Section 16 of the Road Transport Act 1999 provides for an on-the-spot fine in lieu of prosecution for offences under the Road Transport Acts and EU regulations on drivers' hours and rest periods. The commencement of this section has been the subject of discussions with the Attorney General's office and the advice now is that a provision in primary legislation will be required to ensure compatibility with current fixed penalty charges legislation before the proposed fines system can be brought into effect.
