In Maryland if first offenders follow a prescribed series of steps and do not reoffend in 5 years, the DUI doesn't show up anywhere. They truly give first offenders a break.
My son received first DUI in May and was following the criteria outlined- attending classes, interlock device on vehicle- but unfortunately he drove his sister's car while we were on vacation and got a second DUI in August. This time the penalties are much more severe but as he says (in rehab now) "it takes what it takes".
I did notice that after his first DUI his attitude was rather cavalier but after spending 3 days in the maximum security lockup after the 2nd one, I think the severity of the situation has set in.
Good luck to you and I hope this is as bad as it gets for you.
