Digital tachographs are devices fitted to buses and trucks. They record the amount of time drivers spend driving and resting, as well as capturing data about the vehicle. Digital tachographs are now mandatory in the EU
Under EU and national law, the cab of trucks and buses must be fitted with recording devices known as tachographs. Their function is to record the driving times, breaks and rest periods of individual drivers. Vehicle speed, distance travelled and other related metrics are also logged.
Data is stored in mass memory inside the unit and on driver-specific smart cards. In Ireland, the Road Safety Authority is the legal body responsible for issuing these cards.
The records must be available for inspection by enforcement officers to ensure that the laws governing driver hours and rest times are fully complied with.
Failure to comply with these requirements could result in prosecution by the RSA. Although most commercial vehicles must carry a tachograph, there are some classes of vehicle that are exempt.
Digital tachographs became mandatory within the EU in May 2006. They replace the old analogue recording devices in all new commercial trucks and buses.
Central to the introduction of digital tachograph technology is the provision of smart cards for use by drivers, companies, calibration workshops and enforcement officers.
There are four types of Tacograph cards.
The personal digital tachograph driver card is a credit card-sized plastic card that contains a microchip. The card can store all relevant driver data required for EU Drivers’ Hours regulations including break and rest times.

A company card allows you to access the data stored in the digital tachograph. You will also need it to protect your data in the vehicle unit (VU) if you hire in or sell a vehicle.

Workshop tachograph cards are issued to authorised workshops only. The card allows calibration of the digital tachograph itself.
