For answer  A 

The visual field of the driver is reduced significantly along with the increase of the travel speed, a phenomenon known as “tunnel vision”. This physiological adaptation has the role of focusing visual attention on the road ahead, thus reducing peripheral perception in order to minimize distraction from possible immediate dangers.

At high speeds, the eyes and brain adapt to process central information more quickly, neglecting peripheral details. Studies have shown that at speeds of 100 km/h the visual field can begin to narrow considerably, and at speeds of 300 km/h the visual field can be drastically reduced, with an almost exclusive concentration on the central area of the visual field.

It is important to remember that along with the increase of speed, risks also increase, because reaction time becomes critical within a more restricted visual angle.

For answer  B 

The dimensions of the windshield and of the rear window do not influence the visual field, they can only obstruct it, plus these dimensions of the windshield and the rear window do not change while driving.

For answer  C 

The objects located in the visual field or their size, such as small-sized road signs, do not influence the visual field.

The correct answer is: A
