Heavy vehicle distraction risk is often discussed as a mobile phone problem in the cab, but that framing is too narrow for modern operations. Across many fleets, in-trip distraction is created upstream by the way work is planned, supervised and adjusted. Messages arrive while a driver is navigating a metro delivery run. Calls are made to chase ETA updates when schedules are already tight. New pickup instructions are issued on the move without a safe process for acknowledging and acting on them. Under the HVNL, that broader operating context matters.
The Chain of Responsibility does not stop at the driver’s hands on the wheel. If a scheduler, supervisor, consignor or operator creates work practices that pressure immediate responses, they may be contributing to unsafe conduct. The legal question is not simply whether a driver touched a device. It is whether each party took all reasonably practicable steps to eliminate or minimise the risk that distraction would arise in the first place.
This is particularly relevant in mixed fleets using telematics, routing apps, proof-of-delivery tools and customer messaging platforms. Technology can improve compliance, but it can also multiply touchpoints during the trip. A system that sends constant exceptions, route changes or service alerts may be operationally efficient in theory while creating unacceptable risk in practice. If the only safeguard is “the driver knows not to check it”, the control framework is weak.
NHVR attention in this area is likely to focus on decision-making evidence. Investigators and auditors will want to understand who can contact drivers while a vehicle is moving, what kinds of issues justify contact, whether non-urgent matters are held until a safe stop, and how dispatch teams are trained. They will also look at whether KPIs indirectly reward immediate responses, rapid turnarounds or constant location updates.
Operators should start by mapping every communication pathway into the cab. Include phones, apps, in-vehicle devices, customer portals and informal messaging channels. Then classify messages by urgency. Safety-critical communication needs a clear protocol. Routine operational updates should be delayed until the next planned stop. If route changes are common, build a standard process requiring the vehicle to be stationary before the instruction is read, confirmed and implemented.
It is also worth reviewing after-hours escalation and missed-delivery workflows. Some of the worst distraction pressure appears late in a shift, when fatigue and time pressure are already present. A calm, documented exception process reduces the temptation to improvise.
Finally, train office staff as seriously as drivers. Many distraction risks are generated by people who never enter the vehicle. They need to understand how their actions can create HVNL exposure for the business and for themselves.
If your business needs practical help turning communication risk into clear CoR controls, COR’s CoR training programs can lift capability across operations, scheduling and management teams.
