What is the primary purpose of proper traffic control devices at work sites?

The primary purpose of proper traffic control devices at work sites is to mitigate hazards. Traffic control devices are designed to improve safety by clearly signaling to both workers and the public the presence of construction or maintenance activities, as well as directing traffic and pedestrian movements in a way that minimizes risks associated with work site conditions. They serve to alert drivers and pedestrians to potential dangers and promote safer behavior in areas where normal traffic patterns are disrupted.

While directing employee movements, informing the public, and increasing overall safety are all important aspects of traffic control, they serve a secondary role to the essential function of mitigating hazards. The use of appropriate devices such as signage, barriers, and cones helps reduce the likelihood of accidents and ensures that all individuals in the vicinity are aware of the potential dangers present at a work site. This leads to a safer environment for both workers and the passing public.
