Correct answer
A. Inability to distinguish shapes in the dark and sensitivity to being blinded.
Explanation
In the photo, you are driving at night on an unlit road, and a vehicle with its lights on is coming from the opposite direction. Proper observation of the road is then disturbed by the inability to distinguish shapes in the dark and sensitivity to dazzle - answer A.
The Road Traffic Act requires the driver to drive at a speed that ensures control of the vehicle, taking into account the visibility of the road. At night the eye works in a different mode: it stops distinguishing colours and details, and the outlines of objects outside the reach of your lights merge with the background. After passing a vehicle with its lights on, the eye needs a few seconds to return to twilight vision - the older the driver, the longer it takes - and during this time you are practically driving from memory. On top of that come tiredness and the so-called motorway hypnosis. Answers B and C describe things that improve vision: suitable glasses and good visual acuity. That is why at night you slow down, look at the right-hand edge of the roadway instead of into the headlights of oncoming vehicles, and keep the windscreen and headlights clean.
