You are driving a slow-moving vehicle on a main road. How can you facilitate faster-moving vehicles in overtaking?

When driving a slow-moving vehicle on a main road, it is important to allow faster-moving vehicles to overtake safely. The correct actions include moving onto the hard shoulder, parking area, or into a lay-by. These options are viable because:

1. **Hard Shoulder:** This area is designated for emergencies or slower vehicles. Using it allows faster traffic to pass without being impeded.
2. **Parking Area:** This option provides a safe space for you to pull over briefly, facilitating overtaking.
3. **Lay-by:** These are specifically designed for vehicles to stop and allow others to pass, making it an ideal choice to facilitate overtaking.

According to German traffic regulations, drivers of slower vehicles have a responsibility to enable uninterrupted flow of traffic wherever possible. Selecting all these options demonstrates an understanding of road safety and consideration for other drivers. Adhering to these rules helps maintain overall traffic efficiency and safety.
