How often must tachograph data be downloaded?

GOV.UK states that operators must periodically download data from digital and smart tachographs, the vehicle unit, every 90 days, and from driver cards every 28 days. The same sentence goes on to require that the operator analyse the information to ensure the rules have been complied with, which is the part that costs a transport office its week.

The two intervals, and the third one people forget #

28 days

Download from the driver card

GOV.UK, tachograph rules

90 days

Download from the vehicle unit

GOV.UK, tachograph rules

42 days

Used analogue charts returned by the driver to the operator

GOV.UK, tachograph rules

The third one is what catches mixed fleets. An operator running a couple of older vehicles alongside digital ones is tracking two different cycles with two different artefacts, one of which arrives as paper in a driver's bag.

None of these intervals is a single deadline. They are rolling deadlines, one per driver and one per vehicle, and they all move independently. Twenty drivers and fifteen vehicles is thirty five separate clocks, each with its own due date, each resetting when the last download happened rather than on a date the office chose.

That is what makes the job feel disproportionate to its difficulty. There is nothing hard in it. There is simply no natural moment at which it becomes due for everybody at once.

What the driver has to produce, and what the office has to hold #

Two different obligations, often conflated.

What the driver produces at the roadside

  • Charts and any legally required manual records for the current day and the previous 28 calendar days, for AETR or domestic journeys under the assimilated rules
  • Or 56 days for international journeys to and from an EU member country
  • The driver card, where one has been issued

GOV.UK, tachograph rules

What the operator holds

  • Regular checks of charts, manual records and digital data to ensure compliance
  • The ability to produce records to enforcement officers for 12 months
  • All reasonable steps to prevent breaches of the rules

GOV.UK, responsibilities of vehicle operators

The retention periods and the limits that sit behind them are set out on drivers' hours record keeping.

The exceptions that generate the most paperwork #

A lost or broken card is where the admin multiplies. GOV.UK states that where it is impossible to use a driver card, because it has been lost, stolen or damaged or is malfunctioning, a driver may drive without it for a maximum of 15 calendar days, or longer if necessary for the vehicle to be returned to its premises.

That is allowed provided they produce two printouts, one at the start of the day and another at the end. The driver must report the issue to DVLA and request a replacement card within seven days.

Read that as an administrative process rather than a rule and you get three nested clocks on one driver.

  • Seven days to request the replacement

  • Fifteen days of permitted driving

  • A daily pair of printouts

    That have to be collected, identified and filed.

Multiply by the number of cards that go missing in a year and the exception is not an exception at all. It is a recurring workflow that nobody designed.

The equipment deadlines are dated and public #

DVSA's approved tachograph centre special notice 01-23, published 11 January 2024, sets out when a full or transitional smart tachograph 2 must be fitted:

FromApplies to
21 August 2023Newly registered in scope vehicles undertaking international journeys
21 February 2024All newly registered in scope vehicles, regardless of journey type
31 December 2024Retrofit into in scope vehicles with an analogue or digital tachograph on international journeys
19 August 2025Retrofit into in scope vehicles fitted with a smart tachograph 1 on international journeys
1 July 2026Newly registered goods vehicles over 2.5 tonnes on international journeys for hire and reward

Which parts of the download cycle run on rules #

Runs on rules

  • Knowing which driver cards are due or overdue for download today, which is date arithmetic against a 28 day interval
  • Knowing which vehicle units are due against the 90 day interval, the same arithmetic on a different clock
  • Spotting a driver with no data at all for a period, which is a gap in a set
  • Tracking the seven day and fifteen day clocks on a broken card, which is three dates and a count
  • Knowing which vehicles are inside which equipment deadline, which is published dates against a fleet list

Needs a transport manager

  • Deciding what an infringement means for that driver, which is a management responsibility
  • Deciding whether a pattern is a training issue or a planning issue, which is the substance of the duty

Operators in DVSA's earned recognition scheme already live with a version of this rhythm: all key performance indicators are measured over four week periods, reported at the end of the period and sent to DVSA four weeks later. Whether or not a business is in the scheme, the shape of the problem is the same. The detection is arithmetic, the response is management, and the two keep getting done by the same person in the same hour.

The wider set of licence undertakings that this sits inside is covered on operator licence paperwork, and to put hours against your own compliance cycle, start with the cost of admin time calculator or sort the tasks with the which tasks run on rules checklist.

Questions people ask

How often must tachograph data be downloaded?
GOV.UK states that operators must periodically download data from digital and smart tachographs, known as the vehicle unit, every 90 days, and from driver cards every 28 days, and analyse the information to ensure that the rules have been complied with.
Is downloading the data enough on its own?
No. The same GOV.UK guidance pairs the download with analysis, and the operator responsibilities page requires regular checks of charts, manual records and digital data, the ability to produce records to enforcement officers for 12 months, and all reasonable steps to prevent breaches of the rules. A download that nobody reads satisfies none of that.
What happens if a driver card is lost or stops working?
GOV.UK states that where it is impossible to use a driver card, because it has been lost, stolen or damaged or is malfunctioning, a driver may drive without the card for a maximum of 15 calendar days, or longer if necessary for the vehicle to be returned to its premises, provided they produce two printouts, one at the start of the day and another at the end. The driver must report it to DVLA and request a replacement within seven days.
Which vehicles need a smart tachograph version 2?
DVSA special notice 01-23, published 11 January 2024, sets the dates. From 21 February 2024 a full or transitional smart tachograph 2 must be fitted to all newly registered in scope vehicles regardless of journey type. Retrofit deadlines applied from 31 December 2024 for analogue and digital units and from 19 August 2025 for smart tachograph 1 units on international journeys. From 1 July 2026 the requirement extends to newly registered goods vehicles over 2.5 tonnes on international journeys for hire and reward.
Does download software make an operator compliant?
No. Tachograph record keeping and the duty to check the data are legal duties of the operator, the transport manager and the driver. Software can tell you sooner that a card is overdue or that a pattern looks wrong. The duty to check, to act and to prevent breaches does not move.
