When you see a stop sign, what must you do?

Answer: C — Come to a complete stop

When you encounter a stop sign, the law requires you to come to a complete stop before the intersection. This is crucial for ensuring the safety of all road users, including pedestrians and other vehicles. A complete stop means that your vehicle must come to a full halt at the designated stopping point, which is typically at the white stop line, crosswalk, or before entering the intersection if no line is present. This action allows you to assess any oncoming traffic or pedestrians and make safe decisions before proceeding into the intersection. Failing to come to a complete stop can lead to accidents and is also considered a traffic violation, which can result in fines or other penalties. Options that suggest proceeding without stopping or only slowing down do not comply with traffic laws and may compromise safety. Similarly, stopping only if there's traffic overlooks the necessity of stopping for pedestrians or other vehicles that may not be immediately visible. Therefore, coming to a complete stop is the law and an essential practice for safe driving.
