They use hand signals, stop/slow paddles, and two-way radios to communicate with workers and drivers.

Familiarity with two-way radios, traffic signage, and high-visibility safety equipment is typically required. Strong communication skills, alertness, reliability, and the ability to stay calm under pressure set standout candidates apart. These skills are crucial to ensure the safety of workers, drivers, and pedestrians while facilitating smooth and efficient traffic flow through construction or event zones.
