In Denmark, three types of permits are available for oversized (“high and wide”) and heavy abnormal transports: “one-only” permits and “general” permits.

  1. General permits are valid for a fixed period of time and either the entire road network known as the “Danish Heavy Load Grid”.

  2. Route permits are valid for a fixed period of time and a predefined route.

  3. One-only permits are valid for a one-time transport along a specifically applied route.

All abnormal transports must bring along a print about curfew periods and special condition for abnormal transports, which can be down printed from Danish homepage under the subject Erhvervstransport.

The Heavy Load Grid in Denmark is a road network which is preclassified for heavy transports. Within this road network, the classification on permissible loading of all bridges and permissible roadwear on road pavements are available.

Hauliers who wish to transport an abnormal load must submit an application to one of eight possible police offices. The police authority in South and Southern Jutland at Padborg is responsible for issue of permit for all international transports. The application must include a certificate for the vehicle used to carry the goods. This certificate is issued by the Danish Motor Vehicle Inspection Office.

For heavy transports, a “Transport Classification Certificate” from the Danish Road Directorate is also required. The Transport Classification Certificate provides a technical description of the heavy transport, including information from the Haulier regarding distances be-tween axles, total laden weight, track width, distances between tyres, etc. The transport will be classified based on this information and assigned to appropriate road and bridge classes. The classification of the transport is carried out by the company COWI A/S in Kongens Lyngby on authority of the Danish Road Directorate.

The police check whether the application is complete and correct. If the transport should be carried out on a road not included in the Heavy Load Grid or if the weight of the transport exceeds a certain value, the police will consult the involved road authorities. These authorities assess any missing classifications for the specified route and decide whether the heavy transport can be carried out under certain conditions. About 90 % of all applications, however, can be processed by the police without the involvement of the road authorities. For oversized transports the police check the pasability of the applied transport route after consulting the involved road authorities.

Permit applications can usually be processed in one to four workdays. A slightly longer processing period, however, is required in cases involving the road authorities. No fees are generally charged in Denmark for the entire application process. Special investigations and arrangements required to carry through the abnormal transport are fully paid by the applicant.
