You don’t need Driver CPC if you’re carrying equipment or material that you’ll use in the course of your work, provided that driving the vehicle is not the main part of your job.
This includes:
trade tools
goods such as building materials or cables to be used by the driver in the course of their work
extra crew like a mechanics mate or any other person needed for the job

They do not need Driver CPC. If they use engine diagnostic kit that’s fixed within the vehicle, they would also be covered by the exemption because the vehicle carries material or equipment for their use on site.
Driver B
Driver B is a self-employed bricklayer and drives their lorry to a building site with a load of bricks. They unload the bricks and use them in the construction of a house.
