UK Driver Hours & Tachograph Rules 2025: What Operators Must Do Now

If you run a haulage operation in the UK, you'll already know that keeping on top of driver hours and tachograph rules is non-negotiable. But 2025 has brought a fresh wave of changes that every operator, transport manager, and driver needs to understand — and act on quickly. With new record-keeping requirements, looming tachograph retrofit deadlines, and DVSA enforcement as active as ever, now is not the time to be caught out.

Here's what's changed, what it means for your operation, and what you need to do about it.

What's Changed in April 2025

On 21 April 2025, updated regulations came into force reflecting the UK's post-Brexit legal position. Official guidance has been revised to replace references to "EU law" with "assimilated law" — a terminology shift that matters because it signals these are now firmly UK domestic rules, not EU ones.

The DVSA has also used this update to tighten up several grey areas, including:

• A formal definition of "goods" for the purposes of drivers' hours rules
• Clarification on national derogations for radio and television broadcasting vehicles
• Updated lists of countries and which regulations apply to journeys through them

None of this fundamentally rewrites the rulebook overnight, but it does mean your internal policies, training materials, and compliance documentation should be reviewed and updated to reflect current language and definitions.

Record Keeping: The 28-Day vs 56-Day Rule

This is the change most likely to catch operators off guard, particularly those running international work.

Domestic journeys (within Great Britain)

For drivers operating solely within Great Britain, the record-keeping requirement remains at 28 days under assimilated drivers' hours regulations. Drivers should be able to produce their records for the current day plus the previous 28 days at any roadside check.

International journeys to EU Member States

If your drivers are crossing into EU countries, the rules are different. From April 2025, drivers must be able to produce 56 days of records — that's the current day plus the previous 56 days. This aligns with what EU member states require at their own roadside checks, and failing to carry sufficient records could result in penalties on both sides of the Channel.

Journeys through non-EU countries

For routes that pass through or to non-EU countries (think Turkey, Russia, or other nations), AETR rules apply. Make sure your drivers doing these runs understand which ruleset governs their journey.

If you're using compliance software like Fleet77 to manage tachograph data and driver records, now is a good time to check your data retention settings align with these requirements — particularly if you have drivers doing international work.

Tachograph Retrofit Deadlines You Cannot Afford to Miss

This is the most time-sensitive issue facing operators right now. There are two hard deadlines you need to have in your diary.

18 August 2025 — Smart Tachograph 2 for international vehicles

If you have vehicles fitted with a Smart Tachograph 1 (also known as Gen 2 tachographs) that are used for international journeys, they must be retrofitted with a Smart Tachograph 2 by 18 August 2025.

That deadline is closer than it looks. Workshop slots for tachograph calibration and fitting are already under pressure across the industry, so if you haven't already booked your vehicles in, do it now. Don't leave it until July and find your preferred tachograph centre is booked solid.

1 July 2026 — Lighter vehicles used for international transport

Vehicles with a gross vehicle weight between 2.5 and 3.5 tonnes used for international transport will need to comply by 1 July 2026. This affects operators running lighter vans on cross-border work — a sector that's increasingly under scrutiny.

Start planning for this now rather than scrambling in 12 months' time.

Enforcement: The DVSA Isn't Letting Up

The DVSA continues to take a robust approach to enforcement, and the penalties for getting this wrong are significant:

• Fixed penalties of up to £300
• Graduated deposits of up to £1,500 at the roadside
• Court summons for more serious or repeated offences

Beyond roadside checks, operators should also be aware that tachograph analysis and drivers' hours compliance form a core part of the DVSA Earned Recognition audit standards for HGV operators. The DVSA Earned Recognition audit standards set out clear expectations for how operators should monitor and manage driver hours data — including regular analysis of tachograph records and documented processes for dealing with infringements.

If you're working towards or maintaining Earned Recognition status, these 2025 changes make it even more important that your compliance processes are watertight and up to date.

What Operators Should Do Right Now

To stay on the right side of the law, here's a practical checklist:

1. Review and update your internal policies to reflect the new assimilated law terminology and updated definitions
2. Check which record-keeping requirement applies to each of your drivers — 28 days for domestic, 56 days for EU international runs
3. Audit your fleet to identify any vehicles fitted with Smart Tachograph 1 units doing international work — and book them in for retrofit before August
4. Brief your drivers on the changes, particularly those doing international or cross-border work
5. Check your tachograph analysis process is catching infringements promptly and that records are being retained for the correct periods
6. Consult the latest GOV.UK guidance at gov.uk/drivers-hours to make sure you're working from current information

Tools like Fleet77 can help you keep track of tachograph data, flag potential infringements, and maintain the kind of audit trail that the DVSA expects to see — but whatever systems you use, the fundamentals still come down to consistent processes and well-informed drivers.

Staying compliant in 2025 means staying informed, acting early on the retrofit deadlines, and making sure your record-keeping holds up whether your drivers are running domestic routes or heading to the continent.
