explanation:
Light motorcycle: Maximum design speed≤50km/h, and its cylinder total work volume≤50ml.

Motorcycle: Unloaded weight<400kg. Maximum design speed>50km/h or engine cylinder work volume>50ml.

Semi-trailer tractor: Tractor designed for pulling semi-trailer. The weight of vehicle categorizing means the sum:weight which tractor is in running condition+maximum vertical dead load which transferred from semi-trailer to tractor+maximum design load of tractor(if available).
