Road crash analysis
We collate and provide road crash statistics using data from NSW Health, the State Insurance Regulatory Authority (SIRA), icare (Insurance & Care NSW) and the NSW Police Force. Each day, we process and review road crash data to gain information on deaths and serious injuries for every crash. We monitor and report fatal crashes in the:
- NSW Road Toll - Daily (PDF, 489.43 KB)
- NSW Road Toll-Monthly (PDF, 491.98 KB)
- NSW Heavy Truck Fatal Crashes (PDF, 403.83 KB)
Our crash database, CrashLink, is used for road safety analysis and research work, strategic planning and policy development. Our road crash data is used by the public and organisations such as the Federal Bureau of Infrastructure, Transport and Regional Economics, NSW Police Force, NRMA Motoring & Services, Australian Bureau of Statistics, local governments, road safety researchers and community groups.
The NSW Road Toll Progress Report (PDF, 789.1 KB) shows preliminary provisional data as at 1 January 2023.
The NSW Road Traffic Casualty Crashes 2021 (PDF, 3.62 MB) provides a comprehensive statistical statement for the year ended 31 December 2021.
How to use this information
Our statistics are confined to crashes that meet 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 aren't received until well into the following year and after the annual crash database has been finalised. These amount to fewer than 1% of recorded crashes and are counted in the following year's statistics.
Before 2000, under Section 8 (3) of the Traffic Act 1909, road crashes in NSW had 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On 1 December 1999, the Traffic Act was repealed and replaced by new traffic legislation including the adoption of the Australian Road Rules.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.
Under Rule 287 (3) of the Road Rules, a crash must be reported to police when any person is killed or injured, when drivers involved in the crash don't exchange particulars, or when a vehicle involved in the crash is towed away.

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 2 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 4 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%

Seriously injured (matched)
A person identified in the police crash report data (casualty or traffic unit controller) matched to a hospital stay that isn't an ED-only admission (unless that ended in a transfer interstate, to private hospital or other medical facility) containing an injury diagnosis on the same day or the day after a crash and did not die within 30 days of the crash or linked to a Lifetime Care participant record.
Seriously injured (unmatched)

Speeding and fatigue involvement
It's 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 motor vehicle in a crash was speeding. 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 wasn't distracted by something, or affected by drowsiness or sudden illness, and wasn't swerving to avoid another vehicle, animal or object, and the vehicle didn't have equipment failure.
It's not always clear from police reports if fatigue is a contributing factor in a road crash. We consider fatigue to have been a contributing factor if at least one motor vehicle controller in a road crash was fatigued. We say a motor vehicle controller was 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 wasn't 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 wasn't travelling at excessive speed and there was no other relevant factor found for the crash.
