Hand signalling Question for TOG

Or any others over there in "the old country". I'm pretty sure that hand
signals (in a car) would be made with your right hand as you guys are
sitting in the right hand seat. So, left turn, hand extended up from elbow,
right turn arm extended straight out. So, on a motorcycle, this means you
must release the throttle? In the course of training, testing are hand
signals even mentioned there anymore? I am assuming there is a fair bit of
old iron running around over there with drivers/riders merrily signalling by
hand and getting blank looks and waves back?

 

In the car the hand signals are, IIRC, right arm straight out for
turning right, waved up & down for braking & moved in a circular
direction for left turn.

On a bike it's right arm out for a right turn, left for left & (I think)
right arm up & down for braking - much the same as on a pedal cycle.

Whether anyone other than fans of old vehicles would recognise any of
these is moot - they weren't a formal part of the test when I learnt to
drive.

 

Not that I'm aware, no.
