Question without image
This exam question from the Traffic Rules of Ukraine concerns the legal participation of vehicles in road traffic and state registration, which is directly related to safety, owner responsibility, and the ability to identify the vehicle. Registration at the Ministry of Internal Affairs service center is required not "for formality," but so that the trailer has official status, correct documents, and can be legally used as part of a road train.
The question checks knowledge of the section of the Traffic Rules on state registration (point 30.1), as well as understanding of the terms "trailer" and "mechanical vehicle" from point 1.10. According to the Traffic Rules, trailer owners are required to register or re-register them with the authorized MIA body regardless of technical condition within 10 days from the moment of purchase, acquisition, customs clearance, or after modification or repair, if changes need to be made to the registration documents. This rule is fundamental for the theoretical exam.
The analysis of answer options in this theoretical exam comes down to a simple comparison with the Traffic Rules norm: the statement that registration is "not required" contradicts the direct requirement of point 30.1. The option tied to a weight of 750 kg is also misleading, because in the context of this exam question, the Traffic Rules of Ukraine establish the obligation to register trailers as a category, not based on the "up to/over 750 kg" criterion (this figure is more often mentioned in other topics, such as license categories or specific operational requirements).
Practically, this knowledge is important for every driver: after purchasing a used trailer, acquiring it for use on legal grounds, or importing it from abroad, it is necessary to promptly contact the MIA service center and complete the registration actions. This reduces the risk of fines and problems during document checks, and also helps to properly prepare for the "Vehicle Registration" sections in the traffic rules and the corresponding exam questions.
Clause 30.1
Owners of motor vehicles and trailers to them must register (re-register) them with the authorized body of the Ministry of Internal Affairs or carry out departmental registration if the law establishes the obligation to conduct such registration, regardless of their technical condition, within 10 days from the moment of purchase (receipt), customs clearance, or modification or repair, if it is necessary to make changes to the registration documents.
This clause directly establishes the obligation to register trailers (as well as motor vehicles) with the authorized body of the Ministry of Internal Affairs (service center of the Ministry of Internal Affairs) within the specified period.
Clause 1.10 (term "Trailer")
Trailer — a vehicle designed to move in a coupled state with a motor vehicle.
Application: the question concerns the "trailer" as a separate type of vehicle, to which the requirements of clause 30.1 apply.
Clause 1.10 (term "Motor vehicle")
Motor vehicle — a vehicle driven by an engine. This term applies to tractors, self-propelled machines and mechanisms, as well as trolleybuses and vehicles with an electric motor power of more than 3 kW.
Application: clause 30.1 establishes the obligation to register "motor vehicles and trailers to them", that is, for the combination of tractor unit (motor vehicle) + trailer.
Thus, the correct answer is "Registration is mandatory.", given that according to clause 30.1 of the Traffic Rules, owners of trailers are required to register (re-register) them with the authorized body of the Ministry of Internal Affairs within the established period.
In the Traffic Rules, a trailer is considered a separate vehicle as part of a road train, so for legal participation in road traffic, it must be officially registered by the state. That is why the registration requirement applies not only to cars but also to their trailers.
Clause 30.1 of the Traffic Rules establishes the obligation for owners of motor vehicles and trailers to register or re-register them with the authorized body of the Ministry of Internal Affairs. Importantly, this requirement applies regardless of the technical condition of the trailer: whether it is new, used, or after repair, if it is in your ownership and is to be used, it must be properly registered.
The period is also clearly defined: registration actions must be completed within 10 days from the moment of purchase (acquisition) of the trailer, its customs clearance, as well as after re-equipment or repair if this requires changes to the registration documents. For example, if you bought a used trailer under a sale and purchase agreement or brought it from abroad, you must meet this 10-day deadline and contact the service center for registration.
Therefore, the correct answer is "Registration is mandatory," since the Traffic Rules (clause 30.1) directly oblige the owner to register or re-register the trailer with the authorized body of the Ministry of Internal Affairs within the established period.
