What's the difference between commercial and non-commercial road transport?

What you said can't be found in the current road transport regulations.

Provisions on the Administration of Road Passenger Transport and Passenger Stations

Article 3 The term "road passenger transport operation" as mentioned in these Provisions refers to the commercial road passenger transport activities that transport passengers by bus and provide services to the public, including shuttle bus (overtime bus) passenger transport, chartered passenger transport and tourist passenger transport.

Regulations on Road Freight Transportation and Station Management

Article 2 The term "road freight transport operation" as mentioned in these Provisions refers to the commercial road freight transport activities that provide public services to the society. Road freight transport includes ordinary road freight transport, special road freight transport, large-scale road freight transport and road dangerous goods transport.

As can be seen from the above two provisions, commercial road transport has two remarkable characteristics: one is to provide services to the public, and the other is commercial. The so-called commercial nature is the road transportation that provides services for the society, and the settlement or payment of various expenses. In the process of commercial road transportation, there are various settlement methods, including freight, handling fee and price, freight, handling fee and engineering fee, freight and labor fee, contract fee, etc.

Road transport that meets the above two characteristics belongs to commercial road transport, and vice versa.
