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

If you run HGVs in the UK, 2025 has brought some of the most significant changes to driver hours rules in years. The Drivers' Hours and Tachographs (Amendment and Modification) Regulations 2025, which came into force on 21 April 2025, have reshaped how operators and drivers must approach compliance — particularly for international work. Whether you're a transport manager juggling rotas, a haulage company owner trying to stay on the right side of the DVSA, or a driver who wants to know exactly where you stand, this post breaks down what's changed, what hasn't, and what you need to do right now.

What's Actually Changed in 2025

From "EU Rules" to "Assimilated Rules"

The first change is largely about terminology, but it matters for accuracy. What were previously referred to as "EU rules" or "retained EU law" in the context of driver hours are now formally called Assimilated Rules in UK legislation. If you're updating your compliance documentation, transport policies, or driver handbooks, make sure you're using the correct term — it will matter during audits.

AETR Rules Now Apply to International Journeys

The bigger shift is operational. The UK has formally adopted AETR rules (European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport) for all international journeys under the UK/EU Trade and Cooperation Agreement (TCA). This has practical consequences — not just legal ones.

Two flexibilities that drivers and operators sometimes relied on are now off the table for international work:

• Drivers cannot use "unforeseen events" allowances to exceed driving limits in order to reach home for their weekly rest period.
• Reduced weekly rest must be compensated at a fixed location — you can no longer take compensatory rest in the cab of the vehicle.

If your drivers regularly cross into Europe or operate under AETR, your risk assessments and driver briefings need to reflect these restrictions right away.

The 56-Day Record Rule: A Major Change for International Drivers

This is the one that's catching operators out. As of April 2025, drivers on international journeys must be able to produce 56 days of tachograph records at the roadside — that's the current day plus the previous 55 days. Previously, the requirement was 28 days.

That's a 100% increase in record-keeping obligations overnight.

In practice, this means:

• Drivers need to carry significantly more data on their driver card and/or printouts
• Fleet operators need systems that store and can quickly retrieve up to eight weeks of data per driver
• If a driver is stopped at the roadside and can't produce the full 56-day history for international work, they're exposed to fines for historical breaches

The DVSA has made clear it will enforce this strictly, and with increased use of remote tachograph monitoring technology, spot checks are becoming more targeted. This is exactly the kind of ongoing compliance task that benefits from a structured digital system — something like TruckCheck is built to help operators manage and retrieve driver records quickly without scrambling through paperwork.

Smart Tachograph Version 2: Don't Miss the August Deadline

If you run HGVs over 3.5 tonnes on international routes and they're currently fitted with a Version 1 Smart Tachograph, you have until 18 August 2025 to retrofit them with Smart Tachograph Version 2 (SMT2).

This is a firm deadline — not a guideline. Vehicles that haven't been upgraded and are used for international transport after this date will be non-compliant.

SMT2 units offer enhanced security features and better interoperability with enforcement systems across borders. The retrofit process takes time to book in, and with many operators across the UK and Europe needing the same work done before the same deadline, tachograph calibration centres are getting busy. If you haven't already spoken to your preferred tachograph centre, do it now.

It's also worth noting that 1 July 2026 brings another tachograph deadline: light goods vehicles between 2.5 and 3.5 tonnes used on international routes will need to be fitted with tachographs for the first time. If you operate any vehicles in that weight bracket on cross-border work, start planning ahead.

Domestic Rules: What Hasn't Changed

For drivers operating strictly within Great Britain, the core driver hours limits remain the same. These are worth restating clearly:

• Daily driving: 9 hours, extendable to 10 hours a maximum of twice per week
• Weekly driving: No more than 56 hours
• Fortnightly driving: No more than 90 hours across two consecutive weeks
• Breaks: 45 minutes after no more than 4.5 hours of driving — this can be split into a 15-minute break followed by a 30-minute break

These limits are well-established, but the DVSA's Earned Recognition audit standards for HGV operators make clear that operators are expected to have robust systems in place to monitor driver hours proactively — not just react to infringements after the fact. If you're working towards Earned Recognition or simply want to demonstrate good compliance culture, your analysis and record-keeping processes need to be consistent and auditable.

Other Developments Worth Watching

A couple of other changes are moving through the system in 2025:

Digital medical renewals: The DVLA is piloting a digital-first medical renewal system for drivers aged 45 and over. The aim is to phase out paper self-declarations by late 2025, which should reduce the delays that have caused some licence renewal headaches. Worth keeping an eye on if you have older drivers in your fleet.

Scotland HGV speed limits: Discussions are ongoing about raising the HGV speed limit on single carriageways in Scotland from 40mph to 50mph, bringing it in line with England and Wales. Nothing is confirmed yet, but it's a change that could affect journey planning and driver hours calculations if it goes through.

Make Sure Your Compliance Is Ready

2025 has raised the bar, and the DVSA is enforcing it. Between the doubled record-keeping requirements, the SMT2 retrofit deadline, and the AETR changes for international work, there's a lot to stay on top of. The operators who handle this well are the ones with clear processes, well-briefed drivers, and systems that make compliance visible day to day — not just at audit time.

TruckCheck is designed to help UK haulage operators do exactly that — keeping records, monitoring hours, and staying ahead of deadlines without the admin burden.
