217.This section adds the offences of kerb crawling and failure to stop and report an accident (in which personal injury is caused) to the list of offences in section 24 (2) of the Police and Criminal Evidence Act 1984 for which a power of summary arrest exists. Making these offences arrestable enables the police to take offenders into custody and question them rather than having to summons them to appear at a magistrates’ court to answer the charge.
