AI-generated summary

Three men died in a single-vehicle motor vehicle crash in Western Australia on 15 October 2012. All three were significantly intoxicated with methylamphetamine and other drugs at the time of the crash. The driver (Arjomand) suffered a fatal head injury consistent with loss of consciousness or sudden sleep due to stimulant intoxication. The two passengers sustained serious chest, abdominal and internal injuries. Toxicological evidence confirmed high levels of methylamphetamine in all three, which impairs judgment, increases risk-taking behaviour, and renders users vulnerable to sudden cardiac events and unconsciousness. The coroner found all three deaths were accidental and attributable to injuries sustained in the crash, exacerbated by drug intoxication. This case illustrates how stimulant intoxication significantly impairs driving ability and reduces physiological reserves to survive trauma.

Contributing factors

  • Driver intoxicated with high levels of methylamphetamine and MDMA affecting judgment, risk-taking behaviour, and consciousness
  • Methamphetamine intoxication causes defective vehicle control, impaired reactions, sudden sleep, and failure to recognise hazards
  • All three occupants intoxicated with stimulants at significant levels
  • Methylamphetamine intoxication reduces physiological capacity to compensate for trauma and blood loss
  • High-speed motor vehicle crash into tree
  • Driver failure to respond to road conditions (gentle left bend), indicating unconsciousness or sleep
  • No evidence of vehicle defects or other vehicles involved
  • Severe internal injuries not immediately obvious externally in passengers
