DUI: Reasonable Suspicion for Traffic Stop

· “Violation of motor vehicle codes provides an officer reasonable suspicion to initiate a traffic stop. A traffic stop supported by reasonable suspicion of a traffic violation remains valid until the purpose of the traffic stop has been completed. The officer may not extend the duration of a traffic stop in order to question the motorist on unrelated matters unless he possesses reasonable suspicion that warrants an additional seizure of the motorist. The officer cannot avoid this rule by employing dilatory tactics. See United States v. Jones, 234 F.2d 234 (5th Cir. 2000) (driver's Fourth Amendment rights violated when, after dispatcher reported no problems and officer had completed warning citation except for obtaining the driver's signature, officer deliberately delayed completing the stop for several more minutes until canine search unit arrived).” State v. Provet, 405 S.C. 101, 108 (2013) (citations omitted)



· “‘Violation of motor vehicle codes provides an officer reasonable suspicion to initiate a traffic stop…The test whether reasonable suspicion exists is an objective assessment of the circumstances; the officer's subjective motivations are irrelevant.’ ‘[C]ourts must give due weight to common sense judgments reached by officers in light of their experience and training.’ At bottom, in evaluating whether an officer possesses reasonable suspicion, this Court must ‘consider the totality of the circumstances—the whole picture’” State v. Moore, 415 S.C. 245, 252–53 (2016)
