May an officer prolong a routine traffic stop for four and a half minutes to allow a drug dog to sniff the exterior of the vehicle–even if the officer lacks reasonable suspicion to believe that drugs are in the car? Yes she may. The court of appeals held this week in State v. Sellars, No. … Read more
Drunk drivers have difficulty driving in a straight line. Therefore, police officers frequently stop drivers who are weaving, suspecting them of impaired driving. Until very recently, it seemed that the law was settled that weaving alone could not support a DWI stop. Rather, “weaving plus,” or weaving combined with some other circumstance suggesting impairment, was … Read more
Jeff has written before about whether a traffic stop may be prolonged to allow time for a drug-sniffing dog to arrive on the scene and sniff about the car (which itself is not a Fourth Amendment search, see Illinois v. Caballes, 543 U.S. 405, 409 (2005)). As Jeff noted in his paper, it is unclear … Read more
Two recent cases from the court of appeals have added to our state’s weaving jurisprudence. One of them is a pretty big deal, as I’ll explain below. But first, the background.

Recently, I returned to the subject and completed a pretty detailed primer on traffic stops and the Fourth Amendment. The paper, which is available here, treats traffic stops chronologically. First it addresses when a traffic … Read more

It’s also reasonably clear that the officer can order the vehicle’s occupants to remain in the vehicle. Robert L. Farb, Arrest, Search, and Investigation in North Carolina 30 & n.160 (collecting cases). … Read more
As one eminent Fourth Amendment scholar has observed, “[i]n recent years more Fourth Amendment battles have been fought about police activities incident to . . . what the courts call a ‘routine traffic stop’ than in any other context.” 4 Wayne R. LaFave, Search and Seizure § 9.3 (4th ed. 2004). Because so many criminal … Read more
Several recent inquiries have been variants of the following question: can an officer administer field sobriety tests during a routine traffic stop? In other words, if an officer has reasonable suspicion that a driver has committed a traffic violation, and has a hunch, not rising to the level of reasonable suspicion, that the driver is … Read more
