What should drivers do when approaching a stop sign?

Answer: B — Come to a complete stop

When approaching a stop sign, drivers are required to come to a complete stop. This action is vital for ensuring safety and adherence to traffic regulations. Coming to a full stop allows drivers to assess the intersection for any oncoming traffic, pedestrians, or other potential hazards before proceeding. It's a common legal requirement across different jurisdictions that helps prevent accidents and ensures that all road users have the opportunity to move safely through intersections. Other choices imply methods that bypass this important safety measure, such as speeding through or merely slowing down, which could lead to misunderstandings of right-of-way, increase the risk of accidents, and potentially lead to legal repercussions for not fully complying with stop sign regulations. Thus, stopping completely is the only appropriate action at a stop sign to promote safety and responsible driving.
