Final answer:
At an intersection with a stop sign, one must come to a full stop, check for traffic and pedestrians, and proceed when safe. Ignoring a stop sign can result in vehicular accidents.
Step-by-step explanation:
At an intersection controlled by a stop sign, the correct action to take is to come to a full stop. It is important to stop completely, check for oncoming traffic, and pedestrians, and proceed only when it is safe to do so. A stop sign is used to regulate traffic and ensure the safety of drivers and pedestrians. Ignoring a stop sign can lead to dangerous situations and vehicular accidents. After coming to a full stop, you should give way to vehicles that have arrived at the intersection before you, or those on the main road if you are on a smaller road. You should only proceed through the intersection when it is safe and legal to do so.
