What do you have to consider when parking your motorbike?

The selected combination is correct because when parking a motorbike, it's essential to ensure it does not obstruct anyone and is stable, preventing it from falling over. According to German traffic rules, motorbikes should be parked in a way that maintains the safety and convenience of pedestrians and other road users. Obstruction can lead to fines or accidents, while ensuring the bike does not fall over is crucial for preventing damage to the bike and surrounding property. The third option, parking on the sidewalk, is not permitted unless there is a designated area, as it can impede pedestrian movement. Thus, parking regulations aim to balance the needs of all road users.
