Final answer:
Increasing vehicle speed decreases your field of vision because you need to focus more on the road ahead, which narrows the visual field and makes it harder to notice cross traffic and other potential hazards.
Step-by-step explanation:
Increasing your vehicle's speed does not increase your field of vision; rather, it decreases your field of vision. This is because higher speeds narrow your visual field due to the need to focus more on what's directly ahead to manage reactions and vehicle control. In contrast, a lower speed allows for a broader view, making it easier to perceive potential hazards such as cross traffic. Traffic signals are designed to control vehicle speeds at intersections, ensuring that drivers cannot simply speed through without regard to traffic conditions. The relationship between vehicle speed and stopping distance is also critical; the greater the speed, a vehicle requires a significantly longer distance to come to a complete stop, as indicated by the non-linear relationship between speed and stopping distance.
