General descriptionThis annual statistical bulletin contains data relating to motoring offences on:
• Screening breath tests (1992 – 2015).
• Civil parking enforcements, carried out by local authorities, are not covered in this bulletin.
Equivalent data for England can be found at the links for the Home Office and the Ministry of Justice. Transport Scotland publish the number of motor vehicle offences recorded by the police by type of offence in the ‘Road Transport Vehicles’ chapter of the compendium publication titled “Scottish Transport Statistics”: (http://www.transport.gov.scot/statistics/scottish-transport-statistics-all-editions). The Scottish Government publishes the number of people proceeded against in court for motor vehicle offences in the Statistical Bulletin titled “Criminal Proceedings in Scotland”: (http://www.gov.scot/Topics/Statistics/Browse/Crime-Justice/Datasets/DatasetsCrimProc).
The Police Service of Northern Ireland produces statistics on fixed penalty notices: (https://www.psni.police.uk/inside-psni/Statistics/fixed-penalty-notice-fpn-and-discretionary-disposal-statistics-for-traffic-offences/). The Northern Ireland Courts and Tribunals Service publish the number of defendants disposed of in the magistrates’ courts for motoring offences: (http://www.courtsni.gov.uk/en-GB/Services/Statistics%20and%20Research/Pages/default.aspx).
Data collection and calculationData Source
The information on court proceedings reproduces the statistics compiled by the Ministry of Justice in their criminal justice series (https://www.gov.uk/government/collections/criminal-justice-statistics).
The coverage in ‘Police Powers and Procedures’ includes the use of police powers to issue fixed penalty notices for motoring offences. This is broken down by offence type and how they were dealt with (eg. penalty paid or fine registered at court). The data presented are drawn from returns from police forces in England and Wales. The figures also include notices issued by police employed traffic wardens for parking offences. It should be stressed here that most traffic wardens are now employed by local authorities, and their activities are not covered here.

Statistics on Vehicle Defect Rectification notices for motoring offences no longer appear in this bulletin as they were withdrawn from 2009.
The police can require a person to take a screening breath test if they have reasonable cause to suspect that the person has been driving or attempting to drive with alcohol in their body (Section 6(1) of the Road Traffic Act 1988), that they have committed a moving traffic offence (Section 6(1)), or that the person has been involved in an accident (Section 6(2)). A person failing to provide a breath test is guilty of ân offence, unless there is a reasonable excuse.
