What is a traffic controller?

Traffic controllers are professionals responsible for managing and directing the flow of vehicles and pedestrians to ensure safety and minimize congestion, especially in areas with construction, accidents, or special events. They use signs, signals, and sometimes hand gestures to communicate directions to drivers and pedestrians. Traffic controllers often work outdoors and may be employed by government agencies, construction companies, or private firms. Their role is essential for maintaining order and preventing accidents on roads and highways.
