As It happens, I've just been on one module of the cpc this morning. For us, as a company the lads driving 7.5 ton lorries to site, erecting the scaffold and then returning to the yard do not need the cpc. BUT if we send out the roll on roll off to one site and then on to another then the driver needs the cpc. It's all down to the interpretation of whichever vosa operative stops you as to which way the wind may blow. so to be safe I'm putting all the lads through it just to avoid any future problems.
