From this point onward, a Transvaal vehicle's origin could no longer be narrowed down to a specific town or city. However the first letter of the registration indicated the date of first registration of a vehicle, as the sequence grew alphabetically. However, because the Transvaal used codes that coincided with those used in other provinces, traffic officers failed to notice the T at the end, and issued fines to Cape motorists whose registrations matched those of T vehicles passing through the Cape. The use of C and N codes ought to have been barred. O was not used, since the new system avoided the use of vowels.
