What indications mean you should interrupt your journey?

The combination of indications you selected is entirely correct. According to German traffic regulations, these signs are indicators that you should seriously consider interrupting your journey due to drowsiness or a lack of focus.

Frequent yawning (indication 1) can signal fatigue, difficulty keeping your eyes open (indication 2) is a clear sign of being too tired to drive safely, and difficulties staying in lane (indication 3) suggest a significant loss of control, which can lead to accidents.

These signs emphasize the importance of responsible driving and recognizing when to take a break to ensure safety on the road. It's crucial to pay attention to these symptoms to avoid dangerous situations.
