Full Answer

Blood alcohol levels help determine the level of intoxication of an individual. A person having a blood alcohol level of 0.08 or above is considered legally intoxicated.

The effects of blood alcohol levels vary from person to person. For instance, an individual with a 0.03 blood alcohol level may exhibit more signs of intoxication than a person with a blood alcohol level of 0.05.

In most instances, the blood alcohol level of an individual starts to affect his behavior when he reaches a level of 0.04 or more. By the time blood alcohol levels gets to the point of 0.10, the individual is highly intoxicated, and his motor skills are greatly impaired. In extreme cases, blood alcohol levels of 0.30 or more can lead to a coma and potentially death.

Blood alcohol levels of an individual increases at a rate relative to a person's size and the amount they drink. To keep blood alcohol levels to a minimum, experts advise consuming only a few alcoholic drinks in a single sitting.
