Final answer:
When you see an octagonal-shaped sign at an intersection, it means that you must come to a complete stop and yield the right of way to other vehicles and pedestrians.
Step-by-step explanation:
When you see an octagonal-shaped sign at an intersection, it means that you must come to a complete stop. This is a stop sign. You should wait until it is safe to proceed before entering the intersection.
If there are other cars already at the intersection, it is important to yield the right of way to them before proceeding. You should also be cautious of pedestrians and make sure that they have safely crossed the intersection before you proceed.
Examples:
- If you are driving and approach an intersection with a stop sign, you must come to a complete stop behind the stop line or crosswalk.
- If there is a car already at the intersection, you should wait for them to go first, as they have the right of way.
