For both Code 404 & Code C4C the new owner has to be a member of a “DoT (Dept of transport) approved historic motoring club” and have a CMC1 form completed by an Authorised Person of the Club that the new owner belongs to, in the case of the VCC WA this is will be the any of clubs approved vehicle inspectors, for this the vehicle may need to also be inspected by the clubs vehicle inspectors. This will need to be presented to the DoT together with the DOT transfer of ownership form.
If you are transferring ownership and there is not a CMC1 form with the DoT transfer form, then the vehicle will be put onto a full license. In the case of Code 404 this will mean that if the vehicle has never been on a full license, then the vehicle will need to undergo a full DoT vehicle inspection to be put onto a full license.
