You are driving at 100 km/h on a road not inside a built-up area. In front of you a truck is travelling at 70 km/h. What is the minimum distance you must be from a crest in the road when commencing an overtaking manoeuvre?

In Germany, when overtaking on a road outside built-up areas (where you are driving at higher speeds like 100 km/h), safety distances are crucial. The law requires that you only start overtaking if you can clearly see an unobstructed stretch of road ahead, so you have enough space and time to complete the maneuver safely.

Specifically, when approaching a crest (a hilltop where visibility is limited), you must ensure there is at least 800 meters of clear sight distance before you begin overtaking. This distance allows you to see any oncoming traffic early enough to avoid dangerous situations.

Therefore, the minimum distance from a crest before overtaking at 100 km/h is 800 meters. This rule helps prevent accidents caused by limited visibility on hilly roads.
