Routes for the EMS
A route can only be approved when the EMS can drive safely and in accordance with the Road Traffic Act. To make this possible, it is often necessary to be carried out reconstruction of intersections and roundabouts.
Virtually all state roads are currently approved for the EMS. Besides the state roads over 400 km municipal roads are approved for EMS-vehicles. The road network provides access to over 200 locations across the country. An overview of this can be seen on the Danish Road Directorates map of routes included.
