The tachograph is a mandatory control device in certain heavy vehicles that continuously and automatically records various data related to the vehicle's movement and the driver's service times. Among the recorded elements are the vehicle's instantaneous speed, the distance travelled in kilometres, and the driver's different periods of activity, such as driving times, other work, availability, and rest. The other options are incorrect because they are incomplete. Although the tachograph records instantaneous speed, limiting its recording only to this parameter or to average speed ignores its fundamental functions of controlling working and rest times and the distance travelled.
