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

If you run a haulage business or sit behind the wheel of an HGV for a living, 2025 brought more paperwork, more deadlines, and more things to keep on top of than most years in recent memory. The regulatory landscape shifted in ways that matter — from how long drivers need to carry tachograph records on international runs, to when your vehicles need upgraded tachograph hardware. Some changes are administrative tidying-up post-Brexit; others have real operational consequences if you miss them. Here's what you need to know.

The Big One: International Routes Now Follow AETR Rules

The most significant change of the year landed on 21 April 2025, when the UK formally adopted the AETR framework (European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport) for international haulage operations. This replaced what was previously known as the "retained EU" rules.

In plain terms, if your drivers are crossing borders — into Europe, or further afield — they're now operating under AETR, not a version of old EU law. The practical impact is real.

The 56-Day Record Requirement

One of the most immediately noticeable changes is the 56-day tachograph record rule. Drivers on international routes must now be able to produce records covering the current day plus the previous 55 days — that's double the old 28-day requirement.

This applies across the board: digital tachograph data, manual entries, and analogue charts all count. If a driver is stopped at a roadside check and can't produce the full 56 days of data, that's a potential £300 fine per offence, with a maximum of £1,500 in a single inspection.

For fleet operators, this means your record-keeping processes need to be watertight. You can't afford gaps, lost cards, or missing printouts. It's the kind of thing that fleet compliance tools — TruckCheck included — are built to help you stay on top of, by giving you a clear audit trail of driver data.

Domestic Rules: Same Limits, New Name

If you're running purely domestic operations, the core hours limits haven't changed. But there is a terminology shift worth knowing about.

What used to be called "EU drivers' hours rules" within the UK is now officially referred to as "assimilated drivers' hours rules." It's a post-Brexit rebranding that reflects the UK's legal independence from EU frameworks. The rules themselves remain the same, but you may start seeing this new language in DVSA communications, operator audits, and legal documentation.

A Quick Refresher on the Core Limits

Just so everyone's on the same page:

• Daily driving: 9 hours, extendable to 10 hours a maximum of twice per week
• Weekly limit: 56 hours
• Fortnightly limit: 90 hours across any two consecutive weeks
• Breaks: 45 minutes after 4.5 hours of driving (can be split into a 15-minute break followed by a 30-minute break)
• Daily rest: 11 hours, reducible to 9 hours up to three times between weekly rests

These are non-negotiable. The DVSA's Earned Recognition audit standards make clear that operators are expected to have robust systems in place to monitor compliance with these limits — and that means not relying on memory or spreadsheets.

Tachograph Hardware: The SMT2 Deadline You Cannot Miss

If your vehicles are currently fitted with a Smart Tachograph Version 1 (SMT1), you need to be aware of a critical retrofit deadline.

From 18 August 2025, all HGVs using SMT1 units must be upgraded to Smart Tachograph Version 2 (SMT2) for international work. SMT2 units offer improved satellite positioning accuracy and enhanced remote enforcement capabilities — meaning roadside inspectors can access more data, more quickly.

Missing this deadline for international trips isn't just a compliance risk; it could mean your drivers are turned back at the border or hit with enforcement action.

There's a separate deadline for smaller vehicles in the 2.5–3.5 tonne GVW range, which have until 1 July 2026 to comply. But if you're running full HGVs on European routes, August 2025 is your line in the sand.

Book your retrofits now if you haven't already — tachograph installers are in high demand, and leaving it to the last minute is a risk you don't need.

Electric HGVs: Changing Rules for a Growing Fleet

Zero-emission HGVs are becoming harder to ignore. UK registrations of electric heavy goods vehicles grew by 34% between 2024 and 2025, and while the total number — around 1,000 vehicles — is still a small fraction of the UK's 534,000-strong HGV fleet, the direction of travel is clear.

The rules around who can drive them have also been updated. From 10 June 2025, Category B (standard car) licence holders can drive zero-emission vehicles weighing up to 4.25 tonnes GVW — up from the previous 3.5-tonne limit — without needing the five hours of additional training that was previously required.

This opens up lighter electric commercial vehicles to a much wider pool of drivers, which is useful news for last-mile operators or businesses running smaller refrigerated or distribution vehicles. It won't affect most traditional HGV operators directly, but it's worth understanding as your fleet strategy evolves.

Enforcement Is Getting Sharper

The DVSA has continued to ramp up roadside activity, with a growing focus on digital enforcement. Inspectors are better equipped than ever to pull data quickly from modern tachographs, cross-reference it against records, and identify discrepancies on the spot.

Fines remain at £300 per offence, capped at £1,500 per inspection — and with the 56-day record requirement now in force for international drivers, the chances of inspectors finding something if records aren't in order have increased considerably.

Operators signed up to the DVSA Earned Recognition scheme are expected to demonstrate consistent, evidenced compliance. Using a digital fleet management tool like TruckCheck makes it significantly easier to maintain that evidence — with records stored, accessible, and ready when you need them.

Stay Ahead, Not Behind

The UK haulage industry is navigating a period of genuine change — new rules, new technology, and growing enforcement pressure, all at the same time as dealing with a driver shortage that's still biting. With vacancy rates sitting at around 26% by the end of 2025, operators need their existing drivers compliant, their vehicles roadworthy, and their paperwork in order.

Getting your head around the 2025 updates isn't optional. The AETR switch, the SMT2 retrofit deadline, and the 56-day record rule all have direct consequences for operators who fall short.
