52.59. What is a control device (tachograph)?
UAЩо таке контрольний пристрій (тахограф)?
Question without image
This examination question from the Traffic Rules of Ukraine concerns the control of transport safety and driver discipline while operating a vehicle. In road traffic practice, a tachograph is needed not "for statistics," but for the official recording of trip parameters and compliance with work and rest regimes, which directly affects the prevention of accidents due to fatigue and speeding.
The question tests knowledge of terms and definitions in the traffic rules, specifically the General Provisions section (point 1.10, the term "Control device (tachograph)"). According to the definition in the Traffic Rules, it is a measuring device installed on a vehicle that, in automatic or semi-automatic mode, displays and records data about movement as well as certain periods of the driver's work.
The answer options essentially present two formulations of the same regulatory content: the first emphasizes that the tachograph is measuring equipment for displaying and recording information about movement and periods of the driver's work; the second specifies this data as the driver's speed and work/rest regime (and, if necessary, those of crew members). That is why, in the theoretical exam, the correct choice is that both formulations correspond to the essence of the definition and complement each other.
Understanding this term helps in practice to correctly interpret the requirements for transport control: based on tachograph data, one can check how long the driver has been driving without breaks, when they rested, whether there were any violations of the regime, as well as which movement parameters were recorded during the trip. This is a typical topic often checked in examination questions on traffic rules, as it is related to driver responsibility and road safety.
Clause 1.10 (term "Control device (tachograph)")
Control device (tachograph) — equipment that is a measuring instrument intended to be installed on vehicles for displaying and recording, in automatic or semi-automatic mode, information about the movement of such vehicles and about certain periods of work of their drivers.
This definition covers both the general characteristic of the tachograph as a control device on a vehicle and its purpose — displaying and recording data about movement and periods of driver work (which in test formulations is often specified as speed and work/rest modes).
Therefore, the correct answer is "Both answers are correct," considering that according to the Traffic Rules, a control device (tachograph) is measuring equipment installed on a vehicle for displaying and recording information about movement and certain periods of driver work.
When a question refers to a control device (tachograph), it means special equipment that is installed directly on the vehicle. Its purpose is not "for convenience," but for the official monitoring of driving parameters and the driver's work during transportation.
According to the definition in the Regulation on Working Time and Rest Time of Drivers (Order of the Ministry of Transport and Communications No. 340), a tachograph is an on-board control device that automatically or semi-automatically records data about the movement of the vehicle. That is, it records, in particular, the speed of movement and other indicators related to the trip.
At the same time, the tachograph is intended for recording work and rest regimes: it displays and records periods of driving, breaks, driver rest, and, if necessary, the rest of the crew members. For example, during an intercity trip, its data can be used to check how much time the driver actually spent driving, when stops were made, and whether the permissible duration of continuous driving was exceeded.
It is important to understand that in the regulatory definition, the tachograph is described from two perspectives at once: as a measuring instrument for recording information about the movement of the vehicle and as a device for registering periods of work and rest of drivers. Therefore, both formulations are essentially correct and complement each other.
Thus, the correct answer is "Both answers are correct," since the tachograph is an on-board control device that records data about movement (in particular, speed) and simultaneously records the work and rest regimes of the driver (and crew members).
