Alcohol affects the central nervous system of the driver.
Even at a level of 0.05 percent alcohol in blood, the sense of judgement is impaired and the ability to control steering is affected. Abuse of alcohol results in increased incidence of traumatic vehicular injuries and deaths. Of all the drugs, alcohol is the only drug whose self-induced intoxication is socially acceptable. Alcohol is rapidly absorbed from the stomach and small intestine. The presence of food in the stomach inhibits the absorption of alcohol because of dilution.
