Direction des Infrastructures, de la Topographie et des Transports Terrestres

The Direction des Infrastructures, de la Topographie et des Transports Terrestres (DITTT) is a French governmental body responsible for overseeing matters related to infrastructure, topography and terrestrial transport. Its mandate includes the planning, maintenance and regulation of transport networks as well as the production and management of geographic and topographic data. The organisation also operates the administrative systems that handle vehicle registrations and the issuance of driver’s licences for residents. By maintaining these registers, DITTT supports law enforcement, road safety initiatives and the provision of public services linked to mobility. Its work ensures that transport infrastructure meets national standards and that cartographic information is accurate for both civilian and military use. The agency collaborates with other ministries, local authorities and national agencies to coordinate projects and share data essential for territorial development.

Headquartered in France, DITTT operates as a directorate within the broader structure of the French state, exercising regulatory authority over the sectors within its scope. In July 2025 the organisation experienced a cyberattack that compromised its vehicle registration and driver’s licence databases, prompting an immediate response from national cybersecurity teams. Following the incident, DITTT worked with governmental authorities to contain the breach, secure external application access and launch an investigation into the attack’s origin. The agency filed a judicial complaint to pursue accountability and committed to providing ongoing updates as the investigation proceeds. This event highlighted the critical role DITTT plays in safeguarding sensitive personal and administrative data linked to France’s transport systems.
