In the depicted scenario, are you permitted to overtake this vehicle?

In the video, you are driving on a two-way road with one lane in each direction, with a barrier on the right; a dark car is in front of you, and the road goes uphill and the next section cannot be seen beyond the top of the hill. You are not allowed to overtake this vehicle. The answer is: no.

The Road Traffic Act prohibits overtaking a power-driven vehicle travelling on the roadway when approaching the top of a hill; on a two-way roadway, the exception applies only to a section with marked lanes and only when the driver does not enter the part of the roadway intended for the opposite direction where road markings prohibit this. Here the roadway has no marked lanes, so the exception does not apply, and any overtaking means driving in the lane for oncoming traffic - at a place where you cannot see beyond the hill whether someone is coming. The Act also requires adequate visibility and sufficient space before overtaking, and the hill takes away both: a car coming from the opposite direction will appear only when it is a few dozen metres from you, and the barrier on the right will leave you no room to escape. So you stay behind the car and overtake only after the hill, when you see a long, empty stretch.
