What should you anticipate in this situation?

Your answer is correct because in this situation, you should expect the other vehicle (such as a bus or cyclist) ahead to move out and cross the center of the road to continue their path. According to German traffic rules, when another road user signals and begins to pull out from a stop (like a bus at a marked stop), you must anticipate this movement and adapt your driving accordingly, often by slowing down or yielding.

You should not brake suddenly without cause if the situation allows for a smooth navigation (which eliminates option 2). Also, overtaking in this situation is dangerous and prohibited if it requires crossing the center line, especially near hazards like unprotected level crossings or merging traffic (which rules out option 3). The key rule is to anticipate and give way when a vehicle signals and moves out from a stop, ensuring safety for all and avoiding collisions.
