UK Driver Hours Rules 2025: What Every Haulage Operator Must Know

If you run HGVs on UK roads — whether you're an owner-operator with two trucks or a transport manager overseeing a large mixed fleet — 2025 has brought a stack of regulatory changes that genuinely matter. Some affect international runs, some affect your paperwork, and at least one affects the kit bolted to your cab. Miss any of them, and you're looking at fixed penalties, vehicle prohibitions, or worse, a trip to the Traffic Commissioner. Here's a plain-English breakdown of everything you need to know.

The Biggest Change: AETR Rules Now Govern International Journeys

From 21 April 2025, the legal framework covering driver hours for journeys between the UK and non-EU countries — and certain UK-EU transits — shifted from what is now officially called the "assimilated drivers' hours rules" (the retained EU rules carried over after Brexit) to the AETR (European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport).

In practical terms, this matters because AETR is less flexible. Here's what changes for international operations:

Weekly Rest — Less Room to Manoeuvre

Under the old EU-derived rules, there were provisions allowing drivers to interrupt or delay weekly rest in certain circumstances — particularly the "return-to-base" flexibility. Under AETR, that's largely gone.

Drivers can still take a reduced weekly rest (less than 45 hours), but crucially, only one reduced rest is permitted at a time, and it must be immediately followed by a full 45-hour weekly rest. No stacking reduced rests. No creative scheduling to make a tight international run work on paper.

If your planners have been relying on that EU flexibility to build international rotas, those schedules need revisiting now.

What Counts as an "International Journey"?

This is worth clarifying with your traffic team. The AETR rules apply to journeys between the UK and countries outside the EU, and in some cases to transits involving EU member states. If your operation runs any cross-border work — even occasionally — you need to be certain which ruleset applies to each job. When in doubt, apply the stricter standard.

The 56-Day Rule: Double the Records, Double the Responsibility

This one catches people out, and it came into effect immediately in April 2025.

Any driver undertaking an international journey must now be able to produce 56 days of tachograph records — that's the current day plus the previous 56 calendar days. That's double the previous 28-day requirement.

Those records must cover:

• Digital tachograph data from the driver card and vehicle unit
• Analogue charts, where applicable
• Manual entries for any periods not recorded by the vehicle unit (rest at home, days off, time in a non-tachograph vehicle, etc.)

The DVSA can and does check these at the roadside. An infringement — whether that's missing records or incomplete manual entries — can result in a fixed penalty of £300 per offence. That adds up fast if a driver is found short across multiple days.

For transport managers, this means your record-retention systems need an immediate audit. If you're storing driver card data manually or relying on drivers to carry physical records, 56 days is a significant volume. Tools like TruckCheck that automatically pull and store tachograph data become less of a nice-to-have and more of an operational necessity at this kind of retention requirement.

The DVSA's own Earned Recognition audit standards for HGV operators set a clear expectation that operators maintain accurate, accessible driver hours records — the 56-day rule simply raises the bar on what "accessible" actually means.

Smart Tachograph Version 2: Deadlines You Cannot Miss

If you haven't already started planning your SMT2 upgrades, you need to be moving now. The DVSA has set two hard deadlines:

18 August 2025 — Smart Tachograph 1 Vehicles

Any vehicle currently fitted with a Smart Tachograph Version 1 that is used for international transport must be retrofitted with SMT2 by this date. That's a matter of weeks away. Workshop slots for tachograph calibration and installation are already booking up — don't leave this until the last minute.

1 July 2026 — Light Commercial Vehicles (2.5–3.5 Tonne GVW)

Vans and light commercials with a gross vehicle weight between 2.5 and 3.5 tonnes that are involved in international transport must be fitted with SMT2 by this date. If you run a mixed fleet with smaller vehicles crossing borders, plan this upgrade into your maintenance schedule now rather than scrambling next year.

SMT2 improves remote roadside enforcement capabilities, which means DVSA officers can pull more data faster. That's all the more reason to make sure your records are clean before the technology upgrade forces the issue.

UK Domestic Rules and a Welcome Update for Electric Fleets

Here's some straightforward good news: domestic rules haven't changed. For journeys taking place entirely within Great Britain, the standard limits still apply:

• 9 hours of daily driving (extendable to 10 hours, but no more than twice per week)
• 45-minute break after 4.5 hours of driving (which can be split as 15 minutes followed by 30 minutes)
• 11 hours of daily rest (reducible to 9 hours, but no more than three times between weekly rests)

Keep it straightforward for domestic-only drivers and planners — the complexity sits squarely in the international operations side.

Zero-Emission Vehicles: New Weight Allowance from June 2025

From 10 June 2025, drivers holding a standard Category B licence can operate zero-emission vehicles (ZEVs) weighing up to 4.25 tonnes without needing the additional five hours of training that was previously required. This is a deliberate move to remove friction from electric fleet adoption, and it's useful if you're transitioning last-mile delivery operations to electric vans.

What You Should Be Doing Right Now

To stay on the right side of the DVSA in 2025, here's a practical checklist:

1. Review all international schedules against AETR rules — particularly weekly rest planning
2. Audit your tachograph data retention to confirm you can produce 56 days of records at roadside
3. Book SMT2 retrofits for any SMT1 vehicles used internationally before 18 August 2025
4. Brief your drivers on the new requirements — especially the extended record-carrying obligation
5. Check your operator licence conditions and consult your Traffic Commissioner region if anything is unclear

Compliance isn't just about avoiding fines. A solid record of hours compliance is central to maintaining your operator's licence, and the DVSA's Earned Recognition scheme rewards operators who demonstrate consistent, auditable standards.
