I think we all realize that it is difficult to see someone you care for struggle, but as has been said, most addicts, especially younger ones, don't learn from what we tell them, but from experiencing the consequences of their actions first hand. Family members should all be on the same page as it appears his mom is enabling by covering his expenses ,etc, so he has a cushion. I've talked with addicts who have had to ride the bus or train and every day they do so, they are reminded that actions have consequences and they appreciate the privilege of being able to drive that much more and perhaps will take steps to preserve it. If he is an adult and is treated as such, yes he will be unhappy about not being able to drive, but once he gets through it, he might think twice before getting behind the wheel with alcohol or drugs on board. I think currently, you can't escape DUI charges across states as there is a national database. It is a serious public safety issue. Just remind him in a compassionate way that if he follows the conditions of his suspension, he will be able to drive again and find a non judgmental way to connect the behavior with the consequences.
