(1) A mechanical
signalling device required by regulation 329 must —
(a) be
fitted to the right side of the motor vehicle; and
(b) be
able to be operated by the driver from a normal driving position; and
(c)
consist of a white or yellow representation of an open human hand at least 150
mm long; and
(d) be
constructed so that the driver of the motor vehicle can keep the
device —
(i)
in a neutral position so it is unlikely that the driver
of another vehicle or anyone else would regard it as a signal; and
(ii)
in a horizontal position with the palm of the hand facing
forwards and the fingers pointing out at a right angle to the vehicle to
signal an intention to turn or move right; and
(iii)
with the palm of the hand facing forwards and the fingers
pointing upwards to signal an intention to stop or reduce speed suddenly.
(2) When the
mechanical signalling device is in a position mentioned in
subregulation (1)(d)(ii) or (iii), the complete hand must be clearly
visible from both the front and the rear of the vehicle, at a distance of 30
m.
