What is the new legislation regarding Tachographs in the UK?

The new tachograph legislation states that vehicles over 2.5 tonnes undertaking international journeys for hire and reward are required to have a Smart tachograph 2.

Legislation has been rolled out gradually:

- Existing vehicles in international transport had a 2025 deadline, while vehicles over 2.5 tonnes in international transport for hire and reward have until 1 July 2026.

Who do the new tachograph rules apply to, and who do they not apply to?

As part of the new EU mobility package, the tacho laws for HGVs apply to:

• Vehicles for the transport of goods with a maximum allowable mass of over 3.5 tonnes.

• Vehicles for the transport of persons that are designed or permanently adapted to transport more than 9 people, including the driver.

This means a wide range of people and businesses are impacted, including:

• Hauliers operating across the UK, Ireland and Europe

• HGV drivers and transport operators

• Fleet managers responsible for compliance

• Transport managers

• SME transport companies using vans, LCVs and HGVs

• Freight forwarders that arrange international travel

• Logistics managers who plan cross-border transport

• Transport planners

What vehicles need a tachograph?

What is a tachograph, and how does a tachograph work?

A tachograph is a device installed in HGVs that records driving time, speed, breaks and rest periods. It uses a personalised smart card or driver card, which is inserted at the start of a shift and logs all this information.

A tachograph is used to ensure compliance with the set of EU rules which prevent driver fatigue, create good working conditions, road safety and fair competition for those transporting goods or passengers by road.

How to use a Smart 2 tachograph

To use a Smart 2 tachograph:

1. Insert your driver card

2. Complete manual entries

3. When you start driving, the mode will automatically switch to Drive

What are the key differences between first and second-generation Smart tachographs?

You might already have the Smart Tacho 1 or might just be curious. But what exactly are the differences? What are the key features of a Smart tachograph 2 system?

The new digital tachograph rules modernise and improve compliance and control within the transport sector. The Smart Tacho 2 is an advanced tachograph that accurately registers driving and rest times, border crossings and loading/unloading activities.

The main differences of the second generation smart tachographs are:

1. Automatic recording of border crossings
2. Logging of loading and unloading activities along with vehicle positioning
3. Improved compliance and transparency with remote enforcement capabilities, which means fully compliant drivers don’t need to be stopped by authorities
4. Efficiency with double the storage capacity to 56 days instead of 28
5. Enhanced security via the Global Navigation Satellite System (GNSS) as it verifies the GPS location, which makes it anti-tamper proof.
6. Real-time display of the vehicle's current country
7. Additional motion sensors
8. Expanded Dedicated Short-Range Communication (DSRC) data, including maximum driving time, facilitating remote monitoring by enforcement authorities.

Full vs transitional Smart Tachograph 2: what is the difference?

There are two versions of the Smart Tachograph 2: full and transitional. Both support the recording of drivers' activities and other functions required by the legislation.

However, the transitional version does not include the Galileo location verification functionality available in the full version. Since 24 December 2025, newly registered goods vehicles within scope must be equipped with a full Smart Tachograph 2.

Vehicles registered before that date with a permitted transitional Smart Tachograph 2 do not automatically need another retrofit. Operators should verify which version is fitted and whether it is suitable for their international transport activities.

What are the benefits of upgrading to a Smart tachograph 2 for your transport business?

The new legislation requires hauliers to upgrade vehicles and train their staff. It could also mean increased admin for SMEs, more data to download and manage, and a need for stronger compliance processes. You should also ensure any negative impact on delivery times is kept at a minimum to ensure customer satisfaction while this transition takes place.

This requires investment, but the improved tracking and compliance are to help transport companies become more efficient. Accurate registration prevents fines, and the advanced functions optimise routes and maintenance. It is important to keep up with innovations such as the smart tachograph, but why do so many hauliers invest in the Smart Tacho 2? It’s not just because it is (or will be) required by law. It also comes with numerous other advantages.

Automatic border registration and accurate journey registration

Automatic border registration is one of the major advantages of the smart tachograph. This means that drivers no longer have to manually record border crossings, which saves time and reduces the chance of errors. The smart tachograph also registers journeys more accurately than ever before. This ensures that all driving and rest times are correctly recorded, which helps with legislation compliance. Fewer errors means less chance of violations and fines.

Improved compliance, efficiency and transparency

Thanks to its accurate registration and automatic functions, the smart tachograph helps hauliers with improved compliance. This helps prevent violations and the associated fines, which ultimately saves costs. A smart tachograph also contributes to more efficient business operations. The advanced functions help with optimising routes and scheduling maintenance, which means less downtime and better use of resources. In addition to all that, smart tachographs provide more transparency in operations. Enforcement authorities can carry out checks faster and more efficiently, which contributes to a more level playing field for all hauliers.

What is the Smart tachograph Version 2 requirements and Smart tachograph 2 deadline?

Since August 2023, all new transport vehicles must be equipped with the Smart Tacho 2:

• From 21 August 2023: All newly registered in-scope vehicles (goods vehicles over 3.5 tonnes and passenger vehicles with 10 or more seats) undertaking international journeys must be equipped with a 'full' or 'transitional' SMT2.
• From 21 February 2024: All newly registered in-scope vehicles, regardless of journey type, must have an SMT2 installed.
• Since 31 December 2024: Existing in-scope vehicles with analogue or digital tachographs used for international journeys were required to retrofit an SMT2.
• From 19 August 2025: Vehicles equipped with Smart Tachograph 1 used for international journeys were required to upgrade to SMT2.
• By 1 July 2026: All goods vehicles over 2.5 tonnes undertaking international journeys for hire and reward must be fitted with an SMT2.

To ensure you comply with the 1 July 2026 deadline, companies must upgrade their fleet in time and staff must be trained to become familiar with the new technology of the Smart Tacho 2.

How to avoid penalties and disruption regarding the new tachograph law

The Driving Standards Agency (DVSA) is tasked with enforcement in the UK. While the penalty for not adhering to the new rules varies depending on the country, in the UK, it is £300 (€350) for driving without an appropriate tachograph. For repeat violations, it can also result in vehicle immobilisation, unlimited court fines of up to £5,000 and suspension of operating licences.

Penalties for not having the appropriate tachograph aren’t the only issue. If you do not plan to be compliant when it becomes mandatory, you could face disruption to your business. This, in turn, could impact your customer satisfaction and reputation.

What do the UK tachograph requirements mean for HGV drivers' hours rules?

Tachograph driving hours regulations limit the amount of driving and working time that can be carried out by most HGV drivers for journeys between the EU and UK or fully inside the EU or UK. If the maximum weight of your vehicle or vehicle combination is more than 3.5 tonnes, then these rules will apply.

AETR rules apply to journeys outside of the EU, including Norway and Switzerland.

There are exceptions, such as for vehicles used in emergencies or rescue operations. There are also additional rules regarding urgent circumstances.

From 1 June 2026, zero-emission goods vehicles such as electric vehicles, with a total permitted weight more than 3.5 tonnes to 4.25 tonnes, do not have to comply with tachograph rules.

Included in the Assimilated rules (previously EU rules) are:

• Driving 9 hours a day

• Resting for at least 11 hours every day

• Drivers' hours breaks include a break or breaks totalling at least 45 minutes after no more than 4 hours 30 minutes driving.

This information is recorded on the lorry tacho to ensure a clear audit, ensure driver safety, and be compliant.

Tachograph exemptions

The rules are strict, but there are exemptions for certain vehicles and operations. These exemptions offer flexibility for vehicles that fall under a specific weight class or for transport that remains within national borders.

For example, vehicles under 7.5 tonnes that are not used for commercial transport or certain agricultural vehicles are often exempt.

There are other vehicles that may be exempt from the assimilated drivers’ hours rules, including journeys within the UK only. Vehicles used for the carriage of passengers on regular services with a route that does not exceed 50 km are also exempt. As well as vehicles used in the non-commercial transport of humanitarian aid, used in emergencies or rescue operations.

It is crucial to know the exact conditions to determine whether your vehicles are eligible. Transport companies must carefully evaluate the exemption criteria to ensure compliance with legislation and avoid unnecessary fines.

To check all of the exemptions, see government guidance.

What to do now to comply with new tacho laws

If your vehicles are over 2.5 tonnes in international transport for hire and reward, then you need to be ready for the 1 July 2026 deadline. Here are activities you need to carry out:

1. Audit your fleet

   Check your fleet for any vehicles that fall under the new legislation

2. Upgrade vehicles
   

   Hauliers must upgrade their vehicles with the Smart Tacho 2 to comply with the new legislation. This requires the purchase and installation of new equipment and checking if new driver tachograph cards are needed.

3. Upgrade systems
   

   You may have more vehicles requiring their driver and Vehicle Unit (VU) data to be downloaded, so you need to ensure your systems can manage this.

4.  Update policies and procedures
   Administrative processes must also be adjusted to ensure operator compliance with the new registration and reporting requirements.
5. Train staff and HGV drivers
   Ensure any HGV or LGV driver is trained in the new legislation and update any training materials.

Conclusion

The new tachograph legislation brings challenges and opportunities. Complying with the rules prevents fines and improves efficiency and safety.

Frequently asked questions about UK tacho laws

Do you need a new driver card?

Not necessarily. The Smart 2 tachographs do require new cards, but your current card could be backward compatible.

What are the 4 types of tacho cards?

The four types of tacho cards include the driver card, which is white, the company card, which is yellow, the workshop card, which is red, and the control card, which is blue.

The driver card is for individual drivers and needs to be inserted into the tachograph at the start of the shift. The company card is for transport operators and fleet managers to download the data. The workshop card is for approved tachograph technicians and calibration centres, and the control card is for law enforcement and other authorities.

What is the one-minute rule on a tachograph?

Under EU Regulation 1266/2009, the one-minute rule means the tachograph records your activity based on what activity was carried out the longest within a single calendar minute. So, if the vehicle moved for 33 seconds within a one-minute timeframe, the tachograph logs ‘driving’ for that minute.

What does hire and reward transport mean?

If you carry goods or passengers for payment or any direct/indirect remuneration, then this is classified as hire and reward.

How much does a smart tachograph cost?

The costs of the new Smart Tacho 2 depend on a number of factors. Which parts do or do not need to be replaced? How many will need to be purchased at one time? What type of vehicle requires the tachograph?

Assume at least £1500.00 for the purchase of the tachograph itself. The other parts are custom-made, and an amount cannot be estimated for that. Companies like Scania are offering support with integrating the Tacho Smart 2.

What do the new tachograph rules mean for vans?

The new tachograph rules also apply to certain types of vans or light commercial vehicles. Starting in 2026, delivery vans over 2,500 kg in international transport must have a tachograph. This means that businesses that carry out cross-border transport using vans must comply with the same rules as lorries. There are exemptions for national journeys, but you should check whether your vehicles qualify for them.
