Hameed Adil Jones was convicted on charges of cocaine possession and improper lane change. On appeal, he argues that the trial court erred in denying his motion to suppress. Because the trial court was authorized to conclude that Jones was not illegally detained during his traffic stop, and also because the investigating officer had reasonable, articulable reasons for suspecting criminal activity when he briefly detained Jones, we affirm. On appeal from a denial of a motion to suppress, we construe the evidence in favor of the trial court’s ruling, and the trial court’s application of law to undisputed facts is subject to de novo review. Jones v. State , 253 Ga. App. 870 560 SE2d 749 2002. And “where there is evidence to support the decision of a trial judge on motion to suppress evidence, that decision will not be disturbed on appeal.” Citations and punctuation omitted. In the Interest of J.L.G. , 209 Ga. App. 565, 566 434 SE2d 126 1993. Viewed in this light, the undisputed evidence presented at the hearing on Jones’s motion shows that Officer Russell Rogers stopped the vehicle driven by Jones after observing it twice cross the yellow line to the left and then veer to the right, over the white fog line. Rogers activated his blue lights, and before Jones came to a complete stop he observed Jones reach over passenger’s seat with his right hand. According to Rogers, Jones placed his “right hand up under the passenger seat and proceeded as if he were stuffing something up under the seat.” Rogers stated that Jones appeared to be “forcibly pushing” his arm under the front passenger seat. He thought Jones might be hiding something.
After the vehicle stopped, Rogers approached Jones and explained the reasons he had made the traffic stop. He also asked “Jones why he placed his hand up under the seat” and requested permission to search the vehicle. Jones, who was acting nervous and “sweating profusely,” denied that he had reached under the seat and refused permission to search. Rogers returned to his patrol car and called for the local canine unit while he was checking Jones’s license.
