What is the minimum height requirement for Type 3 barricades?

Type 3 barricades are designed for high-visibility and safety in work zones, particularly when traffic is present. The minimum height requirement is set at 5 feet to ensure that they are easily seen by drivers from a distance, especially in scenarios where clear sightlines are critical for safe navigation. This height helps to prevent accidents by clearly delineating the work area, making it obvious to both drivers and pedestrians. The increased height compared to lower barricades allows for better visibility above vehicle hoods and other obstructions that may be present on the road. Thus, the 5-foot requirement is essential in promoting safety and compliance in work zones, ensuring that these barricades serve their intended purpose effectively.
