What is the function of traffic signals?

Traffic signals are essential components of road safety and traffic management. Their primary function is to manage the flow of traffic effectively to ensure the safety of all road users, including drivers, pedestrians, and cyclists. By providing clear and standardized instructions—such as when to stop, go, or yield—traffic signals help prevent collisions and reduce the likelihood of accidents at intersections and other critical areas.

The presence of traffic signals allows for organized movements in various directions, ensuring that conflicting traffic does not enter the intersection simultaneously. This organization is particularly important in busy urban environments where the volume of vehicles and pedestrians can be high. By regulating traffic flow, signals help maintain order on the roads and facilitate smoother transit, contributing to overall road safety.

In contrast, options that suggest confusion, limitation of vehicles, or indication of weather conditions do not accurately reflect the primary purpose of traffic signals. They are designed to enhance clarity and safety rather than complicate driving or address external factors like weather.
