California Vehicle Code Section 22106 pertains to the requirements for signaling when making a turn. It mandates that a driver intending to turn right or left upon a highway, or to turn from a direct course or move right or left upon a highway, must give a signal plainly visible to the driver of another vehicle or a pedestrian reasonably affected by the movement. This signal must be given either by hand and arm or by a signal lamp or mechanical device. A practical example would be a driver signaling a left turn at an intersection to alert oncoming traffic and pedestrians of their intended maneuver.
Adherence to this regulation is crucial for promoting road safety and preventing collisions. By clearly indicating turning intentions, drivers provide essential information to other road users, allowing them to anticipate and react accordingly. The consistent application of this section contributes to the predictability and orderliness of traffic flow, reducing the risk of accidents and promoting a safer driving environment. Historically, such signaling requirements have evolved alongside the increasing complexity of roadways and the growing number of vehicles, reflecting a continuous effort to mitigate risks associated with vehicular movement.
