Rules for lorries and buses

Non-Danish vehicles

Owners of non-Danish vehicles that were first registered before the applicable current requirements must register the vehicle with documentation for a retrofitted diesel particulate filter or Euro standard in order to drive legally in the low emission zones.

You must register your vehicle no later than on the same day that you drive into the low-emission zone.

If you fail to register your vehicle and submit relevant documentation, you may risk an administrative fine of DKK 1,000.

Rules as of 1st July 2020

Older diesel lorries and buses aren’t allowed into the low emission zones unless they are fitted with a particulate filter. The new low emission zone rules for lorries and buses came into force on 1st July 2020.

Older diesel-powered vehicles (lorries and buses) over 3.5 tonnes must be fitted with a particulate filter to drive and park in the low emission zones. A bus is classed as a vehicle designed to be used by more than nine people including the driver. A diesel-powered motorhome over 3.5 tonnes with more than nine seats including the driver is defined as a bus and the same rules apply.

Rules for driving lorries and buses in the low emission zones

  • Buses and lorries must be registered on or after 1st January 2015 or have a diesel particulate filter fitted to have access to the low emission zones.
  • For heavy vehicles that comply with at least Euro standard 6, the particulate filter requirement is considered to have been met and these vehicles are allowed to drive in the low emission zones.
  • Non-Danish vehicles that don’t meet the above date requirements must always be registered online before driving in the low emission zones. Find out more about registering foreign vehicles here.

Are you in doubt about whether your vehicle complies with the rules?

How your lorry or bus can comply with the rules

If your vehicle doesn’t comply with the low-emission zone rules, the vehicle must have a particulate filter retrofitted in order to be able to drive legally in the Danish low emission zones.
Danish trucks and buses

The detailed rules for retrofitting particulate filters for lorries and buses are laid down in:

• Legislative decree no. 396 of 22/03/2022 on requirements for diesel-powered trucks, buses and vans in municipally determined low emission zones, etc. Pursuant to section 5, the installation of an efficient particulate filter must be documented by a declaration signed by the filter supplier, cf. appendix 1.

Applies solely to Danish lorries and buses: Before the declaration from the filter supplier is presented at the inspection centre, the declaration must be submitted to the Danish Environment Protection Agency at

The Danish Environment Protection Agency then assigns an identification number, which the owner or user must affix to the declaration.

The rules for lorries and buses do not apply to:

  • Vehicles registered in Denmark driven by veterans. This must be stated in the Danish Vehicle Register (DMR).
  • Vehicles registered abroad, which are more than 30 years old.
  • Vehicles used by the military, police, emergency services or similar emergency services, if these vehicles don’t normally drive in a low emission zone and there is an extraordinary need to use the vehicle in a low emission zone, or the vehicle is used for training activities. Contact the Danish Environment Protection Agency for further information.

In case of illegal driving in the Danish low emission zones, the fine is DKK 12,500 for lorries and buses and DKK 1,500 for vans
