UK Driver Hours in 2025: What Every Transport Manager Must Know Now

If you're a transport manager or fleet operator in the UK, 2025 has already thrown a fair bit at you. New regulations, tightening technology requirements, and an ageing driver workforce mean the compliance landscape is shifting faster than it has in years. Whether you're running domestic trunking routes or cross-border international hauls, there are changes you need to act on — some with deadlines that are already close. Here's a clear breakdown of what's changed, what's coming, and what you need to do about it.

The AETR Shift: What It Means for International Operators

The biggest regulatory change of 2025 came into force on 21 April, through the Drivers' Hours and Tachographs (Amendment and Modification) Regulations 2025. The headline change? The formal adoption of AETR rules for international journeys.

AETR — the European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport — now applies to UK journeys travelling to non-EU AETR signatory countries, or those transiting the EU to reach them. These rules replace the old "retained EU" legislation that had been carried over post-Brexit.

In practical terms, the driving limits under AETR are broadly similar to what most operators are used to. But the administrative requirements have changed significantly, and that's where many fleets will trip up.

The 56-Day Record Rule

This one catches people out. As of late 2024 and reinforced by the April 2025 regulations, drivers on international routes must now be able to produce 56 days' worth of tachograph records at the roadside — that's the current day plus the previous 55. This doubles the old 28-day requirement.

Those records must cover digital data, analogue charts, and any manual entries. At a roadside check, enforcement officers can and will ask for all of it. Failing to produce the full set can result in fines of up to £300 per infringement — and if multiple drivers are non-compliant at once, that adds up fast.

Make sure your drivers know what they need to carry and that your back-office systems can pull 56 days of data quickly when required. Tools like TruckCheck can help you keep records centralised and accessible, rather than relying on drivers to carry everything manually.

Smart Tachograph 2: Act Before August

The DVSA has been pushing hard on the transition to Smart Tachograph 2 (SMT2), and 2025 brings two firm deadlines that operators cannot afford to ignore.

The August 2025 Retrofit Deadline

Any vehicle currently fitted with a Smart Tachograph 1 unit must be retrofitted with SMT2 by 18 August 2025 if it is going to continue operating on international routes. That date is closer than it might feel, especially when you factor in workshop availability and the time it takes to book in retrofits across a fleet.

SMT2 units bring meaningful improvements — automatic border crossing recording, more precise GPS tracking, and significantly better anti-tampering features. They reduce the manual logging burden on drivers, which is genuinely useful. But the transition has to be managed properly, and leaving it to July is a risk.

Light Commercials: A 2026 Deadline to Plan For Now

If your operation includes lighter vehicles — specifically those with a GVW between 2.5 and 3.5 tonnes — these must be fitted with SMT2 by 1 July 2026. That feels a long way off, but given fleet sizes and the current demand on tachograph installers, planning ahead makes sense.

Domestic Hours: Stable, But Worth Revisiting

While international rules have shifted, UK domestic driving hours remain largely unchanged. That said, it's worth a quick refresher — especially if you have drivers who've recently moved from international to domestic routes, or if you're onboarding new or returning drivers.

• Daily driving limit: 9 hours, extendable to 10 hours on up to two days per week
• Break requirement: A 45-minute break after no more than 4.5 hours of driving (this can be split into a 15-minute break followed by a 30-minute break)
• Daily rest: A minimum of 11 hours, with some flexibility for reduced rest periods

These rules are well-established, but enforcement remains active. The DVSA's Earned Recognition audit standards set out exactly what a compliant operator looks like from a record-keeping and monitoring perspective — and they're a useful benchmark even if you're not enrolled in the scheme.

The New CPC "Return to Driving" Route

One genuinely positive development in 2025 is the introduction of a new 35-hour "Return to Driving" CPC course, which launched in February 2025. This is aimed squarely at the driver shortage problem — allowing drivers whose Driver CPC has lapsed for more than two years to regain their qualification for UK-only driving without having to sit the full initial qualification tests again.

Given that the average UK HGV driver is now 51 years old, and around 55% of the workforce is aged between 50 and 65, the industry is facing a significant generational handover problem. A persistent shortfall of approximately 60,000 to 70,000 drivers remains despite some easing of the acute crisis seen in 2021. This new CPC route won't solve everything, but it's a practical way to bring experienced drivers back into the fold.

London Operators: Don't Overlook the DVS Changes

If any of your vehicles operate in Greater London, the Direct Vision Standard (DVS) has tightened again. From 2025, HGVs over 12 tonnes must now hold a minimum three-star rating or be equipped with a "Progressive Safe System" to legally operate within Greater London.

This is an area where non-compliance carries real operational consequences — vehicles can be turned away or fined. If you haven't checked your fleet's DVS rating recently, now is the time.

Your Compliance Checklist for 2025

To bring it all together, here's what needs to be on your radar right now:

• Book SMT2 retrofits for any Smart Tachograph 1 vehicles before 18 August 2025
• Brief your international drivers on the 56-day record requirement
• Check your data systems can produce 56 days of tachograph records quickly and cleanly
• Review DVS ratings for any vehicles operating in Greater London
• Look into the new CPC Return to Driving route if you have former drivers you could bring back
• Cross-reference your operation against the DVSA Earned Recognition standards as a compliance health check

Staying on top of this doesn't have to be complicated, but it does take organisation. Having a centralised system — whether that's TruckCheck or something else — that keeps your records, driver data, and compliance checks in one place makes all of this significantly more manageable.
