Which of the following scenarios allows for overtaking on the right?

Overtaking on the right is generally prohibited in most circumstances, but there are specific situations where it can be acceptable. When a tram is present, particularly if it is stationary and you are allowed to pass it on the right, this creates a valid scenario for overtaking. Trams often have designated tracks, and when they stop to let passengers on or off, vehicles may legally pass them, provided it is safe to do so and there is enough space. This is in place to maintain public transport efficiency and safety.

In contrast, overtaking while following another vehicle is typically not allowed because it can create a dangerous situation if the lead vehicle suddenly changes lanes or stops. Similarly, overtaking when the traffic light is red is prohibited, as all vehicles must stop. Lastly, simply having a clear road does not justify overtaking on the right unless it adheres to specific road rules, which predominantly cater to overtaking on the left in most driving contexts.
