Tachograph Rules UK 2026: The Complete Driver's Guide
A UK HGV/PCV driver's complete tachograph guide — daily, weekly and break rules under EU 561/2006, Smart Tachograph 2 requirements from July 2026, and DVSA enforcement.
Quick answer: UK tachograph rules come from retained EU Regulation 561/2006 alongside the Road Transport (Working Time) Regulations 2005. Key limits: 9 hours daily driving (10h twice per week), 45-minute break after 4.5 hours of driving, 56 hours weekly driving cap, 90 hours across any two consecutive weeks, 11-hour daily rest (reducible to 9h up to 3× weekly), 45-hour weekly rest. Smart Tachograph 2 is required on most newly-registered HGVs/PCVs and on international journeys from July 2026. DVSA enforces with graduated fixed penalties (£50-£300+) and operator licence consequences.
What a tachograph actually is
A tachograph is an electronic device fitted to most UK HGVs and PCVs that records driver activity automatically:
- Driving time
- Other work time
- Periods of availability (POA)
- Rest time
- Distance driven, speed, location (Smart Tachograph)
The data is stored on the vehicle unit (VU) and on each driver's smart card. Operators must download both periodically and retain the records.
Which vehicles need a tachograph
- Goods vehicles over 3.5 tonnes gross vehicle weight (HGVs)
- Passenger vehicles carrying 9 or more passengers (including driver) — PCVs/buses/coaches
- Some smaller vans where trailer combination pushes total over 3.5t
Exemptions: emergency services, military, breakdown recovery (within 100km of base), some agricultural, non-commercial use.
The drivers' hours table
| Rule | Maximum | Notes |
|---|---|---|
| Daily driving | 9 hours | Extendable to 10h up to twice per week |
| Weekly driving | 56 hours | Calendar week (Mon-Sun) |
| Two-week driving | 90 hours | Any consecutive 2 weeks |
| Daily rest | 11 hours uninterrupted | Reducible to 9h up to 3× between weekly rests |
| Weekly rest | 45 hours uninterrupted | Reducible to 24h every other week (with compensation) |
| 4.5h break | 45 min full OR 15+30 split | After 4.5h accumulated driving |
The 4.5-hour break rule
The most-cited DVSA infringement. After 4.5 hours of accumulated driving, you must take:
- One unbroken 45-minute break, OR
- 15 minutes first + 30 minutes second (in that order — never 30+15)
The break can't include other work (loading, paperwork) — must be genuine rest.
Smart Tachograph generations
| Generation | Introduced | Key features |
|---|---|---|
| Analogue (paper chart) | Pre-2006 | Wax-coated paper charts, no electronics |
| Digital (Gen 1) | 2006 | Electronic recording, driver smart cards |
| Smart Tachograph (Gen 2) | June 2019 | GNSS position every 3 hours, secure communication |
| Smart Tachograph 2 | August 2023 | Enhanced anti-tampering, remote enforcement, ENC |
July 2026 — Smart Tachograph 2 retrofit
Under the EU Mobility Package (retained in UK law), all HGVs and PCVs engaged in international transport must be fitted with Smart Tachograph 2 by July 2026. This includes:
- Vehicles registered between June 2019 and August 2023 (Gen 2 → Gen 2 v2)
- Older digital tachograph vehicles (Gen 1) used internationally
UK-only operations have additional time but are advised to retrofit ahead of the deadline.

FAQs
What's the difference between drivers' hours and the Working Time Directive?
Drivers' hours (EU 561/2006) covers driving time, breaks, and rest. WTD (RTD 2005) covers total working time including loading, paperwork, training. Both apply simultaneously.
Can I use my driver card in another country's tachograph?
UK driver cards work in any EU/EEA Smart Tachograph. The card identifies you uniquely; the tachograph records under that ID regardless of country.
What if I forget my driver card?
Make a manual printout at the start of the shift showing your name and licence number. Retain it. Repeated forgetting is itself a flag for DVSA.
Can I drive past 4.5 hours if I'm "nearly home"?
No — the rule is absolute. Driving past 4.5 hours without the break is a fixed-penalty offence. Plan stops accordingly.
