English, French, Spanish and Arabic were used as official languages at the XXVIth World Road Congress. Simultaneous interpretation was provided during the plenary and technical sessions.

Most of the documents presented on this website are available in English, French and Spanish and are presented according to the chosen language of navigation. If a document seems to be missing, we invite you to try temporarily with another navigation language.

In addition, sign language translation was also available at some sessions. This was a much appreciated service.
