So they tell him to blow, if he refuses, they can't do anything to him, they take him home and he realizes the social worker, she won't do anything, because there is no proof that he drank - he didn't blow. If he blows, they will take him home or to the hospital, depending on his condition and alcohol level. She notifies the social worker and she tells you that your 17-year-old son sucked some **** with his friend. I ordered our 17 not to blow, he also has some **** once in a while, but he never came drunk, he would get it. ) It's the worst age, I understand your concern, but let's remember ourselves at 17, who among us didn't drink here and there? :-)
