The Overlooked Risk
Construction businesses invest heavily in site safety — toolbox talks, harness checks, scaffold inspections, asbestos management plans. The journey to and from site often receives far less structured attention. But road accidents happen daily in New Zealand, and for businesses with operational vehicle fleets — utes, vans, flatbeds, heavy transport — the risk profile is significant. Multiple parties share safety responsibility: drivers, vehicle technicians, dispatchers, and management all have roles in the outcome.
Driver Fatigue: The Time Limit That Matters
Industry guidance recommends that staff should not exceed 13 hours of total driving per day — and shorter driving periods are preferable for sustained performance. Long driving periods contribute to drowsiness and inattention, which are major factors in serious vehicle accidents. For construction workers starting early, working full days on site, and then driving home in the evening, the cumulative fatigue picture requires active management rather than assuming drivers will self-limit when tired.
Practical management approaches include rostering that accounts for total daily hours including driving time, providing overnight accommodation for distant sites where driving home after a long shift creates unacceptable fatigue risk, and establishing a genuine culture where workers feel able to say they are too tired to drive safely without career consequences.
Technology That Reduces Risk
Modern fleet management technology provides tools that were not available to previous generations of contracting businesses:
- Collision warning systems: forward-collision alerts that give drivers additional reaction time
- Lane departure warnings: detecting driver inattention before it results in a lane-change incident
- Speed monitoring: real-time and trip-summary data allowing managers to identify speed compliance issues before an incident occurs
- In-vehicle cameras: providing objective evidence in accident investigations and creating driver accountability
- Adaptive cruise control: maintaining safe following distances in highway driving
The return on investment for these technologies is measurable in reduced accident frequency, lower insurance premiums, and reduced at-fault liability exposure. The implementation conversation with staff should be framed around safety rather than surveillance — the data is most valuable for identifying systemic issues, not for disciplining individual drivers.
Regular Servicing as Risk Management
Vehicle servicing is not merely a compliance obligation — it is a risk management activity. Regular servicing detects mechanical issues early (brake wear, tyre condition, suspension faults) before they produce vehicle failures that contribute to accidents. A planned servicing programme is also operationally efficient: scheduled maintenance at known intervals is far less disruptive than unplanned breakdowns, and far less costly than the downtime, repair bills, and accident consequences that follow from deferred maintenance.
Building vehicle servicing records into your health and safety documentation — as evidence that vehicles are being maintained to manufacturer specifications — is also important if your business is ever subject to WorkSafe scrutiny following a vehicle-related incident.
