PG9 Prohibition Support

A PG9 prohibition is not just a vehicle problem. It is a signal that something in the maintenance system failed to catch a defect before that vehicle went onto the road. How an operator responds to it, and how much they can demonstrate about what went wrong and what has changed, will shape how seriously DVSA and the Office of the Traffic Commissioner view the incident.

A single prohibition that forms part of an otherwise strong compliance record looks different from a prohibition that sits on top of weak PMI records, missing brake test evidence and thin management oversight. Context matters enormously.

What happens after a PG9 is issued

The immediate concern is getting the vehicle back into service legally. Beyond that, operators holding any licence type, whether restricted, standard national, standard international or PSV, need to consider whether the same weakness that produced this prohibition might exist elsewhere in the fleet.

DVSA uses prohibitions as a trigger for broader scrutiny. A PG9 on one vehicle can lead to examination of the entire maintenance system. Questions about PMI intervals, brake testing arrangements, defect reporting quality, vehicle inspection records and the role of the nominated Transport Manager in overseeing the process are all in scope. Further information about operator responsibilities can be found on GOV.UK: Guide to Maintaining Roadworthiness.

The records that will be reviewed

A practical review following a PG9 will typically examine the prohibition notice and the specific defects recorded, the recent PMI inspection history for that vehicle, repair documentation, defect reporting records, brake testing evidence, MOT history and whether similar defects have appeared on other vehicles in the fleet. Where the maintenance is handled by a third-party provider, the question is what checks the operator was carrying out on the provider’s work.

Driver walkaround check records are also commonly reviewed. If a defect that a driver should have spotted is also showing in the PMI records as a recurring issue, that creates a more difficult picture to explain.

What a review can cover

• The PG9 notice itself and what the specific findings indicate about maintenance management.
• PMI records, inspection history and repair documentation for the affected vehicle and the wider fleet.
• Defect reporting systems and whether reported defects are being acted upon and closed correctly.
• Brake testing arrangements and supporting evidence.
• Driver walkaround check procedures and whether they are genuinely operating.
• Transport Manager oversight and evidence of active management control.
• Whether wider fleet compliance concerns exist that could attract further regulatory attention.
• Preparation for a compliance audit, DVSA investigation or Traffic Commissioner hearing.

Act early

The most useful time to review maintenance systems after a prohibition is before DVSA follows up. If the records are in good shape, that review provides reassurance. If they are not, it gives the operator time to address problems before a formal audit or investigation surfaces them.

Where a matter is already progressing towards a regulatory hearing, any operational review should be coordinated with legal advisers to ensure consistency between what the records show, what has been communicated formally and what corrective actions are being presented as evidence of improvement.

Making an enquiry

Gather the PG9 notice, recent PMI sheets, maintenance records, repair invoices, defect reports, brake testing printouts and any DVSA correspondence before making contact. Having the licence type, fleet size, operating centre details, maintenance provider arrangement and Transport Manager position clear will help determine what kind of review is most appropriate and how quickly it needs to happen.
