I have a question. When driving on the German highway, if I want to stop to take photos, do I need to see a parking sign before I can stop, or can I stop as long as there is no no-parking sign ?

You must park in the parking area.

You must park in designated areas, otherwise it's quite dangerous.

There shouldn't be a prohibition on stopping.

If you drive in Germany, you will know that the markings are very clear. Whether in the countryside, city or expressway. Parking can only be in parking areas, unless it is an emergency stop, at which time passing vehicles will stop to help you. Be sure to avoid temporary braking, lane changes, etc. I have seen local people park on the side of the road, and they park their cars in the grass on the side of the road in an exaggerated manner, even at an angle.

National highway rest areas are still quite a few, with reminders of P several hundred meters, park it, and the general speed limit on the national highway is 100, 70, so parking on the side of the road is still very dangerous.

All are single-lane roads, you must park in the parking area and cannot park randomly.

First of all, there will be some rest areas for parking, which are generally equipped with wooden tables and chairs. Or on the roadside with a wider protrusion, but it should not affect others driving.

On the national highway, cars also drive very fast. Safety first, must stop at a place where you can park.

Need to park in the parking bay
