What is the correct response if, when reversing a combination vehicle the view to the rear is impeded?

When reversing a combination vehicle, it is crucial to maintain clear communication and visibility with the person who is directing the maneuver. According to German traffic rules, if the driver loses sight of the person guiding them—for example, if their direct line of sight is blocked—the vehicle must be stopped immediately. This ensures safety by preventing accidents due to miscommunication or the driver not being able to see hazards or directions clearly. The presence and visibility of the person directing are mandatory to support safe reversing in such situations. This rule applies regardless of the location and helps avoid potential collisions or dangerous situations.
