In which situations are you not allowed to enter a junction even though the traffic light is green?

In this case, it is important to understand the traffic rules concerning entering a junction when the traffic light is green.

The correct answers highlight two situations where you must not enter a junction even with a green light:

1. If you would have to stop in the middle of the junction because traffic is backing up, you are not allowed to enter as this can block the intersection and lead to traffic congestion, violating the principle of traffic flow.

2. If a police officer instructs you to stop, their authority takes precedence over traffic signals, and you must obey their direction, regardless of the traffic light's color.

Your selection included one correct choice (situation 2) but missed the first one, which is crucial for maintaining smooth traffic flow and safety at intersections. Understanding these rules is vital for responsible driving and ensuring that you do not contribute to traffic issues. Always be aware of the surrounding traffic conditions and any authority instructions when approaching junctions.
