Is it advisable to wave a flag as high as possible while directing traffic?

Waving a flag as high as possible while directing traffic is not advisable because it can reduce the flag’s visibility to drivers. The primary goal of a flagger is to ensure that they are seen clearly and that their signals are effectively communicated. When a flag is held too high, especially in relation to the driver's line of sight, it may lead to confusion, as drivers may not be able to interpret the flagger's signals properly.

Furthermore, the proper flagging technique emphasizes maintaining a position where the flag is at a height that is easily visible to approaching motorists, ensuring that traffic can be directed safely and efficiently. Adhering to best practices in traffic control helps to prevent accidents and enhances safety for both workers and drivers in the work zone. Therefore, keeping the flag within a reasonable height, usually around waist to shoulder level, is crucial for effective communication and safety.
