Example 3: power generator fixed to the bed of a vehicle
A driver drives a lorry with a power generator fixed to the bed of the vehicle, but driving isn’t their main activity. They drive to road maintenance sites where the generator is used to power site equipment. They do various tasks at the site, including monitoring the generator to make sure it’s working correctly.
They don’t need Driver CPC.
