In which case is it mandatory for trailers and semi-trailers to have their own circulation permit?

Question

DentroTest · Accepted Answer

Regulations distinguish administratively and legally between trailers based on their Maximum Authorized Mass (MAM). Light trailers (MAM ≤ 750 kg) do not need their own circulation permit or independent license plate (they display the towing vehicle's plate), requiring only their Technical Inspection Card. However, non-light trailers (those with a MAM exceeding 750 kg) are considered independent vehicles; therefore, it is mandatory to register them and for them to have their own circulation permit, a red license plate, and insurance.
