Yes, as far as I can recall, upon arrival at the ambush point the indicator lights had to flicker from sharp to dull and that would give us a pre-warning and then he would have to pull away or pull over into the ambush area.  The driver would have to jump out and run around the front of the vehicle.  In other words, in the same direction or line as that in which we had been set up for the ambush.
