What is a fundamental rule when approaching a stop sign?

When approaching a stop sign, the fundamental rule is to come to a complete stop. This requirement is designed to ensure the safety of all road users, including pedestrians and other vehicles. A complete stop allows the driver to assess the situation fully, checking for any traffic or pedestrians that may be present before proceeding. It helps minimize the risk of collisions at intersections, as failing to stop can lead to dangerous situations.

Options suggesting to slow down but not stop do not fulfill the safety measures that stop signs are intended to enforce. Similarly, yielding only to oncoming traffic, or stopping based on the presence of other vehicles, could lead to misunderstandings about priority at an intersection, potentially resulting in accidents. Always coming to a complete stop ensures that drivers follow traffic laws and stay vigilant.
