What is the correct action when approaching a red traffic signal?

Answer: B — Come to a complete stop

When approaching a red traffic signal, the appropriate action is to come to a complete stop. A red signal indicates that vehicles must halt to allow cross traffic and pedestrians to move safely through the intersection. This rule is essential for maintaining order and safety on the road, as it prevents potential collisions and ensures that all road users can navigate the intersection without danger. While turning left or yielding to pedestrians may be relevant in specific contexts (such as at some intersections where turns on red are allowed after a full stop), the fundamental rule is to always stop at a red light. Continuing through the intersection or proceeding without stopping endangers not only the driver but also other road users, including pedestrians. Therefore, stopping at a red light is a critical part of traffic law that helps promote safe driving practices.
