Transport managers new to the role often conflate the daily walkaround check with the Preventative Maintenance Inspection (PMI). They are two distinct activities with different purposes, performed by different people on very different intervals. Getting the distinction right matters, because DVSA expects to see both as part of a properly run maintenance system.
The daily walkaround check
The walkaround is the driver's responsibility. It happens before the vehicle is first used each day and is a visual, functional safety check — tyres, lights, brakes, mirrors, leaks, load security and so on. It needs no workshop, no ramp and no specialist tools. Its job is to catch obvious roadworthiness problems before the vehicle leaves the yard, and to give the driver a clear basis for refusing to drive something unsafe.
Because it happens daily and on every vehicle in use, the walkaround is the most frequent compliance touchpoint a fleet has. The record it produces — including a nil-defect confirmation when nothing is wrong — is the day-to-day evidence that roadworthiness is being checked.
The Preventative Maintenance Inspection (PMI)
The PMI (also called a safety inspection) is a thorough, workshop-based inspection carried out by a competent person — usually a qualified technician — against a documented inspection sheet. It covers the safety-critical systems in depth: brake performance, steering, suspension, the structure, and the many items DVSA lists in its inspection manual. It is the planned, preventative half of the system, designed to find wear and developing faults before they become defects.
PMIs run on a planned interval set out in your maintenance schedule. The interval depends on the type of vehicle, how it is used and how hard it works — high-mileage or arduous operations need more frequent inspections. The interval you commit to is part of your O-licence undertakings, so it should be realistic and consistently met. A common arrangement is a fixed time-based interval (for example, every few weeks), but the right figure is the one you can justify for your operation and actually keep to.
How they fit together
Think of the two as a layered system. The walkaround is the wide, shallow daily net; the PMI is the deep, periodic inspection. They reinforce each other in both directions:
- A walkaround defect that keeps recurring is a signal that something needs investigating at the next PMI — or sooner.
- A PMI is the moment to review the walkaround defect history for that vehicle and look for patterns.
- Neither replaces the other: a recent PMI does not excuse a missed walkaround, and a clean walkaround does not extend a PMI interval.
- Both feed the same goal — a continuously roadworthy vehicle and a paper trail that proves it.
What this means for your records
When DVSA reviews your maintenance system, it looks at whether the two activities are happening, are recorded, and join up. Walkaround records show the daily checks; PMI sheets show the planned inspections; and defect reports show what was found and how it was put right. A fleet that can lay those three streams side by side, for any vehicle, on any date, is demonstrating exactly the kind of effective maintenance system the O-licence requires.
