Does the towed vehicle have an effect on the field of vision of the driver?

Yes, a towed vehicle, especially a larger one as shown in the picture, significantly restricts the field of vision of the driver of the towing vehicle. It obstructs the view in the rear-view mirror, creating a large blind spot and making it difficult to assess the situation behind the combination of vehicles. This requires the driver to be particularly careful, especially during manoeuvres such as changing lanes, and to rely mainly on the side mirrors.
