What a safety inspection covers
A safety inspection, or PMI, is a systematic check to the DVSA inspection manual covering brakes, steering, suspension, tyres, lights, chassis and coupling, with a measured brake test. Every listed item must be assessed and marked, defects rectified, and the sheet signed by a competent person.
The safety inspection - often called the PMI (preventive maintenance inspection) - is the scheduled, systematic check that sits at the heart of the maintenance system. Getting the frequency right is only half the job; the inspection itself has to be thorough, competent and evidenced.
Inspected to a recognised standard
A proper safety inspection follows a recognised standard - the DVSA HGV or trailer inspection manuals - so nothing is left to memory. The inspection sheet lists the items to check, each tied to the manual's IM (Inspection Manual) numbering, covering the whole vehicle:
- Brakes, including a measured brake performance test
- Steering and suspension
- Tyres, wheels and wheel security
- Lights, indicators, markings and reflectors
- Cab, mirrors, glass and driver's view
- Chassis, body and, on a combination, the coupling and trailer
- Exhaust, emissions and driveline
- Security of load-carrying equipment
Every item assessed, defects rectified
A safety inspection is only worth anything if every listed item is assessed and marked, defects are recorded, and anything affecting roadworthiness is put right - and re-checked - before the vehicle goes back into service. A sheet with blanks, or one where defects were noted but never closed out, is worse than useless in a DVSA investigation: it proves the system does not work.
A road test where needed
Where the inspection or the vehicle's condition calls for it, a road test checks the things a static inspection cannot - brake feel, steering, noises, warning lights under load. It is recorded like everything else.
Signed by a competent person
The inspection must be carried out and signed off by someone competent to do it, whether that is your own fitter or a contracted workshop. If you contract it out, you remain responsible: you must still receive, review and keep the records, and chase any defect through to repair.
Tick-box vs real
The difference between an inspection that protects your licence and one that endangers it is visible on the sheet: real assessments against each item, a genuine laden brake test with its printout, defects with rectification recorded, a competent signature, and a clean chain to the driver's daily checks. Examiners can tell the difference in seconds.
How OperatorCompliance helps
OperatorCompliance carries a full VC60-style electronic inspection sheet: a linked workshop completes every item, records the brake readings, uploads the roller printout, and the finished inspection is stored against the vehicle and fed into the compliance record and planner. Nothing is left blank, and nothing is left in a drawer. See how it works or start a free 14-day trial.

Frequently asked questions
What is a safety inspection (PMI)?
A safety inspection, often called a PMI or preventive maintenance inspection, is the scheduled, systematic check at the heart of the maintenance system. It follows a recognised standard, the DVSA HGV or trailer inspection manuals, so nothing is left to memory, and it covers the whole vehicle from brakes and steering to lights, chassis and, on a combination, the coupling.
What does a safety inspection cover?
Brakes including a measured brake performance test, steering and suspension, tyres, wheels and wheel security, lights, indicators, markings and reflectors, cab, mirrors, glass and driver's view, chassis, body and coupling, exhaust, emissions and driveline, and the security of load-carrying equipment. Every listed item is assessed and marked against the inspection manual's numbering.
Who can carry out a safety inspection?
The inspection must be carried out and signed off by someone competent to do it, whether that is your own fitter or a contracted workshop. If you contract it out, you remain responsible: you must still receive, review and keep the records, and chase any defect through to repair. A road test is added where the inspection or the vehicle's condition calls for it.
What makes a safety inspection stand up to scrutiny?
Every listed item assessed and marked, a genuine laden brake test with its printout, defects recorded and rectified before the vehicle returns to service, a competent signature, and a clean chain to the driver's daily checks. A sheet with blanks, or defects noted but never closed out, is worse than useless, because it proves the system does not work.
