This exam question from the Traffic Rules of Ukraine concerns safety during cargo transportation and the technical condition of the vehicle. Overloading or improper weight distribution directly affects handling, stability, braking distance, and the risk of accidents, which is why the traffic rules set clear limits that the driver must follow in real driving conditions.
The question tests knowledge of the section of the Traffic Rules on cargo transportation, specifically the requirements of clause 22.1, as well as understanding of the term "permissible maximum mass" from clause 1.10. The logic is simple: it is important not only how much cargo "fits," but whether the actual mass and axle load exceed the values specified in the technical characteristics of the specific vehicle (in the documents or on the manufacturer's plate).
The option that states a complete prohibition reflects the direct rule of the Traffic Rules: it is not allowed to exceed the technically permissible mass and/or axle load. The option about "permitted" contradicts clause 22.1, as it does not take into account the mandatory manufacturer’s restrictions. The wording about the possibility of movement along an agreed route also does not apply to this situation, since in this exam wording it is about exceeding the values specified in the technical characteristics of the vehicle, and the Traffic Rules set a direct restriction for this.
For the theoretical exam, it is important to remember: violation of the permissible mass or overloading of a separate axle can lead to damage to the chassis, deformation of components, loss of wheel traction with the road, and impaired handling. In practice, the driver must plan the loading so that the weight is distributed evenly, and heavy items are placed closer to the center of the vehicle, without creating dangerous overloading of the front or rear axle.
Clause 22.1
The mass of the cargo being transported and the axle load distribution must not exceed the values specified in the technical specifications of this vehicle.
Clause 1.10 (term "Permissible maximum mass")
Permissible maximum mass — the mass of the 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 the vehicles that make up the road train.
Thus, the correct answer is "Prohibited," given that according to the definition in the Traffic Rules, the cargo mass and axle load distribution cannot exceed the values established by the vehicle's technical specifications (clause 22.1).
When transporting cargo, the driver must focus not only on how much can “fit,” but also on the technical capabilities of the specific vehicle. The technical specifications (in particular, in the vehicle documents or on the manufacturer’s plate) define the permissible weight and permissible axle loads.
Clause 22.1 of the Traffic Rules of Ukraine establishes a direct requirement: the weight of the cargo and the distribution of the load on the axles must not exceed the values specified for this vehicle. That is, two criteria are important at once: the total weight of the cargo and how this weight is distributed on the front and rear (or other) axles. Even if the total weight seems to be within the norm, but the cargo is shifted backward or forward and overloads one axle, this is already a violation.
In practice, this looks as follows: if the driver loads the vehicle or trailer beyond the limits set by the manufacturer, the risk of failure of the running gear components increases, handling worsens, and the braking distance increases. Similarly, if heavy items are placed, for example, far in the rear of the trunk, the load on the rear axle may increase and the grip of the front wheels with the road may worsen, which directly affects safety.
Therefore, the correct answer is "Not allowed," since the Traffic Rules (clause 22.1) do not permit the transportation of cargo that exceeds the technically established weight and/or permissible axle load distribution for this vehicle.
