1. Crash statistics
Our statistics are confined to crashes that conform to the national guidelines for reporting and classifying road vehicle crashes. The guidelines include crashes that meet all of these criteria:
- Were reported to the police
- Occurred on a road open to the public
- Involved at least one moving road vehicle
- Involved at least one person being killed or injured or at least one motor vehicle being towed away.
Reports for some crashes are not received until well into the following year and after the annual crash database has been finalised. These amount to fewer than 1 per cent of recorded crashes and are counted in the following year's statistics.
Before 2000, Section 8 (3) of the Traffic Act 1909 required a road crash in NSW to be reported to the police when any person was killed or injured, or there was property damage of more than $500.
On 1 December 1999, the Traffic Act was repealed and replaced by new traffic legislation including the adoption of the Australian Road Rules. The new traffic legislation is found in the Road Transport (General) Act 1999 and the Road Transport (Safety and Traffic Management) Act 1999 and the regulations made under those Acts.
Rule 287 (3) of the Road Rules requires a crash to be reported to police when any person is killed or injured; when drivers involved in the crash do not exchange particulars; or when a vehicle involved in the crash is towed away.
2. Interactive crash statistics
Date of crash
Data presented in these displays is based on the ‘reporting year’ of the crash to police.
Road User data
In some displays the Road User values ‘Other Controller’ (e.g horse riders) and ‘Other Passenger’ (e.g train or light rail passenger) have been suppressed. However, the Grand Total will include these values.
Pedal cycle crashes
There are two means for which pedal cycle crashes are identified and included in the CRS crash database. The first is where pedal cycle crashes are reported to NSW Police. The injury severity of the pedal cyclists involved is determined by the regular linkage of these records with NSW Ministry of Health data collections. A pedal cyclist record linked to a hospital stay is classified as a ‘matched serious injury’. Many pedal cyclists admitted to a hospital are for various reasons unable to be linked to a police report. This second process of identification results in a cohort of seriously injured pedal cyclists classified as ‘unmatched serious injuries’. Interactive crash statistic displays that only use matched serious injuries will therefore under report the extent of road trauma involving pedal cyclists.
3. Definitions and notes

- High Threat to Life Indicator (HTTL)
- An alternative dimension of severity based on a person’s probability of survival. This metric is based on a person’s worst injury where the lowest SRR (Survival Risk Ratio) of all diagnosis codes for the first admission is used to calculate ICISS (ICD-based Injury Severity Score). ICISS values are banded into two categories and have the following survival probabilities:
Yes - at most 94.1%
No – at least 94.1%
- Injury severity category
- A dimension of severity based on a person’s probability of survival. This metric is based on a person’s worst injury where the lowest SRR (Survival Risk Ratio) of all diagnosis codes for the first admission is used to calculate ICISS (ICD-based Injury Severity Score). ICISS values are banded into four categories and have the following survival probabilities:
Maximum severity - at most 85.4%
High severity - between 85.4% and 96.5%
Moderate severity - between 96.5% and 99.2%
Minimum severity - at least 99.2%

It is not always clear from police reports if speeding (excessive speed for the prevailing conditions) was a contributing factor in a road crash. We consider speeding to have been a contributing factor if at least one speeding motor vehicle was in a crash. We say a motor vehicle was speeding if it meets any of these conditions:
- Police said the vehicle was travelling at excessive speed
- The speed of the vehicle was faster than that allowed for the licence class of the driver or rider, or the vehicle weight (introduced 1 January 2010)
- The speed of the vehicle was higher than the speed limit
- While on a curve the vehicle jack-knifed, skidded, slid or the controller lost control
- The vehicle ran off the road on a bend or turning a corner and the driver or rider was not distracted by something, or affected by drowsiness or sudden illness, and was not swerving to avoid another vehicle, animal or object, and the vehicle did not have equipment failure
It is not always clear from police reports if fatigue was a contributing factor in a road crash. We consider fatigue to have been a contributing factor if at least one fatigued motor vehicle controller was in a road crash. We define a motor vehicle controller to be fatigued if they meet any of these conditions:
- Police said the motor vehicle driver or rider was asleep, drowsy or tired
- The vehicle travelled onto the incorrect side of a straight road and had a head-on collision (and was not overtaking another vehicle and no other relevant factor was found)
- The vehicle ran off a straight road or off the road to the outside of a curve and the vehicle was not travelling at excessive speed and there was no other relevant factor found for the crash
