You have to fill out a questionaire asking when the last time you used alcohol/drugs, etc. Be sure to remember these dates. You’ll need to use the same ones in the hearing. Your witnesses will too. The hearing officer will give you a packet of forms you need to fill out and things you need to get done. You have a list of certified substance abuse counselors you have to use for an assessment – $65. You’ll have to get an FBI check done. Do this first because it takes the longest. You’ll have to get a set of fingerprints made for the FBI check. Do this at your local police station for a minimal fee. You have to put down information for three witnesses and one alternate, addresses, driving license numbers, etc. The witnesses can not have had a past alcohol/drug related charge. I think this is the major gist of it. Hope it works out for you!
