This exam question from the Traffic Rules of Ukraine concerns fire safety on route vehicles and the proper equipping of a trolleybus with fire extinguishing means. For passenger transport, the risks are higher due to the large number of people in the cabin and the presence of electrical equipment, so the traffic rules and related regulations require not just the "presence" of a fire extinguisher, but actual readiness to quickly use it in an emergency situation.
The question checks the section of the Traffic Rules on the technical condition and equipment of vehicles (in particular, the requirements of points 31.1 and 31.4.7), as well as the understanding that a trolleybus belongs to route vehicles (a term from point 1.10), for which increased safety requirements apply. It is important to remember: the specific quantity and placement are determined not "by eye," but by relevant equipment standards, and if the manufacturer has not provided standard mounting locations, the fire extinguishers must still be securely fastened in accessible areas.
The analysis of answer options comes down to the logic of accessibility and duplication of response means. The solution with one fire extinguisher in the driver's cabin is insufficient for a trolleybus: in case of smoke, blocked passage, or fire in the passenger compartment, a single access point does not provide a quick response. The option with two fire extinguishers, but both in the cabin, is also practically weak: the passenger area remains without quick access, and a fire in the cabin could cut the driver off from the incident. Three fire extinguishers, including one in the "luggage compartment," do not correspond to typical standards for a trolleybus and indicate excessive or inappropriate equipment for this vehicle.
For the theoretical exam, it is important to remember the key principle: a trolleybus must have two fire extinguishers in different parts of the vehicle so that both the driver and passengers have quick access in case of fire. In practice, this means securely fastening one in the control area and the other in the passenger compartment, so that the fire extinguisher is not "searched for" and no seconds are lost, which could be crucial.
Clause 1.10 (term "Route vehicle")
Route vehicle — a public transport vehicle (bus, minibus, trolleybus, tram, taxi) that operates along a designated route and has specified stops for boarding (alighting) passengers.
This term clarifies that a trolleybus is classified as a route vehicle, for which enhanced requirements for equipment and passenger safety apply.
Clause 31.1
The technical condition of vehicles and their equipment must comply with the standards, rules, and regulations related to road safety and environmental protection.
This clause serves as the basis for applying special regulatory documents regarding equipment (in particular, the "Standards for equipping wheeled vehicles with fire extinguishers"), which establish the number and placement of fire extinguishers in a trolleybus.
Clause 31.4.7
It is prohibited to operate vehicles under the law if the following technical malfunctions or non-compliance with such requirements are present: the vehicle lacks a first aid kit, emergency stop sign or flashing red lamp, or a functioning fire extinguisher.
This clause directly tests knowledge about the mandatory presence of a functioning fire extinguisher(s) in the vehicle; the specific number and placement for a trolleybus are determined by the regulations referenced in clause 31.1.
Thus, the correct answer is "Two fire extinguishers, one of which must be secured in the driver's cab and the other in the passenger compartment," given that according to the definition in the Traffic Rules, the vehicle must be equipped with a functioning fire extinguisher(s), and the specific equipment and placement standards are established by the standards, rules, and regulations which the Traffic Rules require compliance with.
During the operation of a trolleybus, fire safety issues are addressed not "at will," but according to established equipment standards. A trolleybus carries passengers, has electrical equipment, and a large number of people in the cabin, so fire extinguishers must not only be present but also accessible for quick use.
The standards for equipping wheeled vehicles with fire extinguishers stipulate that a trolleybus must have at least two fire extinguishers. The logic is simple: one fire extinguisher may be inaccessible at the moment of ignition (for example, if fire or smoke blocks the approach), so two independent "access points" are needed in different parts of the vehicle.
If the design of the trolleybus does not provide standard mounting locations for fire extinguishers, they must still be securely fastened so that they do not move during travel and do not pose a danger to passengers. At the same time, the key practical requirement is the ability to quickly retrieve the fire extinguisher without searching and without unnecessary obstacles.
That is why one fire extinguisher is placed in the driver's cabin: the driver can instantly respond to a fire in the control area or electrical equipment. The second fire extinguisher must be in the passenger compartment, so it can be used near the source of ignition in the cabin or so that passengers/conductor can act if the driver is physically unable to quickly reach the necessary location.
Thus, the correct answer is "Two fire extinguishers, one of which must be secured in the driver's cabin and the other in the passenger compartment," since the equipment standards require two fire extinguishers for a trolleybus and their placement in different, accessible areas for quick response by the driver and passengers.
