This stretches through the other 4 stages, as it is an on going process.
It can be further broken up into 3 sub-sections (TUG):
Take in all the information about what is going on around you. Use that information to decide how you are going to approach what you are doing Give information back, by letting other road users know what you are going to do, for example by indicating.
Make sure you are aware of everything that is going on in front, behind and to the sides, and that should be as far as you can reasonable see, and not just in front of your nose.
