Planned preventative maintenance for HGV fleets: why scheduled checks beat emergency callouts on the A42 and M1
How planned preventative maintenance keeps your HGV fleet compliant, on the road and earning. Serving East Midlands and South Yorkshire from Melbourne, Derby.
Why planned preventative maintenance is the backbone of a compliant HGV fleet
A truck that stops earning stops paying. Every unplanned breakdown costs you driver time, recovery fees, potential DVSA prohibition notices and, if it happens often enough, a mark against your OCRS score. Planned preventative maintenance (PPM) is the discipline that keeps those events rare rather than routine.
For operators running vehicles on the M1, A38, A50, A42 or A52, the pressure is real. These are busy, high-enforcement corridors. DVSA mobile teams operate across the East Midlands and South Yorkshire, and a vehicle that attracts attention at a check site needs to be in good shape before it gets there.
PPM is not just good housekeeping. It is a legal requirement under the operator licence system. The Traffic Commissioner expects you to maintain your vehicles in a fit and serviceable condition at all times, and a structured maintenance programme is the evidence that you are doing so.
What planned preventative maintenance actually means in practice
PPM is scheduled work carried out at fixed intervals, before faults develop rather than after they cause a failure. The intervals are based on mileage, engine hours or calendar time, whichever comes first.
For an HGV fleet, a typical PPM programme covers:
- Safety inspections (PMIs): Periodic Maintenance Inspections carried out at intervals set in your maintenance plan, usually every four to thirteen weeks depending on vehicle age, type and use. These are the formal documented checks that underpin your operator licence.
- Brake testing: Roller brake tests or decelerometer checks to verify brake performance against DVSA minimum standards. Brake fade or imbalance is one of the most common reasons vehicles are prohibited at the roadside.
- Fluid and filter services: Engine oil, coolant, AdBlue, air dryer cartridges, fuel filters. Neglecting these shortens engine life and causes avoidable breakdowns.
- Tyre inspection and replacement: Tread depth, sidewall condition, inflation, wheel fixings. Tyre-related defects account for a significant proportion of DVSA roadside prohibitions.
- Air system checks: Compressor output, air dryer function, tank drain valves, brake chambers and lines. Air system faults are a leading cause of HGV breakdowns on motorways.
- Lighting and electrical checks: All lights, indicators, ABS warning systems, tachograph calibration.
- Trailer inspection: Curtain condition and fixings, landing legs, coupling gear, brake connections, body integrity.
A good maintenance plan documents all of this, sets the intervals, records the outcomes and keeps the paperwork in order for DVSA or Traffic Commissioner scrutiny.

Common examples of preventative maintenance for trucks
People often ask for concrete examples, so here are the kinds of tasks that sit at the heart of any solid PPM programme for HGVs and trailers:
Engine and drivetrain: Oil and filter changes at manufacturer-specified intervals, coolant system inspection, fan belt condition, gearbox oil checks, clutch adjustment or wear assessment.
Braking system: Brake lining and drum/disc measurement, slack adjuster function, air line integrity, brake chamber stroke checks, roller brake test results recorded against DVSA pass thresholds.
Air system: Compressor belt condition, air dryer cartridge replacement, moisture trap draining, system pressure build-up time, leak-down testing.
Suspension: Spring and air bag condition, shock absorber function, U-bolt torque, wheel bearing checks.
Trailer: Curtain track and strap condition, body panel integrity, brake adjustment, coupling kingpin wear, running lights and ABS function.
Driver defect reporting: PPM does not start and end in the workshop. Drivers completing daily walk-around checks and reporting defects promptly is the first line of defence. Those reports feed directly into your maintenance schedule and your compliance records.
The checklist: what a PPM schedule needs to include
A PPM checklist for an HGV fleet is not a generic document. It should reflect your actual vehicle types, your routes and your operator licence undertakings. That said, every schedule needs to cover:
- Vehicle and trailer identification (reg, fleet number, VIN)
- Inspection interval and date last inspected
- Next inspection due date
- Brake performance test results
- Tyre condition and tread depth measurements
- Lights and electrical systems
- Air system function
- Steering and suspension
- Body and trailer condition
- Outstanding defects and rectification status
- Technician signature and qualifications
The completed inspection sheet is a legal document. Keep it for at least fifteen months. DVSA can request it during a roadside check or an operator compliance investigation.
What PPM costs versus what breakdowns cost
Operators sometimes look at the cost of a maintenance contract and hesitate. That is understandable. But the comparison is not "PPM cost versus nothing". It is "PPM cost versus the cost of unplanned breakdowns, DVSA prohibitions and potential licence jeopardy".
A roadside breakdown on the M1 near Nottingham or on the A50 through Derby involves recovery fees, driver downtime, possible cargo delays, and the risk of a prohibition notice if the fault is deemed a safety defect. If that prohibition leads to a DVSA targeted investigation, the costs multiply further.
The horizontravelgroup team put it plainly in their review:
"The guys here are brilliant very accommodating no job to big or small, they work fast and to a very high standard as in this business a vehicle of the road is lost money and they understand this."
That is exactly the mindset behind a proper PPM programme. Time off the road is money lost. Planned downtime for a two-hour inspection is manageable. Unplanned downtime on the hard shoulder of the A38 at midnight is not.

How we support planned preventative maintenance across East Midlands and South Yorkshire
Our workshop at Calk Mill Farm, Ashby Road, Melbourne, Derby, DE73 8BJ is open Monday to Friday, 07:30 to 17:00 for all planned work. That includes PMI safety inspections, brake testing, servicing, diagnostics and pre-MOT preparation.
We work on HGVs, trucks, trailers, vans and light commercials. We do not work on private cars. The operators who come to us are running vehicles as a business, and we treat the work accordingly.
For fleets operating across the East Midlands and South Yorkshire, including vehicles regularly on the M1, A38, A50, A42 and A52, we offer fleet maintenance contracts that take the scheduling burden off the transport manager. You know when your vehicles are due in, the paperwork is kept in order, and your inspection intervals stay inside the windows your operator licence requires.
Outside workshop hours, our emergency breakdown and recovery line is answered 24 hours a day, 365 days a year, on 01332 916028. If a vehicle fails between planned inspections, our technicians attend fully equipped and repair at the roadside wherever possible, rather than defaulting to a tow.
Frequently asked questions
What is a good example of planned preventative maintenance for an HGV?
A brake test and PMI safety inspection carried out every eight weeks on a tractor unit is a straightforward example. The vehicle comes off the road for a fixed slot, a qualified technician inspects it against a documented checklist, brake performance is tested on a roller brake tester and the results are recorded. Any defects are rectified before the vehicle returns to service. The paperwork is filed and the next inspection date is set. That cycle, repeated consistently, is what PPM looks like in practice.
What are the main types of preventive maintenance used in HGV fleet management?
The most relevant categories for HGV operators are: time-based maintenance (servicing at fixed calendar intervals), usage-based maintenance (servicing at mileage or engine-hour thresholds), condition-based maintenance (acting on inspection findings rather than fixed intervals) and predictive maintenance (using diagnostics and telematics data to anticipate failures). Most well-run fleets combine time-based and usage-based approaches as the foundation, with condition-based decisions made at each PMI.
How often should HGV safety inspections be carried out?
The DVSA guide to maintaining roadworthiness sets inspection intervals between four and thirteen weeks, depending on vehicle age, type, annual mileage and operating conditions. Older vehicles, higher-mileage operations and vehicles used on demanding routes should be inspected more frequently. Your maintenance plan must specify the interval you have chosen, and you must stick to it. Letting a vehicle run past its due date, even by a few days, is a compliance gap.
What are the recent changes to HGV brake testing requirements?
DVSA has continued to tighten its focus on brake performance, and roller brake testing is now firmly embedded in best-practice guidance for both vehicles and trailers. The key change for operators is the expectation that brake test results are recorded at every PMI, not just at MOT. If your maintenance contractor is not providing documented brake test results as part of each safety inspection, that is a gap worth addressing. Our article on brake testing for HGVs and trailers: DVSA standards and roadside checks on the A38 covers the current standards in full.
