Georgia Code Title 40. Motor Vehicles and Traffic § 40-6-376

(a) Any offense, except a violation of subsection (b) of Code Section 40-6-270 or a violation of Code Section 40-6-393, which is a violation of a provision of this chapter and of a local ordinance may, at the discretion of the local law enforcement officer or prosecutor, be charged as a violation of the state statute or of the local ordinance. A violation of subsection (b) of Code Section 40-6-270 or a violation of Code Section 40-6-393 shall be charged as a state violation.

(b) If the offense charged under an ordinance constitutes a violation of any provision of this chapter, the defendant may request transfer of the charge to the appropriate state tribunal. If the defendant so requests, the recorder or city judge, after conducting a commitment hearing in which probable cause for arrest is found, or upon obtaining a waiver of commitment hearing, shall summarily fix the defendant's bond and bind his case over to the appropriate state tribunal.

(c) No person tried in any court for a violation of this chapter or any ordinance adopted pursuant thereto shall thereafter be tried in any court for the same offense. A conviction for the violation of an ordinance adopted pursuant to this chapter shall be considered a prior conviction for all purposes under this chapter and under Chapter 13 of this title.

(d) No court, other than a court having jurisdiction to try a person charged with a violation of Code Section 40-6-393, shall have jurisdiction over any offense arising under the laws of this state or the ordinances of any political subdivision thereof, which offense arose out of the same conduct which led to said person's being charged with a violation of Code Section 40-6-393 and any judgment rendered by such court shall be null and void.
