Traffic signals direct traffic flow from two directions.

• A. True
• B. False
• C. Sometimes they don't
• D. Only at certain times

Answer: (A)

Traffic signals manage which direction can move and when, ensuring opposing traffic at an intersection doesn’t collide. They run in cycles that give one direction (and any turning movements) the green while the other direction is stopped with a red, then switch. This coordinated timing directs traffic flow from two directions so that conflicting movements are separated safely. Even though you might see dedicated turn phases or pedestrians crossing, the essential purpose is to regulate flow for the directions that cross each other. So the statement is true. The idea that signals don’t always direct flow, or only do so at certain times, isn’t accurate—the whole system is built to coordinate movement between opposing directions.
