How do I know if there is a disruption on my line?

Updated on Jul 20 2026

In the Traffic Information section of the Île-de-France Mobilités website and application, each disrupted line is indicated by a coloured icon indicating the level of disruption:

On the Île-de-France Mobilités app

To consult the traffic information for a line:

  • Open the Île-de-France Mobilités app.
  • Go to the Traffic Information section.
  • In the section of the mode of transport concerned: choose the desired line or enter its number directly in the search bar.
  • Consult the traffic information (disruptions / works ) of your current or future line, up to 30 days in advance, by clicking on the "Coming soon" tab.

The pictograms displayed next to the line logos make it possible to identify at a glance their level of disturbance. Find below the meaning of each of these pictograms.
