When UK-EU haulage needs 56 days of tachograph records, why AETR and domestic work stay at 28, and how to plan international jobs without gaps.
QUICK ANSWER
On an international goods run, two things decide your tachograph obligations: which rulebook the journey falls under, and how many days of records the driver must carry. Journeys between the UK and the EU run under the assimilated drivers' hours and tachograph rules, and the driver must be able to produce the current day plus the previous 56 days of records. A journey that goes to, from or through a non-EU country in the AETR group - Switzerland, Norway, Turkey, the Balkans - runs under AETR for the whole trip, and the carrying period stays at the current day plus the previous 28 days. Purely domestic UK work stays at 28 days too. So “international” does not automatically mean 56 days: it is UK-EU work specifically that carries the longer trail.
Don't over-simplify. “Non-UK” does not mean 56 days, and “post-Brexit Europe” does not mean AETR. A standard UK-EU load is assimilated and 56 days; only a route that touches a non-EU AETR country is AETR and 28 days.
The 56-day trail reaches backwards. It includes the domestic days the driver worked before crossing - trunking, yard work, training, leave - not just the days abroad.
Two rule sets govern international goods movements for a GB-registered HGV, and which one applies turns on the geography of the journey - not on what you are carrying or who you are carrying it for. Settle the rule set first, because the driving limits, the rest rules and the number of days of records all follow from it.
The “assimilated rules” are Regulation (EC) 561/2006 and Regulation (EU) 165/2014 as they have effect in the UK - the rules most operators still call the “EU rules”. The label changed to “assimilated” from 1 January 2024, but the substance is the system you already run under at home.
They apply to journeys wholly within the UK and to in-scope goods journeys between the UK and the EU, for UK or EU-registered vehicles. So a curtainsider from the Midlands to Germany, a fridge trailer from Kent to France, or a groupage load via Holyhead to the Republic of Ireland is UK-EU goods work - assimilated rules, 56-day records.
AETR is the European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport. If any part of the journey goes to, from or through a country that is in the AETR group but is not an EU member, AETR rules apply to the whole journey - including the EU motorways you run on and the leg inside the UK.
In practice that catches journeys involving Switzerland or Norway, and anything reaching into the Balkans, Turkey, Moldova and further east. A run through Switzerland to northern Italy is an AETR journey end to end, even though most of the mileage is on EU roads.
The key point for records: AETR has not adopted the EU's 56-day change, so an AETR journey carries the current day plus the previous 28 days, not 56. Do not treat “AETR” as shorthand for “anything outside the UK” - that is where the mistakes start.
For day-to-day driving you will not notice a difference. The core limits are the same under both - nine hours' driving (extendable to ten twice a week), a 45-minute break by 4.5 hours, and the daily and weekly rest rules. The divergences are few but real:
This is where international UK-EU work diverges sharply from domestic and AETR work, and where operators most often get caught out.
The roadside carrying period for in-scope UK-EU goods work doubled from 28 days to 56 days. In EU law the change applied from 31 December 2024. In GB law it was brought in by the Drivers' Hours and Tachographs (Amendment and Modification) Regulations 2025, in force from 21 April 2025, which inserted a new paragraph into Article 36 of the assimilated tachograph regulation for vehicles within the UK-EU goods scope.
There is a practical wrinkle in that gap. Between 31 December 2024 and 21 April 2025, a GB truck checked on the continent already faced the 56-day expectation, because that was what EU enforcers were applying. If you run internationally, treat 56 days as the working figure from the EU date, not the GB one.
The change is targeted. It applies to vehicles on in-scope international transport between the UK and the EU - not to domestic work, and not to AETR journeys. GOV.UK's goods-vehicle tachograph guidance states it plainly: keep 56 days for UK-EU international journeys, and 28 days for AETR international journeys and for domestic work under the assimilated rules.
So an operator running a mix can be tracking two carrying periods at once: 28 days for domestic and AETR work, 56 days for UK-EU work. A driver who did a fortnight of UK trunking and is now loading for Calais needs the longer record with them.
A common and expensive mistake is to check only the international days. The roadside look-back is backward-looking: when a driver starts an in-scope UK-EU job, the 56-day window reaches into the days before the crossing.
Take a driver who did two weeks of pallet-network trunking, three days in the warehouse, a day off, then a France run. The France run brings the driver into the 56-day requirement, so all of that earlier domestic work, other work and leave must be properly recorded if it falls inside the window. The international driving day is rarely the problem; the days before it are.
The carrying window is an activity record, not just a driving-time window. The driver must be able to produce a complete, explainable trail for the whole period, covering:
The carried period has to be continuous. Every day in it must be accounted for, including days the driver did not drive an in-scope vehicle. A gap with no explanation reads, to an enforcer, like a record that has gone missing. A day off the vehicle can be covered by a manual entry on the digital tachograph, a manual record on printout paper or the back of an analogue chart, or the EU “Form of attestation of activities” signed by operator and driver.
An important international caveat. The UK lets occasional drivers cover a whole gap week with a single “block” entry, and accepts attestation forms. That concession is for UK journeys. Foreign enforcers may not accept block entries or attestations in the same way, so for international work keep full, separate daily records for every day of the carried period.
Agency and occasional drivers need particular care. A driver who normally works for someone else, or normally works in the warehouse and only drives occasionally, can arrive with a record gap that becomes your problem the moment you put them on a European load.
Possibly not. Older driver cards - first-generation and smart version 1 - were designed around the old 28-day requirement and can start overwriting the oldest entries once 56 days are demanded, particularly the start and end country entries. The card alone may not show the full period.
Where the card cannot store the full 56 days, you have two practical fixes:
Smart tachograph version 2 cards are built to hold and show the full 56 days from the card itself. Until your fleet is fully on version 2, do not assume the card will be enough on an international run - back it with printouts or downloaded data, and keep enough approved print roll in the cab.
At the start and end of each daily working period the driver must record the country - and, where required, the place. Pre Smart Tacho 2 fitment on a multi-border run older equipment needed the country symbol entered manually at each crossing, which was easy to forget in a port or tunnel queue.
The Smart Tachograph version 2 records border crossings automatically. Where the vehicle is fitted with one, manual border recording is not required even if the driver is still using an older card.
From 1 July 2026 the net widens. A smart tachograph version 2 must be fitted into goods vehicles with a gross weight of 2,501 kg or over - measured including any trailer or semi-trailer - when they are used on international journeys for hire and reward. For general haulage and express freight, that catches vehicles which have historically sat outside the tachograph routine: larger panel vans, 3.5-tonne vans, and van-and-trailer combinations on European work.
Once such a vehicle is in scope for UK-EU hire-or-reward work, it comes under the assimilated drivers' hours rules and the driver must be able to produce the full 56-day record set, exactly as an HGV driver would. Two limits are worth knowing:
Fitting and calibration must be done by an approved tachograph centre, and booking lead times can run to several weeks - so if you run vans on cross-Channel hire-or-reward work, do not wait until the first load is booked to discover the vehicle has no usable record trail.
Build this into the international job-release process, so the decision is made in the traffic office - not at the yard gate, and certainly not at the port. Before you allocate an international load:
Whoever makes that call does not need to be a lawyer. They do need a reliable prompt in the planning system that flags UK-EU work before allocation.
A short check before release prevents most port-side problems:
Most failures are not caused by the international driving day itself. They are caused by the days before it, and by management systems rather than drivers:
The driver produces the records, but the operator decides the work, provides the equipment, and should know whether the driver's record set is fit for the job.
The 56-day rule is a roadside production rule. It does not change your download intervals. Driver cards must still be downloaded at least every 28 days and vehicle units at least every 90 days, with records kept for at least a year for enforcement.
That creates a practical trap: a 28-day card-download cycle can be perfectly legal for downloading, yet it does not by itself prove the driver can produce a complete 56-day record set at a UK-EU roadside check. International haulage needs both - the office download routine and the cab-side production trail.
This article is written for goods haulage, but if you also run a coach or minibus side, the passenger position is deliberately different. PSVs on international UK-EU journeys operate under AETR, not the assimilated rules, so their record-carrying stays at 28 days, and they sit outside the new smart-tachograph-2 light-goods requirements above.
Do not copy the HGV 56-day rule across to the coach side, and do not copy the PSV answer back to haulage. The two are intentionally out of step.
The driver must produce the records on demand. The drill is the same whichever rule set applies: have the card, the printouts or downloaded data, and any charts ready and in order, covering the full carried period - 56 days for UK-EU work, 28 for AETR.
Penalties for missing records are not trivial - fixed penalties, court action, and consequences that can reach the operator's licence - and a gap invites follow-up enquiries that pull in the office as well as the cab. Enforcement abroad can also be stricter on interpretation than you are used to at home, which is the whole reason for keeping clean, complete daily records on international work.
