Smart tachograph 2 is the current generation of tachograph, adding better positioning, border-crossing records and anti-fraud measures. The changeover has been phased, and the main retrofit deadlines for older international HGVs have passed. Further provisions affect light goods vehicles and new registrations, so the vehicle-specific date matters.
For a previously in-scope HGV undertaking international journeys, analogue, digital and smart 1 retrofits should now have been completed. UK-only fleets with working older units may not need to retrofit, but a faulty smart 1 unit must be replaced with smart 2. Qualifying light goods vehicles over 2.5 tonnes used for international hire or reward were brought into a smart 2 requirement from 1 July 2026; check exemptions and the full-unit requirement.
Smart tachograph 2 records extra data, including border crossings. Make sure your download and analysis tools read the new files properly, and that drivers know the rules for recording ferry and train legs.
A retrofit deadline applies to a vehicle already registered and fitted with an older unit. A new-registration rule applies when a vehicle first enters service. Those are different questions. A UK-only HGV with a working analogue or older digital tachograph is not automatically subject to the international retrofit deadlines simply because it has a tachograph. But a newly registered in-scope vehicle faces its own smart-2 fitment requirements even on domestic journeys.
DVSA’s updated goods-vehicle guidance says all newly registered in-scope vehicles have needed smart 2 from 21 February 2024, regardless of journey type. It also says that from 24 December 2025 all newly registered goods vehicles requiring such equipment must have a full smart 2 unit, while transitional smart 2 units fitted to earlier registrations do not need replacing solely for that reason. Do not read the older workshop notice in isolation; the later DVSA guide is the place to check the current new-registration position.
For an existing UK-only fleet, an analogue or older digital unit may continue to be used if it works and is lawful for that vehicle. When a smart 1 unit becomes faulty, though, the DfT workshop notice says it must be replaced with smart 2 regardless of whether the truck crosses a border; that rule has applied since 21 February 2024. A workshop deciding what can be fitted needs the old unit type, vehicle’s registration status and journey pattern. “Replace like for like” is not a safe blanket instruction.
For international HGVs, the older retrofit deadlines were 31 December 2024 for analogue or non-smart digital units and 19 August 2025 for smart 1. The 2023 newly registered international-vehicle requirement was an earlier stage, with transitional smart 2 equipment accepted because the full location-authentication facility was not available on the original start date. Ask an approved centre to confirm the installed unit type and fitment obligations on each registration.
International hire-or-reward work in a goods vehicle over 2.5 tonnes brought more light vehicles into tachograph rules from 1 July 2026. The live DVSA tachograph guidance says a full smart 2 must be fitted for relevant journeys, subject to a stated own-account exclusion where driving is not the driver’s main activity and other exemptions. That is a material change for an operator whose vans previously did not need the equipment. Check the vehicle or combination’s maximum weight and the nature of the international job before sending it abroad.
An operator that occasionally takes continental work cannot defer the equipment decision until the driver reaches the port. If the journey is in scope, the vehicle and driver need compliant equipment and records for that trip. Include the unit fitment check in the work-acceptance process alongside the licence, community licence and driver documentation checks.
A smart 2 tachograph adds automatic border-crossing and positioning information, among other functions. It can help enforcement authorities target checks, but it does not remove the driver’s responsibility to record activities correctly or the operator’s download and analysis duty. In particular, manual entries for work away from the vehicle still matter, and the driver must use the correct ferry mode where the ferry-rest derogation is used.
Older download and analysis software may need updating to read the extra smart-2 fields. Test it against a real vehicle file before the first international dispatch, then look for gaps in unknown-driver time, border events and activity modes. Even a legally fitted unit does little for compliance if nobody can analyse what it produced.
For each registration, record the gross or maximum laden weight, typical journeys, whether it carries goods for hire or reward, first-registration date, fitted tachograph generation and last calibration/inspection. Add the next planned international journey. This small matrix exposes the cases that need a retrofit or legal check without treating a whole mixed fleet as identical.
When a unit fails, tell the approved tachograph centre the entire context: the existing generation, journey types and registration date. Keep the replacement certificate and evidence of installation with the vehicle file. If a driver has to run without functioning equipment because of an unexpected breakdown, follow DVSA’s limited repair and manual-record procedure, and do not assume that an international authority will accept the same workaround as a domestic one.
The deadlines above were checked against DVSA’s current tachograph chapter and the DfT replacement notice in September 2026. The older 2023 notice explains the transitional phase, but where it speaks about future fitment it should be read alongside the later guidance. This article is an overview, not a unit-specific approval; confirm a borderline vehicle with an approved centre and the live official text.
