I live in South Carolina, but got my DUI in North Carolina. My license was suspended for 1 year, paid the fines, and completed all alcohol classes. My attorney at the time said I may have to get the interlock system installed, but if I waited for 3 years to reinstate my license I wouldn't have to. I wanted a second opinion because her knowledge of the laws with me being from a different state was limited. I did not know this until after I hired her.
