(a) Yes. Where the cause of a fatal and serious injury traffic crash can be determined by the Attending Officer at their initial investigation into the traffic crash the cause is recorded. In the case of fatal crashes the cause may be updated at the completion of further inquiries into the traffic crash.
(b) There are 32 possible causes that are recorded in the Fatal and Serious (1-18) Details form which is the basis for the Traffic Enforcement and Crash Executive Information System (TEACEIS):
1. Alcohol
2. Alcohol/Drugs
3. Alcohol/Speed
4. Animals
5. Careless
6. Contravene TCL
7. Drugs
8. Fail to Give Way
9. Fallen Load
10. Fatigue
11. Give Way Contravened
12. Heart Attack
13. Inattention
14. Inexperience

25. Speed
26. Stop Sign
27. Traffic Calming Device
28. Travel too Close
29. Turn in Front
30. Tyre Blow Out
31. Visibility
32. Weather Conditions
(c) Western Australia Police utilises this information in a number of ways:
· The causal data combined with other characteristics of the driver, passengers, vehicle, road conditions, and weather conditions provide the data source which underpins the traffic enforcement strategies and activities undertaken by the Western Australia Police.
· This data is used at local level to determine the optimal allocation of resources and strategies and at corporate/divisional level to inform and enhance decision making about enforcement activities and prioritisation of strategies.
· The information informs the prosecution against the persons considered responsible for the traffic crash.
· This data is supplied to the Office of Road Safety to inform their decision making in relation to road safety campaigns.
· Main Roads WA uses this information to assist in their road safety data collection processes.
(d) This information is currently not available on the WA Police website. The decision on whether this information should be released is made by the Coroner.
(e) Yes. The Western Australia Police does record the cause for each fatal and serious injury crash (where the cause can be determined by the Attending Officer at their initial investigation into the traffic crash) and hence can collate crashes and the proportion of crashes by causes. The Western Australia Police does not publish data showing the proportion of traffic crashes attributed to each cause.

(f) According to the Western Australia Police 2006 fatal and serious crash data, as at 20 September 2007, the Attending Officers at their initial observations determined:
11.9 per cent of fatal and serious injuries had the cause of speed
9.8 per cent of fatal and serious injuries had the cause of alcohol/speed
30.6 per cent of fatal and serious injuries had the contributing factor of speed
It should be noted that the initial causal determination by the Attending Officer may be reviewed and amended following subsequent investigation of the crash. It should also be noted that the determination of causes is based on the judgement of Attending Officer based on the evidence and information as presented at the crash scene, and that causal factors are usually interlinked with, for example speed, carelessness, recklessness, inattention and alcohol/drugs contributing to the crash. The determination of the main causal factor is therefore a judgement based upon their interpretation of the crash scene.
