15 Month Rule: Defect Reporting for UK Transport Managers

15 Month Rule: Defect Reporting for UK Transport Managers

Every driver must report a defect the moment they find one, in writing or electronically, and every operator must have a system that assesses, rectifies and records that report. Reports listing faults must be kept for at least 15 months, nil reports are worth keeping too, and photos or digital records count as valid evidence. Get the paper trail wrong and DVSA will find out at the roadside, not in an audit.

TL;DR:

• Accurate defect records must be kept for at least 15 months, with photos and digital evidence accepted as valid documentation.
• A single designated person must triage defect reports immediately, prioritizing dangerous faults for immediate removal from service.
• Drivers must perform daily walkaround checks at least once within 24 hours and report specific details including severity, repair, and sign-off.
• Digital systems should include secure time stamps, signatures, photo attachments, and an exportable audit pack to ensure roadside readiness.
• Missing or vague defect reports can lead to warnings, systemic failure assessments, and difficulty challenging vehicle prohibitions at inspections.

Legal obligations and enforcement risks under the defect reporting process

Drivers carry the duty to spot and report; operators carry the duty to build a system that actually catches what drivers report. That split matters because examiners judge the operator’s side of it, not the individual driver’s memory. A functioning defect reporting process needs a route for the report to travel, someone to receive it, and a record that shows what happened next.

DVSA examiners lean on this heavily during a maintenance investigation visit. Clear evidence that walkaround checks were skipped, or that a vehicle ran with a known defect, is one of the fastest routes to a referral to the Traffic Commissioner.

Weak defect records also feed into the Operator Compliance Risk Score, colouring every future roadside encounter your vehicles have.

Why this bites harder than most operators expect:

• A missing or vague defect report during an MIVR can trigger a formal warning even when no vehicle was actually unsafe on the day.
• Repeated gaps in reporting are treated as a systemic maintenance failure, not a one off paperwork slip.
• Poor records make it harder to challenge a prohibition, because examiners rely on contemporaneous notes and signed logs to justify their decision.

One statistic worth sitting with: defect reports must be retained for a minimum of 15 months. Miss that window and you have no defence when an inspector asks to see your history.

Daily walkaround checks: what drivers must inspect and record

A walkaround check has to happen at least once in every 24 hour period a vehicle is used, and it can be delegated to whoever drives that day, provided they know what to look for. DVSA expects drivers to carry out the check before the journey starts, then report anything found, including faults that appear mid journey.

The core inspection points are:

1. Tyres and wheels, checking tread, damage, pressure and wheel nut security.
2. Lights and indicators, front, rear, brake and hazard.
3. Brakes, including warning lights and any unusual pedal feel.
4. Steering and mirrors, checking play, damage and visibility.
5. Emergency exits and equipment on passenger vehicles.
6. Load security and any warning indicators on the dashboard.

Whatever a driver finds, the report needs specific fields to be useful later: vehicle registration, date, a description of the defect, the reporter’s name, who they reported it to, an assessment of severity, what rectification was carried out, who repaired it and the date it was completed. DVSA’s own HGV walkaround template covers exactly this, and using it (or an equivalent digital form) keeps every driver reporting the same way.

Pro Tip: Treat a rattle or a slow leak as seriously as a warning light. Minor symptoms are often the first sign of a fault that becomes safety critical within days.

From report to rectification: a practical operator workflow

Every fleet needs one named person who receives every defect report and has the authority to pull a vehicle out of service. Without that owner, reports drift into inboxes nobody checks, and a dangerous defect sits unresolved because three people assumed someone else was dealing with it.

Once a report lands, triage it by severity straight away:

• Dangerous defects mean the vehicle stops running immediately, no exceptions.
• Significant defects get prioritised for repair, usually before the vehicle’s next scheduled use.
• Advisory items get scheduled into the next planned maintenance visit rather than fixed on the spot.

From there, the workflow needs a paper trail that would survive scrutiny: who assessed the defect, which repairer fixed it, what parts went in, and a signed, dated confirmation before the vehicle goes back on the road. That operator side of the process is what separates a fleet that can prove due diligence from one that just hopes nothing goes wrong. Skipping the sign off step is the single most common gap examiners find, because it’s the step that feels least urgent when a vehicle is needed back on the yard.

Record retention, audit readiness and what inspectors will ask for

Keep every defect report that lists a fault for a minimum of 15 months. Nil reports, where a driver confirms nothing was found, don’t need the same length of retention, but keeping them for at least three months gives you evidence that checks were actually happening on days without a fault.

What inspectors actually want to see, beyond the report itself:

• Time stamps that show when the check happened and when the report was filed.
• A signature or digital equivalent identifying who assessed the defect.
• Photos or video where a defect was significant enough to warrant them.
• Repair invoices or job cards linked back to the original report.

This isn’t paperwork for its own sake. A prohibition endorsed ‘S’ signals a significant maintenance failure to the Traffic Commissioner, and the operators who avoid that endorsement tend to be the ones who can produce a clean, linked record within minutes of being asked, not days.

Digital defect reporting: what a good system needs to do

Paper forms still pass muster with DVSA, but they’re slow to search and easy to lose. Electronic records are explicitly accepted provided they carry the essential fields, a time stamp, and are readily accessible when an examiner asks for them.

A digital system built for this job should give you:

• Secure date and time stamping on every report, not just the date it was typed up.
• Digital signatures from both the driver reporting and the manager assessing.
• Photo or video attachments stored against the specific defect record.
• Searchable records you can pull by vehicle, date range or defect type in seconds.
• An exportable audit pack ready to hand to a DVSA examiner without assembling it on the spot.

Configure the workflow so a vehicle physically cannot be marked as returned to service until someone has signed off the assessment. That single rule closes the most common gap in operator records.

A digital driver app supporting multilingual reporting for mixed nationality fleets, automated alerts when a defect sits open too long, and audit-ready packs built around the same fields DVSA guidance sets out can help manage defect reporting effectively.

Pro Tip: If your drivers speak several languages, a defect report written in the wrong terminology is as good as no report at all. Multilingual forms cut that risk out entirely.

Where defect reporting usually breaks down

Most defect systems don’t fail because drivers stop reporting. They fail because someone stops reading the reports, or because there’s no single named person accountable for closing them out. I’ve seen fleets with excellent walkaround compliance and a completely useless paper trail, because reports sat in a drawer with no assessment attached.

Three fixes solve most of it: one defects inbox that everything routes through, a single composite walkaround form with a nil box that drivers can’t skip, and a mandatory sign off before any vehicle returns to service. None of that is complicated. It just needs someone to insist on it every single day, not just before an audit.

Make your defect trail audit ready with compliance software

Compliance software for operators can map directly onto the fields DVSA expects: digital signatures, automatic time stamping, photo evidence attached to each report, and an audit pack you can export in one go rather than assembling from multiple folders.

For transport managers running mixed nationality fleets, the driver app works in English, Polish, Romanian, Lithuanian and Bulgarian, so a defect gets reported in the language a driver actually understands. Automated alerts flag any report sitting open too long, which means fewer defects still live at roadside checks and a faster route to closure when something does need fixing. Reviewing an MIVR becomes a matter of exporting a pack rather than scrambling through paper.

Plans start at £9 a month on the Starter tier, scaling up through Standard and Professional as your fleet grows. See how it fits your operation on the pricing page, or look at what’s built specifically for transport managers running day to day compliance.

FAQ

What is the procedure for reporting a vehicle defect?

A driver reports any defect found during a walkaround check or journey in writing or electronically, giving the vehicle registration, defect details and severity. The operator then assesses it, arranges rectification and records the repair details before the vehicle returns to service.

How long do I need to keep vehicle defect reports?

Reports listing an actual fault must be kept for at least 15 months. Nil reports, confirming no fault was found, are recommended to be kept for at least three months as evidence that checks were carried out.

How do I report an unsafe vehicle to DVSA?

DVSA provides an online form for reporting a serious safety defect or vehicle recall. Serious safety concerns found during operator checks should also be logged internally and can lead to an immediate or delayed prohibition if DVSA examiners find them at the roadside.

What counts as a dangerous defect versus an advisory one?

A dangerous defect means the vehicle must stop running immediately, while an advisory defect can be scheduled into the next maintenance visit. The distinction comes from DVSA’s categorisation of vehicle defects, which examiners use to decide whether a prohibition is warranted.

Can digital defect reports replace paper walkaround forms?

Yes, provided the electronic record includes the essential fields, a time stamp and is readily accessible when DVSA asks to see it. Tools such as Operatorcompliance build this in as standard, with signatures and photo evidence attached to every report.
