Preventative Maintenance Inspections: What HGV and Bus Operators Must Record

There's a persistent misunderstanding among smaller commercial operators: that passing the annual roadworthiness test means the vehicle is compliant for the year. It doesn't. The test is a snapshot on one day. The legal obligation is to present a roadworthy vehicle every day it's on the road, and to be able to show how you make sure of that.

That's what the preventative maintenance inspection (PMI) regime is for.

The three layers of a maintenance system

A defensible roadworthiness system for HGVs and buses has three distinct parts, and operators most often fall down on the first:

1. Daily walkaround checks: the driver inspects the vehicle before first use, records the result, and reports defects. Crucially, "nil defect" results should be recorded too, so you can show the check actually happened
2. Periodic safety inspections: scheduled inspections at defined intervals by a competent person, against a documented inspection sheet covering the full safety-critical system of the vehicle
3. Annual roadworthiness test: the CVRT, which the first two layers should make a formality

Inspection intervals

Safety inspection frequency is set by the operator based on the vehicle's age, mileage, type of work and operating conditions, and is declared as part of your maintenance arrangements. Many operators work to a fixed cycle, commonly around a 12-week interval for typical operations, and shorter for high-mileage or arduous work. The interval you declare is the interval you're expected to keep to.

What a proper inspection record contains

An inspection sheet should be specific enough that someone reading it two years later can see exactly what was checked and what was found:

• Vehicle registration, date, and odometer reading
• Name and signature of the inspector
• Every item inspected, with a clear pass, fail or advisory result, not a single tick at the bottom
• Brake performance assessment
• Defects identified, the repair carried out, and the date completed
• A signed declaration that the vehicle is roadworthy following the work

An inspection sheet with defects listed but no record of the repair is arguably worse than no sheet at all. It's documented evidence that you knew about a fault and put the vehicle back on the road anyway.

How long to keep records

Under SI 348 of 2013, daily walkaround check records must be retained for two years. Authorised officers also expect the original documentation relating to maintenance and repairs to be retained and produced on request, at an audit or at the roadside. Daily defect reports, inspection sheets, repair invoices and brake test results all form part of the picture. Store them so they can be found by vehicle and by date. A box of loose paper in the workshop doesn't count as a system.

The driver defect reporting loop

The part that most often breaks is the loop, not the check. A driver reports a defect, and then: who saw it, who decided whether it was safety-critical, who authorised the vehicle to continue, who booked the repair, and who signed it off? If you can't answer that chain for a specific defect from six months ago, the process isn't working, however diligent the drivers are.

Why the assignment record matters here too

Defect reporting and driver accountability are the same record viewed from two angles. If a defect is reported on a Tuesday and the vehicle was in three different hands that week, you need to know who had it and when, both to follow up properly and to answer questions later. Keeping a timestamped record of which driver held which vehicle turns that into a lookup rather than an investigation.

Keeping it manageable for a small fleet

Large operators run this on dedicated fleet maintenance systems. Small operators usually run it on a wall planner and good intentions, which works right up until the week everything happens at once. The minimum viable system is: a known next-due date for every vehicle's safety inspection, a reminder that reaches you before it lapses, and a place where the inspection and repair history lives per vehicle.

FleetMain tracks each vehicle's next safety inspection due date alongside CVRT, motor tax, insurance, operator licence and tachograph calibration, and emails reminders at 30, 14 and 7 days. Service records attach to the individual vehicle with date, description, cost and mileage, so the maintenance history stays with the van rather than in a folder somewhere.
