For each tunnel located on the territory of one Member State, whether it is in the design, construction or operating stage, the administrative authority shall identify as Tunnel Manager the public or private body responsible for the management of the tunnel at the stage in question. The administrative authority itself may perform this function.

For each tunnel located on the territory of two Member States, the two administrative authorities or the joint administrative authority shall recognise only one body in charge of the operation of the tunnel.

Any significant incident or accident occurring in a tunnel shall be the subject of an incident report prepared by the Tunnel Manager. This report shall be forwarded to the Safety Officer referred to in Article 6, to the administrative authority and to the emergency services within a maximum period of one month.

Where an investigation report is drawn up analysing the circumstances of the incident or accident referred to in paragraph 3 or the conclusions that can be drawn from it, the Tunnel Manager shall forward this report to the Safety Officer, the administrative authority and the emergency services no later than one month after he/she receives it himself/herself.
