You are on a roundabout. What should you remember?

The selected combination is indeed correct. Each point addresses an important aspect of driving in a roundabout according to German traffic rules:

1. Driving over a central island is only permitted if unavoidable due to the size of your vehicle, which emphasizes the need to navigate the roundabout safely without crossing the island unless necessary.

2. It is prohibited to stop on the roadway in a roundabout, as doing so could disrupt the smooth flow of traffic and increase the risk of accidents.

3. You must indicate when leaving the roundabout to inform other drivers of your intentions, which is crucial for maintaining safe interactions among vehicles.

Recognizing all these aspects helps ensure safer driving and efficient traffic flow in roundabouts. Understanding these rules is key to complying with German traffic regulations.
