Final answer:
If traffic is blocking the intersection at a green light, you should stay out until traffic clears to avoid gridlock and ensure pedestrian safety.
Step-by-step explanation:
When you have a green light, but traffic is blocking the intersection, you should stay out of the intersection until traffic clears. This is the safest and most legal option to take in this scenario. When you enter an intersection, you must ensure that you can clear it without stopping. Entering the intersection only to become stuck in traffic can lead to gridlock and can be particularly dangerous for pedestrians who may be trying to cross, as it disrupts the usual flow of traffic and compromises safety. Pedestrian safety is important, especially in areas where many students or others are crossing, and a congested intersection poses a higher risk to them. Additionally, changing lanes or attempting to go around traffic can be unsafe and may also violate traffic laws. Therefore, the best course of action is to wait behind the stop line until there is enough space on the other side of the intersection for your vehicle to pass through completely.
