Crash investigation

The Crash Investigation Unit (CIU), formerly known as the Accident Investigation Squad (AIS), is a specialised division within the police force responsible for examining serious road collisions resulting in severe injury or death. Their investigations often reveal that many crashes are not mere accidents but are caused by specific actions or negligence, such as distracted driving, speeding, or disobeying traffic signals. The CIU handles offenses including manslaughter and various degrees of dangerous driving causing death or grievous bodily harm, with penalties ranging from seven to twenty-five years of imprisonment. Convictions for these offenses lead to criminal records, significantly impacting an individual’s freedom and future opportunities.

Common causes of injury and fatal crashes investigated by the CIU include fatigue, drink driving, speeding, and inattention. Fatigue contributes to nearly 20% of annual road fatalities in New South Wales, with symptoms like poor concentration and micro-sleeps leading to devastating consequences. Alcohol impairs brain function, reducing reaction times and judgment, thereby increasing crash risk. Speeding diminishes the time available to respond to hazards and escalates the severity of collisions. Inattention, whether due to mobile phone use, interactions with passengers, or other distractions, often results in crashes occurring within moments of diverted focus.

The CIU emphasises that driver negligence remains a leading factor in fatal crashes. Seemingly minor actions, such as adjusting the radio or momentarily glancing at a phone, can have catastrophic outcomes. The consequences of negligent driving extend beyond legal penalties, encompassing personal injury, emotional distress, loss of life, and broader societal impacts like increased healthcare costs and emergency service utilization. The CIU urges drivers to consider the far-reaching effects of their actions, advocating for responsible driving behaviours to enhance road safety for all.
