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

The combination of all three options is correct because they represent the various signals a horse-drawn carriage driver can use to indicate a change in direction.

1. Extending an arm is a common signal among drivers to communicate their intentions to other road users.
2. A traffic paddle, displaying a specific message, is an official signaling method that alerts others on the road about the driver's action.
3. A flashing indicator is a modern feature seen on many horse-drawn carriages, providing a clear visual cue similar to those used in motor vehicles.

According to German traffic regulations, it’s important for drivers of non-motorized vehicles, like horse-drawn carriages, to use all available means to ensure the safety of themselves and other road users. Using these signals helps prevent accidents and misunderstandings on the road. Therefore, recognizing all three signaling methods is crucial for understanding how to drive safely near such vehicles.
