It is prohibited to overtake on a steep hill:
- Only when there is a “danger” road sign.
- Correct answer: When your field of vision is limited or obstructed.
- Only when there is a “no overtaking” road sign.
- Overtaking is permitted, provided that the weight of your car exceeds 4 tons.
Why this is the answer
The correct answer in the official bank: When your field of vision is limited or obstructed.
Before the crest of a steep hill you cannot see vehicles coming from the other side. Overtaking where your field of vision is limited or obstructed can cause a head-on collision. This ban applies even without a sign, at any time of day and for any vehicle weight, because before overtaking you must see that the road ahead is clear for a sufficient distance.
