What should you do in this situation?

You answered correctly. In this situation, you must allow the pedestrian to cross the zebra crossing first because pedestrians always have priority at marked crossings. Additionally, you should wait before the crossing until the blue vehicle has completed its turn. You must not pull up directly behind the blue vehicle, as this could block the crossing or endanger the pedestrian. Remember, always give way to pedestrians at crossings and keep the crossing clear.
