To obtain the **circulation certificate** necessary for **Personal Mobility Vehicles (PMV)**, it is important to understand who is responsible for this procedure. According to the information provided, the certificate must be obtained by the **manufacturers, importers, or their representatives**. This is because they are responsible for ensuring that the vehicle complies with the necessary regulations and requirements before being put into circulation.

- The **manufacturers** and **importers** have the responsibility to ensure that the PMVs are properly documented and comply with current regulations.
- The **circulation certificate** is an essential document that contains important information about the vehicle, such as the name of the owner, the registration number, and the use of the vehicle, among other data.

Therefore, it is not the user who must request this certificate, nor is it necessary to take a specific driving test for PMVs. The responsibility lies with the manufacturers and their representatives to ensure that the vehicle is ready for use on public roads.
