¶1Derwin Miles Taylor appeals from the denial of his motion for a new trial following his conviction on a single count of trafficking in marijuana, for which he was sentenced to 30 years imprisonment. On appeal, as in his motion for a new trial, he contends that the trial court erred in pretrial proceedings by denying his motion to suppress evidence obtained from a search of his vehicle during a traffic stop. Because we agree with the trial court that the law enforcement officer who stopped Taylor articulated a reasonable suspicion of criminal activity sufficient to allow him to detain Taylor for further investigation, we affirm the trial court’s denial of Taylor’s motion to suppress and his motion for a new trial.
¶2On appeal from a denial of a motion to suppress, “this Court must construe the evidence most favorably to uphold the ruling of the trial court.” Jones v. State, 253 Ga. App. 870, 870 (560 SE2d 749) (2002) (citation omitted). The “trial court’s application of law to facts which are undisputed is subject to de novo review.” Id. (citation omitted).
¶3Here, the relevant evidence consisted entirely of testimony at a hearing on Taylor’s motion to suppress by the deputy who performed the search on Taylor’s vehicle. The deputy was a canine handler with the county’s uniform patrol division. He testified that he stopped *815Taylor while driving on Interstate 75 for failure to maintain lane and for having window tint that was too dark. As Taylor was providing the deputy with his license and registration, the deputy observed in Taylor’s car numerous air fresheners and packages that were releasing an “overwhelming” odor of air freshener. The deputy also noticed Taylor’s hands shaking as he provided his license and registration, a reaction the deputy took as a sign of nervousness on Taylor’s part.
¶4Taylor exited his vehicle at the deputy’s request, and he stood outside the vehicle as the deputy wrote two traffic warnings for Taylor. The two had a prolonged discussion outside the vehicle in which Taylor answered a number of the deputy’s questions, including where he was coming from at the time of the traffic stop. Taylor told the deputy he had been in Atlanta visiting his uncle in the hospital but struggled to identify where he was hospitalized or why he was sick. The deputy also testified that, in the course of their discussion, Taylor gave conflicting statements about where he had stayed the night before, first telling him that he stayed in an apartment and later saying that he had stayed in a hotel.
¶5During a break in this conversation, the deputy stepped away for a moment to call for backup and then returned to speak to Taylor again.
¶6After Taylor refused to allow the deputy to search the vehicle, the deputy indicated to Taylor that he was going to bring over a K-9 dog with specialized narcotics training to sniff Taylor’s vehicle. As the deputy was walking to his patrol car to retrieve the dog, the dispatcher replied to the deputy confirming Taylor’s license and registration information. After collecting the dog from his patrol car, the deputy brought the dog to Taylor’s car to conduct a sniff of the vehicle. The dog provided a positive response to the sniff, and the deputy proceeded to search Taylor’s vehicle, whereupon he found a large suitcase in the trunk containing a significant quantity of marijuana.
¶7*816Taylor was arrested and charged with trafficking in marijuana. Before trial, Taylor moved to suppress all evidence seized from his vehicle by the deputy. The trial court denied the motion through a series of orders.
¶8Taylor argues that the deputy lacked a reasonable articulable suspicion of criminal activity sufficient to detain Taylor for a drug sniff of the vehicle after the purpose of the traffic stop had concluded. Absent such reasonable suspicion, the extension of an otherwise completed traffic stop in order to conduct a free-air search of a vehicle using a drug dog violates the Fourth Amendment’s protection against unreasonable searches and seizures. Rodriguez v. United States, _ U. S._ (135 SCt 1609, 1614, 191 LE2d 492) (2015). An officer who initiates a lawful traffic stop, however, can shift into a criminal investigation so long as the officer can articulate reasonable suspicion that criminal activity is occurring. See Rodriguez v. State, 295 Ga. 362, 369 (761 SE2d 19) (2014).
To satisfy this “reasonable suspicion” standard, the officer’s investigation must be justified by specific articulable facts sufficient to give rise to a reasonable suspicion of criminal conduct. Articulable suspicion requires a particularized and objective basis for suspecting that a citizen is involved in criminal activity. Although this suspicion need not meet the higher standard of probable cause, it must be more than a mere caprice or a hunch.
¶9State v. Whitt, 277 Ga. App. 49, 50 (625 SE2d 418) (2005) (citation and emphasis omitted).
To determine whether a reasonable articulable suspicion exists, courts must look to the totality of the circumstances. Based upon that whole picture the detaining officers must have a particularized and objective basis for suspecting the particular person stopped of criminal activity.
¶10State v. Thompson, 256 Ga.App. 188, 189-190 (569 SE2d 254) (2002) (citations and punctuation omitted). Ultimately, “[t]he State bears *817the burden of proving that the search of the car was lawful, and to carry this burden, the State must show that it was lawful to detain [the defendant] until the time the drug dog indicated the presence of drugs.” Dominguez v. State, 310 Ga. App. 370, 372 (714 SE2d 25) (2011) (citation omitted).
¶11Here, we agree with the trial court that the State has carried this burden, as the totality of circumstances encountered by the deputy at the scene allowed him to form the requisite level of suspicion necessary to convert the traffic stop into a broader criminal investigation. The trial court found that Taylor’s supposed nervousness was not a factor, on its own, that the deputy could consider in forming a reasonable suspicion of criminal activity, and we agree with that determination. See Barraco v. State, 244 Ga. App. 849, 852 (2) (b) (537 SE2d 114) (2000) (“[e]ven when other factors are present, nervous behavior of a person who has been stopped by an armed law enforcement officer is not an unusual response and is not necessarily strong evidence to support either reasonable suspicion or probable cause”). However, the trial court determined, and we agree, that the strong smell of air fresheners in the vehicle, Taylor’s vague and conflicting statements about his uncle’s illness and his own whereabouts the night before, and the location of the traffic stop along a stretch of Interstate 75 that was known by the deputy to be a drug trafficking corridor were factors that allowed the deputy to form and articulate a reasonable suspicion of drug activity.
¶12Taylor suggests that this Court’s decision in State v. Thompson
¶13In this case, Taylor argues that it is “common knowledge” that Interstate 20 is “just as much a drug corridor” as Interstate 75 and that the outcome of this case should be identical to that in Thompson . However, in Thompson , even though the facts set forth in this Court’s opinion show that the stop occurred on Interstate 20, it does not appear that the officers in that case articulated the location of the stop as a basis for their suspicion or that the court considered evidence that the area was a known trafficking corridor. Thus, in Thompson , the officers were relying solely on their observation of the defendant’s nervousness and the smell of detergent and air freshener in forming their suspicion. See id. at 190.
¶14In this case, however, the trial court determined that the overwhelming smell of air fresheners, the location of the stop along the interstate, and, Taylor’s inconsistent statements to the deputy were all factors that, in totality, could allow the deputy to form the required suspicion. As this Court’s decisions in Wilson v. State
¶15We thus conclude that although Taylor’s conduct observed by the officer at the time of the stop in this case may have been “susceptible to an innocent explanation, ... it is also consistent with illegal activity” Giles, 284 Ga. App. at 4 (citations and punctuation omitted). Accordingly, we agree with the trial court that the totality of the circumstances encountered by the deputy — namely, the smell of air fresheners, the location of the stop along what the officer knew to be a trafficking corridor, and the vague and conflicting stories offered by Taylor — allowed him to form the reasonable suspicion necessary to commence a criminal investigation. We therefore affirm the trial court’s denial of Taylor’s motion to suppress, and, in turn, its denial of his motion for a new trial.
¶16Judgment affirmed.
¶17 The deputy testified that he called for backup at this point in his encounter with Taylor because he noted so many “red flags” and believed that “more than just a normal routine traffic stop” was unfolding. The deputy further explained that he called for backup before seeking Taylor’s consent to search the vehicle out of concern for safety.
¶18 After reconsideration and a second hearing, the trial court again denied the motion to suppress. The trial judge filed a certificate of immediate review, but this Court denied Taylor’s petition for leave to file an interlocutory appeal. See Case No. A16I0019.

¶23Wilson, 306 Ga. App. at 289 (noting conflicts in statements made by vehicle’s occupants and defendant’s inability to identify the location he had just visited as factors the officer could consider in forming suspicion).
¶24 This case aptly illustrates this point. The video of the traffic stop captured by the dashboard camera on the deputy’s patrol car shows that, upon discovering a large package *819containing marijuana in Taylor’s car, the deputy gleefully exclaimed to Taylor, “this ain’t my first rodeo!” While an officer’s training and experience alone do not provide an officer carte blanche to initiate drug investigations, our cases do credit an officer’s training and experience as factors to be considered when evaluating otherwise lawful actions that an officer may interpret as “red flags” during a traffic stop. See, e.g., Wilson, 306 Ga. App. at 289 (officer’s “knowledge of drug trafficking in the area” was factor in upholding determination of reasonable suspicion); Giles v. State, 284 Ga. App. 1, 4 (642 SE2d 921) (2007) (noting arresting officer’s “extensive interdiction training and knowledge of drug smuggling patterns”); State v. Causey, 246 Ga. App. 829, 833 (1) (b) (540 SE2d 696) (2000) (noting that officers’ “first-hand experience” with similar offenses informs reasonable conclusions that criminal activity is taking place).
