What should you do if you start feeling tired while driving?

The selected combination of taking a break straightaway and getting out of the car to move around in the fresh air is correct because both actions address the critical need to combat fatigue while driving. According to German traffic regulations, drivers are encouraged to take regular breaks on long journeys to ensure they remain alert and focused. By taking a break, you give yourself the chance to rest and recharge. Moving around in the fresh air helps stimulate your body and mind, reducing drowsiness and improving your overall alertness.

Listening to stimulating music, while it might provide a temporary distraction, does not effectively combat fatigue. It is important to prioritize physical rest and activity over attempting to stay awake through distraction-based methods. Thus, the combination of the first two options aligns with safe driving practices in Germany and contributes to road safety.
