In this scenario, as you near the crest of a hill on a two-way road, are you required to refrain from overtaking the motorbike?

Explanation
Correct answer: Yes
Yes, when approaching the crest of a hill on a two-way road you must refrain from overtaking the motorcycle. The photo shows a two-way road with crash barriers, climbing towards the crest of a hill, with a motorcycle travelling ahead of us. Under art. 24 para. 7 pt. 2 of the Road Traffic Act, overtaking is prohibited when approaching the crest of a hill, because the limited visibility beyond the top makes it impossible to judge whether the manoeuvre is safe.
