to alert approaching traffic about hazards or obstructions ahead, thereby reducing the risk of accidents. This specification is part of a broader effort to ensure that traffic control devices maintain consistent standards across various jurisdictions, promoting safety and clarity in road usage.
