True … to a point.
Road Traffic Act offences are dealt with (usually) in Magistrates Courts (more serious cases are dealt with in the Crown Courts in front of a Judge etc). – i.e. criminal courts as opposed to being dealt with under civil law in the County Courts or High Court.
Breaches of these laws are prosecuted in the form “R – vs – Bloggs” as opposed to “Smith – vs – Bloggs” ….. thus Road Traffic offences are criminal offences dealt with under the criminal law system.
