Statistical Bulletin CrJ/1999/2: Motor Vehicle Offences in Scotland 1997
 
 
ANNEX
 Notes on Statistics Used in this Bulletin
Scope of bulletin
 
1. The offences covered in the analyses presented in this bulletin are those classified as motor vehicle offences in The Scottish Office Home Department’s classification of crimes and offences. Due to variations in police recording practice, offences of dangerous driving and careless driving have been combined in tables of recorded offences but are shown separately in tables of offences proceeded against. The offence of reckless driving was replaced with the offence of dangerous driving in the Road Traffic Act 1991, brought into force in July 1992.
 
2. Certain crimes related to motor vehicles, namely causing death by dangerous driving, causing death by careless driving while under the influence of drink or drugs and reckless driving (common law), are excluded from the tables in this bulletin primarily because information on these crimes are not collected on the same basis as other motor vehicle offences. In 1997, the police recorded 35 crimes of causing death by dangerous driving, 2 crimes of causing death by careless driving when under the influence of drink or drugs and 6 crimes of reckless driving (common law). In 1997, there were 17 prosecutions where the main offence was causing death by dangerous driving, 16 of which resulted in a conviction including 14 custodial sentences. There were 4 prosecutions for causing death by careless driving while under the influence of drink or drugs, all of which resulted in a conviction including 3 custodial sentences. There were no prosecutions for reckless driving (common law) in 1997.
 
Sources of information
 
3. The statistical return from which the figures on recorded motor vehicle offences in this bulletin are taken is a simple count of the numbers of crimes and offences recorded by the police. The 8 Scottish forces are included; other police forces, such as the British Transport Police, are not. One return is made for each council area in Scotland and these are aggregated to give the national total. The return is submitted quarterly and gives the information as known at the end of each quarter. Thus amendments (such as the deletion of incidents found on investigation not to be criminal) which arise at the end of the year are not incorporated.
 
4. Most motor vehicle offences are discovered and recorded as a result of police activity rather than by being reported to the police by the public. Hence the numbers of such offences recorded are mainly determined by the strength and deployment of the police forces.
 
5. Information on the outcome of prosecutions of motor vehicle offences is mainly provided by the police forces to The Scottish Office through monthly statistical returns. Details of a relatively small number of cases also come from the police operational computer at the Scottish Criminal Record Office.
 
6. In this bulletin, statistics on court proceedings count offences proceeded against i.e. when a person is proceeded against in court for more than one charge, each charge is counted. This practice differs from that adopted in the statistical bulletins on court proceedings in which the unit of analysis is the person or company proceeded against. The year recorded in the statistics on court proceedings is the year in which the case was disposed of, e.g. if the accused was convicted in 1996 but not sentenced until 1997, the year quoted in these tables is 1997. Similarly, in some cases the year recorded in the recorded crime statistics will not be the same as the year of the court proceedings, e.g. a crime may be recorded in 1996 but the person involved may not be prosecuted, convicted and sentenced for the offence until 1997 or later. It is also possible that the offence recorded by the police may be altered as a result of the judicial proceedings, while many offences are dealt with by means other than prosecution, for example through the use of procurator or police conditional offers of fixed penalty. Statistics of court proceedings are therefore not directly comparable with the recorded crime statistics.
 
7. Disqualification from driving necessarily involved endorsement of a driving licence. However, for simplicity of presentation, the figures quoted in the bulletin for endorsement do not include disqualifications.
 
8. Information on procurator fiscal conditional offers made for motor vehicle offences are derived from summary data collected by the Crown Office from procurators fiscal. The figures for 1995, 1996 and 1997 include estimates.
 
9. Information on police conditional offers made for motor vehicle offences are based on figures provided by police force traffic departments.
 
10. Separate statistical returns to The Scottish Office are made by the police forces for the number of offences dealt with under the vehicle defect rectification scheme and the number of "stationary" offences dealt with by the issue of a fixed penalty notice by the police or traffic wardens. These are normally submitted once a year and one return is made for each police force area.
