UK Driver Hours Rules 2025: What Every Haulier Must Know Now

If you run HGVs on international routes, 2025 brought a stack of regulatory changes that you genuinely cannot afford to ignore. From a shift in the legal framework governing driver hours to new tachograph hardware deadlines and doubled record-keeping requirements, there's a lot to get your head around. Whether you're a transport manager juggling compliance across a fleet, or a driver who wants to stay on the right side of the DVSA at the roadside, here's a clear breakdown of what changed, when it changed, and what it means for your day-to-day operations.

The Big Shift: AETR Rules Now Apply to International Journeys

The most fundamental change came into effect on 21 April 2025. Before this date, UK rules for international HGV and PSV operations were based on "assimilated" EU regulations carried over after Brexit. From April 2025, those were replaced by the AETR (European Agreement Concerning the Work of Crews of Vehicles Engaged in International Road Transport) framework for any journey involving the UK and a non-EU country.

This matters because, while AETR rules look similar to EU rules on the surface, there are some key operational differences worth knowing:

• Reduced weekly rest: Under AETR, a driver is only permitted one reduced weekly rest period between two full weekly rests — compared to the slightly more flexible approach that applied previously.
• Home base rules: AETR does allow drivers to work for more than four consecutive weeks without returning to their home base, which can be relevant for longer international tours — but this flexibility comes with stricter rest conditions attached.

If your drivers cross international borders — into Europe, through the Channel Tunnel, or beyond — these are the rules that now apply to them. Domestic-only operations are unaffected (more on that below), but mixed fleets need to be very clear about which ruleset applies on which job.

The 56-Day Rule: Your New Record-Keeping Requirement

Also from April 2025, DVSA roadside inspections for international HGV drivers now require 56 days of tachograph records — that's the current day plus the previous 56 days. This doubled the previous 28-day requirement overnight.

What counts toward those 56 days? Everything:

• Digital tachograph data downloaded from the vehicle unit
• Analogue charts (where applicable)
• Manual entries for any period not automatically recorded — including rest days, annual leave, sick days, and any other work

That last point catches people out. If a driver took a week's holiday in the middle of those 56 days, there needs to be a manual entry on record to account for that time. Gaps in the data aren't just untidy — they're a compliance failure at the roadside.

The DVSA has ramped up enforcement checks specifically to monitor this transition, and the penalties for failing to produce the full 56 days are serious: significant fines and potential vehicle prohibitions. This is exactly the kind of requirement that benefits from a digital system — tools like TruckCheck are designed to keep tachograph data, manual entries, and driver records in one place so nothing slips through the cracks when a DVSA officer pulls a vehicle over.

Smart Tachograph 2: The Hardware Deadline You Need to Check

By 19 August 2025, all vehicles undertaking international journeys that were previously fitted with Smart Tachograph Version 1 were required to be retrofitted with Smart Tachograph Version 2 (or an approved transitional version).

Why does it matter?

Smart Tachograph 2 introduces improved automated recording of border crossings — a key requirement for international compliance — along with more robust anti-tampering features that give DVSA enforcement teams better visibility of data integrity. Put simply, if your vehicle is crossing borders without the right hardware fitted, you're already in breach.

What to check right now

• Review your fleet records and confirm which tachograph version is fitted to each vehicle on international duties
• If any vehicle was missed in the retrofit window, get it booked in immediately
• Ensure your tachograph calibration records are up to date — this is a standard audit point under the DVSA Earned Recognition audit standards, which expect operators to maintain accurate records of tachograph inspections and calibrations

Domestic Operations: What Hasn't Changed (Yet)

If your fleet operates exclusively within the UK, the April 2025 changes don't directly apply to you. Drivers on domestic-only routes continue to follow existing UK domestic driving hours rules or the assimilated EU rules, depending on the vehicle and operation type.

However, there's a significant change coming that lighter commercial vehicle operators should already be planning for.

The Van Tacho Rules: July 2026

From 1 July 2026, newly registered goods vehicles weighing between 2.5 and 3.5 tonnes used for international hire and reward journeys must be fitted with Smart Tachograph 2 and comply with international driver hours rules. This is often referred to as the "van tacho" rollout, and it's a significant expansion of who tachograph rules apply to.

If you run vans or light goods vehicles on any cross-border commercial work, now is the time to audit your fleet and understand whether these rules will apply to you — not when the deadline is a fortnight away.

What Good Compliance Looks Like in Practice

The DVSA updated its Goods Vehicles: Drivers' Hours and Tachographs guidance manual in late 2025, including a stricter definition of "goods" to ensure commercial activities aren't being used to sidestep the rules. Operators who take compliance seriously — and particularly those working toward or maintaining DVSA Earned Recognition status — should review their internal procedures against the updated guidance.

At a practical level, good compliance in 2025 and beyond means:

• Regular tachograph data downloads — at least every 28 days from the vehicle, every 28 days from driver cards
• Complete records covering all 56 days, including manual entries for non-driving time
• Hardware audits to confirm Smart Tachograph 2 is fitted to all applicable vehicles
• Driver briefings on the AETR rule changes, especially around reduced weekly rest limits
• A reliable system for storing and retrieving records quickly — because a roadside inspection doesn't come with much notice

Fleet compliance software like TruckCheck can help transport managers stay on top of these requirements without relying on spreadsheets and paper trails that are easy to lose and hard to audit.

The rules around driver hours and tachographs exist for good reason — road safety depends on drivers being properly rested and operators being accountable. The 2025 changes raise the bar, but they're manageable if you stay organised and proactive.
