I am guessing from your fact pattern that you did not have an attorney represent you at your hearing. That was a huge mistake, as I am sure you have learned. You need to hire a criminal defense lawyer. They may be able to get a new hearing and actually tell the Judge the truth about your situation.
If you received a charge of driving on a suspended license with knowledge, which is a criminal offense, you are subject to your probation being violated. Your maximum sentence would be 5 years in prison minus any credit you are entitled to. I would contact an attorney ASAP.
The citation goes to the Clerk of the Court and also goes to the State Attorney's Office. It usually takes a few weeks before a prosecutor will review the file and this will usually be in the intake department.
Your question is extremely confusing. When you say 'she' lied to detective, I am not sure if you are referring to your mother or your sister. Either way, if you are asserting that you are not guilty of this offense and that it was in fact your sister who did this, you would need to take your case to trial. If you can no longer afford your attorney or you can't afford to pay him or her for trial, you may be eligible for a Public Defender.
