When may a tram be overtaken on the left?

The combination of choices 1 and 2 is correct because, according to German traffic rules, you may overtake a tram on the left in specific circumstances.

In one-way streets (choice 1), it is permissible to overtake since there is no oncoming traffic and space is typically provided.

When the rails run too far to the right (choice 2), overtaking on the left becomes necessary for safe passage; this generally refers to situations where the tram is positioned closer to the center of the road, allowing for safe overtaking on the left side.

Choice 3 is incorrect because it describes a situation where the roadway to the right of the tram is blocked. In such cases, overtaking would not be possible or legal, as it requires appropriate space to maneuver safely.

Understanding these conditions is vital for promoting road safety and ensuring a smooth flow of traffic, especially concerning trams, which are common in many urban areas in Germany.
