How can I deter a friend from drinking and driving?

i can help u here but i dont have no websites for u....... what u need to do is just give him the facts about drunk driving...... tell him that you care about him and u dont want to see him go to jail...... tell him that if he continues to drive drunk you are going to go to the police and have him arrested...... if he still continues you have no other options. i say go to the police...... or beytter yet call a rehab center..
