Benjamin Franklin said: “Beer is leaving proof that God loves us and wants to see us happy.” He added later: "All things in moderation." That is worth remembering wherever you drink. 

Alcohol affects individuals differently. Your blood alcohol level will be influenced by your age, gender, physical condition, amount of food consumed and any drugs or medication. The altitude where you are drinking makes a difference, as does the strength of the beer. 

Those factors all complicate the ongoing debate about how much you can drink before it is unsafe to drive. However, in most states, if your blood-alcohol limit is above .08% then it is not legal for you to drive, and legal is legal.
