Automated Truck Inspections and Connected Trailers Technology

For fleet managers, visibility is only part of the equation. While vehicle tracking reveals where trucks and trailers are, automated truck inspections and connected trailers technology reveal how they are actually performing.

Combined, these capabilities offer major advantages for fleets, particularly in Australia, where vehicles operate across vast distances, remote areas, and challenging environments, and where a roadworthiness issue can surface hundreds of kilometres from the nearest depot or service point. This guide explores what they are, how they work, and why they're essential.

What are automated truck inspections?

Automated truck inspections use digital tools and vehicle-integrated sensors to monitor roadworthiness in real time, so (as opposed to relying solely on manual walkaround checks) managers get continuous insight into integral components such as brakes, tyres, lights, load security, and trailer coupling status.

Inspection data is automatically captured and sent to a central platform, allowing fleet managers to identify faults instantly, receive alerts, and schedule preventative maintenance before minor issues become more costly breakdowns. By digitising inspections, fleets reduce paperwork, remove guesswork, and maintain a consistent standard of safety across the operation.

How do automated truck inspections work?

Automated inspections combine onboard sensors, telematics devices, and fleet management software into a system that collects live data, including brake temperature and performance, axle loads (measured in tonnes), tyre pressure, and mechanical fault codes.

For instance, electronic brake performance monitoring systems (EBPMS) assess braking efficiency, while tyre pressure monitoring systems (TPMS) track pressure and temperature to maintain safe operating conditions. On-board mass sensors can monitor axle group loads, which is particularly useful in Australia where staying within mass limits is both a safety and a compliance matter. If a reading drops below, or climbs above, a predefined threshold, the system triggers an alert.

All data is transmitted via secure connectivity to a central dashboard, where fleet managers can view vehicle status in real time, generate compliance reports, and track maintenance history. The result is a streamlined inspection process that heightens both safety and operational efficiency.

Why are automated inspections important for compliance?

Compliance with Australian heavy vehicle regulation is non-negotiable, and this is where automated inspections carry particular weight. Under the Heavy Vehicle National Law (HVNL), administered by the National Heavy Vehicle Regulator (NHVR) for vehicles over 4.5 tonnes, keeping vehicles roadworthy is a core duty, and the Chain of Responsibility (CoR) provisions extend that duty beyond the driver to operators, schedulers, and others who influence a transport activity.

Automated inspections support these obligations by ensuring critical safety components are monitored constantly rather than checked intermittently. Two points are worth drawing out for Australian operators:

• Documented daily checks and maintenance records. A documented daily roadworthiness check and a record of maintenance activity sit at the heart of demonstrating due diligence. Under the Maintenance Management module of the National Heavy Vehicle Accreditation Scheme (NHVAS), these are formal requirements, and accreditation can exempt vehicles from annual inspections in some jurisdictions such as New South Wales and Queensland. Automated inspections generate exactly this kind of consistent, time-stamped record across both trucks and trailers, with far less administrative effort than paper checklists.
  
  
• A shift towards demonstrable, documented compliance. The reformed HVNL commences on 1 August 2026, leaning further towards a risk-based approach in which operators are expected to evidence the reasonable steps they have taken through documented systems. From the same date, the NHVAS is progressively replaced by the new Heavy Vehicle Accreditation (HVA) scheme. In both cases, reliable telematics and digital inspection records are a practical way to show that vehicles are being monitored and maintained.

Digital inspection records create clear audit trails that make it easier to demonstrate this due diligence. Alerts for issues such as brake imbalance, tyre underinflation, or overloading let managers act immediately, reducing the risk of penalties while protecting drivers, cargo, and reputation, and providing the kind of evidence that matters if a vehicle is intercepted for a roadside inspection.

What is connected trailers technology?

Connected trailers technology extends visibility beyond the prime mover to include the trailer itself. Through integrated GPS tracking, sensor connectivity, and telematics, each trailer becomes an intelligent asset within a wider fleet ecosystem.

Working similarly to truck tracking, this technology provides real-time insight into trailer location, load status, brake performance, tyre condition, and coupling information. Fleet managers can instantly see which trailer is attached to which vehicle, whether it is loaded or empty, and whether it is operating within safe parameters. This matters all the more for the multi-trailer combinations common on Australian routes, such as B-doubles and road trains, where each unit needs to be accounted for individually rather than treated as a single asset.

How do connected trailers improve safety and efficiency?

Safety improvements are a direct result of continuous monitoring. TPMS keeps tyre pressure at optimal levels to reduce blowout risk and improve fuel efficiency on long-haul journeys, which is significant given the heat and sustained distances Australian tyres endure. EBPMS, meanwhile, helps ensure braking systems operate as intended, reducing the likelihood of incidents such as brake fires on long descents.

Efficiency is primarily improved through better asset utilisation: real-time visibility of loaded and empty trailers means managers can reduce unnecessary journeys and optimise dispatching, a meaningful saving over the long distances typical of Australian freight. Geofencing capabilities trigger notifications if a trailer moves or operates outside authorised zones or hours, strengthening security and guarding against theft. And early fault detection reduces downtime, because preventative maintenance alerts enable intervention before a breakdown disrupts schedules, an outcome that is far more costly when it happens on a remote stretch.

Can automated inspections and connected trailers work together?

Yes. Automated truck inspections integrate naturally with connected trailers technology. Vehicle diagnostics, trailer brake data, tyre performance, load and mass monitoring, and GPS tracking can all be viewed within a single, intuitive dashboard, making sure inspection data aligns with driver hours, route planning, and maintenance scheduling. For an operator running combinations across multiple jurisdictions, that unified record is also a single, consistent source of compliance evidence.

This unification simplifies reporting, improves decision-making, and reduces administrative workload. Despite the initial investment, automated inspections and connected trailers deliver measurable long-term savings.

At MICHELIN Connected Fleet, we recognise that automation and connectivity are no longer optional. They are fundamental to cost control, risk reduction, and optimised performance, which is why they are built into our fleet management solutions, with hardware designed to keep performing in demanding Australian conditions.
