Statutes of limitations apply to the length of time after a criminal episode that you can still be charged for the offense. The citation means that you were charged in 2002. Contact the clerk of the court about how you might be able to receive or review the complaint.
You should be able to get a copy of the complaint prior to trial is you submit a timely motion for discovery. If the complaint was not filed within two years of the alleged violation, then the statute of limitations will have run and the State cannot charge you with the offense unless you agree to waive the statute of limitations.
