UK Driver Hours Rules 2025: What Every Transport Manager Must Know

If you're a transport manager or haulier in the UK, 2025 is not the year to take your eye off the compliance ball. A meaningful set of regulatory changes came into force on 21 April 2025 under The Drivers' Hours and Tachographs (Amendment and Modification) Regulations 2025, and they carry real consequences for anyone running vehicles on international routes. On top of that, there are hardware deadlines looming and a DVSA enforcement approach that's become noticeably sharper. Whether you run a single truck or a large mixed fleet, here's what you need to know right now.

The 56-Day Record Rule: The Biggest Change for International Operators

This is the one that's catching people out, so let's get straight to it.

If your drivers cross into the EU or travel through any AETR signatory countries, they must now be able to produce tachograph records and manual entries for the current day plus the previous 55 calendar days — that's 56 days in total. Before April 2025, the requirement was 28 days. It's doubled overnight.

At a roadside check, an enforcement officer can request those records on the spot. If your driver can't produce them — whether due to missing data cards, incomplete manual entries, or gaps from a previous operator — that's a prosecutable offence. The burden sits on the driver during the check, but the responsibility to maintain proper records ultimately sits with you as the operator.

What this means in practice

• Drivers must carry their digital tachograph card with sufficient data stored, plus any printed or manual records to fill any gaps
• Your back-office systems need to be pulling and archiving tachograph data consistently across a rolling 56-day window
• If a driver has recently joined from another company, make sure you have their previous records before they go anywhere near an international route

This is exactly the kind of thing that fleet compliance software like TruckCheck is built to help you track — keeping a clean, accessible archive of driver data so nothing falls through the cracks at the roadside.

AETR Rules Are Now Formal: Goodbye to Certain Flexibilities

For international journeys involving non-EU countries (think Turkey, Russia, or other AETR members), the UK has now formally shifted to the AETR framework. This sounds technical, but there's a practical consequence worth flagging.

Under the old EU rules, there was a degree of flexibility around "unforeseen events" — a driver could, in exceptional circumstances, extend driving time to reach a safe place for weekly rest. That particular allowance is now gone for AETR journeys. The rules are stricter, and they're applied more rigidly.

At the same time, the UK has officially rebranded what used to be called "retained EU law" as "assimilated drivers' hours rules." The core driving limits haven't changed, but all DVSA guidance now uses this terminology. Update your internal documentation, training materials, and driver briefings accordingly — using outdated language during an audit doesn't inspire confidence.

Core Hours Rules: A Refresher (Domestic Operations)

For domestic-only operations — trucks that never cross the border — it's broadly business as usual. But it's worth making sure every driver on your fleet knows these limits cold, especially newer recruits.

| Rule | Limit | |---|---| | Daily driving | 9 hours (extendable to 10 hours, twice a week) | | Weekly driving limit | 56 hours maximum | | Fortnightly limit | 90 hours across any two consecutive weeks | | Break requirement | 45 minutes after 4.5 hours (can be split: 15 min then 30 min) | | Daily rest | 11 hours (reducible to 9 hours, up to three times between weekly rests) |

These aren't suggestions — they're legal requirements, and the DVSA's Earned Recognition audit standards make clear that operators are expected to have robust systems in place to monitor compliance against all of these thresholds. If you're working towards Earned Recognition or already hold it, your processes around hours monitoring will be scrutinised closely.

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

Alongside the regulatory changes, there's a hard equipment deadline that international operators need to action immediately if they haven't already.

By 18 August 2025, any vehicle used on international journeys that is currently fitted with a Smart Tachograph Version 1 (SMT1) must be retrofitted with a Smart Tachograph Version 2 (SMT2). This isn't optional, and there's no grace period being signalled.

SMT2 units offer enhanced remote communication capabilities, which feeds directly into the DVSA's current enforcement strategy. The agency has made no secret of its move towards remote tachograph monitoring — meaning officers can flag potential infringements before a vehicle even pulls into a check site. Pair that with more frequent roadside spot checks under their stated "fatigue-first" enforcement approach, and the message is clear: non-compliant hardware will be found.

What's coming next

Looking further ahead, from 1 July 2026, the SMT2 requirement will extend to light goods vehicles between 2.5 and 3.5 tonnes used in international hire and reward transport. If you run any vans in that weight class on cross-border work, start planning now.

A Quick Note on Scottish Speed Limits

One regional change worth flagging for operators running routes through Scotland: HGV speed limits on single carriageways in Scotland are expected to rise from 40mph to 50mph, bringing them in line with England and Wales. This should reduce the risk of "convoying" — where HGVs bunch up trying to overtake each other — and make journey time planning more straightforward. Update any route guides or driver briefings that reference Scottish speed limits.

Staying on Top of It All

The honest truth is that compliance in 2025 requires more active management than it did even two years ago. The 56-day record requirement, the SMT2 retrofit deadline, tighter AETR rules, and a more digitally-enabled DVSA enforcement approach all add up to a higher bar for operators.

Using a platform like TruckCheck to centralise your driver records, tachograph data, and compliance checks means you're not relying on spreadsheets and memory when an audit or roadside check happens. Good systems make good compliance — and that protects your operators licence, your drivers, and the public.
