What action should you take when approaching a stop sign?

Answer: C — Come to a complete stop

When approaching a stop sign, the proper action is to come to a complete stop. This requirement is dictated by traffic laws and is crucial for ensuring the safety of all road users. A full stop allows the driver to observe the intersection carefully for any other vehicles, pedestrians, or cyclists that may be present. It provides an opportunity to check for oncoming traffic from other directions, ensuring that the driver can safely proceed after assessing the situation. Coming to a complete stop supports the goal of minimizing accidents at intersections, where most collisions occur. It is also essential for compliance with traffic laws, as failing to stop could result in penalties or fines. This action is not just about seeing if it is safe to go; it is about ensuring that all conditions have been evaluated before making a decision to proceed.
