Thread Summary
The discussion centers on a motorbike license question (class A) about the minimum distance from a crest when starting to overtake a truck ahead at 70 km/h while the rider is at 100 km/h on a road outside built-up areas. The thread shows a lively mix of reasoning, practical cautions, and debate about the correct number.
Key viewpoints and conclusions
- The most commonly debated figure is 800 m. Several posts argue this is the “gesuchte Antwort” for the exam, while others question the exam wording and realism.
- Other participants suggest different numbers (around 400 m or 200 m), often arguing that the exact distance depends on factors like vehicle length, acceleration, and whether Siegeschichten gelten. This reflects disagreement about a one-size-fits-all answer.
- A practical takeaway in the thread is that overtaking requires significantly more space than beginners expect. Several posters emphasize that you should not overtake if the crest is unclear or if there isn’t ample margin for error.
- Several users advocate using a teaching method called the “Kontrillrechnung” (counter-check calculation) or rough estimates based on speeds and lengths (e.g., assuming a typical LKW length around 15 m, and using relative speeds). These methods are presented as safe-learning tools rather than exact real-world prescriptions.
- The discussion references learning materials and sources:
- Some participants point to the Führerschein-Bestehen explanations and to a Degner book for how the calculation is taught.
- Leitpfosten and simple distance estimation (e.g., 50 m between posts) are suggested as rough real-world cues, though not as exam answers.
- Open questions and disagreements:
- There is no universally accepted official distance cited in the thread beyond individual claims; several participants note ambiguity in exam questions and in how the numbers are presented (units and conditions).
- Real-world applicability versus exam framing: many participants view the exercise as a learning aid to sensitize about space needs, not a perfect instruction for every overtaking scenario.
- Some participants warn that the group dynamics and peer influence can affect how people approach overtaking decisions in practice.
Notable points for readers
- If you’re studying for the exam, be aware that 800 m is frequently cited in this thread as the expected answer, but be prepared for other interpretations or uncertainties in official wording.
- In practice, rely on a broad safety margin and avoid overtaking near crests or when visibility is compromised; use the conceptual idea of “more space than you think” rather than a fixed rule.
- Use the cited study aids (Kontrillrechnung, Anhalteweg concepts, and the Degner/learn-to-drive materials) to understand the underlying reasoning, while recognizing that real-world conditions will vary.
