Arizona Court of Appeals: Traffic Stop Unlawfully Prolonged to Wait for a K-9 — What State v. Avila Means for Your Rights
Quick summary: On August 27, 2026, Division One of the Arizona Court of Appeals affirmed a Navajo County judge’s decision to suppress 25 pounds of methamphetamine and 2.5 pounds of fentanyl found during a traffic stop on Interstate 40. The court held that a state trooper lacked reasonable suspicion to hold the driver, Angel Avila, for 39 extra minutes while waiting for a drug-sniffing dog — even though the trooper cited nervousness, a rental car, a “drug corridor,” and inconsistent travel plans. State v. Avila, No. 1 CA-CR 25-0320, is a reminder that a traffic stop for speeding can’t be turned into a fishing expedition for drugs without real, articulable evidence.
What Happened in State v. Avila?
A Department of Public Safety trooper stopped Angel Avila on I-40 for driving 82 mph in a 75-mph zone. During the stop, the trooper noticed Avila appeared nervous, was driving a rental car, gave what the trooper considered inconsistent travel plans, and stayed on a video call. The trooper also saw a plastic tote in the back seat.
After confirming Avila’s license, registration, and insurance, the trooper decided to issue only a warning for speeding. But while that warning was printing, the trooper asked Avila whether he had drugs in the car. Avila admitted to having marijuana (legal in small amounts for Arizona adults) but denied anything else. The trooper then asked for consent to search the vehicle. Avila initially agreed, then changed his mind and refused after reading a written consent form.
At that point — after the warning had effectively been completed — the trooper called for a K-9 unit. It took 39 minutes for the dog to arrive. The dog alerted, and the resulting search turned up 25 pounds of methamphetamine and 2.5 pounds of fentanyl. The State charged Avila with transportation of a dangerous drug for sale and possession of a narcotic drug for sale.
Why the Superior Court Threw Out the Evidence
Avila’s defense attorney moved to suppress everything found in the search, arguing the trooper had no legal basis to extend the stop once its original purpose — a speeding warning — was finished. The Navajo County Superior Court agreed. After hearing the trooper’s testimony (the State’s only witness), the judge found that, looking at the “totality of the circumstances,” the individual factors the trooper relied on were largely weak, speculative, or common among ordinary, law-abiding travelers.
The State appealed, arguing the trial judge had improperly picked apart each fact instead of weighing them together — a mistake courts call a “divide-and-conquer” analysis, which the U.S. Supreme Court has said is not allowed under United States v. Arvizu. A sharply divided Court of Appeals disagreed with the State, in a 2-1 decision with a lengthy dissent.
The Court of Appeals’ Reasoning
Writing for the majority, Judge Gaona explained that a traffic stop is a seizure under the Fourth Amendment, and the authority to detain a driver ends once the reason for the stop — here, a speeding warning — is complete, unless the officer develops genuine, articulable reasonable suspicion of other criminal activity before that point. The court found the trial judge had, in fact, weighed the circumstances together, and simply explained — at the State’s own request — why several of the trooper’s observations carried little weight once examined closely:
- Nervousness: The trooper himself acknowledged that nervousness is common during traffic stops and that current social conditions can heighten anxiety for some drivers during police encounters.
- “Known drug corridor”: I-40 carries plenty of ordinary travelers, and the trooper agreed not everyone on it is transporting drugs.
- Rental car and short trip: The trooper conceded there are many legitimate reasons to rent a car.
- Inconsistent travel plans: The court found Avila’s statements described different parts of the same trip (visiting family, then giving a cousin a ride), not a contradictory story.
- Refusal to consent to a search: Arizona law is clear that refusing consent is a constitutional right and cannot by itself create reasonable suspicion — otherwise, as the court put it, citizens would face a “Catch-22” where saying yes or no both justify a search.
- The plastic tote: The trooper couldn’t even recall what he was told was inside it, making any inference about hidden contraband purely speculative.
The majority emphasized that appellate courts must defer to a trial judge’s factual findings and credibility calls, and cannot re-weigh evidence just because a different judge — or a dissenting appellate judge — might have found the trooper’s observations more convincing. Because the State didn’t establish that an objectively reasonable officer would have seen enough here to justify holding Avila for the extra 39 minutes, the drugs seized as a result of that extended detention had to be suppressed — regardless of how much was ultimately found.
The Dissent’s View
Judge Foster dissented, arguing the trial court’s explanation of each individual factor showed it had improperly separated the evidence rather than truly considering it as a whole, and that the court substituted its own perspective for that of an objectively reasonable, trained officer. The dissent pointed to the trooper’s 24 years of experience and roughly 25,000 traffic stops, and argued that case law recognizes drug-corridor experience and questionable travel explanations as legitimate factors supporting reasonable suspicion. The majority responded that experience alone doesn’t create reasonable suspicion — the officer still has to connect that experience to the specific facts of the stop, and the State didn’t do that here.
What This Means for You
If you were stopped for speeding, a broken taillight, or any other minor traffic violation — and the stop turned into something bigger — State v. Avila may directly affect your case.
- Once the reason for your stop is resolved (a ticket or warning is issued), the officer’s authority to detain you generally ends unless they can point to specific, articulable facts — not just a hunch — that criminal activity is happening.
- Nervousness, a rental car, a common travel route, or a plastic tote in your back seat are not, by themselves, evidence of a crime. Courts increasingly scrutinize whether these “indicators” actually distinguish you from ordinary, law-abiding travelers.
- Refusing consent to a search is your constitutional right and cannot legally be used against you to justify further detention or a search.
- Waiting for a K-9 unit can be an illegal extension of your detention if the officer didn’t already have reasonable suspicion before your traffic business was finished — timing matters enormously in these cases.
- Even if a search turns up drugs, weapons, or other evidence, that evidence can be thrown out if the stop was unlawfully prolonged to get it. The fact that officers found something illegal does not retroactively justify an unlawful detention.
Why This Matters for DUI and Criminal Cases Alike
Although State v. Avila is a drug trafficking case, its core holding applies with equal force to DUI stops and other criminal traffic stops throughout Arizona. The same Fourth Amendment rules govern how long police can detain you, what counts as reasonable suspicion to extend a stop, and when a request for field sobriety tests, a breath test, or a K-9 sweep crosses the line from a routine traffic encounter into an unconstitutional seizure.
Gordon Thompson has spent 47 years in Arizona courtrooms — much of it filing and arguing motions to suppress evidence obtained through unlawfully prolonged stops, improper searches, and constitutional violations during DUI and criminal investigations. Reviewing body camera and dash camera footage minute-by-minute to pinpoint exactly when a stop’s original purpose ended — and whether anything legally justified extending it — is a routine part of building a defense in these cases. Cases like Avila reinforce that the timeline of a stop, not just the final result, can be the difference between a conviction and a dismissal.

Frequently Asked Questions About Prolonged Traffic Stops in Arizona
How long can police legally detain you during a traffic stop in Arizona?
A traffic stop can only last as long as necessary to handle the original reason for the stop — such as checking your license, registration, and insurance, and issuing a ticket or warning. Once that task is done, the officer’s authority to hold you generally ends unless they’ve developed genuine, articulable reasonable suspicion of a separate crime before that point.
Can police make you wait for a K-9 unit during a traffic stop?
Only if they already have reasonable suspicion of criminal activity before the original purpose of the stop (like a speeding ticket) is finished. In State v. Avila, the Arizona Court of Appeals affirmed suppression of drug evidence because the trooper lacked that reasonable suspicion before calling for a K-9, even though the wait for the dog was less than 40 minutes.
Does refusing to consent to a vehicle search look suspicious to police?
No. Arizona courts have made clear that refusing consent to a search is a constitutional right and cannot legally be used as a factor supporting reasonable suspicion or justifying further detention. If it could, drivers would face a no-win choice where both consenting and refusing lead to a search.
If police find drugs during an illegal traffic stop, can the evidence still be used against me?
Generally, no. If a court finds that a stop was unlawfully prolonged without reasonable suspicion, evidence obtained as a result — even large quantities of drugs — can be suppressed and excluded from trial. Arizona courts have repeatedly held that discovering contraband cannot retroactively justify an otherwise unlawful detention.
Does State v. Avila apply to DUI stops too?
Yes. The Fourth Amendment principles in State v. Avila apply to any traffic stop, including DUI stops. The same rules govern how long police can detain a driver, what justifies extending a stop for field sobriety testing or a breath test, and whether evidence gathered during an unlawfully prolonged DUI stop can be suppressed.
What should I do if I think my traffic stop lasted too long before I was arrested?
Contact a criminal defense attorney as soon as possible and request all available body camera and dash camera footage. An attorney can review the exact timeline of the stop, compare it against Arizona and federal case law on reasonable suspicion, and determine whether a motion to suppress evidence is appropriate in your case.
