What is the primary purpose of traffic signals?

• A. To confuse drivers
• B. To direct traffic and enhance safety
• C. To increase travel time
• D. To allow pedestrians to cross without waiting

Answer: (B)

The primary purpose of traffic signals is to direct traffic and enhance safety. Traffic signals are installed at intersections and pedestrian crossings to regulate the flow of vehicles and pedestrians, creating a safer environment for everyone on the road. By using a standardized system of lights (red, yellow, and green), signals communicate when vehicles must stop, yield, or proceed, thereby preventing accidents and reducing the likelihood of collisions at busy intersections. Traffic signals also help manage traffic congestion by controlling the movement of vehicles in a systematic manner, which can lead to more efficient travel times overall. Their design facilitates the safe crossing of pedestrians as well, ensuring that all road users can share the roadway safely. While their use indirectly contributes to an organized traffic flow and can aid pedestrians, the main focus remains on traffic direction and safety enhancement.
