If the traffic light is green, what must the driver do?

When a traffic light is green, the driver is generally permitted to proceed through the intersection. However, it is crucial to pay attention to the traffic flow, pedestrians, and potential obstacles. The correct answer emphasizes the responsibility of the driver to ensure the safety of pedestrians.

In many jurisdictions, even when the light is green, drivers must yield to pedestrians who are in, or about to enter, the crosswalk. This prioritizes pedestrian safety and helps prevent accidents. The phrase "wait and permit the pedestrians to cross" underscores the importance of being vigilant and considerate to those who may have the right of way.

The other options highlight misconceptions about driving behavior at a green light. While it may seem clear to proceed without waiting, it is essential to check for pedestrian presence before moving forward. Speeding up to clear the intersection can create dangerous situations if pedestrians are crossing. Finally, continuing only if no vehicles obstruct does not fully address pedestrian considerations, which are critical in maintaining safety at intersections. Thus, the emphasis on waiting for pedestrians when the light is green reflects safe driving practices.
