What must you watch out for when you drive into an underground car park?

The combination of choices you selected is entirely correct and captures the key considerations when driving into an underground car park.

1. Adjusting to lighting conditions is crucial as the shift from bright outdoor light to the darker environment of a parking garage can impair visibility. This aligns with the need for drivers to be cautious and adapt to changing conditions, as highlighted in German traffic regulations.

2. The presence of pedestrians in car parks is a significant safety concern. It is common for pedestrians to walk in vehicle lanes, and drivers are required to maintain vigilance to prevent accidents, as per safety guidelines set by the German Road Traffic Regulations (StVO).

3. Being aware of possible tire damage from narrow entrances and exits is also important. Many underground car parks have tight spaces that can pose a risk to vehicle tires, making it essential for drivers to proceed slowly and carefully.

By understanding and responding to all these factors, you ensure safety and compliance with traffic regulations in Germany, which aim to protect both vehicle operators and pedestrians.
