For fleet managers, HGV MOTs are an essential part of business. They keep vehicles safe, legal and productive, avoiding unexpected downtime and disruption. But there’s always that nagging doubt: what if they fail? The thing is, most MOT failures are entirely preventable. And that starts with understanding the most common reasons for MOT failure, the maintenance that can help, and the importance of regular inspections.

MOTs aren’t there to catch you out. Their role is to ensure that vehicles meet the relevant roadworthiness and safety standards. And if you run a fleet, the chances are that you’ll already understand the importance of that. Where many people go wrong isn’t in overlooking major mechanical faults, but in missing the minor defects. A worn tyre, a damaged light fitting, excessive brake wear, or a suspension issue that gradually developed over time. These are the kinds of easily correctable defects that can be so damning and costly when the MOT rolls around.
Brake-related issues are among the most common causes of HGV MOT failures, because brake components naturally wear over time. Brake pads, discs, drums, chambers and air systems all need ongoing inspection and maintenance, and even small issues can affect braking performance.
Regular brake inspections are integral to any fleet maintenance programme. Not just because it can significantly reduce the risk of MOT failure, but because it ensures the safety of your vehicles.
Tyres are another frequent source of MOT failures. Largely because they are subject to constant wear and are vulnerable to damage.
Daily vehicle checks can help drivers identify visible tyre defects before they become serious. But because wear patterns can help to highlight underlying mechanical issues, regular professional inspections are also a good idea.
Lighting faults are less likely to cause a major incident than brake failures, but they’re still a common reason for HGV MOT failure.
Bulbs can fail unexpectedly, wiring can become damaged, and electrical connections can deteriorate over time. So, it’s a good idea for routine vehicle inspections to include a full lighting check. And drivers should know to report faults as soon as they become aware of them.
Suspension is vital in all vehicles, but it’s particularly important in HGVs. But because these vehicles carry such heavy loads, components such as springs, airbags, shock absorbers, and mountings can wear far more quickly than in other vehicle types.
Suspension faults often develop gradually, so they can be easy to miss without regular inspections. Left unchecked, they can affect vehicle handling, increase tyre wear and ultimately result in MOT failure.
Steering system defects can obviously have serious safety implications in HGVs, so they play a significant role in the MOT.
Because drivers are usually the first to notice changes in steering behaviour, having an organised reporting system can save you a lot of time, stress, and money.
Visibility-related issues regularly contribute to MOT failures.
Cracked windscreens, ineffective wipers, or damaged mirrors can all lead to failure. The thing is, they’re so common that they’re also pretty easy to ignore day-to-day, so it pays to integrate an inspection into your driver’s daily routines.
General vehicle condition is also important. If any of your trucks have excessive corrosion, insecure bodywork, or damaged components, it can contribute to a failure.
One of the simplest ways to improve MOT pass rates is through daily walkaround inspections.
When every day starts or ends with an inspection, it becomes routine, and small issues can be picked up long before they become an MOT problem.
Commercial vehicle MOT prep works best when it’s an ongoing process.
A focus on preventive maintenance not only increases your chances of your fleet passing their MOTs, it can improve overall vehicle performance and reduce overall costs.
