(A) The driver of any vehicle upon a highway, before starting, stopping or turning from a direct line, shall first see that the movement can be made in safety, and if any pedestrian may be affected by the movement, shall give a clearly audible signal by sounding the horn, and whenever the operation of any other vehicle may be affected by the movement, shall give a signal, plainly visible to the driver of the other vehicle, of the intention to make the movement. The signal shall be given either by means of the hand and arm in the manner specified, or by a mechanical or electrical signal device, authorized by state law, except that, when a vehicle is so constructed or loaded as to prevent the hand and arm signal from being visible both to the front and rear, the signal shall be given by device of a type which has been approved by the State Department of Motor Vehicles.
(B) A signal of intention to turn right or left, when required, shall be given continuously during not less than the last 100 feet traveled by the vehicle before turning.
(C) Whenever the signal required by this section is given by means of the hand and arm, the driver shall indicate his or her intention to start, stop or turn by extending the hand and arm from the left side of the vehicle in the following manner, and the signals shall indicate as follows:
(1) Left turn. Hand and arm extended horizontally;
(2) Right turn. Hand and arm extended upward; and
(3) Stop or decrease speed. Hand and arm extended downward.
