If you were cited for driving on a suspended license and wish to contest the citation, you need to remember that the prosecution bears the burden of proving the crime by "beyond a reasonable doubt" which will require the citing officer to attend the hearing in person.You have the right to cross examine the citing officer as well as to call witnesses on your behalf such as your girlfriend who was supposedly driving.You need to present a clear defense that you were not the person driving. Whether or not the trier of fact believes the police officer and the prosecution meets its burden of proof as to the charge against you remains to be seen since you have yet to have your trial.Good luck.
