HGV Hours and Tachograph Rules Every UK Operator Must Know Now

If you run HGVs in the UK, 2025 and early 2026 have thrown a lot at you. Between new international driving rules, tachograph hardware deadlines, and beefed-up DVSA enforcement, there's genuinely a lot to stay on top of — and the consequences of getting it wrong are costly. Whether you're a transport manager building your compliance systems, a haulage owner protecting your operator licence, or a driver trying to stay on the right side of the law, this breakdown covers what's changed, what still applies, and what you need to do about it.

The AETR Switch: What It Means for International Journeys

The biggest regulatory shake-up came on 21 April 2025, when the legal framework governing international HGV journeys changed significantly. UK domestic trips still follow UK-specific rules, but if your drivers cross international borders, they're now operating under AETR (European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport) rules rather than the old retained EU regulations.

For most operators, this sounds like a technicality — but the practical differences matter.

Flexibilities You've Lost

Under the old framework, drivers on international routes could use certain flexibilities that the UK had carried over from EU law. Those are gone. Specifically:

• Drivers can no longer extend driving time slightly to reach home or their base for weekly rest. Under AETR, the limits are the limits.
• Interruptions to weekly rest are no longer permitted, even in genuine unforeseen circumstances that were previously accommodated.

This means your international scheduling needs to be tighter. A driver who's used to having a small buffer to get back to the yard at the end of a long week no longer has that safety net. Transport managers need to build these restrictions into route planning from the start — not treat them as a fallback option.

Tachograph Records: You Now Need 56 Days

If your drivers are stopped for an inspection on an international journey, they need to be able to produce 56 days of tachograph records — that's the current day plus the previous 55 days. This is double the previous 28-day requirement and applies to digital data, analogue charts, and manual entries alike.

In practice, this means:

• Drivers must carry or have access to significantly more data during international trips
• Your back-office record-keeping needs to be organised enough to support this — gaps, missing manual entries, or incomplete downloads will show up quickly
• Fleet software like TruckCheck, which logs and stores driver records centrally, makes meeting this kind of requirement far less stressful

The DVSA's Earned Recognition audit standards for HGV operators make clear that robust tachograph management is a core expectation — not an optional extra. If you're aiming for Earned Recognition status, or simply want to demonstrate a credible compliance system, your record-keeping processes should be watertight.

Smart Tachograph Version 2: The Hardware Deadline You Can't Ignore

A critical hardware deadline passed on 18 August 2025. Any HGV operating internationally that was still fitted with a "Smart Tachograph 1" unit needed to have been retrofitted with a Smart Tachograph Version 2 (SMT2) by that date.

SMT2 units bring two important capabilities:

• Automatic border-crossing registration — the unit logs when a vehicle crosses a border without the driver needing to do anything manually
• Improved GPS tracking — designed to reduce fraud and make enforcement more straightforward for DVSA and equivalent agencies abroad

If you're still running SMT1 units on internationally-operating vehicles, you're already in breach. Get those retrofits sorted immediately.

What About Lighter Vehicles?

There's a separate deadline for vehicles between 2.5 and 3.5 tonnes. These must meet the SMT2 retrofit requirement by 1 July 2026. If you operate vans or lighter goods vehicles on international routes, this deadline is coming up fast.

DVSA Enforcement: Remote Detection Is Here

DVSA enforcement has stepped up considerably. Officers now use remote tachograph sensing technology that can detect potential hours-of-service infringements without pulling a vehicle over. That means a van or lorry could be flagged for follow-up before the driver even knows they've been noticed.

Fixed penalties start at £300 per infringement. Serious or repeated breaches can lead to vehicle immobilisation and, more worryingly for operators, a review of your operator licence. Licence loss or curtailment is a business-ending outcome for most hauliers.

The message here is simple: reactive compliance — where you deal with problems after they're flagged — is no longer enough. You need systems in place that catch issues before they become infringements. TruckCheck's hours monitoring and alert tools are built exactly for this kind of proactive oversight.

Core Domestic Limits: A Quick Refresher

Despite all the changes for international operations, the core domestic limits haven't changed. Here's a clean summary for drivers and managers to keep handy:

| Rule | Limit | |---|---| | Daily driving | 9 hours (extendable to 10 hours, twice a week) | | Weekly driving limit | 56 hours | | Fortnightly driving limit | 90 hours across any two consecutive weeks | | Break requirement | 45 minutes after 4.5 hours of driving | | Daily rest | 11 hours (reducible to 9 hours, up to three times a week) |

These limits apply to drivers operating under UK domestic rules. If you're unsure whether a particular journey triggers AETR requirements, it's worth getting clarification — the distinction matters for which rules apply and what records need to be kept.

Scotland Speed Limit Update

One more change worth noting: Transport Scotland has moved forward with aligning HGV speed limits with those in England and Wales. From early 2026, legislative steps have progressed to increase the HGV speed limit on single carriageways from 40mph to 50mph and on dual carriageways to 60mph. This reduces the frustrating speed differential between HGVs and other vehicles and should have some road safety benefits too — a sensible update that's been a long time coming.
