Moped rules driving license and why tuning is illegal
Small and large moped — and the consequences of tinkering with the speed
The moped occupies a special place in Danish traffic: it is often the first motorized vehicle young people own and maintain themselves. Precisely because of this the rules around it are tighter than many expect — and as a mechanic you are part of the chain that ensures the rules are followed in practice.
§Small and large moped
Danish legislation distinguishes between two types of mopeds based on design maximum speed. A small moped (often called 'moped 30') is designed for a maximum of 30 km/h, may be ridden on cycle paths, and has a yellow license plate. A large moped (often called 'moped 45') can reach up to 45 km/h by design, must follow the same rules as other motor vehicles on the roadway itself, and has a white license plate. The distinction is not cosmetic — it determines where the vehicle may be operated and what licence the rider must have.
§Driving license and insurance
Driving license for a moped falls under category AM, which is divided into AM for small moped and AM for large moped. If you're born after a certain date, you must generally have at least a small AM license to legally drive a moped. All registered mopeds must also have mandatory third-party insurance — without it the driver is not covered if an accident happens, and it's illegal to ride uninsured.
- 01Small moped (30 km/h): bike path, yellow plate, AM small moped at minimum
- 02Large moped (45 km/h): traffic lane as other traffic, white plate, AM large moped
- 03Statutory instruction
- 04Tuning makes moped illegal — it is not mechanic job to do
§The mechanic's responsibility
When a customer asks to 'turn up the speed', it's your professional and legal duty to say no and explain why. It's not about being boring—a tuned moped is slower at braking relative to speed, less stable, and puts both the customer's and others' safety at risk, while breaking the law. A professional workshop lives by its good name, and that name is built on customers being able to trust that work is performed legally and safely.
§The rules follow the technology
As e-scooters, e-bikes, and e-mopeds have arrived, regulations have been expanded to cover them as well — often with similar distinctions between speed classes and requirements for registration and insurance. As a mechanic, you must therefore keep up to date, not just on the vehicle's actual technique, but also on what rules apply to the specific type you're working with.
