Tachograph belongs to On Board Recording Devices. Their development have been beginning since before The Second World War. The first on board recording devices is analog tachograph which obligatory to using to introduce in USA in 1939. This paper includes main rules of function of analog tachograph and digital tachographs system using in road transport in European Union.

That the manufacturer of a vehicle or the workshop are obliged to activate the installed recording equipment before a vehicle leaves a place where installation has taken place. For that reason some procedures for different vehicle groups have been developed as follows: if a vehicle is under obligation of installing the recording equipment and it is equipped with such equipment then the activation and calibration of this equipment must be performed, if a vehicle is under obligation of installing the recording equipment and it is not equipped with such equipment then the installation, activation and calibration of this equipment must be performed, if a vehicle is not under obligation of installing the recording equipment and it is equipped with such equipment then the activation and calibration of this equipment must be performed, next this equipment can be switched in a mode OUT OF SCOPE, if a vehicle is not under obligation of installing the recording equipment and it is not equipped with such equipment then the installation of such equipment is not necessary
