How does alcohol affect a driver's field of vision?

Alcohol significantly impairs various visual functions, including the driver's field of vision. Specifically, it narrows peripheral vision, which is the ability to see objects outside of your direct line of sight. This reduction in peripheral awareness makes it more difficult for drivers to notice fast-approaching vehicles, pedestrians, or other potential hazards that are not directly in front of them.

The narrowing of peripheral vision due to alcohol consumption can contribute to a delay in reaction times and decreased situational awareness, increasing the risk of accidents on the road. It’s important for drivers to understand how alcohol can affect their perception and overall driving ability, particularly their ability to detect and respond to critical incidents in their environment.

Enhancing peripheral vision or having no effect on vision are misconceptions, as alcohol is known for impairing rather than enhancing visual capabilities. The claim that it only affects night vision is also misleading, as alcohol can impair vision under all lighting conditions, not just at night.
