Step-by-step explanation:
Signs of intoxication typically include a variety of physical and behavioral changes such as visual disturbances, slurred speech, drowsiness, impaired judgment, and loss of coordination. These effects result from alcohol's impact on the brain, which can lead to decreased reaction times, decreased levels of alertness, and a reduction in behavioral control.
