§ 3334.  Turning movements and required signals.

(a)  General rule.--Upon a roadway no person shall turn a vehicle or move from one traffic lane to another or enter the traffic stream from a parked position unless and until the movement can be made with reasonable safety nor without giving an appropriate signal in the manner provided in this section.
