Manual tachograph entries: when they're needed and how to get them right

A digital tachograph records driving time automatically, but it can't capture everything a driver does across a working day on its own — periods spent on 'other work' away from the vehicle, genuine rest taken without the card in the unit, or activity while the card itself is out of the reader for a legitimate reason. That's what manual entries exist for, and understanding when they're actually required, rather than treated as optional tidying-up, is part of the same drivers' hours discipline that keeps a record genuinely accurate.

When a manual entry is actually required

The clearest case is when a driver's card has been out of the vehicle unit — moved to another vehicle, left at base, or simply not inserted at the start of a shift — during which time driving, other work, availability or rest has taken place. On reinsertion, the driver is generally expected to manually enter what happened during that gap, categorised correctly, rather than leaving the record blank and letting the gap speak for itself. A blank period in an otherwise continuous record is exactly the kind of anomaly an examiner is trained to notice and query.

Getting the categories right

The activity categories a manual entry needs to distinguish between — driving, other work, availability and rest — aren't interchangeable, and picking the wrong one changes what the record actually shows about compliance with drivers' hours limits. A driver who genuinely spent time on other work but logs it as rest, whether through carelessness or a mistaken belief it doesn't matter which box is ticked, is creating a record that doesn't match what actually happened, which is its own problem separate from whatever the underlying hours position turns out to be.

Why sloppy manual entries create their own risk

A manual entry made carelessly — filled in from memory days later, rounded to convenient figures, or completed in a rush at the end of a long shift — can create exactly the kind of discrepancy that turns into a tachograph infringement finding even where the driver's actual hours were genuinely compliant. An examiner reviewing a record doesn't just check whether the final totals look acceptable; inconsistent or implausible manual entries are themselves a flag, because they suggest the record as a whole may not be a reliable account of what actually happened that day.

Training drivers to make entries at the time, not after the fact

The most reliable manual entries are made close to the event they're recording, while the detail is still genuinely fresh, rather than reconstructed later from a rough memory of the day. A driver who's been shown exactly how to log a card-out period correctly — which category applies, how to estimate timing reasonably when the exact minute isn't known — produces a materially more defensible record than one working it out for the first time under pressure, which is one of the more practical reasons manual entry procedure is worth its own specific mention in driver induction and refresher training.

How this changes with Smart Tachograph 2

The rollout described in our look at Smart Tachograph 2 changes some of the automatic recording capability of newer units, which over time may reduce how often a manual entry is genuinely needed for certain scenarios. That's a gradual shift tied to fleet renewal and retrofit timelines rather than an overnight change, and exactly how it affects manual entry requirements for a specific fleet's existing vehicles is worth checking against current guidance rather than assumed to have already taken effect fleet-wide.

Manual entries for non-driving activity

It's worth being clear that manual entries aren't only relevant to obvious card-out periods on the road — a driver who does genuine work-related activity before or after a driving shift, loading a vehicle before setting off or completing paperwork at the depot afterward, needs that time correctly categorised too if it wasn't captured automatically. Drivers sometimes assume that anything happening away from actual driving doesn't need recording at all, which isn't the case — other work still counts toward the overall picture of a driver's working time, even where it has no direct bearing on the specific driving-time limits themselves.

What an examiner does with a pattern of manual entries

A single manual entry, on its own, rarely draws particular scrutiny — it's a pattern that matters. A driver whose record shows an unusually high proportion of manually entered time compared to automatically recorded time, especially if that pattern clusters suspiciously close to when driving-time limits would otherwise have been exceeded, is exactly the kind of thing a Traffic Examiner is trained to look at more closely. That doesn't mean manual entries are inherently suspicious — they're a normal, expected part of an accurate record — but a fleet whose drivers rely on them unusually heavily is worth a closer look internally before DVSA takes that closer look externally.

Cross-border driving and manual entries

A driver crossing into or through other countries can encounter equipment or connectivity quirks that make a manual entry more likely than on a purely domestic route — a card reader malfunction at a border crossing, or a period where the vehicle's unit genuinely can't record correctly for a stretch of the journey. Drivers doing regular international work benefit from being specifically briefed on how to handle this, since the consequences of getting a manual entry wrong don't stay neatly within one country's enforcement regime, and a discrepancy is just as visible to a UK examiner on the driver's return as it would have been at the time.

Common mistakes with manual tachograph entries

• –Leaving a card-out period blank rather than completing the required manual entry
• –Selecting the wrong activity category, particularly confusing other work with rest
• –Reconstructing entries from memory well after the event, rather than at the time
• –Rounding timings to convenient figures instead of a genuine, if approximate, estimate
• –Assuming a manual entry is optional tidying-up rather than a required part of an accurate record
