I have recently used the services of Auriga, and I can say that I was extremely happy with their professionalism, knowledge, and experience with driving offences.
Driving Licence Offence Codes and Endorsements
If you have been convicted of an offence a record is put on your licence to show
the offence and the level of endorsement or disqualification. The offences only
appear on your licence by way of a code which represents an offence e.g. CD10
represents Driving without due care and attention.
