What should you do at a stop sign?

Answer: B — Come to a complete stop and yield to any cross traffic or pedestrians

When approaching a stop sign, the correct action is to come to a complete stop and yield to any cross traffic or pedestrians. This is critical for ensuring the safety of all road users. A complete stop allows the driver to assess the intersection and make sure it is safe to proceed before entering or crossing. Yielding to pedestrians is essential because they have the right of way, and failing to stop can lead to dangerous situations or accidents. By stopping completely, you observe the road conditions and gauge the flow of traffic, ensuring that you can make safe driving decisions. In contrast, simply slowing down and proceeding with caution does not guarantee that you've properly assessed the situation, as it may lead to missing a pedestrian or another vehicle approaching the intersection. Flashing lights and moving forward is not an acceptable behavior at stop signs since it disregards the purpose of the stop. Lastly, stopping only if cars are present undermines the principle of traffic control devices, which is designed to enhance safety for all users regardless of whether or not other vehicles are immediately present.
