What is a flagger?

A flagger is a person who directs traffic at construction sites, road work, or other situations where traffic needs to be controlled. They typically use handheld signs, flags, or signals to communicate with drivers and ensure the safety of both the workers and the public. Flaggers must have a good understanding of traffic laws and regulations, as well as the ability to remain calm under pressure and make quick decisions in potentially dangerous situations. Training and certification are often required for flaggers to ensure they have the necessary skills to do their job effectively.
