If you ain't got CPC and claim you are only driving to the work place and your full time job is a scaffolder then you must produce your scaffolders card , if you ain't got one then they deem you as a driver and need CPC ,
And make sure you have a daily walk around check book filled in with you as that's another bee in their bonnet ,
And make sure you log your rest breaks and don't exceed the weekly rest breaks ( basically you can only drive every other Saturday ),
I got done 18 months ago for driving 6 days in a row and the fine is £100 per hour lucky I was only 3 hours out so it cost me £300 plus they give you a mandatory 48 hours no driving rest there and then so someone has to come get the lorry
