A driver returns to the depot after a difficult shift, the work is complete, and the delivery has been made. Yet the next tachograph analysis highlights a missing manual entry, an insufficient break or an overrun caused by an unrealistic allocation. This is what causes tachograph infringements in many fleets: not one dramatic failure, but small gaps between the planned job, the driver’s actions and the records available to prove compliance.
For an operator, every infringement needs context, investigation and evidence of action. Left unmanaged, repeated issues can create avoidable risk for drivers, transport managers and the operator licence.
What causes tachograph infringements in day-to-day operations?
Tachograph infringements occur when a driver’s recorded activity does not meet applicable drivers’ hours rules, or when the required record is incomplete, inaccurate or unavailable. Some are straightforward breaches of driving, break or rest limits. Others arise because the tachograph mode was wrong, a card was not used correctly, or data was not downloaded and reviewed in time.
The detail matters. A short overrun caused by a queue at a loading bay is not managed in the same way as repeated excessive driving across a depot. Equally, an infringement report is a prompt to investigate, not proof that a driver has acted deliberately. Operators need to establish what happened, whether the record is correct, what evidence exists and how the issue will be prevented from happening again.
Driving, break and rest errors
The most visible infringements relate to drivers’ hours. These include exceeding daily, weekly or fortnightly driving limits; failing to take a qualifying break after driving; and taking insufficient daily or weekly rest. Missed compensation for reduced rest can also become an issue where it is not planned and monitored properly.
These errors are often created before the vehicle moves. A route may look achievable on mapping software but leave no margin for congestion, roadworks, a delayed loading slot, border activity or a change of collection point. If dispatchers can only see where vehicles are, rather than remaining driving time and rest requirements, a job can be allocated that is commercially attractive but operationally impossible to complete compliantly.
There are limited exceptions in the rules, but they are not a routine planning tool. A driver who has to rely on an exception regularly is usually highlighting a planning, resourcing or customer scheduling problem. The reason for any departure must be recorded appropriately, and the circumstances should stand up to scrutiny.
Incorrect activity modes and manual entries
A tachograph can only record the activity selected or inferred at the time. If a driver carries out loading, unloading, vehicle checks, paperwork or depot work while the tachograph is set to rest, the record does not reflect the working day. The same applies when drivers forget to change mode after a break or leave the vehicle on the wrong setting while waiting.
Manual entries are another frequent source of exceptions. They are needed to account for time between removing and reinserting a driver card, including other work, availability, rest, annual leave or sickness where relevant. Missing entries can make a lawful day appear incomplete. Incorrect entries can be just as problematic, particularly when they create an implausible rest period or fail to show work completed away from the vehicle.
This is not simply a training issue. Clear depot routines, sufficient time at the beginning and end of shifts, and supervisor checks all affect whether drivers can create accurate records without feeling rushed.
Card use, team driving and record availability
Using the wrong card, driving without a card when one should be used, or allowing another person to use a driver card are serious compliance concerns. Cards must be treated as personal records, not as a way to keep a vehicle moving when a driver has reached their available hours.
Team operations add another layer of risk. Both drivers need to understand when to insert cards, how to record periods in the passenger seat and how the rest rules apply to their actual shift pattern. A team vehicle does not automatically make every journey compliant.
Operators must also be able to produce records when requested. Missing driver card downloads, late vehicle unit downloads and poor record retention create their own exposure, even where the underlying driving appears compliant. For most UK operations, driver card data should be downloaded at least every 28 days and vehicle unit data at least every 90 days. A sensible operation does not wait until the deadline, because a damaged card, vehicle fault or missed connection can quickly turn a tight process into a missed download.
Planning failures behind repeat infringements
When the same infringement appears across several drivers, the root cause is rarely individual behaviour alone. It may be a fixed delivery slot that cannot be reached within legal driving time, a route plan that ignores realistic delays, or a culture where drivers feel they must finish the job regardless of their remaining hours.
Late changes are particularly difficult. A planner may divert a lorry to recover a missed collection without seeing that the driver is approaching a break or daily rest requirement. The vehicle tracking view may show a nearby asset, but proximity is not the same as availability. Compliance data needs to sit alongside live fleet visibility so decisions account for both location and legal capacity.
Subcontracting and agency cover can expose the same weakness. Drivers who are unfamiliar with local sites, paperwork processes or the company’s approach to manual entries may need more support during induction. A short, documented briefing is more useful than assuming every experienced driver follows the same routine.
Equipment faults and poor data management
Tachographs, driver cards and vehicle units can fail. A faulty printer, unreadable card, calibration issue or malfunctioning vehicle unit does not remove the operator’s responsibilities. Drivers need to know the defect reporting process and how to make the required temporary records where equipment cannot be used normally. The transport office then needs to arrange repair, retain supporting evidence and check that the issue is closed.
Calibration should not be allowed to drift past its due date. Vehicle changes, tyre size changes and repairs can also affect tachograph obligations, so workshop and compliance teams need a reliable handover process. Maintenance reminders are useful only if someone owns the action and follows it through.
Data management is equally important. Downloading files is not the same as managing compliance. Files need to be received successfully, analysed promptly, assigned to the right driver and vehicle, and retained securely. If a driver has worked for more than one operator, the business must still consider the complete picture when assessing available hours and records.
How to reduce tachograph infringements before they happen
The most effective control is a routine that joins planning, driving and review rather than treating tachograph analysis as a monthly administrative task. Before work is allocated, planners should see the driver’s remaining driving time, likely break requirement and expected finish. During the shift, exceptions should be visible early enough to change the plan. After the shift, relevant issues should be reviewed while the details are still clear.
Drivers need practical instruction, not just a policy acknowledgement. That means demonstrating manual entries, mode selection, printouts and defect procedures in the vehicles they actually use. It also means explaining why accurate records protect them as well as the business. A driver is more likely to report a mistake promptly where the response is fair, consistent and focused on facts.
A clear escalation process helps transport managers separate isolated events from operational patterns. Minor issues may call for coaching. Repeated errors may require retraining, route changes, stronger supervision or formal management action. Serious breaches require prompt investigation and a documented response. In every case, avoid altering the story to make a report look better. Good compliance relies on accurate records and credible corrective action.
Fleetalyse brings remote tachograph downloads, driver hours monitoring and live vehicle visibility into one operational view. This can reduce the gap between a planner making a decision and a compliance manager discovering its consequences weeks later. It does not replace management judgement, but it gives teams the timely information needed to use that judgement properly.
Treat each infringement as an operational signal
A tachograph report should lead to useful questions: Was the job achievable? Did the driver have the right information? Was the mode or manual entry understood? Did a vehicle issue disrupt the record? Has the same problem appeared on the same route, site or shift before?
Answering those questions consistently protects more than a compliance score. It helps build a fleet operation where drivers are not forced to choose between completing the work and completing it lawfully.
