Drink driving may be a criminal offence for the purposes of declaration on an application form but it is not a criminal offence by definition as it does not get criminal number. Once the 11 years is spent the record ceases. I think the point would be that any question asked on the application is likely to be, have you EVER been convicted. In which case the answer would have to be ‘yes’ regardless of how long ago the incident happened. At a point where thousands of applicants are applying for one post, and where even a spelling mistake on a CV could cost you a place, I think a yes to that answer would be the end of you.
Sorry but this is not correct. Despite the myths the CRO number you are referring to has nothing to do with criminal offences and relates only to confirmation that fingerprints are held and indexed in the criminal records office!
Drink drive is a criminal offence and does not get archived. Like all criminal convictions they now stay on record for 100 years following the enquiry which followed the Ian Huntley murders.
The only relevant questions are around when they are disclosable and when they are disclosed.
