Tachograph analysis is the process of reviewing the data downloaded from driver cards and vehicle units to identify drivers’ hours infringements, working time concerns, missing periods and patterns that might indicate a wider management problem. Analysis software generates the reports. What operators do with those reports is where compliance either stands or falls.
DVSA examiners and Traffic Commissioners are not primarily interested in whether infringements happened. They are interested in whether the operator knew about them and what management did in response. An operator with modest infringement numbers who can produce debrief records, documented corrective actions and evidence of management review is in a far stronger position than one with a clean-looking report that nobody can explain.
What good tachograph analysis management looks like
Reports should be reviewed regularly, at a frequency that matches the fleet size and risk profile. Infringements should be categorised, investigated and followed up with drivers. Debrief records should be kept, not just sent out by email and filed. Where the same driver is generating the same types of breach repeatedly, that pattern should be escalating to the Transport Manager and triggering a management response.
Missing mileage, unknown driver periods and manual entry records also need attention. They can indicate incomplete downloads, equipment problems or drivers operating without valid cards. Each of those carries its own compliance risk. None of them resolve themselves without active management.
Official guidance on drivers’ hours rules is on GOV.UK: Drivers’ hours.
Analysis is only one part of the picture
Tachograph analysis sits within a broader framework of operator licence compliance. Download frequencies, working time calculations, agency driver management, financial standing and the Transport Manager’s overall role in overseeing the operation all connect to the same central question: is this operator in effective management control of their fleet?
For some operators, a tachograph review is prompted by a specific concern, an upcoming licence renewal, a customer audit, deteriorating infringement rates. For others it forms part of a wider transport compliance audit following a period of business growth or a management change. Either way, the starting point is understanding what the current records actually show.
A practical review can cover
- Whether driver card and vehicle unit downloads are being completed on schedule.
- Infringement trends, recurring patterns and what management responses are documented.
- Driver debrief procedures and evidence that follow-up action has been taken.
- Missing mileage, unknown periods and manual entry controls.
- Agency driver records and whether they are being collected consistently.
- Working time compliance alongside drivers’ hours obligations.
- Whether the nominated Transport Manager is actively engaged with the analysis process.
- Responsibilities between directors, the Transport Manager, drivers and administrative staff.
When to request support
Tachograph analysis support is commonly requested when infringement levels are rising, when management reports are not being reviewed regularly, when a business changes fleet management software, or when a customer, DVSA examiner or auditor has started asking questions about records.
It is also useful when a new Transport Manager joins and needs to understand what the existing data shows. Early intervention is considerably simpler than attempting to reconstruct records and explanations after concerns have already been identified by an enforcement authority.
Making an enquiry
Useful information to have ready includes licence type, fleet size, number of drivers, your tachograph analysis provider or software, recent infringement reports and any upcoming compliance deadlines or regulatory contact. If you are unsure whether an issue is straightforward or potentially more serious, an independent review of the records is usually the right first step.
