What is the right course of action when reversing?

Your answer is fully correct because all these actions are essential when reversing a vehicle according to German traffic rules. First, you must ensure the road area is safe by looking all around you, not just using mirrors, because hazards can come from any direction. Second, driving slowly and attentively is crucial to maintain control and react quickly to any obstacles or pedestrians. Third, checking your blind spots ensures that no person or object is hidden from your mirrors. Combining these steps helps prevent accidents and ensures safe reversing. Remember, careful observation and cautious movement are key when backing up.
