What is the primary purpose of traffic signals?

• A. To regulate bicycle lanes
• B. To control the flow of traffic
• C. To enhance street aesthetics
• D. To indicate parking restrictions

Answer: (B)

The primary purpose of traffic signals is to control the flow of traffic. Traffic signals are crucial tools in managing and directing vehicles and pedestrians at intersections, helping to maintain orderly movement and reduce the chances of collisions. By providing clear indications of when to stop, go, or prepare to stop, traffic signals facilitate safer interactions between different road users. This regulation is particularly important in complex traffic situations where multiple roads converge, enabling each type of user to navigate safely through intersections. Without traffic signals, chaos could ensue as vehicles and pedestrians attempt to cross at the same time, leading to increased risks of accidents. Therefore, controlling the flow of traffic is central to the effective operation of road systems, ensuring not only efficiency but also safety for all road users.
