Step-by-step guide to conducting routine tachograph checks

For HGV operators, tachographs are an essential tool in monitoring driving hours and ensuring compliance with legal regulations. Routine tachograph checks are not only vital for avoiding fines and penalties but also play a crucial role in promoting road safety. However, not every driver or fleet manager fully understands how to conduct these checks properly, leading to costly mistakes. 

This step-by-step guide will walk you through how to carry out routine tachograph checks efficiently while emphasising the importance of professional training through HGVC.

What is a tachograph and why is it important?

Before diving into the routine checks, let’s first understand what a tachograph is and why it is so crucial for HGV drivers.

  • A tachograph is a device installed in commercial vehicles that records driving time, speed, and distance. Its primary purpose is to ensure that drivers do not exceed the legal driving hours and take the necessary rest periods to prevent fatigue-related accidents.

Failing to monitor and check tachograph data can lead to severe legal consequences, including hefty fines, vehicle impoundments, and reputational damage. 

At HGVC our comprehensive HGV training includes routine tachograph checks as part of a seamless driver management solution.

Step-by-step guide to routine tachograph checks

STEP 1: Ensure your tachographs are functioning properly

According to the UK government, all tachographs used for recording drivers’ hours, whether analogue, digital, or smart, must be properly installed, calibrated and sealed. The first step in conducting routine tachograph checks is to understand the key components of the tachograph system and ensure that all devices are functioning correctly. A malfunctioning tachograph can result in inaccurate data recording, which could lead to compliance violations and safety hazards.

What to check:

  • Ensure that the device powers on and displays correctly.
  • Verify that it is receiving power from the vehicle’s electrical system.
  • Check for error messages on the screen or warning indicators.

Training at HGVC emphasises the importance of starting every shift with this fundamental step to ensure that drivers operate within legal limits and maintain accurate records.

STEP 2: Check calibration and inspection dates

Tachographs must be regularly calibrated to ensure they record accurate data. Calibration checks are essential, as an out-of-date calibration can render your records invalid and lead to legal penalties.

What to check:

  • Verify the tachograph’s calibration date. This information is typically printed on a sticker on the device or available in the system menu.
  • Ensure that calibration has been carried out by an approved technician and falls within the legal calibration period (For analogue tachographs: inspection every two years and calibration every 6 years. For digital and smart tachographs: inspection every two years and calibration every 2 years. 

HGVC’s training programs teach drivers and fleet managers how to read and interpret calibration data, ensuring full compliance.

STEP 3: Inspect driver cards and download data regularly

Driver smart cards from the DVSA are an essential component of the tachograph system, and it is critical to ensure they are properly inserted before each shift – and throughout the shift, including during breaks and rest periods. 

Regular data downloads from both the driver card and the vehicle unit are required to maintain compliance with UK regulations. Drivers must also remember to transfer their driver smart card to their new tachograph unit when switching to a new vehicle. 

What to check:

  • Ensure the driver card is inserted into the tachograph correctly and that it has been read by the system.
  • Download data from the driver card at least every 28 days and from the vehicle unit every 90 days, as required by law.

STEP 4: Monitor driving time and rest periods

One of the most critical elements of tachograph checks is monitoring driving times and rest periods. The law is clear: drivers must not exceed a certain number of driving hours and must take regular breaks to prevent fatigue. Failing to follow these rules can lead to penalties and dangerous road conditions.

What to check:

  • Ensure that driving hours, breaks, and daily/weekly rest periods comply with legal regulations.
  • Review tachograph records regularly to ensure no discrepancies or violations.

HGVC’s training programs include in-depth guidance on interpreting tachograph data, ensuring that drivers fully understand the rules and how to adhere to them during their shifts.

STEP 5: Check for driving anomalies

Anomalies in the tachograph data, such as driving without a card or exceeding speed limits, can lead to serious consequences. Regular checks can help identify and rectify these issues early, preventing penalties and ensuring the safety of the driver and other road users.

What to check:

  • Look for any periods where the vehicle was driven without a driver card inserted.
  • Identify any instances where the vehicle speed exceeded legal limits.

With HGVC’s training, drivers are taught to recognise and avoid these common pitfalls, helping your company maintain compliance and reduce the risk of accidents.

STEP 6: Review rest periods and breaks

Ensuring that rest periods and breaks are being taken correctly is essential for both safety and compliance. Drivers are required to take breaks during their shifts, and tachographs are instrumental in recording whether these breaks were taken at the correct intervals. Using the tachograph, drivers can switch their mode from driving to rest to availability to other work. 

What to check:

  • Review the data to confirm that the required breaks were taken during driving shifts.
  • Verify that the total number of rest hours meets legal requirements.

At HGVC, we teach drivers to manage their schedules effectively, balancing driving time with mandatory rest periods to optimise safety and compliance.

STEP 7: Conduct periodic data audits

Even with regular downloads and checks, conducting periodic audits of tachograph data is critical to ensure there are no overlooked issues. These audits help identify trends in driver behaviour and ensure that all legal requirements are being consistently met.

What to check:

  • Perform data audits every few months to identify any discrepancies or recurring issues.
  • Cross-reference tachograph data with other records, such as fuel logs and maintenance records, to ensure consistency.

The consequences of failing to conduct routine tachograph checks

Failing to conduct regular tachograph checks can lead to severe consequences, both for drivers and the company. Here are some of the key risks:

  • Legal penalties: Companies that fail to comply with tachograph regulations can face hefty fines, impounded vehicles, and even loss of operator licenses. Non-compliance can also affect your company’s reputation, making it harder to secure contracts.
  • Increased accident risks: Without proper monitoring, drivers may unintentionally exceed their legal driving hours, increasing the risk of fatigue-related accidents. Fatigue is one of the leading causes of accidents involving HGVs, and tachographs play a crucial role in preventing these incidents.
  • Loss of revenue: Compliance violations and accidents can disrupt operations, leading to delays and missed deliveries. In a highly competitive industry, this loss of revenue can be devastating for businesses, especially if it leads to lost contracts or increased insurance premiums.

The Importance of Routine Tachograph Checks

Conducting routine tachograph checks is more than just a legal requirement – it’s a vital aspect of safe and efficient HGV operations. HGVC are committed to helping companies and drivers understand the importance of tachographs and providing the necessary training to ensure compliance.

By partnering with HGVC, you can rest assured that your fleet is in good hands, with drivers who are trained to conduct routine checks accurately and efficiently, keeping your operations safe, compliant, and profitable.
