45.19. Which of the following indicators becomes active when the car engine is started and remains lit until the seat belt is fastened?
UAЯкий з наведених індикаторів стає активним при запуску двигуна автомобіля та горить до тих пір, поки ремінь безпеки не буде пристебнутий?
This exam question focuses on the topic of road safety and driver discipline while operating a vehicle. In the context of the Traffic Rules of Ukraine, seat belts are considered basic passive safety devices, and their use directly affects the risk of injury in the event of an accident. That is why theoretical exams often include questions that test not only knowledge of traffic rules but also understanding of the logic behind warning signals on the instrument panel.
The question checks the section of the Traffic Rules regarding the duties and prohibitions for drivers and passengers, in particular the requirements of point 2.9 (c) and point 5.2 (b): the driver is prohibited from driving unbelted, and passengers must be belted while the vehicle is in motion if the car is equipped with seat belts. The corresponding indicator, after the engine is started, does not just perform a self-check but remains active until the seat belt is fastened; in many vehicles, this is additionally accompanied by an audible signal, which reinforces the reminder to comply with the rule.
The correct option is the one with the seat belt pictogram, as it is directly related to the driver's action and turns off after the cause is eliminated. The ABS indicator usually turns off after a short diagnostic check, and if it remains lit, it signals a system malfunction rather than a requirement to fasten the seat belt. The fuel pump icon indicates a low fuel level and the need to refuel, so it does not meet the condition of the indicator operating until the seat belt is fastened. Such understanding helps to confidently pass the theoretical exam and respond correctly to vehicle signals in real traffic.
Clause 2.9 (subclause "v")
The driver is prohibited from: operating a vehicle without fastening the seat belt, and transporting passengers who are not fastened with seat belts, if the vehicle is equipped with seat belts.
Brief explanation: the unfastened seat belt indicator on the dashboard is directly related to compliance with this prohibition — it reminds the driver of the need to fasten the seat belt before/during driving.
Clause 5.2 (subclause "b")
Passengers are required: while the vehicle is in motion and equipped with seat belts, to be fastened with seat belts.
Brief explanation: the question also indirectly checks the understanding that seat belts are mandatory not only for the driver but also for passengers (and in many cars, the indicator additionally signals this as well).
Therefore, the correct answer is "3.", given that according to the definition in the Traffic Rules, the driver (and passengers) must use seat belts, and the corresponding indicator on the dashboard is activated after the engine is started and remains lit until the belt is fastened.
After starting the engine, various indicator lights on the dashboard may briefly light up — this is the vehicle's system self-check. However, there is one indicator that does not just check itself, but stays on until the driver fulfills an obligation directly required by the Traffic Rules.
The Traffic Rules of Ukraine require that the driver and passengers use seat belts if the vehicle is equipped with them. That is why manufacturers install a reminder: when the ignition is turned on or the engine is started, a pictogram depicting a belted person is activated, and if the driver does not fasten the seat belt, the indicator continues to stay on (often additionally accompanied by an audible signal for a certain period). As soon as the seat belt is fastened, this reminder signal stops, because the reason for its activation has been eliminated.
The other options from the list do not meet the condition of the question. The ABS icon is not a reminder for the driver to take action — it usually goes out after self-diagnosis, and if it stays on for a long time, it indicates a system malfunction. The fuel pump symbol, on the other hand, lights up when the fuel level is low and is not related to starting the engine or the seat belt.
Therefore, the correct answer is "3.", because it is the seat belt indicator that turns on after the engine is started and stays on until the belt is fastened.
