Individuals that drink and drive worry about the number of drinks they may have in order to be considered under the legal limit.  There are various factors such as weight, type of drink, food consumption, etc that determine the level of intoxication.  However, there are some general guidelines that help to determine the number of drinks a person may have before they are considered intoxicated. 

What Is Blood Alcohol Concentration (BAC)?

This is the amount of alcohol in a person’s body in relation to the amount of blood in their system.  For example, a BAC level of .20 means 1 part per 500 in a person’s blood alcohol level.  The chart below can help a person to determine their BAC.

Approximate Blood Alcohol Percentage

Subtract .01% for each 40 minutes of drinking.  One drink is 1oz. of 100 proof liquor, 12 oz. of beer, or 4 oz. of wine.  Food, fatigue, medications, and other conditions may change the levels of intoxication. 

Should I Consult an Attorney?

An experienced DUI /DWI lawyer can be extremely helpful in DUI cases.  These defense attorney can help to evaluate the evidence against a suspect and determine whether the field sobriety tests were administered correctly.  In addition, experienced criminal defense attorneys might be able to reduce any penalties imposed on first time offenders.
