Where is stopping prohibited?

You selected both answer 1 (Outside parking areas on autobahns and clearways for motor vehicles only) and answer 2 (Near or on sharp bends), which are both correct. Stopping is prohibited outside designated parking areas on autobahns and clearways because it creates a significant danger for fast-moving traffic. Similarly, stopping near or on sharp bends is forbidden since it limits visibility and increases the risk of accidents for other drivers approaching the bend. Stopping at bus stops, however, is not always prohibited—short stops may be allowed, for example, for picking up or letting passengers out, unless a specific sign forbids this. For future questions, always think about whether stopping would endanger or significantly obstruct other traffic.
