What should you do when approaching an intersection with a green signal and a pedestrian crosses against the red signal?

When approaching an intersection with a green signal and encountering a pedestrian crossing against a red signal, the most appropriate action would be to stop immediately, prioritizing the safety of the pedestrian. While the green signal indicates that vehicles have the right of way, it is essential to recognize that traffic signals for vehicles and pedestrians operate independently.

In this situation, although the answer provided suggests using a horn to give a warning, the focus should be on ensuring that no harm comes to the pedestrian. Stopping immediately allows the pedestrian the opportunity to complete their crossing safely, even if they are not following the pedestrian signal.

Continuing to drive at the same speed could lead to a dangerous situation where the pedestrian may not have enough time to clear the road, resulting in a potential collision. Similarly, waiting for the pedestrian to finish crossing while still in motion could have the same risky outcome. Therefore, the best course of action is to stop and yield to the pedestrian, ensuring their safety first and adhering to the principle of cautious driving.
