Regulation 90

Hand signals are given not only for the benefit of following traffic but also for oncoming traffic, traffic waiting in side streets and pedestrians. Most cars today have signalling devices but in broad daylight hand signalling is more readily seen and understood. Do not allow passengers to give hand signals. See that children do not hold their arms or dangle toys out of the windows of the car, for their arms or toys may be mistaken for hand signals. It is also dangerous for children to do this.
