If someone has say ... 2 beers ... is it okay to drive?
Dont ask. Just answer.
No. As they say "buzzed driving is drunk driving". Any alcohol impairs your judgement. If you have a drink, don't drive!
It depends on the size and weight of the person
1 beer an hour is a general rule of thumb...also make sure you have some food in your stomach as well!!
It depends on the person,weight,and age
