*595 FACTS
[¶ 2.] On July 15, 1996, Rapid City Police Officer Kyle Akers stopped a vehicle driven by Misty Bradford (Bradford), in which Richards was a passenger. Officer Akers was requested by a police radio broadcast from Rapid City Police Detective Dale McCabe to stop the vehicle, but was not provided the reason for the request.
[¶ 3.] The events leading up tо the stop in question are as follows. Bradford had been under investigation for drug-related activities. On July 9, 1996, a confidential informant employed by the South Dakota Division of Criminal Investigation (DCI) made a controlled drug purchase from Bradford. The transaction took place in Bradford’s vehicle.
[¶4.] Investigators became suspicious of Bradford’s involvement in a larger drug conspiracy after observations obtained through surveillance conducted the next few dаys. On July 15,1996, Bradford was seen meeting with two persons who were known drug dealers at a Rapid City motel. After this observation, the vehicle containing the two known drug dealers was stopped. A search of the vehicle uncovered a large amount of cash, some of which the serial numbers could be traced back to the July 9, 1996, controlled purchase conducted by the informant. Ricardo Conrado, one of the occupants of the vehicle, was interviewеd by officers. Conra-do told the officers that he had distributed drugs to Bradford.
[¶ 5.] Later that same evening on July 15, 1996, DCI Agent Buszko and Detective McCabe observed Bradford driving the same vehicle in which the drug transaction had taken place. At the time of this observation, Buszko and McCabe were driving an unmarked police vehicle. Detective McCabe contacted law enforcement dispatch by radio and requested the assistance of a marked vehicle, equipped with sirens and lights, to make a traffic stop. 1 Officer Akers responded. Detective McCabe provided Officer Ak-ers with a description and location of the vehicle and requested Officer Akers stop the vehicle. MсCabe did not inform Officer Ak-ers of his reason for his request.
[¶ 6.] Officer Akers stopped the vehicle. Agent Buszko and Detective McCabe, along with other agents of the drug task force and a highway trooper, arrived shortly thereafter.
[¶ 7.] As а result of the traffic stop, Bradford’s passenger, Misty Richards was arrested. Richards was arrested for open container. Officers searched the vehicle incident to arrest and controlled substances were discovered.
. [¶ 8.] Richards was indicted March 12, 1997, on one count of possession of a controlled substance. The trial court granted Richards’ motion to suppress evidence seized as a result of the traffic stop. State appeаls, raising the following issue:
Whether the trial court improperly limited the doctrine of collective knowledge in concluding that the reasonable suspicion possessed by Agent Buszko and Detective McCabe was not transferred to Officer Ak-ers.
STANDARD OF REVIEW
[¶ 9.] This appeal concerns whether the circuit court applied the correct legal standard to the facts in this case. “Questions requiring application of a legal standard are reviewed as arе questions of law — de novo.”
Voeltz v. John Morrell & Co.,
DECISION
[¶ 10.] Whether the trial court improperly limited the doctrine of collective knowl *596 edge in concluding that the reasonable suspicion possessed by Agent Buszko and Detective McCabe was not transferred to Officer Akers.
[¶ 11.] The Fourth Amendment of the United States Constitution protects against unreasonable searches and seizures and is implicated when a vehicle is stopped.
Delaware v. Prouse,
[¶ 12.] At issue in this case is the stop of a vehicle by an officer in reliance on a request by another officer who indicated the description and loсation of vehicle, but did not communicate his reason for requesting the stop. The trial court reasoned because there was no evidence of any flyer, warrant, bulletin or any information given to Officer Akers to inform him what the оccupants were suspected of, or wanted for any crime, Officer Akers had no reasonable or articulable basis to make the stop. In addition, since Officer Akers was not working with the Drug Task Force investigating the vehicle or its occupants, the traffic stop could not be justified by any “collective knowledge” which may have been possessed by Drug Task Force, but not Officer Akers. The trial court concluded since Officer Akers had no articulable nor reasonable suspicion to make the stop, the stop violated Richards’ constitutional right against unreasonable search and seizure and any fruits of same must be suppressed.
Wong Sun v. United States,
[¶ 13.] State relies on
United States v. Hensley
as authority that the officer executing the stop need not possess reasonable suspicion as long as the officer issuing the request for the stop has the requisite reasonable suspicion to make a stop.
[¶ 14.] While
Hensley
is distinguishable from the present case, given the existence of a written flyer with information contained therein, the language from
Hensley
suggests the appropriate anаlysis is whether the requesting officer had the requisite reasonable suspicion or probable cause.
Hensley,
[¶ 15.] South Dakota has recоgnized the necessity of law enforcement relying upon each other for determinations of reasonable suspicion and probable cause through the collective knowledge doctrine.
See Krebs,
[¶ 16.] While this Court has not ruled whether information has to be relayed to stopping officer, similar facts were presented in
Czmowski,
[¶ 17.] A similar situation occurred in
United States v. Kapperman,
“That [the arresting officer who had not participated in earlier investigation] may not have known all of the facts already uncovered in the investigation does not render the ‘arrest’ unlawful. Whеn there is minimal communication between different officers, we look to the collective knowledge of the officers in determining probable cause. United States v. Astling,733 F.2d 1446 , 1460 (11th Cir.1984). Further, [arresting officer] was entitled to act on the strength of the radiо communication directing him to ‘stop the vehicle and secure the scene.’ See Whiteley,401 U.S. 560 , 568,91 S.Ct. 1031 , 1037,28 L.Ed.2d 306 (1971).”
Kapperman,
[¶ 18.] A review of case law indicates whether or not probable cause or reasonable suspicion exists is determined by considering the information possessed by the requesting officer. This Court has been cited to no authority establishing the rationale that a specific quantum of information justifying a stop must be relayed to the stopping officer before the stop is upheld.

Notes
. DCI Agent Buszko testified that it is common practice to request the assistance of a marked police unit to make traffic stops in such situations.
. Richards admits in her brief that had Detective McCabe stated to Officer Akers, "stop the vehicle because the driver is suspected in a drug crime," the stop would have been valid.
