, Circuit Judge . LeShawn Stanbridge appeals his conviction for possession of methamphetamine with intent to distribute, 21 U.S.C. § 841(a )(1). The drugs had been found in Stanbridge’s car after police in Quincy, Illinois, detained him on the ground that he committed a traffic offense by not signaling continuously for 100 fe et before pulling alongside the curb to park. That understanding of Illinois law was2 No. 15-2686

wrong, but the district court decided that the mistake was
reasonable and, for that reason, denied Stanbridge’s motion to suppress the drugs. We hold that the mistake of law was

not reasonable, and thus Stanbr idge’s motion to suppress should have been granted.

I. BA C KGROU ND

Stanbridge was walking to his car carrying a duffel bag when two Quincy police office rs passed by on patrol. Stanbridge hesitated and looked surprised when he saw the officers, so they circled the block and began shadowing him with the hope of catching him in a traffic violation. After driving just a short distance, Stanbridge activated his right turn signal, pulled to the side ofthe street, and parked parallel with the curb. Officer Stev e Bangert, who was driving, had not witnessed any traffic violation before Stanbridge pulled over, but his partner, O fficer Paul Hodges, later reported that Stanbridge had turned left at an intersection without signaling while being followed. Unaware of his partner’s observation, Bangert stopped behind Stanbridge

and activated his blue flashe rs, effectively seizing Stanbridge. Bangert did so because Stanbridge had not activated his turn signal 100 feet be fore pulling to the curb.

Stanbridge had a valid driver ’s license, but a check for criminal history showed that he “did have priors,” prompting Officer Bangert to reques t a drug-sniffing dog (though Stanbridge’s only drug conviction was for marijuana possession, 11 years earlier when he was 17). The dog arrived
10 minutes later, and its alert led to the discovery of methamphetamine, marijuana, and pills inside Stanbridge’s duffel bag. He was arrested and co nfessed to acting as a “mid-No. 15-2686 3

dleman” for two suppliers who had trafficked six pounds of methamphetamine in as many months.

Stanbridge was charged with conspiracy to distribute a
controlled substance, 21 U.S.C. §§ 846, 841(a)(1), and possession with intent to distribute, id. § 841(a)(1). He moved to suppress the evidence derived fr om the stop, asserting that he was seized unlawfully because he had not committed a traffic violation. The government responded that the police

officers had two bases for seiz ing Stanbridge: He did not activate his turn signal 100 feet before pulling over to park, and he had made a left turn without signaling at all. Videofrom a dashcam in the officers’ patrol car confirms that Stanbridge did not signal for 100 fe et before parking, but, the government conceded, the illegal left turn cannot be seen in

the video.

At a hearing on Stanbridge’s motion to suppress, both police officers testified, and the dashcam video was played.Officer Bangert acknowledged that he had not seen Stanbridge commit a traffic violation before the alleged turnsignal violation when parking. Indeed, Bangert’s only justification for detaining Stanbridge was that he had “started to signal after [his car] already started its turn pulling to the curb.” Officer Hodges, on the ot her hand, testified that hehad seen Stanbridge turn left at an intersection without signaling; he didn’t mention this violation to Bangert when itoccurred, he added, because he had assumed that his partner also witnessed the illegal turn.

Stanbridge’s car did not come in view of the dashcam until just before he parked. Stan bridge was on a street without4 No. 15-2686

lane markings, with no other tr affic in sight (except for the officers’ car). But the video does confirm that Stanbridge activated his turn signal just before he pulled to the right to park, not contemporaneously with the rightward movement as described by the police officers.

The district court denied Stanbridge’s motion in a written

order. The court assumed that Officer Hodges had seen Stanbridge make an unsignaled left turn. But that observation, the court reasoned, would have given Hodges , not Officer Bangert, probable caus e to make a traffic stop:

Officer Hodges

... was not driving the po- lice

car and did not initiate th e traffic stop. Of- ficer Bangert, as the driver, did, but Officer Bangert testified that he did not see Stan- bridge’s left turn without a proper signal. Moreover, both officers testified that Officer Hodges did not tell Officer Bangert about Stanbridge’s unsignaled left turn, and Officer Hodges testified that he had assumed that Of- ficer Bangert saw the turn

for himself.

Thus, the court concluded, the left turn was irrelevant, and only Bangert’s explanation for detain ing Stanbridge could justify the defendant’s seizure. The court opined that the Illinois Vehicle Code is ambiguous (and noted that courts in the state had not offered guidance) concerning whether a driver must signal for 100 feet before pulling to a curb. And,
the district court concluded, Ba ngert’s belief “was reasonable, even if it were mistaken ,” and thus the perceived ambiguity “must be resolved in the Government’s favor.No. 15-2686 5

Stanbridge then entered a conditional guilty plea to the count charging him with possessing the methamphetamine in his duffle bag, while reserving the right to challenge on appeal the denial of his motion to suppress. See F ED . R. C RIM

. P. 11(c)(1)A), (B). He was se ntenced to 144 months’ imprisonment.

II. DISC USSI ON

In this court Stanbridge argues that Illinois law does not require a driver to signal co ntinuously for 100 feet before parking parallel to a curb, and that Officer Bangert’s mistake of law on this point was unreasonable and thus cannot be a basis for upholding the seizure. The government counters that Stanbridge’s challenge is not properly before us because, according to the government, in briefing this appeal he neglected to contest a second reason given by the district court for denying his motion to suppress. We therefore beginwith the government’s contention that Stanbridge has committed waiver.

In opposing Stanbridge’s motion in the district court, the government asserted that his failure to signal before turning
left at an intersection, as seen by Officer Hodges but not captured on the dashcam video, provided a basis for the seizureindependent of Stanbridge’s actions while parking. On appeal, the government’s primary co ntention is that Stanbridgehas waived any challenge to his initial detention by not addressing what the government ch aracterizes as “the district court’s unmistakable finding” of probable cause to seize him based on the unsignaled left tu rn. In his opening brief Stanbridge discusses only Officer Bangert’s justification for the6 No. 15-2686

seizure, and thus, the govern ment argues, Stanbridge has left unchallenged an alternativ e rationale for sustaining his initial detention. This “omission,” the government insists, “is fatal to his appeal.”

To the contrary, waiver is a problem for the government, not Stanbridge. That is beca use the government’s premise rests entirely on its untenable reading of the district court’s ruling. The court’s order, in the opening paragraph, does talk about improperly signaled “turns” giving the “officers” probable cause to make a tra ffic stop. Yet despite these plural references, the court’s decisi on later makes clear that the judge did not accept the govern ment’s contention that itcould rely on both “turns” to justify the detention of Stanbridge. The government correctly observes that the district court thought that Officer Ho dges’s observation of Stanbridge turning left at an inte rsection without signaling provided Hodges with probable cause for a traffic stop, but the government omits what the court said next:

Officer Hodges, however, was not driving the police car and did not in itiate the traffic stop. Officer Bangert, as the driver, did, but OfficerBangert testified that he did not see Stanbridge’s left turn without a proper signal.
Moreover, both officers testified that Officer Hodges did not tell Officer Bangert about Stanbridge’s unsignaled left turn, and Officer Hodges testified that he had assumed that Officer Bangert saw the turn for himself.No. 15-2686 7

The district court thus believed that only Officer Bangert, the driver of the patrol car, had effectuated Stanbridge’s seizure and thus only his ra tionale and the facts known to him mattered. In so doing, the district court rejected the government’s reliance on the unsignaled left turn as a justification for the

initial detention.

The government may disagree with the district court’s reasoning, but it does not argue in its brief that we should reject that reasoning and view the left turn as an alternativebasis for upholding the stop of Stanbridge. By instead misconstruing the court’s order and arguing that Stanbridge has engaged in waiver, the government has failed to recognize

,let alone challenge, the district court’s rejection of its position that the stop was alternatively justified by the unsignaled left turn. The governme nt, like other litigants, can waive its opportunity to challenge an adverse ruling on an argument presented to the district court. See United States v. Cherry , 436 F.3d 769, 772 (7th Cir. 2006) (recognizing thatgovernment “inexplicably abandoned reliance” on valid justification for vehicle search by failing to challenge district court’s rejection of that ground presented at suppression hearing); United States v. Wilson , 390 F.3d 1003, 1009–10 (7th Cir. 2004) (refusing to review fa ctual assertions where government failed to challenge district court’s rejection of those same contentions); United States v. Dyer , 580 F.3d 386, 390 (6th Cir. 2009) (finding waiver where government failed to challenge district court’s dete rmination that defendant had standing to bring Fourth Am endment claim). The government has not asked us to re ject as unsound the district court’s conclusion that only Officer Bangert, not the “team,” seized Stanbridge, and that Officer Hodges’s observation8 No. 15-2686

cannot be considered. The government’s oversight in failing to argue the issue is so large that we conclude it has waived reliance on the left turn as a ju stification for Stanbridge’s seizure.

That leaves Stanbridge’s cha llenge to the sole ground on which the district court did rely: He did not signal for 100 feet before pulling to the curb to park. Section 11-804 of the Illinois Vehicle Code provides:

When signal required. (a ) No person may turn

a vehicle at an intersection unless the vehicle isin proper position upon the roadway as required in Section 11-801 or turn a vehicle to enter a private road or driveway, or otherwise

turn a vehicle from a direct course or move right or left upon a roadway unless and until

such movement can be made with reasonable safety. No person may so turn any vehicle without giving an appropriate signal in the manner hereinafter provided.

(b) A signal of intention to turn right or left when required must be given continuously during not less than th e last 100 feet traveled by the vehicle before turning within a business or residence district, and such signal must be given continuously during not less than the last 200 feet traveled by the vehicle before turning outside a business or residence district.No. 15-2686 9

(c) No person may stop or suddenly decrease the speed of a vehicle wi thout first giving an appropriate signal in the manner provided in this Chapter to the driv er of any vehicle immediately to the rear when there is opportunity to give such a signal.

(d) The electric turn signal device required in

Section 12-208 of this Act must be used to indicate an intention to turn , change lanes or start from a parallel parked position but must not beflashed on one side only on a parked or disabled vehicle or flashed as a courtesy or “dopass” signal to operators of other vehicles approaching from the rear. However, such signal devices may be flashed si multaneously on bothsides of a motor vehicle to indicate the presence of a vehicular traf fic hazard requiring unusual care in approaching, overtaking and passing.

625 ILCS 5/11-804. Stanbridge di sagrees with the district court’s belief that this statute is ambiguous concerning the 100-foot minimum signaling distance. Stanbridge is willing to concede that moving from a t raffic lane to a curb is a lane change governed by § 11-804(d), but even so, he argues, the statute requires only that a signal “must be used” when changing lanes, not that a sign al be used for 100 feet or any other specified distance. In response, the government has abandoned its previous argument that pulling to a curb constitutes a “turn” re quiring a 100-foot wa rning, and instead the government argues that a “driver cannot ‘indicate an in-10 No. 15-2686

tention’ to change lanes while he is already changing lanes,” because to do so would fail to give other drivers sufficient

notice and defeat th e statute’s purpose.

We agree with Stanbridge that § 11-804 is not ambiguous, and does not require a driver to signal for 100 feet before pulling alongside a curb to park. The minimum signalingdistances required by subsection (b) apply only when a driver intends “to turn right or left” (emphasis added). And noother subsection includes an explicit command to signal before moving toward a curb to park. As the district court noted, “[i]f the Illinois General Assembly had meant for the signal requirement to apply to a motorist pulling to a stop at the curb under § 11-804(d), it knew how to do so explicitly, as § 11-804(d) clearly requires th e use of a turn signal before‘start[ing] from a parallel parked position’.” This is a sensible reading of the statute, and the government has not given

us reason to think that the le gislature intended to requiredrivers seeking parking in congested urban areas to continuously signal for 100 feet befo re determining that a possible parking space is not only large enough, but also free of fire hydrants, yellow curbs, and other parking restrictions.

So the only possible relevance of § 11-804 is the requirement in subsection (d) that a si gnal be used to indicate an intention to “change lanes.” “Lane” is not defined (and the
Illinois courts have not had occasion to construe the term, especially as applied to an un striped roadway). But even ifmoving toward the curb of unstriped pavement to park constitutes “changing la nes,” § 11-804(d) requires only that a turn signal “be used.” And Stanbridge did use his signal, as the government is compelled to acknowledge. What’s more,No. 15-2686 11

the dashcam video refutes the government’s assertion that Stanbridge activated his turn signal only after pulling toward the curb; the light was on before Stanbridge moved to the right.

This does not end our inquiry, however, because a police

officer’s objectively reasonable mistake of law can provide reasonable suspicion for a seizure. See Heien v. North Carolina

, 135 S. Ct. 530, 534–35, 539–40 (2014) (concluding that policeofficer’s mistaken belief that ambiguous vehicle code required more than one functiona l brake light was objectively reasonable). The district court concluded that Officer Bangert was objectively reasonab le, even if mistaken, in believing that § 11-804 requires moto rists to signal for at least 100 feet before pulling to a cu rb. Rather than defend this conclusion, the government in it s brief dismisses as an “academic proposition” Stanbridge’s argument that the district

court erred.

We view the government’s silence as an implicit concession that, as Stanbridge mainta ins, Officer’s Bangert’s misunderstanding of § 11-804 was not objectively reasonable. The statute isn’t ambiguous, and Hein does not support the proposition that a police officer acts in an objectively reasonable manner by misinterpreting an unambiguous statute.
See United States v. Flores , 798 F.3d 645, 649–50 (7th Cir. 2015)(concluding that police officer could not reasonably have believed that motorist’s use of license-plate frame found on

“vast” number of cars violated Illinois statute). The 100-foot requirement in § 11-804(b) unam biguously applies to turns, and nothing more. Ba ngert simply was wrong about what the provision required, yet “an officer can gain no Fourth12 No. 15-2686

Amendment advantage through a sloppy study of the laws he is duty-bound to enforce.” Hein , 135 S. Ct. at 539–40.

The government suggests that we disregard whether Officer Bangert acted reasonably and instead declare that Stanbridge violated § 11-804 for a reason unrelate d to the 100-foot signaling minimum. In the government’s eyes, Stanbridge signaled “too late” and failed to give adequate warning to other drivers. For this proposition the government relies on the requirement in § 11-8 04(c) that drivers give notice to vehicles directly behind th em before suddenly decreasing speed if “there is opportunity to give such a signal.” The government also echoes the district court’s statement that “the overall purpose of the stat ute is plainly to regulate themovement of vehicles and to provide notice of that movement to other motorists.”

It should suffice to note that this argument wasn’t made

in the district court and is thus forfeited. See

, e.g. , United

States v. Dachman , 743 F.3d 254, 259 (7th Cir. 2014); Fryer v.

United States , 243 F.3d 1004, 1011–12 (7th Cir. 2001). Anyway, who else was on the road to warn? Once again the dashcam video upends the government’s contention; as is plain from that video, the police officers’ distant patrol car was the only other vehicle in sight of St anbridge, and he already was moving slowly when he decided to pull over and park.

III. CONC LUS ION

Stanbridge fully complied with § 11-804. Officer Bangert’s contrary belief was not objectively reasonable, and thus the officer’s mistake of law cannot justify Stanbridge’sNo. 15-2686 13

seizure. Accordingly, the denial of the defendant’s motion to suppress must be overturned. Th e judgment of conviction is
VACATED, and the case is REMANDED to the district court for further proceedings.
