UK HGV Compliance in 2025: Driver Hours, Tachographs and What's Changed

Keeping on top of HGV compliance in the UK has never been the simplest job, and 2025 has brought a fresh batch of changes that every haulage company owner, transport manager, and driver needs to know about. From updated record-keeping requirements at the roadside to hard deadlines for tachograph upgrades, there's quite a bit to get your head around. This post breaks it all down in plain English — no legal jargon, just the stuff that matters for day-to-day operations.

What's Changed in 2025: The DVSA Updates You Need to Know

The DVSA's updated drivers' hours rules came into effect on 21 April 2025, and while some of the changes are largely administrative, others have real operational impact — particularly for operators running international routes.

The 56-Day Record Requirement

This is probably the most significant practical change for drivers crossing borders. Previously, drivers on international journeys needed to carry 28 days of records for roadside checks. From April 2025, that requirement has doubled to 56 days.

That means drivers need to have records going back nearly two months readily available — either on their tachograph card or as printed downloads. If your drivers are regularly crossing into Europe or travelling to non-EU countries, now is the time to make sure your record management process is watertight. Getting caught at a roadside check without the right documentation can mean fixed penalty notices and serious delays.

AETR Rules for Non-EU International Journeys

For journeys between the UK and non-EU countries, operators must comply with the AETR (the European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport). This is a separate framework to the standard assimilated rules, and it's worth double-checking which rules apply depending on the route your drivers are running.

Goodbye "EU Law" — Hello "Assimilated Drivers' Hours Rules"

This one is more about language than practice, but it matters. All official DVSA guidance has now replaced references to "EU law" with "assimilated drivers' hours rules" to reflect the post-Brexit legal position. If you're updating your internal policies, driver handbooks, or compliance documentation, make sure you're using the correct terminology — it keeps things clean if you're ever subject to an audit or enforcement check.

The updated guidance also clarifies the definition of "goods" in the context of drivers' hours, refines certain national derogations (including exemptions for radio and TV broadcasting vehicles), and revises country classification lists. It's worth a read if your operation touches any of these areas.

Smart Tachograph 2: Retrofit Deadlines Are Coming Fast

If there's one thing operators shouldn't be putting off right now, it's getting their tachograph situation sorted. The Smart Tachograph version 2 (SMT2) retrofit deadlines are approaching quickly, and missing them for international work isn't an option.

• 18 August 2025: Vehicles used on international journeys that currently have a Smart Tachograph 1 must be retrofitted with SMT2 by this date.
• 1 July 2026: Light commercial vehicles and vans with a GVW between 2.5 and 3.5 tonnes used for international commercial transport must also be fitted with SMT2 units.

SMT2 units offer improved remote enforcement capabilities, better data integrity, and enhanced satellite positioning. For operators with a mixed fleet, it's worth auditing which vehicles are running which tachograph version now — don't leave it until August and find yourself scrambling for workshop slots.

The Core Rules That Haven't Changed (But Still Catch People Out)

While the 2025 updates have focused on international compliance and documentation, the fundamental drivers' hours limits remain the same under the UK's assimilated rules. That said, they're still the source of most compliance failures — so here's a quick refresher.

Daily and Weekly Driving Limits

• Daily limit: 9 hours of driving, extendable to 10 hours twice a week
• Weekly limit: No more than 56 hours in a single week
• Fortnightly limit: No more than 90 hours across any two consecutive weeks

Breaks and Rest Periods

• A 45-minute break is required after no more than 4.5 hours of cumulative driving — this can be split into a 15-minute break followed by a 30-minute break, in that order
• Daily rest is normally 11 consecutive hours, which can be reduced to 9 hours up to three times between weekly rests
• Weekly rest requires at least 45 unbroken hours (reducible to 24 hours under certain conditions, with any reduction compensated later)

Working Time Directive

Don't forget the Working Time Directive sits alongside drivers' hours rules. The WTD limits drivers to a maximum of 60 hours in a single week, with an average of no more than 48 hours per week calculated over the reference period. These are separate obligations — you need to be tracking both.

The DVSA's Earned Recognition audit standards for HGV operators set out exactly what's expected when it comes to monitoring drivers' hours and tachograph compliance. If you're aiming for Earned Recognition status — or just want a clear benchmark for your own systems — it's genuinely useful reading.

How to Stay on Top of It All

The honest truth is that compliance only gets harder as your fleet grows. Keeping track of 56 days of records per driver, monitoring tachograph versions across multiple vehicles, and staying current with rule changes is a lot to manage manually.

Tools like Fleet77 are built specifically for this — giving transport managers a clear view of driver hours, tachograph data, and compliance status in one place, so you're not piecing things together from spreadsheets and printouts the night before an audit.

The key habits that keep operators compliant are pretty straightforward: download tachograph data regularly, act quickly on any infringements, keep driver records up to date, and make sure your team actually understands the rules they're working to.

The 2025 changes aren't the most dramatic overhaul the industry has ever seen, but they do raise the bar — especially for anyone running international routes. Get the documentation right, sort your tachograph retrofits before the August deadline, and keep the core rules front of mind.
