Fewer major truck incidents are being attributed to inattention and distraction, but the improvement comes with a warning for fleet operators: losing focus remains the largest individual contributor in the latest NTARC analysis.
The 2026 National Truck Accident Research Centre Major Incident Investigation Report found the inattention/distraction incident rate fell to 17.0 per 10,000 NTI-insured heavy vehicles in 2025, down from 25.4 in 2023.
That represents a 33.1% reduction over two years. Even so, the category accounted for 13.8% of all major incidents in 2025.
The decline is encouraging. What the research cannot establish is which changes in technology, training or operating practices produced it.
For fleet managers, the findings support continued attention to the demands placed on drivers, including those originating inside their own organisation.
More than a mobile phone problem
NTARC groups inattention and distraction together, but they describe different ways a driver can become disengaged from driving.
Distraction involves a competing stimulus drawing attention away from the task. Inattention involves a loss of mental focus, such as daydreaming or cognitive wandering.
The report discusses mobile phones, console displays, eating and drinking as examples of potential distractions. It also identifies additional demands within heavy vehicle cabins, including route-planning systems and electronic work diaries.
This creates a practical challenge. Equipment intended to support a driver’s work can also compete for attention if it requires interaction at the wrong moment.
The implications extend to dispatch calls, job updates and other communications. A review of distraction risk should consider how and when drivers receive information, as well as the rules governing their response.
For an operator, a useful question is whether routine work processes allow drivers to deal with non-driving tasks while safely stopped.
Many incidents involve no other vehicle
Some 63.5% of inattention/distraction crashes in 2025 involved only the insured heavy vehicle.
That finding broadens the discussion beyond distraction in busy traffic. A lapse in attention can have consequences even when there is no nearby vehicle demanding an immediate response.
The report’s crash classifications also show a range of outcomes and movements associated with inattention and distraction, including vehicles leaving straight sections of road and crashes involving vehicles travelling in the same direction.
There is no single incident pattern for fleets to monitor. The risk can emerge across different driving environments and tasks.
Regional roads feature prominently
Inner and outer regional areas accounted for 53% of inattention/distraction incidents, compared with 47.9% of major incidents overall.
The report suggests longer travel distances, reduced visual stimuli or complacency on less-trafficked roads may help explain the regional pattern. These are possible explanations rather than causes demonstrated by the analysis.
Urban operations present a different attention challenge. Rigid truck and bus/coach inattention/distraction incidents were more commonly associated with major cities, where frequent stops and interactions with other road users can increase the demands on a driver.
Together, these findings suggest that managing attention requires an understanding of the work being performed. A regional freight journey and an urban delivery run place different demands on the person behind the wheel.
Improvement needs careful interpretation
The report describes the declining incident rate as a positive development, while noting that inattention and distraction remain a significant safety concern.
Its authors also flag changes to NTI’s data collection and validation during 2025–2026, which may introduce inconsistencies in categorisation compared with previous years.
The analysis covers NTI-insured major loss incidents exceeding $50,000. It is not a measure of every Australian truck crash, and the broader dataset includes non-crash losses such as theft, fire and flood.
Each incident is assigned a single dominant cause code. That approach helps identify patterns, but it can overlook the combination of circumstances leading to an event.
Keep the focus on everyday operations
For fleet managers, the downward trend provides a reason to examine what is working within their own operation and where gaps remain.
That could include reviewing communication practices, how drivers interact with navigation and work systems, and whether incident investigations explore the circumstances behind a loss of attention.
Driver coaching can also benefit from distinguishing between an identifiable distraction and a broader lapse in concentration. The response may differ depending on what happened.
The report does not prove that any particular intervention caused the improvement. It does show that, despite the decline, inattention and distraction remain a substantial contributor to major incidents.
Maintaining progress will require fleets to keep examining the everyday tasks, messages and working conditions that shape a driver’s ability to concentrate.
