What is the primary purpose of traffic signals?

• A. To confuse drivers
• B. To control the flow of traffic
• C. To signal upcoming construction zones
• D. To alert drivers of parking availability

Answer: (B)

The primary purpose of traffic signals is to control the flow of traffic. Traffic signals serve to ensure safe and orderly movement of vehicles and pedestrians at intersections and in other traffic areas. By providing clear indications of when to stop, proceed, or yield, these signals help prevent accidents and maintain a smooth flow on the road. This is crucial, especially in busy urban environments where multiple vehicles and pedestrians interact simultaneously. The efficiency of transportation systems greatly relies on effective traffic signal management. When traffic signals function correctly, they minimize congestion, increase safety for all road users, and contribute to overall traffic efficiency. The other choices reflect scenarios that may occur in driving but do not capture the fundamental role that traffic signals play in regulating traffic and ensuring safe road navigation.
