What behavior is commonly seen in drivers under the influence of alcohol?

Drivers under the influence of alcohol often exhibit frequent lane changes. This behavior can be attributed to impaired judgment, reduced coordination, and a lack of awareness of their surroundings, which contribute to erratic driving patterns. Alcohol can lead to overconfidence, making drivers feel capable of maneuvering their vehicle recklessly. As a result, they may not accurately assess their speed or the position of other vehicles on the road, leading to sudden or impulsive lane changes that can create dangerous situations.

In contrast, increased attention to details and consistent driving speed would generally indicate a driver is in control and fully alert, which is not the case for someone intoxicated. While a calm demeanor might seem plausible, alcohol often leads to heightened emotions or increased risk-taking behavior rather than a composed state.
