To thrive as a Union Construction Flagger, you need a solid understanding of traffic control procedures, situational awareness, and the ability to follow safety protocols, typically backed by a high school diploma or equivalent. Certification in flagger training through organizations like the American Traffic Safety Services Association (ATSSA), as well as familiarity with two-way radios, reflective safety gear, and signage, are often required. Strong communication skills, alertness, and the ability to remain calm under pressure help flaggers effectively manage interactions with construction crews and the public. These skills are critical to ensure the safety of workers and motorists, as well as to keep construction projects running smoothly and efficiently.
