What does the coloured area I see on the map mean?

The blue zone is the zone in which the service is operational, i.e. the zone within which you can drive and park your vehicle (Operating Area). The area outside the operational area is not covered by the service. Here it will be possible to drive the vehicle but it will not be possible to stop or complete the rental.

The red zone is the zone excluded from service operation. In this zone it is not possible to park the vehicle or end the rental.

The orange zone corresponds to a zone in which it is temporarily not possible to park the vehicle or terminate the rental for reasons of public order.
