Mirroless training

So our place have 2 new rigid trucks that are mirroless.
The drivers been told they can’t use them unless they’ve been trained and signed off on them.
Anyone else had this?.
And what exactly would training involve.
Apart from you look into screen it acts like a mirror.
Or do they have be turned on set up etc?

i was never trained but its a completely different view in my opinion. I was told by the assesor at the place they never had to be adjusted just jump in and drive. Apparently however there are all sorts of tricks to them.

When I drove for HZ you had to be trained prior to being let loose. I never did the training and consequently never drove one.

Fast forward to my current employment and the first time I touched one was after being driven in a car up to Leeds to pick one up and drive 2 miles to an about to be opened power station where a film crew were waiting to film me for the day performing complex manoeuvres fo the day! Talk about a baptism of fire!

I’ve now been driving one for around three months and still consider them to be a solution to a problem that doesn’t exist.
