6.3 Digital & Analogue Tachograph Operation
Key Takeaways
- Tachograph duties apply only when the operation is in scope; regular passenger services whose route does not exceed 50 km and some other operations are exempt.
- Use Slot 1 for the active driver's card and Slot 2 for the co-driver; make complete manual entries and record driving, other work, availability and rest accurately.
- If a card is lost, stolen or defective, apply or report within seven calendar days and use signed printouts; driving without it is limited to 15 calendar days except for a necessary return to base.
- At a roadside check the driver must now be able to produce records for the current day and the previous 56 days.
- Operators normally download driver-card data at least every 28 days and vehicle-unit data at least every 90 days, and retain records for audit.
Purpose and Statutory Role of Tachographs
A tachograph records driving, speed, distance and activity so that in-scope hours rules can be enforced. Most larger coach operations are in scope, but not every vehicle with more than nine seats uses one on every journey. Examples include the exemption for regular passenger services on routes not exceeding 50 km and, under stated conditions, certain non-commercial minibuses. Confirm the operation's status and any required exemption declaration.
Analogue vs Digital Smart Tachographs
Over recent decades, tachograph technology in Ireland has evolved from mechanical paper-disc systems to advanced digital smart devices.
Analogue Tachographs (Paper Chart Discs)
- Operation: Utilizes a wax-coated paper chart disc that rotates on a clockwork mechanism inside the tachograph unit. Steel styluses scratch lines into the wax coating to record speed, distance, and driver mode.
- Manual Chart Entries: Before inserting a chart disc into the vehicle unit, the driver must manually write the following details in the centerfield of the disc using a pen:
- Driver's surname and first name.
- Location where the chart record started (e.g. Dublin).
- Date of chart placement.
- Vehicle registration mark (VRM).
- Initial odometer reading (odometer start figure).
- 24-Hour Replacement Rule: An analogue chart disc has a maximum recording capacity of 24 hours. If a driver's shift exceeds 24 hours, or when starting a new day, the disc must be removed and replaced with a fresh disc.
Digital Smart Tachographs (Generation 1 & Generation 2)
- Operation: Digital tachographs record encrypted operational data electronically to an internal Vehicle Unit (VU) memory and onto the driver's personal microchip-embedded Digital Driver Card.
- Smart Tachograph Features (EU Mobility Package): Modern Smart Tachographs (Version 2 / Gen 2) feature integrated GNSS (GPS) satellite positioning to automatically log border crossings, vehicle location every 3 hours of accumulated driving, and remote Dedicated Short-Range Communication (DSRC) for roadside enforcement screening by RSA officers.
Digital Driver Card Procedures & Operational Rules
Every professional bus driver operating a vehicle fitted with a digital tachograph must possess a valid Digital Driver Card issued by the Road Safety Authority (RSA).
Daily Card Usage Protocols
- Slot Insertion: At the beginning of the work shift, before driving or performing any work, the driver must insert their driver card into Slot 1 of the digital tachograph unit (the active driver's slot). In a multi-manning operation, the co-driver inserts their card into Slot 2.
- Manual Entry Prompts: Upon card insertion, the tachograph display prompts the driver to confirm manual inputs. The driver must manually log:
- Country of shift commencement (e.g. 'IE' for Ireland).
- Any activities (work, rest, or availability) undertaken since the card was last removed from a tachograph.
- Shift End Ejection: At the conclusion of the working shift, the driver must select the menu option to eject the card, confirming the country code of shift end.
Lost, Stolen, or Damaged Driver Cards
Driving without a valid digital driver card is strictly prohibited, except under specific emergency procedures:
- RSA Notification: The driver must report the loss, theft, or malfunction to the RSA within 7 calendar days.
- Maximum 15-Day Driving Provision: The driver may continue driving without a card for a maximum period of 15 calendar days (or longer only if necessary to return the vehicle to its operational base), provided they generate daily printouts.
- Daily Printout Mandatory Procedure: At the start of each day, the driver must produce a printout from the vehicle unit, write their name, driver card number or driving licence number on the back, and sign it. At the end of the shift, they must produce a second printout, record all non-driving activities, and sign it.
Tachograph Mode Selector Symbols
Drivers must manually select the correct activity symbol on the tachograph interface whenever their duty status changes. Misrepresenting activity (such as setting the tachograph to 'Rest' while loading passenger luggage) constitutes statutory falsification.
| Symbol | Mode Name | Statutory Definition & Application Examples |
|---|---|---|
| ☸ | Driving | Automatically selected by the tachograph as soon as the vehicle moves. Cannot be selected manually. |
| ⚒ | Other Work | Manually selected for all non-driving tasks: vehicle walk-around checks, loading/unloading luggage, cleaning the bus, ticket administration, maintenance. |
| ⧈ | Availability | Manually selected for periods when the driver is not required to be at their post but must remain available for calls (e.g. waiting for passengers to return, accompanying a vehicle on a ferry/train). |
| 🛏 | Rest / Break | Manually selected for mandatory statutory 45-minute breaks, split breaks, daily rest periods, and weekly rest. |
Current 56-Day Roadside Record Requirement
Since 31 December 2024, a driver at a roadside inspection must be able to produce the current day and the previous 56 days of relevant activity. Depending on the equipment and work, that evidence includes the driver card, analogue charts, manual records and vehicle-unit printouts. The former 28-day roadside window is no longer the current answer.
A driver using an occasional-passenger flexibility may also need completed journey forms and copies covering the relevant previous 56 days. Records must be legible and truthful; missing activity should be entered manually or documented using the permitted printout procedure rather than disguised as rest.
Employer Data Downloading Requirements
Transport operators must regularly download and archive tachograph records to prevent data loss:
- Driver Card Data Download: Must be downloaded at least once every 28 calendar days.
- Vehicle Unit (VU) Data Download: Must be downloaded at least once every 90 calendar days.
- Record Retention: Employers must retain all tachograph records for at least 12 months for RSA audit inspection.
