your right hand, and signal stream C to proceed by swinging your left hand towards your head and bringing it to a final position directly back of your ear (figure 10-6), while holding your upper arm horizontal. If you want the traffic to pass in front of you, as stream D. in figure 10-7, check stream C with one upraised palm, and signal stream D to move in front of you by swinging the other hand and forearm towards you and bringing the hand to a final position just in front of the nearest shoulder. Note that in both these signals the upper portion of the beckoning arm is extended horizontally and directly sideways. If you want traffic to proceed at the same time in both directions, as in streams C and D in figure 10-4, the two "Go" signals described above are given at the same time. "Go" signals should not be repeated unless necessary. To speed up slow moving traffic, the "Go" signal is repeated rapidly several times with either one or both arms, depending on whether the signal is intended for one or both moving streams. You must be careful to limit repetition of the "Go" signal, so that traffic will not exceed normal speed. The sequence of movements used in regulating alternate two-way traffic flow at an intersection is shown in detail in figure 10-1. Figure 10-8 illustrates a stop signal given to one traffic stream only. TURNS. (Figure 10-9 (A), 10-9 (B) and 10-9 (C).) A permissible turn is indicated by swinging your arm as in the "Go" signal, except that on completing the swing the arm is extended with the hand pointing in the direction of the turn. Before signaling a left turn, be sure to stop traffic coming from the opposite direction. To signal a left turn, use one arm for the turn signal, and the other to stop any through traffic from the opposite direction. If a driver indicates that he wants or intends to make a prohibited turn, shake your head to indicate “No,” and then indicate by arm signal whether he is to proceed straight through or stop until you signal him to make the turn. The whistle may be useful in such a case to attract the driver's attention. Night Signals Night signals (except under blackout conditions) are made by lighted batons, consisting of a flashlight with an amber-colored extension. If these are not available, ordinary flashlights may be used. Such lights are not turned on when not actually in use for signaling. Signals are made as follows: STOP! (Figure 10-10 (A).) Hold the baton in an upright position and wigwag it several times, swinging it about 45 degrees to each side from the vertical position. |
