What is your Blood Alcohol Content (BAC) level? Are you too drunk to drive? How many hours before you can drive? This blood alcohol calculator estimates blood alcohol level based on your weight, gender, and number of drinks you’ve consumed. It also estimates the time before your blood alcohol drops to levels allowable for driving.
It is illegal to drive when your blood alcohol level is 0.08 or higher in all states for anyone age 21 or older. It is illegal for anyone under the age of 21 to buy, possess, and consume alcohol in all states. Zero-tolerance laws also makes it a crime for people under the age of 21 to drive with blood alcohol level from 0 to 0.02 depending on the state.
Some states also impose enhanced penalties for extremely high blood alcohol levels. These levels are typically two or three times the allowable level of 0.08 and varies from state to state.
It is important to note that this blood alcohol content calculation is only a crude estimation. There are many factors affecting the blood alcohol level and time required to reduce that level to allowable limits. This blood alcohol calculator should only be used as a rough estimator.
