Utah Court of Appeals
Can police stop a driver based on a vague report of drinking? State v. Roybal Explained
Summary
Roybal’s girlfriend called 911 to report a domestic dispute, stating they had both been drinking and that Roybal was leaving in a white van. Sergeant Ledford stopped Roybal based on the dispatch report and his observation of slow, cautious driving. The trial court denied Roybal’s motion to suppress evidence obtained after the stop.
Analysis
The Utah Court of Appeals addressed an important Fourth Amendment issue in State v. Roybal, examining whether a traffic stop was justified based on a 911 call reporting that someone had been drinking.
Background and Facts
Roybal’s live-in girlfriend called 911 to report a domestic dispute. She stated that Roybal had “just about” assaulted her and that they both had been drinking. She provided no details about the quantity or type of alcohol consumed or the time period during which the drinking occurred. The dispatch operator characterized Roybal as “very intoxicated,” though the girlfriend never used that term. Sergeant Ledford located Roybal’s van and observed him driving slowly and cautiously in what appeared to be a right-turn pattern near the residence. Based on these observations and the dispatch report, Ledford stopped Roybal, who was subsequently arrested for DUI.
Key Legal Issues
The central issue was whether the officer had reasonable suspicion to justify the traffic stop under the Fourth Amendment. The court examined three factors: (1) the reliability of the 911 call, (2) the content of information provided by the caller, and (3) whether the officer’s own observations supported reasonable suspicion.
Court’s Analysis and Holding
The court found the 911 call lacked sufficient reliability because the caller was potentially biased as a significant other following an argument, appeared intoxicated herself, and provided no meaningful details about criminal activity. Critically, the court held that merely stating someone “had been drinking” without additional details about quantity, type of alcohol, time period, or the person’s physical size does not provide an adequate basis to infer legal intoxication. The officer’s observations of slow, cautious driving were insufficient, as such behavior is common when drivers see police and not indicative of criminality.
Practice Implications
This decision emphasizes that suppression motions should focus on the specificity of information supporting reasonable suspicion. Defense attorneys should examine whether 911 calls provide concrete, articulable facts about intoxication rather than vague statements about drinking. The court’s analysis also highlights the importance of evaluating informant reliability when the caller has a personal relationship with the suspect and potential bias.
Case Details

State v. Roybal
Citation
2008 UT App 286
Court
Utah Court of Appeals
Case Number
No. 20060911-CA
Date Decided
July 25, 2008
Outcome
Reversed
Holding
A 911 caller’s report that a person had been drinking, without additional details about quantity, type of alcohol, or time period, combined with driving slowly and cautiously, does not provide reasonable suspicion to justify a traffic stop for driving under the influence.
Standard of Review
Clear error for factual findings, correctness for conclusions of law. In search and seizure cases, non-deferential review applies to the application of law to underlying factual findings.
Practice Tip
When challenging DUI stops based on 911 calls, examine whether the caller provided specific, articulable facts about the level of intoxication rather than merely stating that drinking occurred.
