Stop sign
The driver of any vehicle approaching a stop sign at the entrance to, or within, an intersection, shall stop at a limit line, if marked, otherwise before entering the crosswalk on the near side of the intersection.
Important
As you approach the intersection, you see there aren't any cars around, you must come to a complete stop anyway.
