Cause of death

Head injuries sustained in a motor vehicle incident (passenger)

AI-generated summary

A 30-year-old female passenger died from head injuries sustained in a multi-vehicle collision on the Princes Highway when a truck failed to stop in time. The collision resulted from a 'looming collision'—where the truck driver failed to detect the speed at which he was approaching stationary traffic ahead. The primary issue identified was inadequate advance warning of roadside mowing operations that had forced traffic to merge and slow unexpectedly. While the mowing operation complied with then-applicable standards, the coroner found scope for improvement in safety measures. Key clinical lesson: the investigation highlighted how human factors (poor speed perception during approach to stopped vehicles) interact with traffic management systems to create high-risk situations. No clinical interventions were involved, but the case demonstrates principles relevant to emergency medicine in understanding sudden, preventable deaths from system failures.

Error types

systemdelay

Contributing factors

  • Inadequate advance warning of roadside mowing operations and lane closure
  • Unexpected and sudden requirement for traffic to merge and slow/stop due to mobile traffic management vehicle positioning
  • Looming collision—failure of truck driver to detect closing speed relative to stationary traffic
  • Possible positioning of rear traffic management vehicle in right travel lane rather than on shoulder, removing advance warning buffer
  • Lack of static pre-warning signs prior to mobile traffic management vehicles
  • High-speed arterial road environment with limited sightlines due to road crest
  • Collision during peak hour traffic period

Coroner's recommendations

  1. That the Department of Transport and Planning in conjunction with Fulton Hogan limit hours for conducting slashing/mowing operations to avoid daily peak hour period(s)
  2. That the Department of Transport and Planning in conjunction with Fulton Hogan mandate the use of a single electronic variable messaging sign on all Category 3 routes in Victoria
