You are driving in a built-up area behind a vehicle with number plates that are not local. What could happen?

The selected combination is correct because it addresses multiple potential risks when driving behind a vehicle with unfamiliar number plates in a built-up area.

1. A vehicle might brake unexpectedly due to a lack of local knowledge, leading to sudden stops.
2. Drivers not familiar with the area may activate their turn signals too late, which can confuse other drivers and increase the risk of accidents.
3. Some drivers may stop unexpectedly to ask for directions, posing a hazard to following vehicles.

In Germany, traffic regulations emphasize the importance of anticipating the actions of other drivers, especially those who may not be experienced with the local road layout. Being aware of these possibilities helps ensure safety and proper driving etiquette.
