We consider the constitutionality of a decision to impound a vehicle based on a community-caretaking justification. Such impoundments have been the topic of substantial debate and disagreement among our sibling circuits. In this case, police, for reasons not articulated in any policy, impounded a vehicle lawfully parked in a private lot after arresting its driver as she exited a store. They made no meaningful attempt to allow the driver, her companion, or the owner of the parking lot to make alternative arrangements. The district court granted a motion to suppress contraband found in the vehicle, and the United States filed an interlocutory appeal. After surveying Supreme Court and Tenth

Police officers in Aurora, Colorado were looking for Beverly Sanders on an outstanding warrant for failure to comply with probation conditions related to a prior controlled substance conviction. They found a Mitsubishi Eclipse that they believed belonged to Sanders parked in the lot of a Goodwill store. Sanders and a companion, Ian Hussey, exited the store, walked to the car, and were ordered to the ground by police. Sanders was immediately arrested for the outstanding warrant. Although Sanders gave permission for a third party to come pick up the vehicle, the police did not ask Sanders whether she knew anyone who could remove the car.
Hussey was released after police cleared him of outstanding warrants, but he remained on the scene, inquiring about what would happen to the car and offering to contact someone to pick up the car, although he did not identify anyone specifically. Police were unwilling to release the car to Hussey because he did not have a valid driver’s license. Approximately thirty seconds after Hussey was released, he was arrested when police found a baggie containing what appeared to be heroin near the location where he had been ordered to the ground during Sanders’ arrest.
Aurora police use an impoundment form that contains a liability release, under which an arrestee may agree to release police from liability for any damage to or theft of their car, and also to leave their car in place for no more than 24 hours. Sanders was not asked by any officer to sign that waiver. The police nevertheless decided to impound the Eclipse out of fear that its contents, attractive exterior, and after-market accessories would lead to a break-in, particularly because it was located in a high-crime area after dark. One of the officers testified that she believed that the car would be broken into within two ' hours if left in the parking lot. Aurora has an ordinance listing 21 separate grounds for impounding a vehicle, but the vehicle being located in a high-crime area or being a likely target for a crime are not among them.
Having decided to impound the Eclipse, the police conducted an inventory search before removing it from the lot. They discovered what they believed to be drugs, including methamphetamine and Ecstasy, and related paraphernalia. Sanders was indicted for possessing controlled substances with intent to distribute. She moved to suppress the fruits of the inventory search. The district court granted the motion because the police impounded the car for reasons not listed in Aurora’s impound policy. The government filed a timely interlocutory appeal.

We review de novo the legal question of whether a seizure is reasonable
A
The Supreme Court has addressed the constitutionality of community-caretaking impoundments in several cases. In South Dakota v. Opperman,
In the interests of public safety and as part of what the Court has called eom-munity caretaking functions, automobiles are frequently taken into police custody. Vehicle accidents present one such occasion. To permit the uninterrupted flow of traffic and in some circumstances to preserve evidence, disabled or damaged vehicles will often be removed from the highways or streets at the behest of police engaged solely in caretaking and trafSc-control activities. Police will also frequently remove and impound automobiles which violate parking ordinances and which thereby jeopardize both the public safety and the efficient movement of vehicular traffic. The authority of police to seize and remove from the streets vehicles impeding traffic or threatening public safety and convenience is beyond challenge.
Id. at 368-69,
Later, in Colorado v. Bertine,
Opperman and Bertine establish two different, but not inconsistent, rules regarding when impoundments are constitutional. The Opperman decision establishes that some warrantless im-poundments are constitutional: namely, those required by the community-care-taking functions of protecting public safety and promoting the efficient movement of traffic. Meanwhile, the Bertine decision establishes that other warrantless impoundments are unconstitutional: namely, those justified by police discretion that is either exercised as a pretext for criminal investigation or not exercised according to standardized criteria. However, Bertine and Opperman leave a large number of impoundments open to case-based reasonableness judgments: namely, those carried out pursuant to standardized criteria but not justified by the public safety and traffic control goals of Opperman. Assessing when such impoundments are constitutional has generated controversy both within our circuit and among other circuits.
B
We have addressed the legality of im-poundments on several occasions. Most recently, we held that “[gjranting police discretion over whether to impound and inventory a vehicle is permissible so long as officers exercise that discretion according to standardized criteria, and not in bad faith or for the sole purpose of investigation.” United States v. Taylor,
In United States v. Pappas,
A divided panel later considered a similar impoundment, but distinguished Pap-pas on the basis that Pappas’ associates had ample opportunities to retrieve his vehicle. United States v. Kornegay,
First, the agents here arrested a person whose real identity they did not know. Second, they did not know where helived. Indeed, they had been unable to identify him as coming from ... the place of residence he had listed with the auction company. Third, he was alone, and there was no friend, relative or companion who could be asked to care for the car. Fourth, they did not know where the vehicle was from. Fifth, the vehicle was not parked on his property, and the agents had every reason to believe that he would not be returning anytime soon to the auction company’s lot to care for it himself. Sixth, to have left the vehicle in the auction company’s parking lot — a lot open to the public— could have subjected it to vandalism or theft. The fact that the vehicle was legally parked in a parking lot does not, in and of itself, require the finding that impoundment was unnecessary.
Id. at 716. Judge McKay dissented, contending that the impoundment was both unreasonable and indistinguishable from the unlawful impoundment in Pappas:
In this case, the defendant had parked his car in a lawful place and left it there to go inside to do business. It was there that he was arrested. I believe it goes well beyond any established Supreme Court precedent and beyond logic to ratify an “inventory” search based on the assertion that securing this vehicle under the circumstances was either necessary or permissible. The suggestion of some police duty to the car here argues too much. It was not unlawfully parked. It was not a traffic hazard. They had not stopped him while driving or otherwise removed him from his car. His arrest was no more associated with this car than the arrest of a shoplifter would be associated with his or her car. The facts of this case make what one often suspects is pretext, patent.
Id. at 719 (McKay, J., dissenting).
In Ibarra, a driver was cited for having an expired license.
Lastly, in United States v. Maher,
Our cases reaffirm the holdings of Ber-tine and Opperman. In Taylor, we recognized, citing Bertine, that standardized criteria generally must confíne officer discretion to impound vehicles.
C
Other circuits have also grappled with the constitutionality of community-caretak-ing impoundments. The Eighth Circuit holds that such impoundments must be regulated by “[s]ome degree of standardized criteria or established routine.” United States v. Petty,
In United States v. Duguay,
The D.C. Circuit follows a subtly different approach. It holds that “if a standard impoundment procedure exists, a police officer’s failure to adhere thereto is unreasonable and violates the Fourth Amendment.” United States v. Proctor,
The Ninth Circuit holds that decisions to impound vehicles cannot be left to unfettered officer discretion. Miranda v. City of Cornelius,
The First, Third, and Fifth Circuits take a different approach. These circuits decline to ever look to the presence of standardized procedures, and instead conclude that reasonableness is the only test. See United States v. McKinnon,
There is a clear divide between the First, Third, and Fifth Circuits, which never consider whether an impoundment follows standardized procedures, and the Seventh, Eighth, Ninth, and D.C. Circuits. There are also subtle differences between the tests applied by the latter circuits. For instance, the D.C. Circuit’s approach requires standardized procedures to be followed only if they exist, creating a perverse incentive to avoid the adoption of standardized procedures. See Proctor,
D
We hold that impoundment of a vehicle located on private property that is neither obstructing traffic nor creating an imminent threat to public safety is constitutional only if justified by both a standardized policy and a reasonable, non-pre-textual community-caretaking rationale.
Our holding, like that of a majority of circuits, recognizes that Bertine makes the
Our requirement that standardized criteria guide impoundments on private property ensures that police discretion to impound vehicles is cabined rather than uncontrolled. Cf. Miranda,
Yet Opperman establishes that if a vehicle is obstructing or impeding traffic on public property, it can be impounded regardless of whether the impoundment is guided by standardized procedures. See
Moreover, because our holding requires all community-caretaking impound-ments to be supported by a reasonable, non-pretextual justification, it guards against arbitrary impoundments. See Taylor,
Ascertaining whether an impoundment is justified by a reasonable and legitimate, non-pretextual community-caretaking rationale is not an easy task. We note that courts have considered the following nonexclusive list of factors: (1) whether the vehicle is on public or private property; (2) if on private property, whether the property owner has been consulted; (3) whether an alternative to impoundment exists (especially another person capable of driving the vehicle); (4) whether the vehicle is implicated in a crime; and (5) whether the vehicle’s owner and/or driver have consented to the impoundment.
E
Applying the rule elucidated above to the facts of this case, we conclude that the impoundment was impermissible because the officers were not guided by standardized criteria. The vehicle was legally parked in a private lot, and there is no evidence that it was either impeding traffic or posing a risk to public safety. Yet the record reveals that although Aurora’s municipal code explicitly authorizes the im-poundment of vehicles from public property in a list of enumerated circumstances, it nowhere mentions impoundment from private lots. It is therefore reasonable to infer that the code does not authorize, and moreover proscribes, the impoundment of vehicles from private lots. Cf. Youren v. Tintic Sch. Dist.,
Aurora policy allowed police to offer Sanders the options of releasing them from potential liability if the vehicle was left in the lot or of having the vehicle towed by a private company. But there is no evidence that the police offered Sanders either of these options. Nor did they explain why they failed to mention these options. Unlike in Maher, the vehicle was not itself evidence of the crime for which Sanders was initially arrested, making the officers’ failure to offer her these options relevant to our inquiry. Cf.
Lastly, unlike the policy upheld by the Bertine Court, which establishes “several conditions that must be met” before alternatives to impoundment are pursued,

The district court’s grant of the motion to suppress is AFFIRMED.
