# Explanation: Speed and Field of Vision
At higher speeds, the driver experiences a **narrowing of the visual field**, a phenomenon known as tunnel vision. This occurs because the eyes focus more on the direct path and lose the ability to perceive lateral details. Therefore, it is essential to reduce speed in urban areas, curves and adverse conditions to maintain a wider and safer view of the surroundings.
