If you have a green light but the intersection is blocked, what is the best action to take?

When facing a green light but finding the intersection blocked, the best action is to stay out of the intersection until the traffic clears. This is a fundamental principle of safe driving known as the "gridlock rule." It ensures that drivers do not impede the flow of traffic or create further congestion in the intersection.

Remaining outside the intersection allows other vehicles to move through more easily, promoting smoother traffic flow. Entering an intersection where vehicles are already stopped can cause a traffic jam and potentially lead to accidents, as it could block cross traffic or prevent emergency vehicles from passing. Additionally, staying out of the intersection helps to comply with traffic laws that require drivers to only enter intersections when they can clear them entirely, thereby enhancing safety for all road users.
