Silas V. Cerino was convicted of possession of methamphetamine. On appeal, Cerino contends that the district court erred in denying his motion to suppress evidence that police obtained as a result of an investigative stop. We reverse and remand.

BACKGROUND
Rupert police officers received an anonymous tip stating that a white Nissan pickup bearing IB (Bannock County) license plates was transporting illegal drugs between eastern Idaho and Ruрert. The rest of the license number was not given. The tipster also identified a specific residence in Rupert where the vehicle would stop in the cоurse of the drug transport. Detective Reed of the Rupert Police Department, while conducting surveillance of the identified house, saw a vehiclе matching the tipster’s description parked at the residence. Detective Reed radioed an inquiry on the registration of the vehicle. Dispatch responded that there were two registered owners — Silas Cerino and Robin Cerino. Reed did not know, and had never heard of, either registered owner. Reed later saw a man leave the Rupert residence and drive away in the white pickup. Reed then requested a driver’s license check on the male rеgistered owner and was informed that Silas Cerino did not have an Idaho driver’s license. Suspecting that the male driving the vehicle was Cerino, Reed requested another officer to stop the driver for operating a vehicle without a valid license. After the vehicle was stopped, it was discovered that the driver was in fact Silas Cerino and he was then arrested for driving without a license. 1 In a subsequent inventory search of Cerino’s vehicle, officers discovered a plastic baggie containing crystal methamphetamine and a prescription bottle with methamphetamine residue.
Cerino was charged with possеssion of methamphetamine, Idaho Code § 37-2732(c)(1). He pleaded not guilty and filed a motion to suppress the evidence gathered subsequent to the stop, contending that the police officers lacked reasonable suspicion to conduct an investigative stop. The district court denied the motion, holding that the stop was constitutionally reasonable based upon Detective Reed’s suspicion that Cerino was operating a vehicle without а valid driver’s license. Following the denial of his suppression motion, Cerino conditionally pleaded guilty, reserving his right to appeal the denial of the motiоn. Cerino received a suspended seven-year sentence with a two-year determinate term and was placed on probation.

ANALYSIS
The Fourth Amendment to the United States Constitution guarantees every citizen the right to be free from unreasonable searches and seizures. Its purpose is “to impose a standard of ‘reasonableness’ upon the exercise of discretion by government officials, including law enforcement agents, in order to ‘safeguard the privacy and security of individuals against arbitrary invasions.’”
Delaware v. Prouse,
The constitutionality of particular lаw enforcement conduct “is judged by balancing its intrusion on the individual’s
*738
Fourth Amendment interests against its promotion of legitimate governmental interests.”

In the prеsent case, the State concedes that the anonymous tip did not bear sufficient indicia of reliability to create reasonable suspicion.
See, e.g., Florida v. J.L.,
First, as to Cerino’s driving status, the detective knew only that Cerino had not obtained an Idaho driver’s license; he had no information as tо whether Cerino held a driver’s license from another jurisdiction. More importantly, because Detective Reed had never previously seen Cerino аnd had received no physical description of him, nothing but the driver’s gender “matched” the officer’s information about Cerino. In these circumstances there was little basis to infer that the male registrant was driving; it was as plausible and perhaps more likely, that the driver was someone else. It is not unlawful for a person to drive a vehicle that is registered to an unlicensed owner, nor for the unlicensed owner to allow another to drive his vehicle. We conclude that the mere observation of a vehicle being driven by someone of the same gender as the unlicensed owner is insufficient to give rise to a reasonable suspicion of unlawful activity. A contrary holding would endorse the sort of arbitrary invasions of personal liberty and privacy that the Fourth Amendment is designed to hold in check. Officers could run owner registration and driver’s license cheeks for any vehicle they see in operation, seeking an owner without an Idaho license and a driver of the same gender, and would be authorized to stop any vehicle meeting these criteria. In our judgment, the Fourth Amendment safeguard rеquires more particularized suspicion to justify the “constitutionally cognizable intrusion” of stopping a motorist.
We recognize that in addition to knowing that the male owner of the vehicle lacked an Idaho license, Detective Reed also knew about the anonymous tip indicating that a similar vehicle was being used to transport illegal drugs. However, the tipster’s information did not bolster the likelihood that Cerino was the vehicle’s driver at the time of the stop, nor did thе information that Cerino was unlicensed tend to corroborate the anonymous tip. These two unrelated pieces of *739 information do not add up to reasonable suspicion.
We hold that the information known to Detective Reed at the time he ordered the stop of Cerino’s vehicle was insufficient to create reasonable suspicion that the vehicle or its driver were involved in unlawful activity. Accordingly, the order of the district court denying Cerino’s motion to suppress evidence is reversed, and the ease is remanded.
Notes
. The officer's authority to arrest Cerino for driving without a license, rather than issue a citation, is not questioned in this appeal.
