51.30. By what are the maximum permissible mass of cargo transported by a vehicle and the maximum permissible axle loads determined?
UAЧим визначаються величина максимально дозволеної маси вантажу, що перевозиться транспортним засобом, і величини максимально дозволених навантажень на осі?

This exam question from the Traffic Rules of Ukraine concerns the safe transportation of cargo and the technical limitations of vehicles. Proper understanding of the maximum permissible mass and axle loads directly affects handling, braking distance, vehicle stability, and road wear, which is why these standards are regularly checked in the theoretical exam.
The question tests knowledge of the section of the Traffic Rules regarding cargo transportation, specifically the requirements of paragraph 22.1: the cargo mass and the distribution of the load on the axles must not exceed the values specified for the particular vehicle. It is also related to the term "permissible maximum mass" from paragraph 1.10, which clearly states that this limit is set by the technical specifications of the vehicle (manufacturer data, plate, documentation).
If you analyze the options, the body capacity does not determine the permissible mass, since volume and load capacity are different things. The actual mass of the current cargo only describes what is loaded now, but does not set the limits that can be exceeded. The option about "regulatory authorities' standards" can be misleading, because within this traffic rule, the reference point is precisely the technical parameters of the specific vehicle; the driver must refer to them and not allow overloading either by total mass or by axle load.
Clause 22.1
The mass of the cargo being transported and the distribution of axle loads must not exceed the values specified by the technical specifications of this vehicle.
Brief application: it is the technical specifications of the specific vehicle that establish the maximum permissible cargo mass and allowable axle loads, which must not be exceeded during transportation.
Clause 1.10 (term "Permissible maximum mass")
Permissible maximum mass — the mass of an equipped vehicle with cargo, driver, and passengers, as established by the technical specifications of the vehicle as the maximum allowable. The permissible maximum mass of a road train is the sum of the permissible maximum masses of each vehicle that is part of the road train.
Brief application: The Traffic Rules directly state that the "permissible maximum mass" is determined by the technical specifications of the vehicle, i.e., by the manufacturer/documentation of the vehicle.
Therefore, the correct answer is "By the technical specifications of the vehicle," given that according to the definition in the Traffic Rules and the requirement of clause 22.1, the cargo mass and axle loads must not exceed the values established by the technical specifications of the vehicle.
When it comes to transporting cargo, it is important to understand in the Traffic Rules that the restrictions apply not only to the total weight, but also to how this weight is distributed across the vehicle’s axles. In other words, it is not enough to simply know how many kilograms you have loaded — both the total weight and the load on each axle must remain within the established limits.
Clause 22.1 of the Traffic Rules of Ukraine directly states that the cargo weight and axle load distribution must not exceed the values specified for that particular vehicle. These values are not taken "out of thin air" and are not determined at the driver’s discretion, but are set by the manufacturer and recorded as parameters for a specific model.
This is related to the concept of the maximum permitted mass: it includes the weight of the equipped vehicle itself together with the cargo, driver, and passengers, and is set as the maximum allowable for that vehicle. That is, the limit is determined not by general rules for everyone, but by the technical data of the specific vehicle (for example, in the documentation or on the manufacturer’s plate). The same applies to the axles: even if the total weight seems "within the norm," but the cargo is shifted so that the rear axle is overloaded, this is already a violation, because the permissible axle load has been exceeded, which is also specified by the technical characteristics.
Therefore, the correct answer is "By the technical specifications of the vehicle," since the Traffic Rules require not to exceed the cargo weight and axle loads established by the manufacturer as permissible parameters for this particular vehicle.
