A driver who has consumed alcohol attempts to turn across traffic, misjudging the gap before an oncoming car arrives. Which physiological effect of alcohol directly impairs a driver's ability to accurately gauge the distance and position of approaching vehicles?
- Impairment of binocular visual coordination and depth perceptionCevap
- BExpansion of peripheral vision beyond normal field limits
- CAcceleration of eye muscle reflex movement and dynamic acuity
- DIncreased sensitivity of retina rod cells to low-light illumination
Cevap
Impairment of binocular visual coordination and depth perception directly reduces a driver's ability to judge distances.
Depth perception requires accurate binocular vision and synchronized eye muscle movement. Alcohol depresses the central nervous system, impairing muscle coordination in the eyes and making it difficult to judge how far away another vehicle is or how fast it is approaching.
