Currently, in my country, tachographs are installed only on vehicles carrying out international traffic (AETR agreement). When transporting inside the country, no devices are used to monitor the work time of drivers. Tell me, where I can see publications on the assessment of accidents before and after the introduction of tachographs (or other control devices) for transportation inside the country? Where can I see the methodology for proving the need to introduce tachographs? any information on this topic?
