People v. Greenwood

In People v. Greenwood (2010) 189 Cal.App.4th 742, the court addressed a traffic stop to investigate registration where there was a tag displayed, but officers believed the type of tag displayed was for a limited use that would not be applicable to the circumstances in that case. There the court found the officers had an objectively reasonable basis to conduct further investigation to clarify the validity of the car registration. (Id. at pp. 748-750.)
