What is the correct action to take when approaching a stop sign?

When approaching a stop sign, the correct action is to come to a complete stop and yield to any cross traffic. This requirement ensures that drivers are fully aware of their surroundings and can safely assess any other vehicles or pedestrians that may be present at the intersection. A complete stop allows drivers a moment to check both directions before proceeding, which is crucial for preventing accidents. Yielding to cross traffic is vital; it ensures that drivers give right-of-way as dictated by traffic laws, helping to maintain order and safety at intersections.

Other options may suggest inappropriate actions that could compromise safety. For example, increasing speed to pass through the intersection quickly can lead to collisions, especially if other vehicles are present. Similarly, slowing down without stopping fails to comply with traffic laws and does not allow for the necessary precautions at a stop sign. Finally, only stopping if the intersection is crowded ignores the requirement for a complete stop in all circumstances, regardless of traffic conditions.
