When I give the number signal I immediatly point behind me with my thumb. I find that most people catch on once you motion behind you.
Another signal I use is a raised hand/arm above my head to get the attention of the rider behind me if a dangerous obstacle is approaching, such as a drop-off or hidden ditch. :eek:
