Hi,
I am a truck engineer, ITTSAR instructor and fleet manager I have been a trainer for 7 years. On the site I train on I only allow 25 points before failure. I find with counter balance looking is the most common as already stated. reach is the same, and pedestrian stacker I find looking in the direction of travel is a common fault. This is more common than any other.
on my instructor re-test we were told the last thing an operator does is release the brake. this was a change to the previous rule as we used to teach the last thing an operator does was look around.
hope this help
:)
