259(1)The Registrar, upon registering any truck, truck tractor, trailer, or semi-trailer under the laws of this Province, or any bus may require such information and may make such investigation or test as is necessary to enable him to determine whether the vehicle may safely be operated upon the highways in compliance with this Act, and he shall register every such vehicle for a permissible gross mass not exceeding the limitations set forth in the regulations.

259(2)The Registrar may insert in the registration certificate issued for every such vehicle the gross mass for which it is registered, and if it is a motor vehicle to be used for propelling other vehicles he may separately insert the total permissible gross mass of the motor vehicle and other vehicles to be propelled by it, and he may also issue a special plate with the gross mass stated thereon, which shall be attached to the vehicle and be displayed thereon at all times.

259(3)Notwithstanding the gross mass set out in a registration certificate, the vehicle or combination of vehicles is deemed to be registered only for the maximum gross mass allowable under the regulations for that type of vehicle or combination of vehicles.
