How can you tell if a horse-drawn carriage wants to change direction?

Your answer is completely correct. A horse-drawn carriage can indicate its intention to change direction in several ways: the driver may extend their arm as a signal, show a traffic paddle, or use a flashing indicator if the carriage is equipped with one. All of these methods are permitted and recognized under German traffic regulations. It is important to watch for any of these signals when driving near horse-drawn carriages so you can react appropriately and safely. This knowledge will help you correctly interpret the intentions of carriage drivers in real traffic situations.
