Fixed-penalties notices for illegal driving in low emission zones are always issued to the registered owner (user) of a vehicle, even if the owner (user) was not the one driving it.
You can avoid criminal liability as an owner (user) if the person who drove the vehicle reports to the Danish Environment Protection Agency that it was they who drove the vehicle at the time of the offence, and they do so within 30 days of receiving the fixed-penalty notice. The driver can acknowledge the offence and pay the fixed-penalty here by clicking on “Claim a fixed-penalty” and then entering the specified reference number and registration number.
Please, note that depending on the circumstances, it may be a criminal offence for an owner (user) of a vehicle to falsely name another person as the driver of the vehicle at the time of the offence. It is also a criminal offence for a person other than the owner (user) to falsely identify themselves as the driver of the vehicle at the time of the offence.
In cases where the Danish Environmental Protection Agency assesses that a criminal offence may have been committed as mentioned above, the Danish Environmental Protection Agency will immediately file a police report.
