Large vehicles requiring a smart tachograph

Any vehicles first registered on or after 15 June 2019, which require a tachograph to be fitted, will need to have a type 1C unit tachograph. These are also called smart tachographs.


With many improvements, such as satellite positioning data and increased security, the new devices are designed to foster greater compliance with the drivers’ hours rules by making it more difficult to tamper with the devices; they may also reduce administrative processes.


The most important new feature is the introduction of satellite positioning data. The new devices will take a GPS reading at the start and end of duty and every three hours of accumulated driving.


Drivers of vehicles which require tachographs, but fail to have one fitted or have the wrong type fitted could face enforcement action.

Read more about the rules on drivers hours and which vehicles require a tachograph to be fitted on the gov.uk website.
