Transport Compliance Audits
Transport Compliance Audits support for operators that need an independent review of licence undertakings, maintenance evidence, tachograph controls, driver records and DVSA readiness against the standards a Traffic Commissioner expects to see.

What an operator compliance audit covers
An operator compliance audit puts the same questions to your evidence file that DVSA would ask in a desk-based assessment, and that the Traffic Commissioner would expect answered in an inquiry bundle. The point is not to repeat the licence undertakings back to you. It is to test whether you can actually evidence them on the day.
The scope normally takes in PMI records and intervals, brake test results, defect raising and close-out, tachograph vehicle and driver downloads, missing mileage, infringement analysis and debrief notes, driving licence checks, Driver CPC records, the Transport Manager’s hours and exercise of continuous and effective control, and the accuracy of the VOL record against the live operation.
Operators usually commission an audit for one of three reasons: a proactive check while nothing is going wrong, preparation for a Traffic Commissioner hearing or DVSA visit, or recovery after a prohibition, a fall in OCRS or a failed internal review. Each starting point shapes how deep the sampling needs to go.
Audit scope for DVSA-style evidence
A useful audit works to a defined sample rather than a broad sweep. As a working baseline, expect at least three to six months of records per vehicle and per driver, with the proportion increasing on a larger fleet or where OCRS sits in the amber or red band. Random sampling tends to surface the issues that a tidy presentation file is designed to hide.
The maintenance review reads the PMI sheet against the inspection interval on the licence, checks the brake test method and result against the operator’s policy, and follows defects from driver report through repair sign-off to closure. The tachograph review checks 28-day vehicle unit downloads and 28-day driver card downloads, looks for missing mileage, reviews infringement reports and tests whether debriefs were signed, dated and actioned where a pattern was forming.
The licence record review compares the VOL entry (legal entity, operating centre, vehicle and trailer authority, Transport Manager nomination and hours) with what is happening on the ground. Most operators who have not audited for a year find at least one mismatch here, and a mismatch on VOL is one of the first things a Traffic Commissioner asks about.
When to commission a compliance audit and what happens after
Use an audit when no independent review has taken place for 12 months, when a DVSA visit or letter has exposed concerns, when OCRS has slipped, or when correspondence has arrived from the Office of the Traffic Commissioner.
Where a hearing is in prospect, commission the audit as early as the timetable allows. Findings need weeks, not days, to be acted on, evidenced and reflected in fresh records. An audit completed the week before a public inquiry, with the action log empty, will read as a paper exercise and the Traffic Commissioner will treat it that way.
After the work, the operator should receive a written report that sets out each finding, a risk rating, the regulatory exposure, the recommended corrective action, the named owner, a due date and the evidence required to close. The completed action log then becomes the second exhibit, proof that the issues were identified and resolved.
Linked audit records and next steps
Compliance audit evidence areas
Vehicle maintenance
Review PMI records, brake tests and defect close-out. Check whether intervals match vehicle age, mileage and operating risk.
Tachograph controls
Check download schedules, analysis reports and debrief records. Identify late downloads and unmanaged infringement patterns.
Driver Records
Driving licence checks, Driver CPC records, check frequency. Confirms drivers are legally entitled to drive the vehicles they are operating.
Licence Record Accuracy
Comparison of the VOL record against the current operation: entity name, operating centres, vehicle authority, trailer authority and TM nomination.
Transport Manager evidence
Review site visit records, maintenance meeting notes and working examples showing genuine operational involvement.
Written Report and Action Log
Findings, severity rating and recommended actions. Action log tracks completion. Together they form an evidence file for TC or DVSA use.
Useful Background Before Audit
The latest register information is only background. The real audit position depends on the operator’s own files, records, systems and the evidence trail behind each entry. Two operators with identical VOL records can sit on very different OCRS scores once the maintenance and tachograph evidence is opened up.

Commission a transport compliance audit
Our compliance audit covers the full scope of a DVSA desk-based assessment and produces a written report with a tracked action log. The report and the closed-out log together form the evidence file you can hand to DVSA, an insurer or the Traffic Commissioner without rewriting anything. Operator Licence Ltd can help review this evidence, identify the gaps and connect you with the right specialist support for audit follow-up.
What to prepare before a compliance audit
A compliance audit produces better findings when records are organised before the auditor opens them. Have at least six months of PMI sheets, brake tests and defect close-out documents per vehicle, filed in date order so gaps are visible at a glance.
Have tachograph downloads, the download log itself, analysis reports, infringement letters and signed debrief records ready, with a note of when each driver was last spoken to about repeat issues. Driver files should hold the most recent licence check, Driver CPC hours to date and any periodic training relevant to the work, such as ADR, Moffett, tanker or skip work.
Keep a printed or saved view of the current VOL record covering the legal entity, operating centres, vehicle and trailer authority and Transport Manager nomination. The first job of the audit is to test whether that record still matches the live operation. Where it does not, the licence is the document that needs to change, not the operation that needs to be hidden.
Expert insight: In practice, the records that fail an audit are rarely missing. They are inconsistent. A PMI sheet that shows a brake imbalance, no defect raised, and the vehicle back in service the same day will do more damage at inquiry than a missing sheet, because it shows the system was followed and the issue was waved through.

Transport Compliance Audits FAQs
What does a transport compliance audit check?
It tests licence records, maintenance evidence, defect systems, tachograph downloads and analysis, driver files, Transport Manager involvement and the operator’s readiness for a DVSA desk-based assessment.
When should an operator commission an audit?
Before DVSA contact, after a prohibition, when OCRS worsens, before a Traffic Commissioner hearing, or where no independent review has happened for 12 months. Acquisitions and Transport Manager changes are also sensible trigger points.
Does an audit help at public inquiry?
It can be one of the stronger exhibits, but only where the report is followed by a closed-out action log with dated evidence. A report with findings and no resolution is treated as paperwork rather than change.
What records should be ready before the audit?
PMI sheets, brake tests, defect records, tachograph downloads, analysis reports, debrief notes, driver licence checks, Driver CPC evidence and a current view of the VOL record.
Where should official guidance be checked?
Check current DVSA roadworthiness guidance and the Senior Traffic Commissioner’s Statutory Documents alongside the undertakings on your own licence.
