5-7-10 year DUI rules?

Ok,so in 2012 I asked a question about my son who got a DUI at the time, I got some good answers but years have passed since then and I need some things cleared up. The topic of driving came up again and there are too many varied answers to this question. So here we go.... The DUI arrest/ticket was issued on 05/2010, a plea for supervision was entered on 11/2010, and all classes/ court supervision was finished on 11/2011. It is my understanding that many doors open at the 5 year mark BUT, does the 5 year mark count on the arrest date or when everything was said and done. SO in this case does the 5 year mark begin this year on 11/2015 (5 years from arrest date) or in 11-2016 (5 years since supervision was completed).? OH and by the way somehow the license was never suspended. Do not know but somehow someone overlooked something and when they finally asked to suspend my sons license on the last court date where he proved the one year supervision was completed, the judge denied it and the suspension of his license never occurred. Blind luck is all it was there since at the time the new law stated that he was supposed to have a mandatory year long suspension. even the lawyer did not know what happened. However I do not know if that can benefit him somehow since the license was never suspended?

 

so if he entered the guilty with court supervision plea on 11/2010, that means 5 years will come up this November? That makes the most sense but I read that it can be 5 years from when supervision was completed. meaning it wont be till 11-2016. Hopefully the 5 year count starts on the day he plead guilty with court supervision. And the problem isn't with the criminal side of this. Employers will not see it on the background check since it was just supervision. The problem is they WILL see it on the MVR for the CDL

 

luckily there was no criminal conviction of any kind. its the driving record however that matters. Thing is that I talked to many Polish guys that drive for predominantly polish companies that have a dui 2-3 years ago but still drive long distance somehow. oh well I guess time will tell. I know someone that will take him into a driving school for a few bucks. So at least hes paying next to nothing for the driving school. On that end there isn't much to loose from a financial stand point so its worth a shot
