facts that, together with rational inferences drawn from them, reasonably warrant a

suspicion that the individual to be stopped is, or has been, engaged in criminal

activity. United States v. Cortez, 449 U.S. 411, 416 (1981) (discussing United States

v. Brignoni-Ponce, 422 U.S. 873, 884 (1975)). Reasonable suspicion supports the

first traffic stop. The record shows that Rizzo drove north on State Route 90 and

conducted a U-turn immediately before a Border Patrol checkpoint, after passing 11

opportunities to turn around, as well as a sign indicating the checkpoint was open.

After the U-turn, Border Patrol agents followed Rizzo as she took a strange route

south, then east, away from population centers and the vehicle’s registration address.

1 We grant Rizzo’s request for judicial notice of a Google map of southern Arizona, Docket No. 10, see United States v. Perea-Rey, 680 F.3d 1179, 1182 n.1 (9th Cir. 2012), and grant her request to extend a deadline for briefing, Docket No. 40.

2 Border Patrol agents also knew that license plate data indicated that the vehicle had

been driven in the area multiple times, suggesting the driver was not lost. While

Rizzo contests this reading of the data, the agents were entitled to make that

reasonable inference. See United States v. Arvizu, 534 U.S. 266, 273 (2002)

(requiring courts to give “due weight” to law enforcement agents’ factual inferences

(simplified)). As the district court held, the totality of this evidence suffices to

constitute reasonable suspicions for the first traffic stop.

Rizzo’s arguments to the contrary fail. First, her assertion that the U-turn

cannot contribute to a finding of reasonable suspicion is incorrect. To be sure, a

turnaround on a highway may contribute to reasonable suspicion only when

combined with other suspicious facts. United States v. Montero-Camargo, 208 F.3d

1122, 1137–38 (9th Cir. 2000) (en banc). But such additional facts were present

here, as Rizzo passed 11 opportunities to turn around, turned only after passing a

sign indicating that the checkpoint was open, and subsequently took a route

appearing inconsistent with innocently missing an exit or returning for gas or another

nearby destination. Id. at 1139 (holding reasonable suspicion supported a traffic stop

when vehicles made U-turns on a highway while hidden from view of border

officials, then stopped at a location historically used for illegal activities before

continuing).

3 Rizzo’s assertion that driving on a paved, public highway was not inherently

suspicious misses the mark as well. While the defendant’s presence on public

highway only minimally contributed to reasonable suspicion, where “substantially

all” the traffic was lawful, United States v. Sigmond-Ballesteros, 285 F.3d 1117,

1124 (9th Cir. 2002) (simplified), the agents did not base their suspicions on Rizzo’s

presence on a public highway alone. Rather, the agents observed her U-turn

immediately before the Border Patrol checkpoint and her unusual route. See United

States v. Tiong, 224 F.3d 1136, 1140 (9th Cir. 2000) (holding that using an unusual

or erratic route may contribute to a finding of reasonable suspicion).

Rizzo’s U-turn, combined with her unusual route and unlikelihood of being

lost, provided reasonable suspicion for the agents to conduct the first stop. Because

Rizzo’s objections to the second stop are based purely on the unconstitutionality of

the first stop, those arguments also fail.

AFFIRMED.
