When a pedestrian drags or pulls a moped, they must obey the **signals that affect vehicle drivers**. This is because, even though the moped is not being ridden at that moment, it is still considered a **vehicle**.

- Mopeds, like other vehicles such as bicycles and special vehicles, have specific rules about where they must travel, such as using the shoulder when there is no lane designated for them. This reinforces the idea that, even when they are not moving by their own engine, they are still treated as vehicles.

- In traffic situations, traffic signals are designed to regulate the flow of **vehicles** and ensure safety on the road. Therefore, a moped, even if dragged by a pedestrian, must follow the same signals as any other vehicle on the road.

In summary, when dragging a moped, the pedestrian must follow the signals directed at vehicle drivers, as the moped is still considered a vehicle in terms of road regulation.
