Does speed influence the driver's field of vision?
A)Yes; the field of vision decreases as speed increases.Correct
B)No.
C)Yes; the field of vision widens as speed increases.
As speed increases, the field of vision decreases. This is because the driver focuses more on what is directly in front of them and loses peripheral vision, which reduces their ability to detect lateral hazards. That is why the correct answer is option a) Yes; the field of vision decreases as speed increases.
