If you drive an HGV professionally in the UK, understanding tachograph rules is not optional — it is a legal requirement. Tachographs record your driving time, rest periods, and speed, and failing to comply can result in fines, prosecution, and loss of your licence. This guide covers everything HGV drivers need to know about tachograph rules in 2026.
What Is a Tachograph?
A tachograph is a recording device fitted to commercial vehicles that logs driving time, rest periods, speed, and distance. It creates an auditable record that enforcement authorities (DVSA, police) can inspect at the roadside or at your operator's premises.
There are two types of tachograph:
- Analogue tachograph: Uses a paper disc (chart) that records data mechanically. These are found in older vehicles and are being phased out.
- Digital tachograph: Records data electronically on a smart card. Required in all vehicles first registered after 1 May 2006. Smart tachographs (Generation 2) are required in new vehicles registered after June 2019 and include remote DSRC communication.
Which Vehicles Need a Tachograph?
Tachographs are required in vehicles used for the carriage of goods where the maximum permissible weight (including any trailer) exceeds 3.5 tonnes, and in passenger-carrying vehicles with more than 9 seats (including the driver) used for hire or reward. Certain exemptions apply — for example, vehicles used by the armed forces, police, and fire services, and vehicles used for non-commercial carriage of goods within a 100 km radius under specific conditions.
EU and GB Drivers' Hours Rules
Most HGV drivers operating in the UK and EU are subject to EU Drivers' Hours rules (EC Regulation 561/2006), which set the following limits:
| Rule | Limit |
|---|---|
| Daily driving limit | 9 hours (extendable to 10 hours twice per week) |
| Weekly driving limit | 56 hours |
| Fortnightly driving limit | 90 hours |
| Continuous driving before break | 4.5 hours |
| Break duration | 45 minutes (or 15 + 30 minutes in that order) |
| Daily rest (regular) | 11 consecutive hours |
| Daily rest (reduced) | 9 consecutive hours (max 3 times per week) |
| Weekly rest (regular) | 45 consecutive hours |
| Weekly rest (reduced) | 24 consecutive hours (must be compensated) |
GB domestic drivers' hours rules apply to vehicles not covered by EU rules — for example, certain agricultural, emergency, and local goods vehicles. These rules are different and less restrictive in some areas.
How to Use a Digital Tachograph
Before driving, insert your driver smart card into the tachograph and enter your country of work. The tachograph will automatically record your driving time. When you are not driving, manually select the correct activity mode:
- Driving (steering wheel symbol): Automatically recorded when the vehicle is moving.
- Other work (hammer symbol): For loading, unloading, vehicle checks, and other work duties.
- Availability (wide horizontal bar): For waiting time, ferry crossings, and time when you are available but not working.
- Rest (bed symbol): For breaks and daily/weekly rest periods.
Manual Entries and Out-of-Scope Driving
If you have driven a vehicle not fitted with a tachograph (for example, a car or a vehicle exempt from tachograph rules), you must make a manual entry on your smart card or analogue chart to account for that time. Failure to account for all time is a tachograph offence.
Tachograph Infringements and Penalties
DVSA and police officers can inspect tachograph records at the roadside. Infringements are categorised by severity:
- Minor infringement: Warning issued, no immediate penalty.
- Serious infringement: Fixed penalty notice (typically £300) or prohibition from driving.
- Most serious infringement: Court prosecution, unlimited fine, potential disqualification.
Operators can also be prosecuted for tachograph offences committed by their drivers, particularly if they knew about or encouraged non-compliance.
Downloading and Analysing Tachograph Data
Digital tachograph data must be downloaded regularly — at least every 90 days from the vehicle unit and every 28 days from driver smart cards. Operators must analyse the data for infringements and keep records for at least 12 months. Failure to download or analyse data is an operator compliance offence.
