¶ 1 The People petitioned for review of the court of appeals' judgment reversing Brown's drug-related conviction on the ground that his motion to suppress should have been
*817
granted.
See
People v. Brown
,
¶ 2 Because the record fails to demonstrate that seizure of the defendant's vehicle was justified as an еxercise of the police caretaking function or was otherwise reasonable within the meaning of the Fourth Amendment, regardless of local ordinances or police policies and procedures broad enough to grant the officers discretion to impound the vehicle of a driver merely summoned rather than arrested for driving with a suspended license, the judgment оf the court of appeals is affirmed.
I.
¶ 3 Carl A. Brown was charged with and convicted of possession with intent to distribute a schedule II controlled substance, stemming from the discovery of crack cocaine during an inventory search of his vehicle. He was sentenced to ten years in the custody of the Colorado Department of Corrections.
¶ 4 Prior to trial, he moved to suppress the contraband on the ground that the impoundment and inventory search of his vehicle violated the dictates of the Fourth Amendment. Following a hearing of the motion, at which the factual allegations of the stop, search, and arrest were largely undisputed, the district court entered its findings of fact and conclusions of law. As pertinent to the issue before this court, the district cоurt's findings and the uncontested testimony indicated the following.
¶ 5 Upon receiving an anonymous report of a suspicious person driving a gray BMW in the area, two Aurora police officers observed the defendant's gray BMW fail to stop at a stop sign, pulled him over, and discovered that he was driving on a suspended license. Although the officers decided to issue a summons and releasе him, pursuant to routine police procedure authorized by an Aurora ordinance, the officers nevertheless decided to impound his vehicle and, while waiting for the towing company, inventoried its contents, discovered a number of bags of crack cocaine, and thereafter arrested him. With regard to the search of the defendant's vehicle, the court concluded that under these circumstances, Aurora police policies and procedures granted the officers the discretion to conduct an inventory search, and for that reason, the search was not pretextual, even if the officers hoped to find evidence of a crime.
¶ 6 After rejecting the prosecution's assertion of waiver, the court of apрeals found that whether the department's inventory procedure had been followed or not, the officers lacked justification for taking the vehicle into government custody in the first place. Reasoning that nothing in the record indicated the defendant could not lawfully provide for the vehicle himself, and thereby prevent it from becoming a public hazard or subjecting the police to liability for the loss of it or its contents, the intermediate appellate court concluded that the public function exception to the probable cause and warrant requirements of the Fourth Amendment had not been met and that compliance with department policies alone did not constitute such an exception. In the absence of prоof that the seizure of the vehicle fell within an exception to the Fourth Amendment warrant requirement, the court found that the exclusionary rule required suppression of the discovered items.
¶ 7 The People petitioned for a writ of certiorari.
II.
¶ 8 It is now well-settled that the seizure of vehicles by the police for caretaking purposes, as well as an inventory of the contents of vehicles lawfully in government
*818
custody, can amount to reasonable searches and seizures within the meaning of the Fourth Amendment without regard for either probable cause or a warrant.
See
Colorado v. Bertine
,
¶ 9 Unlike the rationales for and limits of inventоry searches of private property lawfully in government custody, the circumstances under which vehicles may become subject to impoundment by the government, implicating subsequent inventory of their contents, without suspicion that they themselves are connected to a crime, has received relatively little attention by the Supreme Court. As early as
Cady v. Dombrowski
,
¶ 10 In
Colorado v. Bertine
, for the first and only time, the Court addressed a challenge to the inventory search of a defendant's vehicle on the basis of departmental regulations giving the seizing officers discretion to impound the vehicle in the first plаce.
See
Bertine
,
¶ 11 In rejecting Bertine's challenge to the policy granting police officers the discretion to choose whether to impound, the Court did not uphold the seizure simply because in exercising discretion, the officers complied with deрartment policy, but rather for the reason that the policy reasonably circumscribed the discretion of the individual officers by imposing sufficient limitations on their discretion to use the alternate procedure
*819
of parking and locking.
¶ 12 In a passage heavily relied on by the People, and paraphrased by both this court and the court of appeals on several occasions, we attributed to
Bertine
the proposition that in the absence of evidence showing that the police acted in bad faith or for the sole purpose of investigation, inventory searches conducted according to рolice department policies and procedures are generally considered reasonable.
See
Pineda v. People
,
¶ 13 Because arresting a person stopped while driving a motоr vehicle necessarily deprives him of the immediate custody and control of that vehicle, the question has not infrequently arisen under what circumstances the vehicle may be impounded and subjected to an inventory of its contents.
See, e.g.
,
United States v. Sanders
,
¶ 14 With regard to a drivеr who remains in possession and control of his vehicle, it is even more clear than the case of an arrested driver that justifying impoundment as an exercise of a community caretaking function, so as to fall within that exception to the probable cause and warrant requirements of the Fourth Amendment, will be dependent upon the particular circumstances of the seizure in addition to the standardized policy or procedure. In light of the driver's retained freedom of action, short of reason to believe that he will be unable to make arrangements sufficient to prevent the vehicle from "impeding traffic or threatening public safety and convenience,"
Opperman
,
¶ 15 The authority of police to act in furtherance of a community caretaking function does not originate from the same source as their authority to investigate criminal activity. Community caretaking is not concerned with potential criminal activity, but rather with administration of the risk to public safety threatened by the vehicle.
See
Miranda v. City of Cornelius
,
III.
¶ 16 At the suppression hearing, the prosecution offered no evidence to suggest that any of the factors or purposes for which a community caretaking exception has been recognized supported the impoundment оf the defendant's vehicle. There was no suggestion that the car was impeding traffic or threatening public safety and convenience where it was stopped, much less that it was inoperable or otherwise unable to be safely and legally removed by a licensed party, even if that had been the case. Quite the contrary, the prosecution relied entirely on the fact that the vehicle was impounded pursuant to departmental procedure, based on an Aurora ordinance granting police officers the discretion to impound a vehicle being driven by someone whose driver's license had been suspended. To the extent the testimony of the officer who ordered the impoundment reflected any reason other than pоlicy, it suggested *821 only that the defendant was not offered an option to have the car left at the scene or towed because he had already demonstrated that he would drive on a suspended license.
¶ 17 Similarly, before this court, the People rely expressly on the assertion that seizing a vehicle in compliance with policies or procedures permitting as much is sufficient to bring it within an exception to the probable cause and warrant requirements of the Fourth Amendment. Alternatively they assert that impoundment of the vehicle of someone driving on a suspended license necessarily falls within the purposes of police caretaking functions by preventing a presumptively unsafe driver from endangering the public. Because we hаve rejected both of these rationales and the People assert no other exception to the Fourth Amendment probable cause requirement, we must conclude that the impoundment of the defendant's vehicle in this case and, therefore, its subsequent inventory violated the Fourth Amendment prohibition against unreasonable searches and seizures.
IV.
¶ 18 Because thе record fails to demonstrate that seizure of the defendant's vehicle was justified as an exercise of the police caretaking function or was otherwise reasonable within the meaning of the Fourth Amendment, regardless of local ordinances or police policies and procedures broad enough to grant the officers discretion to impound the vehicle of a driver merely summoned rather than arrested for driving with a suspended license, the judgment of the court of appeals is affirmed.
