UK Driver Hours Rules 2025: What Hauliers Must Do Now

If you run HGVs in the UK, 2025 is a year you need to pay close attention to. A raft of regulatory changes came into force on 21 April 2025, affecting everything from how many days of records your drivers need to carry, to what tachograph hardware you're legally required to have fitted. Whether you're a transport manager juggling a fleet of 30 vehicles or an owner-driver doing international runs, these updates affect you directly — and the consequences of getting it wrong can be serious.

Here's a practical breakdown of what's changed, what's coming, and what you should be doing right now.

The 56-Day Record Rule: A Big Change for International Operators

One of the most significant changes is the extension of the records production requirement for international journeys. Previously, drivers needed to be able to produce 28 days of records at the roadside. From 21 April 2025, that figure has doubled to 56 days.

This applies to all record types — digital tachograph data, analogue charts, and any manual entries. So if your driver gets pulled over during a cross-border run, enforcement officers can legally request up to two months' worth of data on the spot.

What this means in practice

• Drivers need access to, or must carry, a full 56-day record set for international work
• Your back-office systems need to store and retrieve tachograph data going back further than before
• Any gaps, missing charts, or corrupted data over that extended window are now a compliance risk

If you're using a system like Fleet77 to manage your tachograph downloads and driver records, now is a good time to check your data retention settings and make sure everything is being captured and stored correctly across that full 56-day window.

AETR Rules Now Apply to Non-EU International Journeys

Post-Brexit compliance has another layer added to it. Operators running vehicles to and from the UK and non-EU countries must now follow AETR rules — the European Agreement concerning the Work of Crews of Vehicles engaged in International Road Transport.

This is separate from the domestic "assimilated drivers' hours rules" (more on that term below) and applies specifically to international routes that pass through or terminate in non-EU countries. The practical effect is that your hours rules, rest requirements, and record-keeping obligations may differ depending on where your vehicle is going — and drivers and transport managers need to know the difference.

If your fleet does any international work outside the EU, it's worth revisiting your route planning and driver briefing processes to make sure the right rules are being applied to the right journeys.

Smart Tachograph 2: Retrofit Deadlines You Can't Ignore

The DVSA has set firm deadlines for retrofitting Smart Tachograph 2 (ST2) devices. These aren't recommendations — they're legal requirements with clear cut-off dates:

• 18 August 2025 — Vehicles currently fitted with a Smart Tachograph 1 (ST1) must be retrofitted with ST2
• 1 July 2026 — Vehicles with a Gross Vehicle Weight between 2.5 and 3.5 tonnes must also have ST2 fitted

Why this matters now

The August 2025 deadline is only weeks away for many operators reading this. If you have vehicles running ST1 tachographs and you haven't already booked them in for retrofit, you need to act immediately. Approved tachograph centres are already reporting increased demand, and leaving it until the last minute risks your vehicles being non-compliant and potentially off the road.

Smart Tachograph 2 brings improved remote enforcement capabilities, meaning DVSA officers can interrogate your tachograph data from the roadside without the driver having to hand anything over manually. Keeping your tacho hardware current isn't just about compliance — it also reduces the chance of getting tied up in lengthy roadside checks.

Terminology and Guidance Updates: What's Actually Changed

The DVSA has also updated its official guidance to reflect the post-Brexit legal reality. The most visible change is linguistic: references to "EU law" throughout the guidance have been replaced with the term "assimilated drivers' hours rules." This matters because it signals that while the substance of the rules largely mirrors what existed under EU regulation, they now sit within UK domestic law.

Beyond the terminology, several other clarifications have been made:

• Definition of "goods" — A formal definition has been added to clear up ambiguity about what counts as goods under drivers' hours rules
• Derogations for broadcasting — Rules around national derogations for radio and television broadcasting vehicles have been clarified
• Country classifications — The lists of EU and non-EU countries have been updated to ensure operators are applying the right rules to the right routes
• Regulatory scope — There's now a clearer breakdown of which regulations govern drivers' hours versus working time, which has historically caused confusion

These might sound like housekeeping changes, but they matter for compliance audits. The DVSA's Earned Recognition scheme, for example, holds operators to a high standard of documented compliance — and if your policies or training materials reference outdated terminology or misclassify your operating territory, that could flag during an audit. You can check the current DVSA Earned Recognition audit standards for HGV operators to make sure your processes align.

What You Should Be Doing Right Now

To summarise, here's a practical checklist for operators:

1. Check your tachograph hardware — If you have ST1 devices, book retrofits immediately. Don't wait until August
2. Update your record retention — Ensure you're storing 56 days of records for drivers doing international work
3. Brief your drivers — Make sure they understand the 56-day production requirement and what they need to carry or have accessible
4. Review international routes — Confirm whether AETR rules apply to any of your cross-border work
5. Update internal policies — Replace references to "EU law" with "assimilated drivers' hours rules" and check your definitions align with the updated DVSA guidance
6. Check your exemptions — If you operate vehicles that may fall under national derogations or specific exemptions, verify these are still correctly applied

Staying on top of driver hours compliance isn't just about avoiding fines — it's about protecting your operator licence, your drivers, and your business. The rules are there for road safety reasons, and enforcement isn't slowing down.
