Yes, there is a mapping restriction class specifically for emergency
vehicles. That way (for example) you could prevent a turn at an
intersection for motorcars, but allow it for emergency vehicles. You
can change the routing mode (i.e. pedestrian, bicycle, bus, taxi,
etc.) in the GPS and it will change the permissible routes.
