Can an increase of speed affect a truck driver's perception?
Explanation
Correct answer: Yes, a higher speed causes a change of perception.
As speed increases, the driver's field of vision narrows, and their peripheral vision becomes less clear. This phenomenon, known as tunnel vision, causes the driver to focus on a more distant section of the road. This can result in the delayed perception of a hazard appearing in an adjacent traffic lane or on the verge.
