You want to leave the [petrol station]. What is correct?

Your answer is correct because when leaving a petrol station (or any property), you must give priority to pedestrians crossing the road. According to German traffic rules, pedestrians always have the right of way at crossings and when they are on or near the road you are entering. This means you must stop and wait if pedestrians are crossing.

The other options are incorrect: you cannot drive in both directions if the exit only allows one direction (often indicated by signs), and you do not have right of way over vehicles coming from the left when entering a road. You must yield to all other road users already on the public road to prevent accidents.

Remember, safety and priority rules protect vulnerable road users like pedestrians first, and you must always check carefully before entering or crossing a public road from private property.
