The circumstances of this case do not legitimize the stop. Law enforcement must have reasonable and articulable suspicion of a traffic violation, the commission of a crime, or unlawful activity before executing a traffic stop. Accordingly, the roadside statement given by defendant during the unlawful stop should have been excluded at trial, and the Court affirms the Appellate Division’s reversal of her convictions for hindering apprehension and false reporting. Because defendant’s roadside statement permeated the trial, severely affecting her credibility and ability to mount a defense to the separate burglary charge, that conviction is reversed as well.
