A traffic calmed commercial zone (verkehrsberuhigter Bereich) starts here. What must you do?

This traffic sign combination shows a "20 km/h zone" along with a "no parking zone" where parking is only allowed with a parking disc for a maximum of 2 hours ("2 Std." means 2 hours).

In such zones, the speed limit is strictly 20 km/h to increase safety, especially for pedestrians. The no parking sign means you cannot park freely; parking is restricted, and if you do park, you must use a parking disc to show your arrival time and cannot stay longer than 2 hours.

This is typical in traffic-calmed zones where pedestrian traffic is heavy, so drivers must be extra cautious, drive slowly, and follow parking restrictions to maintain safety and order.

So the key rules are: watch out for pedestrians, respect the speed limit, and adhere to parking time limits with a parking disc when parking is allowed. This understanding matches why options 1 and 2 in your quiz were correct.
