Clause 2.3 (subclause "a")

The driver is obliged: "a) before driving, to check and ensure the proper technical condition and completeness of the vehicle, the correct placement and fastening of the cargo; ..."

Clause 31.1

"The technical condition of vehicles and their equipment must comply with the requirements of standards related to road safety and environmental protection, as well as the rules of technical operation, manufacturers' instructions, and other regulatory and technical documentation."

Application of the above clauses to the exam question

The cited traffic rules directly require maintaining the vehicle in proper technical condition and in accordance with the rules of technical operation. That is why the exam question checks the understanding that current repair is a way to restore the operability of the vehicle by eliminating specific malfunctions (through repair or replacement of individual elements).

Note on the term "current repair" in the Traffic Rules

The Traffic Rules of Ukraine do not establish the term or a separate definition of "current repair (of a trolleybus)"; this concept belongs to the sphere of technical operation rules/instructions and maintenance and repair standards, which the Traffic Rules refer to through the requirement to ensure proper technical condition.

That is, the correct answer is "To restore operability by replacing or repairing individual faulty parts, units, or assemblies," given that according to the Traffic Rules, the driver must ensure the proper technical condition of the vehicle and its compliance with the rules of technical operation, and current repair is precisely aimed at restoring operability through the repair/replacement of individual faulty components.

Current repair of a trolleybus is needed when the vehicle as a whole retains its structural integrity, but individual components are already malfunctioning or have failed. In such a situation, the main task of the repair is not to “rebuild” the trolleybus, but to quickly and technically correctly restore it to working condition.

The logic of the term “current” lies in the fact that it addresses specific, localized malfunctions that occur during operation. This may include replacing worn brake pads, repairing the door mechanism, restoring the operation of lighting devices, replacing a bearing, repairing a specific element of the electrical equipment, and so on. That is, the repair is aimed at a particular part, unit, or assembly that is not performing its function.

An important feature of current repair: it does not involve large-scale disassembly of the main structures or complete restoration of the entire vehicle’s resource. Its purpose is practical and clear — to eliminate specific malfunctions so that the trolleybus can once again operate safely and reliably on the route.

Therefore, the correct answer is “To restore operability by replacing or repairing individual faulty parts, units, or assemblies,” since current repair is aimed at eliminating localized malfunctions by replacing or restoring specific elements to return the trolleybus to working condition.
