1.8

So, let’s think about this for a minute.
This chart, which you often see arriving in the mail with your driver’s license renewal notification, shows how many standard-sized drinks a male or female, at different body weights, would need to drink to get to specific BAC levels.
This illustrates very well how alcohol affects a smaller person compared to a larger person and how it affects males versus females.
The most striking point it shows is that a person can become intoxicated and drive impaired after just one drink.
After two drinks, they can be considered legally intoxicated, and too intoxicated to legally operate a vehicle in California.
Now compare that to the previous screen which shows the effects different BAC levels have on a person.
It shows that a 180-lb male who consumes two standard-sized drinks could be experiencing impairment of his balance, speech, vision, and control.
In this scenario, he could be considered legally intoxicated and unable to lawfully drive in California. Three drinks would likely bring his BAC level up to legal impairment levels.
