This is an exam question from the Traffic Rules of Ukraine concerning the safety of transporting passengers on two-wheeled vehicles. On a motorcycle or moped, a child is not protected by a body and cannot be secured with seat belts, so the traffic rules set clear restrictions to reduce the risk of falling and injury during braking, maneuvers, or on uneven roads.
The question tests knowledge of Section 21 "Passenger Transportation," specifically clause 21.11 (b) of the Traffic Rules. The essence of the rule is as follows: it is prohibited to transport on the rear seat of a motorcycle or moped children who do not meet the minimum height threshold, as it is more difficult for them to hold on securely and use the standard supports. That is why the correct option in the theoretical exam is the condition that a child may be transported on the back only when they have sufficient height (the exam database uses a threshold of 150 cm).
The analysis of the answer options comes down to a simple rule: the option about 150 cm meets the requirements of the Traffic Rules and safety logic, because a lower height means a direct prohibition on transportation on the rear seat of a motorcycle/moped. The option about a height less than 145 cm is incorrect, as it lowers the established limit. The option about reaching the age of 12 is also not suitable for this wording: in this exam question, the criterion is specifically height, not age, so you should focus on the minimum height defined by the rules.
Clause 21.11 b) (Section 21 "Carriage of Passengers")
It is prohibited to transport: children whose height is less than 150 cm — on the rear seat of a motorcycle or moped (as well as in vehicles equipped with seat belts, without using special devices that allow the child to be fastened with the seat belts provided by the design of the vehicle; on the front seat of a passenger car — without using the aforementioned special devices).
Explanation of application: from this prohibition follows the condition for permission — a child may be transported on the rear seat of a motorcycle/moped only if their height is not less than the established threshold (150 cm).
Clause 1.10 (term "Moped")
Moped — a two-wheeled vehicle with an engine capacity of up to 50 cc or an electric motor with a power of up to 4 kW.
Clause 1.10 (term "Motorcycle")
Motorcycle — a two-wheeled motor vehicle with or without a sidecar, with an engine capacity of 50 cc or more. Motor scooters, motorized wheelchairs, tricycles, and other motor vehicles with a maximum permitted mass not exceeding 400 kg are equated to motorcycles.
Thus, the correct answer is "If the child's height is 150 cm or more," given that according to the definition in the Traffic Rules, clause 21.11 b) directly prohibits transporting children whose height is less than 150 cm on the rear seat of a motorcycle or moped.
When transporting passengers on two-wheeled vehicles, increased safety requirements apply, since motorcycles and mopeds do not have a body, seat belts, or the ability to securely fasten a small child with standard means. Therefore, the Traffic Rules directly restrict when a child can be transported on the rear seat of such vehicles at all.
Clause 21.11 (b) of the Traffic Rules establishes a prohibition on transporting children on the rear seat of a motorcycle or moped if their height is less than the established minimum. The logic of this rule is simple: a child of short stature cannot hold on steadily and safely, cannot reach the standard supports (footrests), and the risk of falling or injury during sudden maneuvers or braking increases significantly.
For the exam, it is important to consider the wording used in the current TSC MIA exam questions. They specify the criterion of exactly 150 cm: if the child's height is less, transportation on the rear seat of a motorcycle or moped is considered prohibited, and if it is 150 cm or more — allowed. For example, a child with a height of 140 cm cannot be transported on the rear seat, but a child with a height of 152 cm can, provided other motorcycle passenger safety requirements are met.
Therefore, the correct answer is "If the child's height is 150 cm or more," since according to the passenger transportation rules, it is prohibited to transport on the rear seat of a motorcycle or moped children who have not reached the established minimum height, and in the exam database this minimum is defined as 150 cm.
