UK Driver Hours in 2025: AETR, Smart Tachographs and What Changes Now

If you run trucks across borders, manage a fleet, or sit behind the wheel of an HGV for a living, 2025 has brought a handful of changes you genuinely need to know about. From a significant legal shift in how international driver hours are governed, to new tachograph hardware deadlines and tougher record-keeping rules, the compliance landscape has moved on. Here's a clear breakdown of what's changed, what's staying the same, and what you need to do about it.

The Big April 2025 Shift: AETR Rules for International Routes

The most important change this year came into effect on 21 April 2025. For HGV operators running international routes, the legal framework governing driver hours has moved away from retained EU regulations and onto the AETR — the European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport.

This matters most if your drivers are travelling between the UK and non-EU countries, or transiting through the EU to reach AETR signatory nations.

On the surface, the core limits look familiar:

• Daily driving: 9 hours (extendable to 10 hours twice a week)
• Weekly driving: 56 hours maximum
• Fortnightly limit: 90 hours across two consecutive weeks

So far, so similar. But the AETR rules come with some meaningful differences in the detail. Certain EU-specific exemptions — including some that allowed drivers more flexibility around returning home — are no longer available under AETR. Rest period rules also differ in specific circumstances, so if your team has been relying on those exemptions, it's worth revisiting your route planning and scheduling now.

The practical advice here is straightforward: if any of your vehicles cross international borders, make sure your transport managers are working from the AETR ruleset, not the old retained EU framework.

56 Days of Records: The New Roadside Requirement

This one catches people out. As of 2025, drivers on international routes must be able to produce 56 days of tachograph records at the roadside — that's double the previous 28-day requirement.

This applies to digital data, analogue charts, and any manual entries made during that period. At a roadside check, enforcement officers can ask for the full 56-day window, and if your driver can't produce it, the fines can be significant.

For operators, this means your back-office systems need to be storing and retrieving data across that extended window without a hitch. Whether you're using tachograph analysis software or a broader fleet compliance platform like TruckCheck, make sure your setup actually covers the full 56 days and that drivers know how to access and present that data if they're stopped.

Don't leave this until a driver is standing at the roadside with an enforcement officer asking questions.

Smart Tachograph Version 2: Deadlines You Cannot Miss

The tachograph upgrade programme has been running for a while, but 2025 brings the deadlines that operators of older units have been working toward — and the timelines are tight.

August 18, 2025: The Main Retrofit Deadline

Any vehicle over 3.5 tonnes operating internationally that is currently fitted with a Smart Tachograph 1 (or older analogue/digital units) must be retrofitted with Smart Tachograph Version 2 (STV2) by this date. That's not a soft target — it's a legal requirement for international operations.

July 1, 2026: Light Goods Vehicles

From this date, light goods vehicles between 2.5 and 3.5 tonnes on international routes will also require STV2. If you operate smaller vehicles on cross-border work, this deadline should already be in your planning calendar.

What Does STV2 Actually Do?

Beyond the compliance box-ticking, STV2 brings some genuinely useful functionality. It automatically records GPS data at border crossings and logs loading and unloading activity. This is directly tied to enforcement of cabotage rules and posted worker regulations — two areas where enforcement has been increasing.

In practical terms, if your driver crosses a border, the tachograph records it automatically. There's less room for ambiguity, and less burden on the driver to manually log everything correctly. But it also means there's nowhere to hide if something goes wrong, so accurate scheduling and proper rest planning matter more than ever.

Domestic Rules and a Tougher Enforcement Climate

For drivers working exclusively within the UK, the core rules haven't changed. The standard limits remain:

• Daily driving: 9 hours, extendable to 10 hours twice a week
• Weekly limit: 56 hours
• Daily rest: 11 hours, reducible to 9 hours up to three times a week

What has changed is the enforcement approach. The DVSA has stepped up roadside spot checks and is now using remote tachograph monitoring to flag potential rest period breaches before a vehicle is even pulled over. They've been clear that there is a zero-tolerance stance on fatigue-related violations, with faster penalty processes for breaches identified through remote sensing.

Transport managers should note that the DVSA Earned Recognition audit standards for HGV operators set out exactly what compliance looks like in practice — including expectations around tachograph analysis, driver briefings, and infringement management. If your processes can withstand that level of scrutiny, you're in a strong position. If not, now is a good time to tighten things up.

A Quick Word on the Driver Workforce in 2025

The UK added around 36,000 HGV drivers between Q4 2023 and Q4 2024, bringing the active workforce to somewhere between 261,000 and 280,000. That's encouraging, but vacancy rates are still sitting at around 26%, and nearly half of all drivers are over 50. The pipeline is improving, but it's still stretched.

CPC training is also being modernised, with pilots for digital-first, more flexible learning modules expected to roll out further through 2025. For operators, that's worth keeping an eye on — more accessible training options could help with recruitment and retention.

In a workforce this tight, losing a driver to a licence suspension over a preventable hours breach is a costly mistake. Getting your compliance processes right protects your drivers as much as it protects your operator licence.
