Tachograph Rules Simplified Please

Glad to see i’m Not the only one that found there seems to be more than one way to interpret this.

I have got an O License as the equipment is fixed in the trailer, therefore cannot be removed to achieve an“unladen weight”.

Whilst most of what I do is within 100kms of base, should i want to go further then I would need to be set up.

I really just want to know what I need to do?

Vehicle has a digital Tacho and I have just got it calibrated, I know I need a drivers card.

Think I need a company card, the rest I am still unsure about.

Can anyone tell me what I need to do, card reader■■? Software■■?

Needs to be as simple and cheap as possible.
