Tachograph in the UK – rules, exemptions and DVSA enforcement [2026]

A tachograph is a device that records a driver's driving time, rest periods and working hours — mandatory for vehicles over 3.5 tonnes GVW used in commercial road transport. Following Brexit, the UK retained rules largely based on EU Regulation 165/2014, but certain domestic differences were introduced that are crucial for operators running both domestic (GB domestic) and international UK–EU services. Ignorance of the rules can cost a driver or operator several thousand pounds in fines, or even the loss of an operator's licence. This guide covers: when a tachograph is mandatory in the UK, what exemptions apply, how Smart Tachographs differ from analogue ones, how a DVSA check works, what penalties apply for infringements, and how the rules apply to EU drivers transiting through the UK.

When is a tachograph mandatory in the UK?

The basic rule: a tachograph is required in vehicles with a gross vehicle weight (GVW) exceeding 3.5 tonnes used in commercial road transport. This covers:

• HGVs (Heavy Goods Vehicles) >3.5t GVW
• Vehicle combinations (tractor unit + trailer) >3.5t GVW
• Passenger-carrying vehicles (>9 seats including the driver) used commercially

Domestic vs international transport

Type of transport	Applicable rules
Domestic (GB domestic)	GB domestic tacho rules + optional exemptions
International (UK–EU, UK–other countries)	EU Regulation 165/2014 (retained in UK law)
Cabotage in the UK by an EU carrier	EU tacho rules applied in the UK

Exemptions – when is a tachograph not required?

This is a critical and often misunderstood area. UK law provides a number of exemptions from the tachograph requirement:

Exemption 1: Vehicles <7.5t GVW on routes <100 km (GB domestic rule)

In domestic (Great Britain domestic) operations, vehicles up to 7.5 tonnes GVW do not need to use a tachograph, provided: - The route does not exceed 100 km from base (not 100 km from the driver's home) - The operation is carried out as own-account transport, not commercial transport for a customer

Note: This exemption applies only to GB domestic operations. If the same vehicle travels to the EU, the exemption does not apply.

Exemption 2: Rural exemption

Vehicles used for transport in agriculture, horticulture, forestry, animal husbandry or fishing may be exempt from the tachograph requirement within 100 km of base. This covers: - Agricultural tractors - Vehicles collecting milk from farms - Vehicles delivering animal feed, fertilisers and seeds

Exemption 3: Military, police and emergency service vehicles

All vehicles belonging to UK armed forces, police, fire service and ambulance services are exempt.

Exemption 4: Specialist construction and service vehicles

Vehicles used exclusively on a construction site or within an enclosed area (e.g. a port or airport) may not require a tachograph. It is advisable to consult DVSA on individual cases.

Exemption 5: Historic vehicles (pre-1947)

Vehicles registered before 1 January 1947 are exempt from the tachograph requirement.

Exemptions summary table

Exemption	Condition	Transport type
<7.5t GVW + <100 km from base	GB domestic own-account	Domestic
Rural exemption	Agriculture, forestry, fishing	Domestic
Military/police/emergency services	Uniformed services	Domestic and international
Own light transport	<3.5t GVW	Any
Historic vehicle	Pre-1947	Any

Smart Tachograph – new requirements from 2025

From 21 August 2025, all new vehicles over 3.5t GVW registered in the UK and EU must be fitted with a Smart Tachograph Generation 2 (Smart 2). These devices differ from earlier generations:

Tachograph generations

Generation	Features	Installation requirement
Analogue	Paper disc (chart)	Vehicles manufactured before 1998
Digital (1st gen)	Driver card, electronic data	2003–2019
Smart Gen 1	GPS, DSRC (roadside communication)	2019–2024
Smart Gen 2	GPS, DSRC, ITS, V2I interface	From 21.08.2025 (new vehicles)

What is new in Smart Tachograph Gen 2?

• Automatic GPS location recording every 3 hours and at every border crossing
• Remote communication with DVSA (DSRC – Dedicated Short Range Communication) – an officer can read tachograph data without stopping the vehicle (read-from-the-road)
• ITS interface – integration with fleet management systems
• Automatic border-crossing detection – facilitates compliance monitoring for international transport

Driving and rest time rules in the UK

For international transport (UK–EU and other routes) the rules are identical to EU Regulation 561/2006:

Parameter	Limit
Daily driving time	Max 9h (up to 10h a maximum of twice per week)
Weekly driving time	Max 56h
Driving time over 2 weeks	Max 90h
Daily rest	Min 11h (reducible to 9h a maximum of 3 times per week)
Weekly rest	Min 45h (reducible to 24h once every 2 weeks)
Break after 4.5h driving	Min 45 min (or 15+30 min)

GB domestic rules – differences

For domestic (GB domestic) transport, the UK applies slightly different rules – the "GB domestic drivers' hours rules": - Daily driving limit: 10 hours (not 9h as under EU rules) - Break rule: 30-minute break after 5.5h driving (not 45 min after 4.5h) - Daily rest: minimum 10h (not 11h as under EU rules)

GB domestic rules apply when the vehicle has not left the UK during that week and does not plan to do so.

DVSA enforcement – how does it work?

DVSA (Driver and Vehicle Standards Agency) carries out two types of check:

Roadside check

DVSA officers stop HGVs at designated check points or at random. They examine: - The driver card inserted in the tachograph - A tachograph printout (or analogue charts for the previous 28 days) - Driving and rest times for the current day and preceding days - Validity of the driver card (expired card = serious infringement)

Remote check (read-from-the-road)

Smart Tachograph Gen 1 and Gen 2 allows DVSA to read data without stopping the vehicle – using a roadside DSRC device. If the system detects irregularities, the vehicle may be directed to pull over for a detailed inspection.

Infocam and data analysis

DVSA uses the Infocam system to target high-risk vehicles. Data from checks, infringement history and operator information are analysed, and vehicles with a high-risk profile are stopped more frequently.

Penalties for tachograph infringements

Infringements are classified by severity:

Infringement category	Examples	Penalty
Minor	Missing chart disc for 1 day	Verbal advice
Serious	Driving time exceeded by >1h	Fixed Penalty £300
Most serious	Tachograph tampering, fraud	Prosecution, fine up to £5,000
Operator offence	Systematic fleet infringements	Suspension/revocation of operator's licence

Immobilisation

In the case of serious infringements, DVSA has the power to immobilise the vehicle on the spot until the driver has rested or the infringement has been remedied. This applies where the driver is severely fatigued and continued driving would pose a safety risk.

EU drivers transiting through the UK – which rules apply?

This question concerns Polish, Czech and other European carriers operating through the UK:

• EU-registered vehicles carrying out transport through the UK apply EU Regulation 561/2006 and 165/2014 – the same rules as in the EU
• UK law retains these regulations as "retained EU law" for international transport
• Drivers must observe the same time limits and carry a driver card
• DVSA has full authority to stop and inspect EU vehicles on UK territory
• Penalties imposed by DVSA are enforceable in the UK; a driver may be required to pay a fixed penalty before leaving the UK
