What is a key reason for obeying traffic signals?

Answer: C — To ensure the safety of all road users

Obeying traffic signals is primarily essential for ensuring the safety of all road users. Traffic signals are designed to regulate the flow of vehicles and pedestrians, preventing accidents by providing clear instructions on when it is safe to proceed or stop. When drivers and pedestrians follow these signals, it reduces the likelihood of collisions and promotes a safer road environment for everyone, including cyclists and other vulnerable road users. The other options highlight important aspects of traffic management—such as maintaining a smooth flow of traffic and avoiding penalties—but the paramount reason is always safety. Traffic signals play a vital role in coordinating movement at intersections and controlling the behavior of all road users, enhancing overall safety on the roads.
