I think this part excludes your mechanic but not for when he/she is relief driving -
your main work activity is not driving lorries, buses or coaches
the vehicle is being driven within a 62 mile (100km) radius of your base
you’re the only person in the vehicle
the vehicle is empty, except for equipment (including machinery) permanently fixed to it (more examples for mechanics at the end)
Exemptions from needing Driver CPC
You do not need Driver CPC if you’re using the vehicle for:
non-commercial carriage of passengers or goods
carrying material or equipment you use for your job, as long as driving is less than 30% of your rolling monthly work
driving for someone you work for, or your own agriculture, horticulture, forestry, farming or fisheries business, as long as driving is less than 30% of your rolling monthly work
driving within 62 miles (100 kilometres) of your base - but the vehicle cannot be carrying passengers or goods, and driving a lorry, bus or coach cannot be your main job
driving to or from pre-booked appointments at official vehicle testing centres
driving lessons for anyone who wants to get a driving licence or a Driver CPC
maintaining public order - and the vehicle is being used or controlled by a local authority
rescue missions or in states of emergency
You also do not need Driver CPC if the vehicle is:
is being road tested for repair, maintenance or technical development purposes
either new or rebuilt and has not yet been taxed
being used or controlled by the armed forces, police, fire and rescue service, emergency ambulance service, prison service or people running a prison or young offender institution
limited to a top speed of 28mph
Carrying material or equipment for use in your work
You do not need Driver CPC if you’re carrying equipment or material that you use in the course of your work. This is because your main activity is not driving. The driving should be less than 30% of your rolling monthly working time.
Example 1: mobile lorry fitter
A driver is a mobile lorry fitter. They drive a vehicle from an operator’s site to another site where they take their tools from the vehicle to do their main activity of servicing lorries.
They do not need Driver CPC.
If they use an engine diagnostic kit that’s fixed within the vehicle, they still do not need Driver CPC. This is because the vehicle is carrying material or equipment for their use on-site.
Empty vehicles within 62 miles of your base if driving is not your main job
You do not need Driver CPC if you meet all of these conditions:
your main work activity is not driving lorries, buses or coaches
the vehicle is being driven within a 62 mile (100km) radius of your base
you’re the only person in the vehicle
the vehicle is empty, except for equipment (including machinery) permanently fixed to it
Example 4: a mechanic who occasionally drives lorries
A mechanic occasionally drives lorries as part of their work.
They do not need Driver CPC for journeys within a 62 mile (100km) radius of their ‘driver’s base’, as long as the lorry is not carrying goods. The ‘driver’s base’ is the place they start work on that particular day - it’s not restricted to one place.
The mechanic’s period on duty will start when they begin work after at least 9 hours off-duty - whether that’s at home, at work, or at a customer’s address. That address will continue to be their ‘driver’s base’ until they’re off-duty for at least 9 hours.
Example 1: mechanic moving empty buses between depots
A mechanic employed by a local bus company moves empty buses between depots in the local area.
They do not need Driver CPC, as driving is not their main activity (as long as they spend less than 30% of their rolling monthly working time driving), and they’re not carrying any passengers.
