What is the right course of action?

Your answer is correct. According to German traffic rules, when you want to turn right and a cyclist is going straight or has the right of way, you must let the cyclist pass before you turn. This rule ensures the safety of cyclists, who are considered vulnerable road users.

The blue truck on the left does not have priority here since you are not turning left, and the cyclist’s path is more direct and continuous.

Always remember: When turning right, check for cyclists and pedestrians, and give way to them if they have priority. This helps to avoid accidents and ensures smooth traffic flow.
