Traffic signals direct traffic flow from two different directions.

• A. True
• B. False
• C. Only pedestrians
• D. Not at all

Answer: (A)

Traffic signals at intersections control the movement of vehicles coming from different directions by designating which direction can proceed and what movements are allowed in each phase. They cycle green and red for each approach so one direction goes while the other waits, and then the roles swap, preventing conflicts between opposing flows and turning movements. Pedestrians are coordinated with these signals, but the main purpose is to regulate vehicle flow from two directions safely. So the statement is true because signals are built to direct traffic coming from two directions, not only pedestrians or nothing.
