A blood alcohol level chart is one that can help assess if a person is considered to be over the legal drinking limit in accordance to the national BAC standard. The blood alcohol level chart may prove to be quite handy in the event that there is no access to a breathalyzer device. However, an important aspect to consider that is that the blood alcohol levels on the blood alcohol level chart are mere approximations. Blood alcohol levels can only be more exactly determined by blood alcohol testing.
The blood alcohol level chart provides for a concise breakdown as to how a certain amount of drinks is to affect people. The blood alcohol levels are determined by the sex and weight of the individual. Furthermore, a blood alcohol level chart may also be constructed having in mind a particular type of alcohol, such as liquor, beer, or wine. The blood alcohol levels will be determined based on the amount of alcohol by volume, which will differ on the type of alcohol. For general purposes, the blood alcohol level chart will often define one drink as one shot of 80 proof liquor, 12 fl oz of beer, and 5 fl oz of table wine.
Determining a person’s blood alcohol levels is done by finding the appropriate body weight and amount of drinks a person has consumed. Usually, there will be two separate blood alcohol levels for men and women. Generally speaking, three drinks will be the legal limit for women, while four drinks will be the legal limit for men.
