What flag may be required for a construction contractor vehicle operating in restricted areas?

The orange and white checkered flag is used to indicate a construction contractor vehicle operating in restricted areas. This specific flag serves as a vital safety measure, alerting personnel and other vehicles to the presence of construction activities. The bright colors enhance visibility, making it easier for individuals on foot and in vehicles to recognize that a construction area is present, thereby promoting caution and safety. The checkered pattern further aids in visibility, allowing for quick identification even at a distance or in varying lighting conditions. Proper use of this flag is crucial for maintaining safety protocols and ensuring that all individuals within the restricted area are aware of potential hazards associated with construction work.
