Because the State’s ability to prove impairment in prosecutions for driving while impaired often turns on whether the officer had probable cause to arrest — and thereafter test — the defendant, probable cause to make a warrantless arrest is a frequently litigated issue in DWI cases. While for many years there was a dearth of case law exploring the hard calls in this area, that trend has changed. In several arguably close cases over the past decade, the appellate courts have considered whether impaired driving arrests by law enforcement officers were supported by probable cause. See State v. Parisi, 372 N.C. 639 (2019) (driver’s admission to drinking, his red and glassy eyes, his odor of alcohol, and multiple indicators of impairment on field sobriety tests established probable cause; affirming court of appeals’ opinion reversing trial court); State v. Lindsey, 249 N.C. App. 516 (2016) (odor of alcohol on driver’s breath, red and glassy eyes, admission to drinking, and five clues of impairment from horizontal gaze nystagmus test provided probable cause; affirming trial court order denying motion to suppress); State v. Overocker, 236 N.C. App. 423 (2014) (light odor of alcohol and consumption of three alcoholic drinks in four-hour period were insufficient to establish probable cause; affirming trial court order granting motion to suppress); and State v. Townsend, 236 N.C. App. 456 (2014) (driver’s odor of alcohol, positive results on portable breath test, bloodshot eyes, and signs of impairment while performing field sobriety tests established probable cause; affirming trial court’s denial of motion to suppress).
Last December, the North Carolina Supreme Court added to that list with its opinion in State v. Woolard, ___ N.C. ___, 894 S.E.2d 717 (2023) reversing, upon certiorari review, the trial court’s determination that an arresting officer lacked probable cause for impaired driving. This post will review Woolard, its holding, and its path to the state’s highest court.
