Crash Investigation

In cooperation with local governments, we conduct crash location investigations after the occurrence of a fatal or serious casualty crash.

The primary focus of crash investigations is to identify road environment factors which may possibly be related to the cause of a crash or may have increased the severity of a crash.

Crash investigations are undertaken using a two stage process;

  • Preliminary Crash Investigations which should occur within 7 working days of the crash; and
  • Detailed Crash Investigations which are completed only if a road environment factor possibly related to the cause or severity of a crash is identified in the preliminary crash investigation.
