Q3. Will I get a criminal record if I am convicted of an offence under the regulations/by-laws?
Yes.
Offence includes any crime and any contravention or other breach of, or failure to comply with, any provision of any law, for which a penalty is provided: see Section 3 of the Interpretation and General Clauses Ordinance (Cap. 1).
Thus, a person will commit an offence if he or she contravenes, breaches or fails to comply with any provision of any relevant ordinance, regulations and By-laws governing the conduct on a public transport, for which a penalty is provided.
The commission of an offence would necessarily leave a criminal record.
