On 22 and 23 May 2024, a coordinated effort by the Infrastructure Inspectorate of the Republic of Slovenia, the Slovenian Police and the Financial Administration of the Republic of Slovenia, with support from the European Labour Authority (ELA), led to targeted and increased checks in international road passenger transport.

A total of 293 buses were subjected to roadside checks: 97 from domestic operators, 143 from European operators and 53 from third-country operators. The traffic enforcement operation revealed a variety of irregularities. Violations ranged from the non-operation of regular services to non-compliance with authorisations, timetables and routes, along with improperly filled-out journey forms. Additionally, several breaches of social legislation were identified, such as missing data for services performed over the previous 28 days, concealment of data, driving with a different driver card, driving without a driver card, incorrect use of tachograph switch mechanisms, absence of manual entries in the tachograph, and insufficient weekly rest periods for drivers. Technical inspections also revealed deficiencies and defects. As a result of an extraordinary technical inspection, two buses were promptly removed from service due to critical issues identified in their braking systems and steering mechanisms. Furthermore, violations pertaining to the undeclared work of bus drivers, the provision of occasional services without proper notification and the misuse of on-board units (OBUs) by toll road users were noted.

This year's bus traffic enforcement operation is a continuation of joint activities initiated last year. Similar roadside checks were carried out last April at the Dul motorway rest area, followed by a joint traffic enforcement operation in Croatia in December 2023. This year's operation saw the participation of observers from various international authorities. Representatives from the Croatian inspection authorities (traffic inspectorate) and the Croatian police (mobile unit of the traffic police) were in attendance, along with representatives from the Austrian and German police forces. Additionally, representatives from the European Roads Policing Network (ROADPOL), the European Labour Authority (ELA) and the European Commission's Directorate-General for Mobility and Transport were present to oversee the enforcement activities.
