Whether there was probable cause to arrest the driver is a hotly litigated issue in cases involving impaired driving. Unfortunately, there aren’t all that many appellate opinions addressing the hard calls in this area. Instead, many resemble State v. Tappe, 139 N.C. App. 33, 38 (2000), which found probable cause based on “defendant’s vehicle crossing the center line, defendant’s glassy, watery eyes, and the strong odor of alcohol on defendant’s breath.” It is difficult to imagine a court ruling otherwise. A few years ago, the court of appeals decided a tougher issue in Steinkrause v. Tatum, 201 N.C. App. 289 (2009), aff’d, 364 N.C. 419 (2010) (per curiam), concluding that the “fact and severity” of the defendant’s one-car accident coupled with a law enforcement officer’s observation that she smelled of alcohol provided probable cause to believe she was driving while impaired. This past year, the court issued two significant published opinions on probable cause for impaired driving—State v. Overocker, __ N.C. App. __, 762 S.E.2d 921 (Sept. 16, 2014), and State v. Townsend, __ N.C. App. __, 762 S.E.2d 898 (Sept. 16, 2014),—as well as opinions in State v. Veal, __ N.C. App. __, 760 S.E.2d 43 (July 1, 2014), and State v. Wainwright, __ N.C. App. __, 770 S.E.2d 99 (2015), better defining the threshold for reasonable suspicion of DWI.
