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

If you run a haulage business, manage a transport operation, or get behind the wheel of an HGV for a living, 2025 is shaping up to be one of the busiest years for compliance changes in recent memory. Between new tachograph technology mandates, updated record-keeping requirements, and tighter enforcement on the roads, there's a lot to keep on top of. This post breaks it all down in plain English so you know exactly where you stand.

The 56-Day Record Requirement: A Big Change From April 2025

One of the most immediate changes you need to know about came into effect on 21 April 2025. If your drivers are doing international work — that's any journey between the UK and EU member states, or countries covered by the AETR agreement — they must now be able to produce 56 days of driver records at a roadside inspection. That's double the previous 28-day requirement.

These records cover everything: digital tachograph data, analogue charts where applicable, and any manual entries. The thinking behind it is straightforward — regulators want a longer window to spot patterns of fatigue and rest violations that might not be obvious from a fortnight's worth of data.

In practice, this means your drivers need to be carrying more data, and your back-office systems need to be storing and retrieving it reliably. If you're using a compliance platform like TruckCheck, this kind of automated record archiving is exactly the sort of thing it's built for — but whatever system you're using, make sure it can pull 56 days of clean data at short notice.

AETR Rules: What's Changed for International Operators

Post-Brexit, the UK has shifted its legal basis for international journeys (to and from non-EU countries) to the AETR rules — the European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport. In practice, the core driving limits look familiar, but there are some important differences worth knowing.

Where AETR Is Stricter

• Ferry crossings and rest interruptions: Under the old EU-retained rules, drivers had some flexibility to interrupt rest periods during ferry or train crossings. AETR is stricter here and offers less room for manoeuvre.
• No "returning-to-base" exemptions: Some flexibility previously available under EU-retained law — particularly around returning to base — doesn't apply under AETR.

For purely domestic operations, the rules remain as they were. You still work to the "assimilated drivers' hours rules" — that's the official post-Brexit term for what used to be called EU drivers' hours rules applied within UK law. The limits stay the same: 9 hours daily driving (extendable to 10 hours twice a week), a 45-minute break after 4.5 hours, and a 56-hour weekly maximum.

The key takeaway here is to know which ruleset applies to each journey. Mixed fleets doing both domestic and international work need clear procedures — and drivers need to understand which rules govern their specific run.

Smart Tachograph 2: Don't Miss the August Deadline

If there's one compliance issue that could catch operators off guard in the second half of 2025, it's the Smart Tachograph Version 2 (SMT2) retrofit deadline.

Key Dates to Diary

• 31 December 2024 (already passed): Vehicles used internationally with older analogue or standard digital tachographs should already have been upgraded.
• 18 August 2025: Any vehicle over 3.5 tonnes used for international work that currently has a Smart Tachograph 1 fitted must be retrofitted with SMT2 by this date.
• 1 July 2026: The requirement extends to light commercial vehicles between 2.5 and 3.5 tonnes used for international hire or reward.

Why SMT2 Matters

SMT2 isn't just a hardware upgrade — it changes how enforcement works. These devices offer automatic border detection, enhanced GPS tracking, and crucially, remote sensing capability. That means DVSA officers can check for certain infringements without even pulling you over. If your vehicle is flagged, you may not know until it's too late.

Getting the retrofit done early and making sure it's calibrated correctly is genuinely important. Leaving it to the last few weeks of August is a risk you don't need to take — workshops are already reporting backlogs.

Enforcement in 2025: The DVSA Means Business

The DVSA has been clear that 2025 will see tighter enforcement, with remote tachograph monitoring being used to identify and target high-risk operators before vehicles are even stopped at the roadside. This is a significant shift from reactive enforcement to proactive, data-driven targeting.

What They're Looking For

• Rest period breaches remain the most commonly prosecuted infringement, with on-the-spot fines of £300 per offence.
• "Other Work" recording is increasingly under the microscope. Loading, unloading, and any time spent working outside the cab needs to be correctly logged. Getting this wrong can push drivers over their shift limits on paper, even if the driving hours look fine.

Operators holding DVSA Earned Recognition status will already be familiar with the audit standards set out in the HGV Operator Audit Standards. Those standards provide a solid benchmark for the kind of record-keeping and compliance culture the DVSA expects across the board — Earned Recognition or not.

If you're not already auditing your own tachograph data regularly, now is the time to start. Operators who rely on manual checks or only look at records when something goes wrong are the ones most likely to fall foul of remote enforcement.

National Driver CPC: A Note on Domestic Drivers

One smaller but useful change introduced in late 2024 is the National Driver CPC — a more flexible qualification pathway for drivers who will only ever operate within the UK. It offers an alternative to the full international Driver CPC, reducing the training burden for drivers and operators focused entirely on domestic work. If you have drivers who have no plans to cross borders, it's worth exploring whether the National CPC makes sense for your operation.

Keeping up with all of this — new record requirements, AETR rules, SMT2 deadlines, and tighter enforcement — takes real organisation. Whether you're a sole operator running a couple of trucks or managing a larger fleet, having your compliance in order isn't just about avoiding fines. It protects your licence, your drivers, and your business.
