In New York, you already are. 2 pints can put you over the 0.05 limit.
People don't realize how little it takes to hit that limit so they drive and get nailed at the checkpoints. Making the limit 0 would make people know not to drink at all before driving. This is the defacto law anyway.
I fyou make it 0, it won’t account for various medical issues and such. You have to account for error as well.
In NY the limit is .08. But your right, two pints will put me dangerously close. However, making the limit 0 will only put more photos in the paper.
