Tachograph infringements and driver debriefs
Analysing tachograph data is only half the job; the Traffic Commissioner wants to see you act on it. Categorise each infringement by severity, debrief the driver in a documented conversation, and have them sign to confirm - the signature is the evidence, and repeat offenders need escalation.
Downloading and analysing tachograph data is expected; acting on it is what a Traffic Commissioner actually wants to see. An operator who can show a pile of analysis but no evidence that drivers were debriefed and infringements addressed is often in a worse position than one who found fewer problems but dealt with every one.
Analyse, then categorise
Once driver-card and vehicle-unit files are downloaded on time and analysed, each infringement should be categorised by severity - from minor overruns to serious breaches of driving, break or rest limits, and the most serious matters such as apparent falsification or driving without a card. Severity drives the response.
The debrief
A debrief is a documented conversation with the driver about the infringements found:
- Show the driver what happened and when.
- Establish why - a genuine operational cause, a misunderstanding, or a deliberate breach.
- Agree what changes, and make clear the standard expected.
- Record it, and have the driver sign to confirm they have seen and understood.
That signature is the evidence. It turns "we told them" into something you can put in front of an examiner.
Repeat offenders
A pattern matters more than a single event. A driver who keeps breaching after a debrief needs escalation - retraining, a formal warning, and a clear record of each step. Traffic Commissioners look for a system that catches repeat offenders and does something about them, not one that debriefs the same infringement every month.
Why paper falls down
Manual analysis and paper debriefs drift: files get downloaded late, analysis backs up, debriefs slip, and signatures are missing when DVSA asks. The gap between "the data existed" and "we acted on it and can prove it" is where operators lose credibility.
How OperatorCompliance helps
OperatorCompliance analyses each driver's card and vehicle-unit files, produces an infringement report categorised by severity, and sends it to the driver to read and e-sign in their own language - with the transport manager countersigning. The signed report is stored with an audit trail, and unsigned reports are chased automatically, so the debrief loop closes itself. See how it works or start a free 14-day trial.

Frequently asked questions
What is a tachograph driver debrief?
A debrief is a documented conversation with the driver about the infringements found in their tachograph data. You show the driver what happened and when, establish why, agree what changes and make clear the standard expected, then record it and have the driver sign to confirm they have seen and understood. That signature is the evidence that you acted.
How are tachograph infringements categorised?
Each infringement is categorised by severity, from minor overruns to serious breaches of driving, break or rest limits, and the most serious matters such as apparent falsification or driving without a card. Severity drives the response, so a minor overrun and an apparent falsification are handled very differently, and the most serious matters need the firmest action.
What should I do about repeat offenders?
A pattern matters more than a single event. A driver who keeps breaching after a debrief needs escalation: retraining, a formal warning, and a clear record of each step. Traffic Commissioners look for a system that catches repeat offenders and does something about them, not one that debriefs the same infringement month after month with no change.
Why is analysing tachograph data not enough on its own?
Because the Traffic Commissioner wants to see you act on it. An operator who can show a pile of analysis but no evidence that drivers were debriefed and infringements addressed is often in a worse position than one who found fewer problems but dealt with every one. The gap between the data existing and proving you acted is where credibility is lost.
