(cf Gen Act, s 179(8))
Despite section 184, the responsible person for a vehicle who is issued with a
penalty notice or a court attendance notice in respect of a
camera recorded offence is not guilty of that offence by operation of that
section if the person--
(a) complies with section 186 in relation to the offence, or
(b) satisfies the authorised officer (in the case of a penalty notice) or the court (in the case of a court attendance notice) that the responsible person did not know and could not with reasonable diligence have ascertained the nomination details of the person who was in charge of the vehicle at the time the offence occurred.
