What is one effect of impaired judgment due to alcohol consumption?

Impaired judgment due to alcohol consumption significantly affects a person's ability to make safe decisions. When alcohol is consumed, it influences the brain's capacity to evaluate situations accurately, respond to external stimuli, and make sound judgments. This impairment can lead to risky behaviors, such as driving recklessly, misjudging distances, or failing to react appropriately to dangers on the road, significantly increasing the likelihood of accidents.

The other options suggest positive effects that are not associated with alcohol consumption. Improved focus on driving, increased awareness of surroundings, and enhanced coordination would typically be expected to contribute to safe driving, but alcohol impairs all of these abilities instead, highlighting the severity of its effects on driving performance.
