What can result from listening to very loud music while driving a car?

Listening to very loud music while driving can significantly impair a driver's ability to detect important auditory cues, such as sirens from emergency vehicles or the sounds of nearby traffic. This is why the first option is correct; it highlights the danger of not being aware of your surroundings.

Additionally, loud music can disturb other road users, creating a nuisance. This is the second correct option. German traffic laws emphasize the importance of maintaining a safe and respectful environment on the road, which includes being considerate of others' peace and safety.

The combination of these two factors is crucial as they both address safety and the social responsibility of drivers. By understanding these points, you can appreciate the importance of keeping volume levels at a manageable level when driving, aligning with the recommendations outlined in German traffic regulations.
