Life gets a bit off track sometimes, such as the time a police officer pulled you over in a traffic stop and you wound up facing DUI charges in court. You didn't think you had to worry about conviction because you'd only had a small amount of alcohol to drink that evening; however, you could tell things weren't going your way when the police officer said you failed the field sobriety test. You'd never been in trouble with the law before that day.
Since then, you've heard tell about a process called expungement. This is when the court agrees to erase a conviction from your criminal record; in fact, it can extract any details regarding the unfortunate incident. No one (although there may be a few exceptions) will ever again be able to view your drunk driving conviction in your file.
