What is the right course of action now?

Your answer is correct because in German traffic rules, when you want to turn right and there is a cyclist approaching from behind or alongside, you must first allow the cyclist to pass through safely before turning. This prevents collisions and respects the cyclist's right of way if they are already continuing straight or turning ahead.

Additionally, glancing over your right shoulder before turning is important for checking your blind spot to ensure no pedestrians, cyclists, or other vehicles are alongside you that you might not see in your mirrors. This is a key safety step before making a right turn.

The option about taking the turn ahead of the electric scooter would be unsafe and is not recommended, as it could lead to a collision or force the scooter to brake suddenly. German traffic rules prioritize safety and yielding to more vulnerable road users like cyclists and scooters when turning.

In summary, always yield to cyclists or other traffic that has priority, signal in good time, and check your blind spot before turning right. This ensures safe and legally compliant driving in Germany.
