§ 312-14. Signaling by drivers.

A. 

Turning. Before turning to the right or left and except in an emergency, before decreasing speed or stopping, the driver of a vehicle shall give warning either by holding his arm straight out horizontally and at right angles to the vehicle or by operating an adequate mechanical signaling device.

B. 

Signals. The driver of a vehicle shall, before turning while in motion or from a standstill or changing the course of such vehicle or before starting from a standstill when parked, first see that there is sufficient space to make such movement in safety and shall give a visible or audible signal to the peace officer, if there is such, or to drivers of other vehicles of his intention to make such movement by signaling as provided in this section, and when a peace officer is in charge of the traffic, indicate to him the direction in which the vehicle is to be turned.

C. 

Backing. Before backing any vehicle, the driver shall see that the way is clear and shall give adequate warning and shall, while backing, exercise due vigilance to prevent an accident.

D. 

Passing. The driver of an overtaking vehicle shall signal his desire to pass an overtaken vehicle by a blast or stroke of the horn or other signaling device, and thereupon it shall be the duty of the driver of the overtaken vehicle, if possible, to turn to the right so as to allow the overtaking vehicle a reasonable space in which to pass or to warn by signal the impossibility of such passage.
