Which of the following best describes how euphoria from alcohol can affect driving?

Euphoria from alcohol can significantly impair a person's ability to drive safely by leading to overconfidence. This state of heightened mood and inflated self-esteem often causes individuals to underestimate risks and overestimate their abilities. As a result, drivers may engage in reckless behaviors, such as speeding, ignoring traffic signals, or taking unnecessary risks, believing they are capable of handling the situation better than they actually are.

The other options do not accurately reflect the effects of alcohol-induced euphoria on driving. For example, the idea that it improves decision-making contradicts established research indicating that alcohol typically impairs judgment and cognitive function. Claiming that it has no effect on driving overlooks the substantial evidence linking alcohol consumption, even at low levels, to decreased driving performance. Lastly, stating it decreases driving speed is misleading, as overconfident drivers might actually increase their speed, putting themselves and others at greater risk on the road.
