At a speed of 60 mph, how much is a driver's field of vision reduced compared to when they are stationary?
As a vehicle's speed increases, the driver’s field of vision significantly constricts. At 60 mph, the field of vision shrinks to about one-fifth of its size compared to when the vehicle is not moving. This reduction limits the driver's ability to perceive peripheral hazards and necessitates increased focus straight ahead. Navigating at high speeds requires heightened attentiveness to detect and react to potential dangers promptly, as the narrow field restricts situational awareness.
