what does dropping your left hand behind your back mean??
I'd have thought they mean something like these :
NSFW

usually means obstruction ahead on the left, parked car etc.
sounds about right, cheers

That appeared a bit quick?
Left hand down = obstruction on the left (parked car/pot hole/broken glass etc)
Same for the right
Either hand down and waving from side to side means 'all over' as in pot holes right across the road etc
I know them off by heart
either hand waving from the small of ones back would indicate an especially smelly fart?
As above but also right hand flat palm out means 'slowing'
[i]either hand waving from the small of ones back would indicate an especially smelly fart? [/i]
Surely that gets no warning, so following friends get the full effect. 🙂
