Rules for lorries and buses

Older diesel-powered lorries and buses weighing over 3,500 kgs are not allowed in the low emission zones unless they are fitted with a particulate filter or are at least Euro VI.

Non-Danish vehicles

Owners of non-Danish diesel-powered vehicles, which are registered the first time before the current date limits, must register the vehicle with documentation for the vehicle being fitted with a diesel particulate filter or the Euro standard in order for it to be used legally in the low emission zones.

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

If you fail to register your non-Danish vehicle and submit the relevant documentation, you risk receiving an administrative fine of DKK 1,000.

Rules as of 1^st July 2020

Older diesel-powered lorries and buses are not allowed in 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 1^st July 2020.

Older diesel-powered vehicles (lorries and buses) weighing over 3,5 kgs must be fitted with a particulate filter to be used legally in the low emission zones. A bus is classified as a vehicle designed to be used by more than nine people including the driver. A diesel-powered motorhome weighing over 3,5 kgs with more than nine seats including the driver's seat 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 1^st January 2015 or later, or have a diesel particulate filter fitted to access the low emission zones.
For heavy vehicles that comply with at least Euro VI, the particulate filter requirement is considered to be met and these vehicles are allowed in the low emission zones.
Non-Danish vehicles that do not meet the above date requirements must always be registered online. Read more about registering non-Danish vehicles here.

How your lorry or bus can comply with the rules

If your vehicle does not comply with the low emission zone rules, the vehicle must have a particulate filter retrofitted in order to be used legally in the Danish low emission zones.

Danish lorries and buses

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

Legislative decree no. 1066 of 03/08/2023 on requirements for diesel-powered lorries, 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 Environmental Protection Agency at miljozoner@mst.dk.

The Danish Environmental 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 as vintage. 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 do not usually 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.
