What does a red traffic light mean?

Answer: B — Stop

A red traffic light signifies that drivers must come to a complete stop at the intersection. This signal is crucial for maintaining safety on the roads, as it controls the flow of traffic and helps prevent accidents. When a driver encounters a red light, they must wait until the light changes to green before they can proceed. In practical terms, stopping at a red light allows for pedestrians to cross safely and gives priority to vehicles coming from other directions that may have a green light. Understanding the meaning of different traffic signals, especially the red light, is essential for all drivers to navigate intersections safely and follow the laws governing traffic control.
