I am one of those horrid people who take your money and subject you to 7 hrs of listening to me spout BS.
I have had both drivers & TMs tell me that my training is far from dull or boring.
The reason is that I was a Class 1 driver for over 27 years before being taken off the rd due to health reasons.
Luck was on my side as I was an Agency driver & the agency being a very large one deemed it a good idea to have most of their trainers be ex drivers or a few are still drivers.
Most information for drivers is from other drivers(MMTM) or from a TM who wants lots of work done for minimum pay.
Most of the drivers on my training days go away more informed than when they arrived.
