Right answer and explanation
Right answer: D. For several seconds after the vehicle has gone past
After strong dazzle the eye takes several seconds to recover. At 80 km/h you cover more than 20 metres a second, so you can travel a hundred metres with badly reduced vision. That is why you look towards the right-hand edge during the meeting and slow down — beforehand, not afterwards.
