What should you do as you draw near to this heavy goods transport?

Your answer is correct because in German traffic rules, when approaching a heavy goods transport (especially an oversized or special transport as shown here), you should move into the right-hand lane if possible to give them space and refrain from overtaking. This ensures safety for all road users and accommodates the special transport's potentially limited maneuverability. Overtaking such vehicles, even with extra care, is generally discouraged due to the increased risk. Following these steps helps prevent accidents and keeps traffic flowing smoothly.
