It is important to note that even a BAC of 0.02% can impair your ability to drive safely. Alcohol affects your coordination, judgment, and reaction time, which can increase your risk of being involved in a car accident.
If you are planning to drink alcohol, it is important to plan ahead for how you will get home safely. You should never drink and drive, even if you think you are only slightly impaired. There are many options for getting home safely after drinking, such as taking a taxi, using a ride-sharing service, or designating a sober driver.
