Which generally describes the effect of alcohol on driving performance?

The correct response highlights that alcohol tends to worsen vision and reduce judgment, which are critical elements in driving performance. When an individual consumes alcohol, it affects the central nervous system, leading to impairments in various cognitive and physical abilities.

Firstly, vision can be significantly compromised; alcohol consumption can cause blurred or double vision and impede depth perception. This makes it more challenging for drivers to accurately gauge distances, judge the speed of oncoming traffic, and respond appropriately to changing road conditions.

Secondly, alcohol reduces judgment, which is essential for making quick decisions while driving. Impaired judgment can lead to overconfidence, causing drivers to engage in risky behaviors such as speeding, aggressive driving, or failing to obey traffic signals.

Understanding these effects is crucial for recognizing the dangers associated with drinking and driving and underlining the importance of sober driving for safety on the roads.
