45.32. Which of the following indicators warns the driver of the vehicle about engine overheating?
UAЯкий із наведених індикаторів попереджає водія транспортного засобу про перегрів двигуна?
This is an exam question from the Traffic Rules of Ukraine concerning road safety through monitoring the technical condition of the vehicle while driving. Understanding the signals on the instrument panel helps to timely notice dangerous deviations in system operation and prevent breakdowns, accidents, or a forced stop in a hazardous location. For the theoretical exam, it is important not only to recognize the pictogram but also to realize that red indicators usually require the driver's immediate response.
The question tests knowledge of sections of the Traffic Rules that oblige the driver to monitor the serviceability of the vehicle: point 2.3 (the duty to control the technical condition while on the road) and the logic of the requirements of section 31 regarding the operation of vehicles and actions in case of malfunctions. Among the given indicators, it is the symbol with a red thermometer scale that belongs to the cooling system and warns of elevated temperature, that is, the risk of engine overheating. Other icons are easy to distinguish by their purpose: an exclamation mark in a circle signals the parking brake or a brake system malfunction, a fuel pump indicates a low fuel level, and a pictogram of a car with open doors notifies about unclosed doors.
The practical meaning of this topic is that correctly recognizing the “temperature” indicator allows you to timely reduce the load, stop safely, and check the cause (coolant level, fan operation, possible leak), and if necessary, act according to the Traffic Rules requirements regarding troubleshooting or move by the shortest route to a repair location with precautionary measures. Such knowledge directly affects engine longevity and safety, which is why similar exam questions regularly appear in the theoretical test.
Clause 2.3 (subclause "a")
To ensure road safety, the driver is obliged to: before departure, check and ensure the technical serviceability and completeness of the vehicle.
Brief application: the question about the engine overheating indicator checks whether the driver understands the signals of the technical condition monitoring instruments in order to timely detect a dangerous malfunction.
Clause 2.3 (subclause "b")
To ensure road safety, the driver is obliged to: be attentive, monitor the traffic situation, respond appropriately to its changes, monitor the correct placement and securing of cargo, the technical condition of the vehicle, and not be distracted from driving while on the road.
Brief application: monitoring indicators (in particular, coolant/engine temperature) is part of the duty to "monitor the technical condition of the vehicle."
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 their technical operation and the instructions of manufacturing enterprises.
Brief application: engine overheating is a sign of a dangerous deviation in the operation of the cooling system, which directly relates to the requirements for the technical condition of the vehicle.
Clause 31.4
The operation of vehicles is prohibited under the law if there are technical malfunctions and conditions specified by these Rules (the list is in subclauses 31.4.1–31.4.7).
Brief application: although "engine overheating" as an indicator is not named as a separate item in the list of 31.4, the logic of section 31 itself requires not to continue driving when the technical condition becomes dangerous or may lead to unit failure.
Clause 31.5
If technical malfunctions specified in clause 31.4 of these Rules occur on the road, the driver must take measures to eliminate them, and if this is not possible — proceed by the shortest route to a parking or repair location, observing safety precautions.
Brief application: recognizing the "red temperature" lamp/symbol is necessary to timely take measures (stop, eliminate the cause, proceed to the repair location with caution, or stop driving).
That is, the correct answer is "4.", given that according to the definition of the Traffic Rules, the driver is obliged to monitor the technical condition of the vehicle (clause 2.3) and act upon signs of a dangerous malfunction in accordance with the requirements of section 31, and the indicator in option 4 signals an increased temperature (overheating) in the engine cooling system.
While driving, the driver must constantly monitor the readings of instruments and indicator lights on the dashboard, as they warn about malfunctions or dangerous operating modes of the vehicle. One of these dangerous conditions is engine overheating, which is usually associated with excessive temperature of the coolant in the cooling system.
The engine overheating indicator is recognized by the symbol of a thermometer with a scale and is usually red in color. A red signal means that the temperature has exceeded the permissible limits and the engine is operating in a dangerous mode. This indicator specifically warns about a temperature problem, not about other vehicle systems.
To avoid confusion, it is important to distinguish this sign from other common indicators. The lamp with an exclamation mark in a circle relates to the braking system or the parking brake, the fuel pump icon indicates a low fuel level, and the pictogram of a car with open doors points to unclosed doors. None of these are related to engine temperature control.
Therefore, the correct answer is "4.", because it is the indicator with a red thermometer (temperature scale) that warns about increased temperature in the cooling system and engine overheating.
