What action is required at a stop sign?

Answer: B — Come to a complete stop and look for cross traffic

At a stop sign, the law requires drivers to come to a complete stop before the stop line, crosswalk, or intersection. This action ensures that drivers have the opportunity to assess the situation fully and look for cross traffic or pedestrians before proceeding. By making a complete stop, the driver can judge the right of way and ensure it is safe to move forward, thereby reinforcing road safety and compliance with traffic laws. This approach is essential for preventing accidents and maintaining order on the road, as it allows for clear visibility and awareness of any potential hazards. The action of simply slowing down or proceeding if clear does not meet the safety requirement needed at a stop sign, nor does yielding only to the right or stopping only if other vehicles are present. Effective navigation at a stop sign hinges on the complete stop, making it crucial for all drivers to adhere to this rule.
