What does a traffic officer's signal do?

A traffic officer's signal plays a critical role in managing road safety and efficiency. When an officer is directing traffic, their signals take precedence over any traffic control devices such as stop signs, traffic lights, or yield signs. This is essential in situations where the flow of traffic may need to be adjusted due to an accident, construction, or other unusual conditions on the road. The officer’s signal is designed to ensure that vehicles and pedestrians respond to real-time conditions, prioritizing immediate safety and helping to prevent accidents.

While signals from officers can also assist in directing pedestrians, indicating hazards, and clarifying right-of-way rules, these functions are secondary to the overriding authority of an officer's signal in traffic situations. Their commands are essential for maintaining order and safety on the roads, especially in chaotic situations where regular traffic signals may not adequately address the needs of the moment.
