The fact that you hold an Alabama driver license and the incident occurred in Georgia means the final disposition of the case will be reported by the Georgia court to the Alabama Department of Public Safety for entry on your Alabama driver license. Unless you are "acquitted", the clerk of the court will send the court abstract to Alabama for entry on your Alabama driver license.
The state of Alabama does not by statute or by decisional law recognize the plea of nolo contendre. However, the state of Georgia does and that is a common plea in the state of Georgia. Under Alabama law, a plea of nolo contendre is the functional equivalent of a plea of guilty. See, Code of Alabama, 1975, section 32-5A-195(i) and see the case of Bell v. Department of Public Safety where the appeallate court held that an out of state plea of nolo contendre to a DUI (in Georgia) was the same for purposes of license sanction as an in-state plea of guilty.
If you wish to contest the case, you should seek the professional legal services of a Georgia attorney, and one who practices extensively in the area of traffic law and driver licensing.
