You are driving through a tunnel. What special aspect applies here?

In a tunnel, several key aspects need to be considered for safe driving.

1. **Loud Vehicle Noise**: This can be distracting, especially in enclosed spaces like tunnels where sounds may echo. It is important to remain focused despite potential distractions.

2. **Signposted Safety Devices**: Tunnels are equipped with safety devices, such as emergency exits and telephones, which are clearly marked. Knowledge of these locations is crucial for emergencies and ensuring safety.

3. **Lighting Effects**: The lighting in tunnels can vary and may cause visual distractions or difficulty in adjusting your eyesight. This is another reason to stay alert and aware when driving through a tunnel.

Recognizing all three aspects helps ensure not only your safety but also the safety of others. Understanding and adhering to this combination is essential according to German traffic regulations, which emphasize safe driving practices in specific environments.
