About this plate
Full trailers and semi-trailers not permanently coupled to their tractor. The scope wording matters: a semi-trailer that IS permanently coupled is not separately plated. 《机动车登记规定》第九条 confirms the separate registration at rule level. One plate, rear only, on the tall 440x220 layout it shares with the large-vehicle rear plate.
