Road Transport Authorities are public institutions responsible for regulating, supervising, and coordinating the movement of goods and vehicles on the road network. Their mission is to ensure that road freight transport is carried out safely, legally, and efficiently, in line with both national regulations and international standards.
A core responsibility is the regulation of vehicle dimensions and maximum weight limits, in accordance with agreements such as the UNECE 1958 and 1997 Conventions, the EU Weights and Dimensions Directive, and ADR for the transport of dangerous goods. These rules are essential to protect infrastructure, ensure road safety, and maintain fair competition among operators.
Key functions of a Road Transport Authority include:
Issuing operating licenses for transport companies and professional drivers
Monitoring compliance with weight, dimension, and axle load limits
Roadworthiness inspections and technical certifications
Enforcing rest time and driving hour rules, especially under EU Regulation 561/2006
Monitoring and authorising special transport operations, such as oversized or heavy cargo
Overseeing the safe transport of dangerous goods under the ADR convention
Promoting environmental standards, including low-emission zones, fleet modernisation, and alternative fuels
Supporting digitalisation, such as the use of electronic consignment notes (e-CMR), tachographs, and transport telematics
Road Transport Authorities also play a coordination role with customs, police, and road infrastructure managers—especially at border crossings and logistics nodes, where multimodal transport needs clear regulatory continuity.
In many regions, these authorities are now involved in sustainability strategies, helping to implement modal shift policies and support the development of urban logistics frameworks, green corridors, and zero-emission freight initiatives.
In short, the Road Transport Authority is the guardian of fair, safe, and sustainable road freight. By enforcing standards on vehicles, operators, and infrastructure use, it ensures that road transport remains a reliable, regulated pillar of global supply chains.
