Waiting on licence return

Waiting on my provisional licence to come back from the dvla. Whilst doing this I am revising my theory questions and hazard perception.

What can I do to revise for the cpc module 2 and 4?

I’m currently a flt driver, so see many wagons in a week.

Ask the drivers what they do for walkaround checks. Ask them on how the tachos work because you won’t get tested on that and when you do get behind the wheel you will be expected to know what your doing with them.
