2025 UK HGV Hours Rules: What Every Transport Manager Must Know Now

If you run HGVs on international routes, manage a mixed fleet, or simply want to stay on the right side of the DVSA in 2025, the last few months have brought changes you genuinely need to act on. The Drivers' Hours and Tachographs (Amendment and Modification) Regulations 2025 came into full effect on 21 April 2025, and they introduce some of the most significant shifts to driver hours compliance we've seen in years. This isn't a box-ticking exercise — get it wrong and you're looking at serious penalties, potential operator licence risk, and vehicles being pulled off the road at the roadside.

Here's what's changed, what hasn't, and what you need to do about it.

The Big One: 56-Day Tachograph Records Are Now Required

This is the change that's catching operators off guard the most. Previously, drivers on international operations needed to carry 28 days of tachograph records for roadside inspection. As of April 2025, that window has doubled to 56 days — meaning the current day plus the previous 55 days of records.

This applies to:

• Digital tachograph data
• Analogue charts
• Manual entries (for any days not covered by a tachograph)

What this means in practice

Drivers need to be able to produce two months' worth of evidence at a roadside check. That's a significant administrative uplift. If your drivers cross into Europe regularly, your record-keeping processes need to be watertight well before they hit the road.

For transport managers, this means your document retrieval process needs to work faster and further back. Using a digital system to store and access tachograph data — like TruckCheck — makes this kind of retrospective check far less painful than digging through paper charts or chasing drivers for USB downloads.

The DVSA Earned Recognition audit standards are clear that operators must demonstrate effective tachograph analysis and record retention. The shift to 56-day requirements reinforces why this can't be an afterthought.

AETR Rules Now Apply to International Routes Outside the EU

Another significant change: for journeys between the UK and non-EU countries — including those that transit through the EU to get there — the UK has formally adopted AETR rules (the European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport).

Why this matters

Under previous retained EU law, UK drivers had access to certain flexibilities — including a "return to home" exemption — that don't exist under AETR. Now that AETR applies, those flexibilities are gone for applicable international routes.

Practically speaking, this affects:

• Rest period rules, which are more prescriptive under AETR
• Split rest arrangements, which are handled differently
• Drivers who may have been used to applying domestic or EU-style flexibility on these routes

If your drivers are running to Turkey, the Middle East, or other non-EU destinations, make sure they've been briefed on the specific AETR requirements. Assuming EU rules apply when they don't is an easy mistake — and an expensive one.

Smart Tachograph Version 2: The August Deadline You Can't Miss

By 18 August 2025, any HGV over 3.5 tonnes operating internationally that currently runs Smart Tachograph Version 1 must be retrofitted with Smart Tachograph Version 2.

What's new with Smart Tacho 2?

• Automatic border crossing recording — the device logs when a vehicle crosses an international boundary, removing reliance on manual entries
• Enhanced GPS tracking — significantly harder to tamper with or manipulate
• Improved fraud detection capability for enforcement agencies

The DVSA has been ramping up remote tachograph monitoring in 2025, allowing inspectors to detect rest period breaches and potential record tampering while vehicles are still moving. Smart Tacho 2 feeds directly into that enforcement capability.

If you haven't already started your retrofit programme, August is closer than it feels. Tachograph calibration centres are already reporting increased demand. Book early.

Domestic Rules Haven't Changed — But Don't Get Complacent

For drivers operating entirely within the UK, the core hours rules remain the same:

• Daily driving: 9 hours (extendable to 10 hours, maximum twice a 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 15 + 30)
• Daily rest: 11 hours (reducible to 9 hours up to three times between weekly rests)

The fact that domestic rules are unchanged doesn't mean enforcement has eased off. The DVSA has confirmed it's increasing enforcement activity across the board in 2025, and fatigue remains one of the most serious risks in the industry. Estimates suggest 10–20% of HGV collisions involve driver tiredness — which is exactly why these regulations exist.

Scotland speed limit change on the horizon

One additional update worth noting: Scotland is expected to align its HGV single-carriageway speed limit (currently 40mph) with the 50mph limit in England and Wales by late 2025. It's not a hours rule, but it's worth keeping on your radar for driver briefings.

What Transport Managers Should Do Right Now

To summarise, here's a practical action list:

1. Audit your record-keeping systems — can you retrieve 56 days of tachograph data quickly and cleanly for any driver on an international run?
2. Review your international route briefings — make sure drivers understand AETR requirements and how they differ from EU or domestic rules
3. Book Smart Tachograph 2 retrofits immediately — don't leave this until July
4. Check your compliance processes against DVSA standards — the Earned Recognition audit standards are a useful benchmark even if you're not in the scheme
5. Brief your drivers — they're the ones who'll be at the roadside when an inspector asks for 56 days of records

Tools like TruckCheck can help you stay on top of digital tachograph analysis, flag compliance issues before they become DVSA problems, and keep your records in order without the admin overhead.

Staying compliant in 2025 takes more than good intentions — it takes good systems.
