Difficulty: EasyPhysiological Effects of Alcohol on Driving Performance

Alcohol consumption impairs a driver's peripheral vision, narrowing their visual field and creating a 'tunnel vision' effect that reduces awareness of hazards approaching from the sides.

Answer: Answer

Answer

True. Alcohol depresses neural activity and slows eye muscle coordination, narrowing a driver's visual field and diminishing peripheral awareness.
The statement is correct because alcohol depresses central nervous system activity, impairing the eye muscles and reducing peripheral vision, which creates a narrowing 'tunnel vision' effect.

Step-by-Step Solution

1
Examine the impact of alcohol on central nervous system processing and ocular control.
Alcohol acts as a depressant, impairing eye muscle coordination and slowing visual information processing in the brain.
Peripheral vision relies on quick, coordinated responses from eye muscles and rapid neural signal transmission.
2
Determine the functional visual effect on driving performance.
The driver experiences a reduced visual field ('tunnel vision'), making it harder to detect vehicles, pedestrians, or road hazards outside their central line of sight.
This confirms that alcohol impairs peripheral vision and side-hazard awareness.
