In South Africa, where fleets operate across long distances, remote areas, and cross-border routes, maintaining continuous visibility over vehicles is essential. But 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.

Together, these capabilities deliver a whole host of benefits for fleets, and in this guide we'll explain what exactly they are, how they work, and why you need them.

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 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.

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 performance, axle loads, 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 especially useful in South Africa where overloading is closely policed at weighbridges, since it lets operators confirm a load is within legal limits before reaching one. If a reading moves outside 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. In remote areas with limited network coverage, data can be stored locally and transmitted once connectivity is restored, ensuring no loss of critical inspection information. The result is a streamlined inspection process that heightens both safety and operational efficiency.

Why are automated inspections important for compliance?

Compliance with regulations set by the Department of Transport and enforced by the Road Traffic Management Corporation (RTMC) is non-negotiable for heavy commercial fleets, and this is where automated inspections carry particular weight. Vehicles must be kept roadworthy under the National Road Traffic Act, and automated inspections support this by ensuring critical safety components are monitored constantly rather than checked intermittently.

Two areas stand out for South African operators:

  • RTMS accreditation. The Road Transport Management System (RTMS) is a voluntary, industry-led and government-supported self-regulation scheme, based on the SANS 1395 standard and audited by SANAS-accredited certification bodies. Several of its requirements, including daily roadworthy verification, a preventive maintenance process, and tyre management, map almost exactly onto what automated inspections produce. Consistent, time-stamped digital records across both trucks and trailers provide much of the evidence an operator needs to gain and keep RTMS certification, with far less administrative effort than paper checklists, and a recognised RTMS status can support more favourable insurance terms.

  • Overloading and load control. Overloading is a persistent problem on South African roads and the focus of the Department of Transport's National Overload Control Strategy. On-board mass data helps operators stay within legal limits, while clear loading records support the consignor and consignee obligations set out in the National Road Traffic Act. This protects road infrastructure, reduces wear on vehicles, and lowers the risk of penalties.

Digital inspection records create clear audit trails that make it easier to demonstrate 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. This is particularly valuable in an environment where roadside inspections and weighbridge checks are common, and where being able to show a documented record can make the difference.

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. That visibility is especially valuable on the long-haul and cross-border corridors common to South African freight, where a trailer may be out of sight for days at a time.

How do connected trailers improve safety and efficiency?

Safety improvements are a direct result of continuous monitoring. TPMS maintains optimal tyre pressure, reducing blowout risk and improving fuel efficiency, which matters given the heat and sustained distances South African tyres endure. EBPMS, meanwhile, helps ensure braking systems perform as intended, lowering the likelihood of incidents on the long descents and variable road surfaces found on many routes.

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. Geofencing capabilities trigger notifications if a trailer moves or operates outside authorised zones or hours, strengthening security and helping guard against theft, a serious concern in a market where cargo crime remains high. 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 far from the nearest depot.

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 RTMS-accredited operator, that unified record also serves as a single, consistent source of compliance evidence.

These technologies are widely used across industries such as logistics, mining, construction, and agriculture, where vehicle reliability and compliance are critical to operations. 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 essential for controlling costs, reducing risk, and optimising performance, which is why they are built into our fleet management solutions, with hardware designed to keep performing in demanding South African conditions.
