When a vehicle ahead of you stops for a pedestrian, what should you do?

Answer: B — Stop behind the vehicle

When a vehicle ahead of you stops for a pedestrian, the correct response is to stop behind the vehicle. This action is essential to ensure the pedestrian's safety, as they may be crossing the street and may not be visible to you due to the stopped vehicle obstructing your view. Stopping allows both the pedestrian to cross safely and the stopped vehicle to yield its right of way without any further obstructions. Passing the stopped vehicle could endanger the pedestrian, as they may not be aware of your approach. Honking might startle the pedestrian or the driver of the stopped vehicle, creating an unsafe situation. Changing lanes could also put both you and the pedestrian at risk if other vehicles are present or if it is not done safely. Therefore, coming to a complete stop behind the stopped vehicle is the safest and most responsible action to take.
