Opinion for the court filed by Circuit Judge HENDERSON.
A jury found appellant Douglas Myron Proctor guilty of unlawful possession of a firearm and ammunition by a felon in violation of 18 U.S.C. § 922(g)(1). He was sentenced to 120 months’ imprisonment and five years’ supervised release. Proctor now appeals the district court’s denial of his motion to suppress evidence obtained during an inventory search of his vehicle following his arrest for moving violations on the ground that the arresting officers failed to follow standard police procedures when they impounded his car and subsequently retrieved a weapon from *1350 a trash bag found in the trunk. For the reasons set forth below, we conclude that the district court erred in denying the motion to suppress and reverse the district court’s judgment.
I.
At approximately 1:35 a.m. on September 8, 2004, Metropolitan Police Department (MPD) Officer Jody Shegan, and his partner, Officer Martin Nassar, while parked near Spingarn High School at the corner of 26th Street and Benning Road, Northeast, in Washington, D.C., received a radio call informing them that a maroon 1989 Mercury Grand Marquis traveling westbound on Benning Road had failed to stop at a red light. After the vehicle turned onto 26th Street and passed by Officers Shegan and Nassar, they followed it for a short distance before noticing that it had tinted windows. The officers initiated a traffic stop “[ajlmost immediately.” Tr. 11/23/04 at 7-8.
Proctor, the driver and sole occupant, produced his license and registration to Officer Nassar. At that time, Nassar noticed the odor of alcohol on Proctor’s breath. As he returned to the squad car to check the license and registration information, Nassar signaled to Shegan that Proctor had been drinking. Shegan then approached Proctor and initiated a conversation with him, during which Shegan too smelled alcohol and noticed that Proctor’s speech was slurred. When Shegan directed Proctor to step out of the vehicle, Proctor “swayed back and forth and used his vehicle as a leaning post so ... he wouldn’t fall down.” Id. at 9. Because Proctor exhibited signs of intoxication, Shegan placed him under arrest for operating a vehicle while intoxicated (OWI) and driving under the influence (DUI). 1
After Proctor’s arrest and while he remained at the scene, the officers conducted an inventory search of the vehicle. In the trunk, the officers recovered a .380 semiautomatic pistol from a “white trash bag,” Tr. 4/18/05 at 56, that also contained clothes and Proctor’s cell phone bill. From the front passenger seat, the officers recovered another plastic bag containing personal documents with Proctor’s name. After waiving his Miranda rights, Proctor informed the police that the bag belonged to him but the gun did not. In an indictment filed September 23, 2004, Proctor was charged with unlawful possession of a firearm and ammunition by a felon. On October 20, 2004, he filed a motion to suppress, challenging, inter alia, the physical evidence recovered during the inventory search. • '
At the November 23, 2004 suppression hearing, Officer Shegan, the hearing’s only witness, testified that the MPD standard procedure required the officers to impound Proctor’s vehicle after his arrest. Shegan, who had been a police officer for twenty years and a member of the MPD for three years, declared. that he did not “believe [he] had a choice” in impounding the vehicle, Tr. 11/23/04 at 38, because Proctor was not the owner and no one else was present to take custody of it, id. at 38, 24. Shegan further explained that the officers did not attempt to contact the owner to retrieve the vehicle because they “weren’t going to wait that long” and that they did not consider parking the car nearby because the police were “still responsible for the vehicle if it [was] parked.” Id. at 38. Pursuant to the MPD’s “new procedure” (She-gan’s term) for any vehicle not held as evidence or for civil forfeiture, id. at 25, Shegan testified that he requested the dis *1351 patch of a “ROC crane” — a crane operated by a private towing company which, by contract with the MPD, conducts towing operations for each Regional Operations Command — to remove the vehicle to a private impoundment lot instead of to the regional MPD station or the MPD im-poundment lot, id. at 24-25. 2
Shegan also testified that the MPD procedure required the officers to search “[t]he entire vehicle,” id. at 26, before removal “[t]o reduce liability on the police department and to preserve any property that the owner of the vehicle or the occupants of the vehicle may have,” id. at 25. He explained that
[t]he old policy was if a vehicle is taken to Metropolitan Police Department under the[ ] same circumstances [as here], the passenger compartment of the vehicle would be inventoried on the scene; and then within a certain amount of time after that, 24, 48 hours after that, then the entire vehicle, if the owner didn’t come and pick it up, the entire vehicle would be inventoried.... That policy is no longer in existence.
Id. at 26-27. According to Shegan, the current search policy went into effect when “Metropolitan Police Department didn’t have the room to store these vehicles.” Id. at 27.
In response to Shegan’s testimony, Proctor introduced into evidence a copy of MPD General Order 602.1 which sets forth MPD impoundment and inventory search procedure. General Order 602.1, Automobile Searches and Inventories (May 26, 1972) (GO 602.1), reprinted in Appendix for Appellant (AA) at 32. Part I.B.3, entitled “Prisoner’s Property,” provides, “When a person is arrested in an automobile which he owns or has been authorized to use and the vehicle cannot be classified [as evidence or for civil forfeiture], that vehicle shall be classified as prisoner’s property.” Id. at 42. Subpart (a) of Part I.B.3 provides that a vehicle “classified as prisoner’s property shall be disposed of in any lawful manner in which the person arrested directs. In any case where a prisoner requests that his vehicle be lawfully parked on a public street, he shall be required to indicate his request in writing.” Id. Subpart (b) provides:
If a vehicle classified as prisoner’s property is disposed of so that it is not taken to a police facility, it shall not be inventoried in any way. If it is necessary to take such a vehicle into police custody, the vehicle shall be taken to a police facility or to a location in front of or near a police facility. Immediately upon arrival at the police facility the arresting officer shall remove from the passenger compartment of the vehicle any personal property which can easily be seen from outside the vehicle and which reasonably has a value in excess of $25.... No other inventory or search of the vehicle shall be made at this time.
Id. at 43 (emphases added). And subpart (c) states:
If a person authorized by the prisoner or the prisoner himself, upon his release, does not claim the vehicle within 24 hours of the time that the prisoner was arrested, a complete inventory of the contents of the automobile shall be made by the arresting officer or an officer designated by an official.
Id. Finally, Part I.B.6, entitled “Scope of Inventory,” provides:
Whenever an officer has a right to inventory a vehicle pursuant to this order, *1352 the officer shall examine the passenger compartment, the glove compartment, whether or not locked, and the trunk, whether or not locked.... Any container such as boxes or suitcases found within the vehicle shall be opened ....
Id. at 46-47.
While rioting “a conflict or something of a disparity” between Shegan’s testimony and GO 602.1 regarding the MPD’s' im-poundment and inventory search procedure, Tr. 11/23/04 at . 62, the district court denied Proctor’s suppression motion. The court explained that “it is clear ... through the testimony of [Officer Shegan] that th[e written] procedures have been changed and perhaps because of financial realities or whatever it appears that the city in the last several years has adopted different procedures.” Id. at 63. The court found the “new procedure” — that is, an inventory search of a vehicle classified as “prisoner’s property” whether or not the vehicle is removed to a police facility— “reasonable” and concluded,
I have listened to the testimony of the particular officer and decided, based on the way he has testified and to the content, he seems to be knowledgeable and he strikes me as being an honest police officer with no agenda with respect to this particular vehicle during the time span of the events, that I find nothing that would even remotely suggest a pre-textual search in this case as a way of getting inside the trunk of that car.
Id. at 64.
A three-day jury trial was held in April 2005. On April 20, 2005, the jury found Proctor guilty and he was sentenced on August 8, 2005 to 120 months’ imprisonment and five years’ supervised release. This appeal followed.
II.
The Fourth Amendment to the United States Constitution protects “[t]he right' of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” U.S. Const, amend. IV. “The touchstone of the Amendment is reasonableness.”
United States v. Askew,
Proctor argues that both the im-poundment and subsequent search of his vehicle violated the Fourth Amendment because the officers failed to follow the MPD’s standard impoundment and inventory search procedure detailed in GO 602.1. Although he does not dispute that adherence to
unwritten
standard police procedure can satisfy the Fourth Amendment, he contends that Shegan’s testimony
*1353
failed to establish that the “new” — and unwritten — MPD procedure had in fact modified GO 602.1. In analyzing Proctor’s Fourth Amendment challenge, we review the district court’s factual findings for clear error, giving “ ‘due weight to inferences drawn from those facts,’ ”
United States v. Goree,
A seizure — including by impoundment— conducted without a search warrant is
“per se
unreasonable under the Fourth Amendment — subject only to a few specifically established and well delineated exceptions.”
Minnesota v. Dickerson,
At least two of our sister circuits have held that the decision to impound must be made pursuant to a standard procedure.
See United States v. Petty,
“Virtually by definition, the need for police to function as community caretakers arises fortuitously, when unexpected *1354 circumstances present some transient hazard which must be dealt with on the spot. The police cannot sensibly be expected to have developed, in advance, standard protocols running the entire gamut of possible eventualities. Rather, they must be free to follow ‘sound police procedure,’ that is to choose freely among the available options, so long as the option chosen is within the universe of reasonable choices.”
Coccia,
We believe that if a standard im-poundment procedure exists, a police officer’s failure to adhere thereto is unreasonable and violates the Fourth Amendment.
Cf. United States v. Maple,
The officers’ impoundment decision led to an inventory search that also violated GO 602.1. As noted earlier, Shegan testified that due to a lack of impoundment space at MPD facilities, MPD’s “new procedure” necessitated that a ROC crane tow Proctor’s vehicle to a private impoundment lot rather than to an MPD facility. Id. at 24-25, 52-53. According to Shegan, the officers were thus required to search “[t]he entire vehicle” before it was towed, id. at 26, “[t]o reduce liability on the police department and to preserve any property that the owner of the vehicle or the occupants of the vehicle may have,” id. at 25. GO 602.1, however, expressly prohibits an inventory search of a vehicle not taken to an MPD impoundment lot. GO 602.1, AA at 43 (“If a vehicle classified as prisoner’s property is disposed of so that it is not taken to a police facility, it shall not be inventoried in any way.”). 5
The Fourth Amendment requires, again, that an inventory search be reasonable and, if a standard procedure for conducting an inventory search is in effect, it must be followed.
See Maple,
Because the officers failed to follow the MPD standard procedure, the impoundment of Proctor’s vehicle was unreasonable and thus violated the Fourth Amendment. Likewise, “if the seizure of the car was unconstitutional, the materials later recovered during the inventory search [are] excluded.”
Coccia,
For the foregoing reasons, the judgment of the district court is reversed.
So ordered.
Notes
. Proctor ultimately received traffic citations for running a red light and having tinted windows in addition to the OWI and DUI charges. Tr. 11/23/04 at 27.
. Shegan testified that the “new procedure” was developed in response to the lack of MPD impoundment space. Tr. 11/23/04 at 25.
. In
United States v. Reese,
. Because Proctor was charged with OWI and DUI, we believe the officers were also required to follow the impoundment procedures set forth in the Comprehensive Anti-Drunk Driving Amendments Act of 1991, D.C.Code § 50-2201.05(c-l) (Anti-Drunk Driving Act or Act). Indeed, both parties agreed that the Act rendered GO 602. l’s impoundment procedures obsolete as applied to DUI and OWI arrests. See Appellee’s Br. at 39 ("The Act rendered Part I.B.3(a) of General Order 602.1 obsolete as applied to DUI and OWI arrests.”); Reply Br. at 9 ("To the extent the Act is more restrictive than the General Order in limiting the options to impoundment of vehicles relating to DUI or OWI arrests, the statute trumps the General Order.”). The Act requires that, before impounding the vehicle, the officer allow the OWI or DUI arrestee to authorize the officer to release the vehicle to a licensed — and capable — driver who can take possession of it within a reasonable amount of time. See D.C.Code § 50-2201.05(c-l)(2)(C) ("The officer shall not cause the vehicle to be impounded if ... (C) [t]he arrested person authorizes the officer to release the vehicle " to a licensed individual not at the scene of the arrest who is physically capable of removing the vehicle in "a reasonable period of time.”) (emphasis added). At oral argument, the Government maintained that the burden is on the arrestee in the first instance to request that the vehicle be released to another. But to require an allegedly intoxicated driver to understand that he can avoid impoundment by authorizing the officer to allow another driver to remove the vehicle — without being so advised by the officer — is unrealistic if not unreasonable. If no licensed — and capable— driver can take possession of the vehicle within a reasonable amount of time, or if the arrestee is incapable of making the request, the Anti-Drunk Driving Act requires the officer to impound the vehicle. Id.
. Had the vehicle been towed to an MPD facility, the arresting officer would have been required "[¡immediately upon arrival” to remove from the passenger compartment of the vehicle any personal property "easily ... seen from outside the vehicle” and "reasonably ha[ving] a value in excess of $25.” GO 602.1, AA at 43. No further search of the vehicle is permitted unless “a person authorized by the prisoner or the prisoner himself ... [fails to] claim the vehicle within 24 hours of the time that the prisoner was arrested.” Id. In that case, an officer is required to make "a complete inventory of the contents of the automobile.” Id.
. In fact, MPD Special Order (SO) 03-14, entitled "Implementation of Centralized Towing Program,” a copy of which Proctor submitted pursuant to Federal Rule of Appellate Procedure 280, indicates that GO 602.1 remains in effect. SO 03-14 provides, "Except as may be modified by the provisions of this Special Order, the applicable provisions of the following directives shall continue to be followed: ... 4. General Order SPT — 602.1 (Automobile Searches and Inventories).” SO 03-14, Implementation of Centralized Towing Program, at 4 (June 15, 2003). SO 03-14 did not modify GO 602.1.
