Step-by-step explanation:
When operating a vehicle, alcohol can have various effects on the body. These effects can include decreased reaction time, lowered levels of alertness, impaired judgment, and loss of coordination. Excessive alcohol use can also result in a complete loss of consciousness and difficulty remembering events that occurred while intoxicated.
Additionally, alcohol consumption during pregnancy can lead to a cluster of birth defects and symptoms known as fetal alcohol spectrum disorder (FASD) or fetal alcohol syndrome (FAS).
It is important to note that the immediate effects of alcohol can vary depending on a person's blood alcohol concentration (BAC), which can differ based on factors such as age, sex, and pre-existing health conditions.
