When can police extend a traffic stop to investigate impairment? State v. Stewart Explained

2014 UT App 289
No. 20130672-CA

Summary

Defendant was convicted of drug possession charges after police extended a traffic stop based on observations of impairment symptoms and obtained incriminating statements following Miranda warnings. She appealed claiming ineffective assistance of counsel for withdrawing one suppression motion and filing another motion late.

Analysis

In State v. Stewart, the Utah Court of Appeals addressed when police officers may extend routine traffic stops to investigate suspected impairment and clarified the standards for evaluating ambiguous Miranda invocations of counsel.

Background and Facts

A police officer stopped Stewart for non-functioning taillights. During the stop, the officer observed that Stewart was jittery, dancing around in her car, had constricted pupils that didn’t respond to light, and was slurring her words. Stewart told inconsistent stories that didn’t make sense. The officer, a certified drug-recognition expert, recognized these symptoms as consistent with narcotic use. After learning from probation officers that drug paraphernalia had been found at Stewart’s residence, the officer extended the stop to conduct field sobriety tests, which Stewart failed. Following her arrest, Stewart made incriminating statements after receiving Miranda warnings.

Key Legal Issues

Stewart claimed ineffective assistance of counsel on two grounds: (1) counsel’s withdrawal of a motion to suppress evidence from the extended traffic stop, and (2) counsel’s late filing of a motion to suppress statements allegedly obtained in violation of Miranda rights.

Court’s Analysis and Holding

The court applied the two-step test for traffic stop reasonableness under the Fourth Amendment. While the initial stop was justified, the court examined whether extending the stop was reasonably related in scope to the circumstances. The officer’s observations of Stewart’s jittery behavior, constricted pupils, slurred speech, and inconsistent stories provided reasonable, articulable suspicion that she was operating under the influence, justifying the extension for field sobriety testing.

Regarding the Miranda claim, Stewart’s statement that “there would be some questions she probably would want an attorney with” constituted an ambiguous request for counsel. The officer properly clarified by explaining that if she wanted an attorney, he couldn’t question her. Stewart then expressed willingness to cooperate, constituting a valid waiver.

Practice Implications

This case demonstrates that specific articulable facts observed during a traffic stop can justify extending the detention for DUI investigation. Officers need not have all the traditional indicators of impairment if the totality of circumstances supports reasonable suspicion. For Miranda purposes, ambiguous requests for counsel require clarification, but suspects who subsequently express willingness to talk after clarification may validly waive their rights.
