A drunk driving conviction can occur very easily even if you feel like you did not have much to drink. The legal limit of .08% BAC is quite low. For many people, this does not equal much alcohol you have to consume to be illegal to drive.
According to the University of Michigan, there is a range of factors that can affect your blood alcohol level, but there are some general guidelines that can help you to avoid an OWI charge on your record.
Before looking into actual alcohol consumption limits, you should be aware that it is very normal to drink much more than you think without realizing it. It is also possible to be under the influence and not aware. This is due to the effects alcohol has on your brain and perception. So, you should never rely solely on how you feel to assess if you are too drunk to drive.
Know the standards
Many factors can influence how your body processes alcohol, but standard guidelines suggest that four 12-ounce servings of beer or one serving of wine or liquor will cause you to be near the legal limit if you weigh around 160 pounds. You should note this is not true in all cases due to the many factors that influence your BAC level.
Understand the impact of gender and weight
Gender and weight are the main factors that influence how alcohol processes in your body and your BAC level. In general, men can consume more alcohol than women and maintain a lower BAC. This is due to physical differences between genders.
A heavier person will process alcohol faster than a thinner person. This is regardless of gender, and again, due to biological factors, specifically metabolism.
