How can you preserve the clutch components of motor vehicles with a manual gearbox?

The selected combination is correct because both of these practices help in preserving the clutch components.

Selecting the neutral gear while waiting to move relieves pressure on the clutch, preventing unnecessary wear. This is important in German traffic regulations which aim to encourage efficient and responsible driving practices.

Manoeuvring with a low engine speed helps to reduce the strain on the clutch, further extending its lifespan. Using the appropriate combination of gears in various driving conditions is essential to maintaining vehicle performance and safety on the road.

Neglecting to do so can lead to premature wear and costly repairs, which is why understanding these practices is crucial for any driver.
