[¶ 1.] Edward De La Rosa and Lane Stocker were arrested and charged with Possession of a Controlled Substance (SDCL 22-42-5) and Possession of Two Ounces or Less of Marijuana (SDCL 22-42-6). Both Defendants filed Motions to Suppress the drug evidence seized during a traffic stop on August 7, 2001. After an evidentiary hearing, the trial court entered its decision granting the motions to suppress. The State appeals claiming no constitutional violation occurs when a motorist is briefly detained for a few seconds beyond the conclusion of a traffic stop for a canine sniff of the vehicle’s exterior. We agree and reverse the trial court.
FACTS
[¶ 2.] During the Sturgis Motorcycle Rally, on August 7, 2001, De La Rosa was pulled over in Sturgis, South Dakota for failure to use his left turn signal. De La Rosa identified himself as being from Denver, Colorado. The arresting officer, Steve Marquardt, was an 18-year veteran of the South Dakota Highway Patrol on *685duty with his drug detection canine named Tess. After confirming that De La Rosa’s turn signal was in working order, Trooper Marquardt requested that De La Rosa accompany him to his patrol car. The trooper performed a radio check for warrants and a license check, which checks eventually came back clear, and he issued a warning citation for the signal violation.
[¶ 3.] Trooper Marquardt testified that once he returned De La Rosa’s documents and issued the warning citation, the traffic stop was completed but that he did not inform De La Rosa that he was free to go. Rather, he had De La Rosa stand in front of the patrol car while he used Tess to perform a sniff test on De La Rosa’s truck. Before beginning the sniff test, Officer Marquardt approached the passenger side of the truck and requested that the passenger, Defendant Lane Stocker, exit the vehicle. She did so, and Tess began her work. Tess indicated that there were drugs in the passenger compartment of the truck. A search of Stocker’s purse revealed marijuana. A further search of Stocker’s travel bag in the back of the pickup revealed some peyote and more marijuana. Both Stocker and De La Rosa were arrested.
[¶4.] The State has conceded that at the time the sniff test was performed, De La Rosa’s traffic stop was completed and that Trooper Marquardt had no particularized suspicion that illegal drugs were in the vehicle. Thus, the sole question on appeal is whether there is a violation of the Fourth Amendment of the United States Constitution and Article IV § 11 of the South Dakota Constitution (collectively Fourth Amendment) when a motorist’s detention at a valid traffic stop is briefly extended for a canine sniff of the vehicle’s exterior, when the officer has a drug canine at his immediate disposal. Based on a totality of the circumstances, we hold that the facts of this case result in no constitutional violation. We reverse the circuit court’s grant of the Defendants’ motions to suppress the evidence seized.
STANDARD OF REVIEW
[¶ 5.] In reviewing a motion to suppress based on an alleged violation of a constitutional right, we utilize the de novo standard. State v. Rechtenbach, 2002 SD 96, ¶ 6, 650 N.W.2d 290, 292 (citing State v. Hodges, 2001 SD 93, ¶8, 631 N.W.2d 206, 209). Findings of fact are reviewed under the clearly erroneous standard. Hodges, 2001 SD 93, ¶ 8, 631 N.W.2d at 209. “Once the facts have been determined, however, the application of a legal standard to those facts is a question of law reviewed de novo.” State v. Himing, 1999 SD 53, ¶ 8, 592 N.W.2d 600, 603 (citing Spenner v. City of Sioux Falls, 1998 SD 56, ¶ 13, 580 N,W.2d 606, 610). The facts in this case are not disputed so our review is de novo.
[¶ 6.] DOES A CONSTITUTIONAL FOURTH AMENDMENT VIOLATION OCCUR WHEN A MOTORIST’S DETENTION AT A VALID TRAFFIC STOP IS BRIEFLY EXTENDED FOR A CANINE SNIFF OF THE VEHICLE’S EXTERIOR, WHERE THE OFFICER HAS THE DRUG CANINE AT HIS IMMEDIATE DISPOSAL.
[¶7.] The Fourth Amendment protects citizens from unreasonable searches and seizures by government officials. US Const, amend. IV. Police officers are generally required to have a warrant issued by a judicial officer based on probable cause in order to seize an individual of his or her property. Terry v. Ohio, 392 U.S. 1, 20, 88 S.Ct. 1868, 1879, 20 L.Ed.2d 889, 905 (1968) (additional citations omitted). However, in Terry, 392 U.S. at 23, 88 S.Ct. at 1881, 20 L.Ed.2d at *686906-7, the United States Supreme Court has recognized the need to allow police officers to safely and effectively perform their functions. The Terry line of cases establishes that when a person is subject to an “investigative detention” rather than a full-blown custodial arrest, the officer need only have reasonable suspicion for the detention rather than the probable cause typically required. Id. at 30, 88 S.Ct. at 1884-85. An investigatory stop satisfies the Fourth Amendment if the officer’s action is supported by reasonable suspicion to believe that criminal activity “may be afoot.” Terry, 392 U.S. at 30, 88 S.Ct. at 1884, 20 L.Ed.2d at 911.1
[¶ 8.] There is no dispute that Trooper Marquardt was within constitutional bounds when he initially stopped De La Rosa. State v. Vento, 1999 SD 158, ¶ 8, 604 N.W.2d 468, 470 (citing State v. Cuny, 534 N.W.2d 52, 53 (S.D.1995)) (holding that an officer must have “specific and articulable suspicion of a violation” for a traffic stop to be permissible). The State concedes, however, that at the time the sniff test was conducted on the exterior of De La Rosa’s vehicle, the initial traffic stop was complete, and Trooper Marquardt had no particularized suspicion there were illegal drugs in the Defendant’s vehicle.
[¶ 9.] The Fourth Amendment to the constitution only prohibits unreasonable “search and seizures.” When this “constitutional standard” of reasonableness is measured by the totality of the circumstances, “we should not be governed by artificial distinctions.” Currency, 182 F.3d at 649. The touchstone of Fourth Amendment constitutional analysis is “the reasonableness in all the circumstances of the particular governmental invasion of a citizen’s personal security.” Pennsylvania v. Mimms, 434 U.S. 106, 108-109, 98 S.Ct. 330, 332, 54 L.Ed.2d 331, 333 (1977) (quoting Terry, 392 U.S. at 19, 88 S.Ct. at 1878, 20 L.Ed.2d at 906); State v. Lamont, 2001 SD 92, ¶ 38, 631 N.W.2d 603, 616. Reasonableness depends “on a balance between the public interest and the individual’s right to personal security free from arbitrary interference by law officers.” Mimms, 434 U.S. at 109, 98 S.Ct. at 332, 54 L.Ed.2d at 333 (citations omitted). The public interest in the suppression of illegal drugs and their devastating effect on our citizens is obvious.
Few problems affecting the health and welfare of our population, particularly our young, cause greater concern than the escalating use of controlled substances ... [a]nd many drugs ... may be easily concealed. As a result, the *687obstacles to detection of illegal conduct may be unmatched in any other area of law enforcement.
United States v. Mendenhall, 446 U.S. 544, 561-62, 100 S.Ct. 1870, 1881, 64 L.Ed.2d 497 (1980). (Powell, J., concurring.)
[¶ 10.] There is no question the initial stop of the Defendant’s vehicle was valid based upon the Trooper’s eyewitness observation that a traffic violation had occurred. SDCL ch 32-26 (motor vehicle rules of the road). For purposes of analysis of the issue before us, this also satisfied the constitutional standard of reasonable suspicion for that stop. Vento, 1999 SD 158, ¶ 8, 604 N.W.2d at 470. From that point, the Defendants invite this Court to dissect the facts into two distinct events, those involving the normal checks of a driver’s license and proof of insurance and second, the use of the drug dog to sniff
around the exterior of the Defendant’s vehicle. The Defendants argue the dog sniffing of the vehicle is constitutionally unreasonable based on an analysis of lack of reasonable suspicion.2
[¶ 11.] The lack of reasonable suspicion, however, does not automatically equate with unconstitutional conduct on the part of the officer.3 Here, the officer had the dog at hand in his vehicle, and the Defendants concede the sniffing activity was of a short duration. Had there been no “hits,” the delay to the motorists would have been a matter of seconds. We cannot accept the premise that while the State’s interest in drug interdiction is compelling, a few seconds delay for non-entry sniffing the exterior of a vehicle by a dog already on the scene is constitutionally unreasonable.4
*688[¶ 12.] Our analysis is guided by a twofold test: [1] “whether the officer’s action was justified at its inception” and [2] “whether it was reasonably related in scope to the circumstances which justified the interference in the first place.” Terry, 392 U.S. at 19-20, 88 S.Ct. at 1879, 20 L.Ed.2d at 906. Concerning the disputed second prong, it is hardly constitutionally consistent to hold that what the officer did in first checking the Defendant’s papers and then doing the sniff test to be constitutionally impermissible, yet conclude in the alternative that Trooper Marquardt would have been constitutionally justified in the sniff test had he done it before the traffic stop was finished. Constitutional rights should be based upon reasonableness of the totality of the government intrusion, rather than a mere bright-line rule based solely upon a timing sequence. Either both must be constitutionally impermissible or both constitutionally permissible.
[¶ 13.] We conclude that the analysis of the Eighth Circuit Court of Appeals in Currency, 182 F.3d at 648, to be constitutionally persuasive. Instead of improperly attempting to separate the trooper’s actions into two distinct sequences, as previously noted, the correct measure of constitutional reasonableness is totality of the circumstances. Currency, 182 F.3d at 646 (citing Ohio v. Robinette, 519 U.S. 33, 117 S.Ct. 417, 421, 136 L.Ed.2d 347 (1996)). See also State v. Kenyon, 2002 SD 111, ¶15, 651 N.W.2d 269, 274 (citing United States v. Arvizu, 534 U.S. 266, 273, 122 S.Ct. 744, 750-51, 151 L.Ed.2d 740 (2002)) (citing United States v. Cortez, 449 U.S. 411, 417-18, 101 S.Ct. 690, 694-5, 66 L.Ed.2d 621, 628-9 (1981)).
[¶ 14.] The Currency Court further focused on the nature of the inspection as
that of a short duration and lack of direct invasion of the citizen’s vehicle and concluded:
[A] canine sniff of the exterior of personal property in a public location “is so limited both in the manner in which the information is obtained and in the content of the information revealed by the procedure” that it does not constitute a “search” within the meaning of the Fourth Amendment. United States v. Place, 462 U.S. 696, 707, 103 S.Ct. 2637, 77 L.Ed.2d 110 (1983)
[[Image here]]
When applied to the exterior of vehicles, the canine sniff is an investigative procedure uniquely suited to this purpose — it is so uninstrusive as not to be a search, it takes very little time, and it “discloses only the presence or absence of narcotics, a contraband item.” Place, 462 U.S. at 707, 103 S.Ct. at 2637. For these reasons, when a police officer makes a traffic stop and has at his immediate disposal the canine resources to employ this uniquely limited investigate procedure, it does not violate the Fourth Amendment to require that the offending motorist’s detention be momentarily extended for a canine sniff of the vehicle’s exterior.
Id. at 647-49. Moreover, the Eighth Circuit has continued to- follow this constitutional analysis and rationale. United States v. Linkous, 285 F.3d 716, 721 (8thCir.2002); United States v. Gregory, 302 F.3d 805, 810 (8thCir.2002) (“[w]e have held that a brief drug scan at the end of a traffic stop does not require reasonable suspicion.”). The basis is that “the officer did not need to have probable cause or even reasonable suspicion to support this scan because ‘a dog sniff of the exterior of *689a vehicle is not a search.’ ” Gregory, 302 F.3d at 810 (citations omitted).
[¶ 15.] Today’s opinion is consistent with our recent analysis in State v. Ballard, 2000 SD 134, 617 N.W.2d 837. As we specifically acknowledged in Ballard, “[w]hether a particular intrusion will fall into the Terry exception will be decided by balancing the ‘quality of the intrusion on the individual’s Fourth Amendment interests against the importance of the governmental interests alleged to justify the intrusion.’ ” Ballard, 2000 SD 134, ¶ 10, 617 N.W.2d at 840 (citing Place, 462 U.S. at 703, 103 S.Ct. at 2642, 77 L.Ed.2d at 118; Terry, 392 U.S. at 20, 88 S.Ct. at 1879, 20 L.Ed.2d at 905).
[¶ 16.] Unlike Ballard, however, the officer in this case did not complete the traffic stop and then objectively foreclose any further investigation by telling the motorists that they were free to leave. In Ballard we concluded:
This case presents a close question on when continued detention becomes unreasonable. However, we are concerned with the dubious message we send to law enforcement officers and the public if we validate a procedure allowing officers to falsely tell traffic offenders they are free to go, only for the purpose of eliciting their uncoerced agreement to search their automobiles.
2000 SD 134, ¶ 17, 617 N.W.2d at 842. Because our holding in Ballard was expressly limited to facts involving a detention which followed the completion of a traffic stop by the officer’s announcement to the motorists that he or she was free to leave, Ballard does not apply to a traffic stop like the one now before us.
[¶ 17.] The artificial bright-line test result advocated by the Defendants does not comport with constitutional principles of reasonableness based upon a totality of the circumstances. Instead, it would result in constitutional rights based upon an officer’s checklist or a mad dash by one officer and dog to the stopped vehicle while the other officer checks out the driver’s papers. Defendants, or any driver for that fact, would be no more inconvenienced or delayed by a dog sniff in this case than would they be by a roadblock check point for detecting illegal aliens (Martinez-Fuerte, 428 U.S. at 543, 96 S.Ct. at 3076, 49 L.Ed.2d at 1116), roadblock-type stops to verify driver’s licenses and vehicle registrations, (Delaware v. Prouse, 440 U.S. 648, 663, 99 S.Ct. 1391, 59 L.Ed.2d 660 (1979)) or a roadblock-type checkpoint for game during a hunting season (State v. Halverson, 277 N.W.2d 723, 725 (S.D.1979)).
[¶ 18.] For the above reasons, we reverse the circuit court and remand for further proceedings consistent with this opinion.
[¶ 19.] KONENKAMP, and ZINTER, Justices, concur. [¶ 20.] SABERS, Justice, and AMUNDSON, Retired Justice, dissent. [¶ 21.] MEIERHENRY, Justice, not having been a member of the Court at the time this action was submitted to the Court, did not participate.. A Terry analysis may be of limited assistance in the resolution of the Fourth Amendment issue now before us. As the Eighth Circuit Court of Appeals reasoned in United States v. $404,905 in U.S. Currency, 182 F.3d 643 (8thCir.1999), Terry stops are properly done where the officers detain persons with only reasonable suspicion that criminal activity is afoot. However, the Court concluded that a traffic stop is not investigative; it is a form of arrest based upon probable cause that a penal law has been violated, generally by a violation committed in the presence of the arresting officer. Id. at 648. The Court concluded:
Applying the reasoning of Berkemer v. McCarty, [468 U.S. 420, 104 S.Ct. 3138, 82 L.Ed.2d 317 (1984)] and Knowles v. Iowa, [525 U.S. 113, 119 S.Ct. 484, 142 L.Ed.2d 492 (1998)] to the issue of unreasonable detention during a traffic stop, we believe the Supreme Court would not closely examine the time it takes a traffic officer to complete the traffic stop itself, consistent with the discretion given arresting officers in other contexts. But once the officer decides to let a routine traffic offender depart with a ticket, a warning or an all clear — a point in time determined, like other Fourth Amendment inquiries, by objective indicia of an officer's intent — then the Fourth Amendment applies to limit any subsequent detention or search.
Id. at 648.
. Although the objective facts before Trooper Marquardt may not rise to Terry’s reasonable suspicion standard that illegal drugs were in the car, Marquardt’s decision to have Tess sniff the Defendant's vehicle was not based solely upon whim or caprice. Marquardt testified that as a veteran Trooper and based upon his prior experience, Denver Colorado was a major source for drugs at the Sturgis Motorcycle Rally." He was also aware there was an increased amount of drug usage at the Sturgis Rally.
. Other cases have recognized and upheld similar intrusions made in the absence of a particularized suspicion. See Hodges, 2001 SD 93, ¶ 17, 631 N.W.2d at 211 (officer had right to order passenger to remain in vehicle stopped for traffic violation, even though no reasonable suspicion existed as to passenger at the time); Mimms, 434 U.S. at 111, 98 S.Ct. at 333, 54 L.Ed.2d at 333 (1977) (officer may order driver out of vehicle during traffic stop); United States v. Martinez-Fuerte, 428 U.S. 543, 562, 96 S.Ct. 3074, 3085, 49 L.Ed.2d 1116 (1976) (suspicion less Border Patrol checkpoint for detecting illegal aliens was valid). As the Court in Martinez-Fuerte noted, while some quantum of individualized suspicion is usually a prerequisite to a constitutional search and seizure, "the Fourth Amendment imposes no irreducible requirement of such suspicion.” 428 U.S. at 561, 96 S.Ct. at 3084. In that case, the United States Supreme Court determined the government’s interest in detecting illegal aliens outweighed the motorists' privacy interests. The Court relied, in part, on the fact that "one's expectation of privacy in an automobile and of freedom in its operation are significantly different from the traditional expectation of privacy and freedom in one's residence." Id. (citations omitted). The Court held the stopping of vehicles and questioning of their occupants was minimally intrusive and could be done in the absence of individualized suspicion. Id.
.At oral argument there was a lengthy discussion between the State and Justices of this Court as to whether the State would attempt to expand today's holding into a justification for unlimited stops of motorists to search for drugs. Clearly, the stop of a motorist and lengthy detention while a drug dog is brought in from a substantial distance is not constitutionally reasonable. We limit our decision of today to the facts of this case and leave for the future whether other "what ifs” are constitutionally permissible under a totality of circumstances standard of constitutional review. Bright-line rules instead of a totality of circumstances-reasonableness standard are generally disfavored in Fourth Amendment analy*688sis. Lamont, 2001 SD 92, ¶40, 631 N.W.2d at 617 (citations omitted).
