This exam question from the Traffic Rules of Ukraine concerns road safety in the event of a technical malfunction while driving. For a motorcyclist, the speedometer is a key instrument for monitoring speed and complying with limits, and its failure increases the risk of violations and dangerous situations. That is why the traffic rules regulate how to act in order to minimize risks for yourself and other road users.
The question tests knowledge of the section of the Traffic Rules regarding the technical condition of vehicles and the procedure for the driver in case of malfunctions, specifically paragraphs 31.4.7 and 31.5. According to the requirements, operating a vehicle with a faulty speedometer is prohibited, but if the breakdown occurs on the road, the driver must first take measures to fix it on the spot. If this is not possible, it is allowed to proceed only by the shortest route to a parking or repair location with precautionary measures, including turning on the hazard warning lights (or using the emergency stop sign if hazard lights are not available).
The analysis of answer options for the theoretical exam demonstrates the logic of the Traffic Rules: continuing the trip "as planned," even with caution, is not allowed because this malfunction is among those for which operation is prohibited. The option of completely stopping the movement is also not universally correct, since the rules allow limited travel to repair/parking so as not to create additional hazards by leaving the motorcycle on the road. The correct algorithm is "try to fix it—if not possible, proceed by the shortest route to repair with warning to others," and this is what needs to be remembered for this exam question.
Clause 31.4.7
The operation of vehicles is prohibited under the law if the following technical malfunctions and non-compliance with standard requirements are present: the speedometer does not work.
Clause 31.5
If any of the malfunctions specified in clause 31.4 of these Rules occur while driving, 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 and turning on the hazard warning lights, and if the vehicle is not equipped with hazard warning lights — placing an emergency stop sign at the rear of the vehicle.
Therefore, the correct answer is: "Try to fix the malfunction on the spot, and if this is not possible, proceed to the nearest parking or repair location, turning on the hazard warning lights or placing an emergency stop sign at the rear of the vehicle," given that according to the Traffic Rules, operation with a faulty speedometer is prohibited, but if such a malfunction occurs while driving, it is allowed to proceed by the shortest route to a parking/repair location using safety measures (hazard warning lights or emergency stop sign).
While driving, the speedometer on a motorcycle is an important instrument because it allows the driver to monitor speed and comply with established limits. When the speedometer suddenly stops working, this means the vehicle has a technical malfunction that may affect traffic safety.
According to paragraph 31.5 of the Traffic Rules, in case of a malfunction on the road, the driver must first take measures to fix it on the spot. In practice, this may mean checking for obvious causes that can be quickly and safely corrected without entering the traffic flow, such as checking the connector contact if accessible, or making sure the malfunction is not due to a simple break or disconnection that can be restored.
If it is not possible to fix the malfunction on the spot, the rules allow you to continue driving only for the purpose of reaching a parking or repair location, choosing the shortest and safest route. The logic here is simple: you cannot continue driving "as if nothing happened," but it is also dangerous to leave the motorcycle in the middle of the road, so limited movement is allowed to a place where the problem can be resolved.
So that other road users understand that your vehicle has a malfunction and is moving in a special mode, it is necessary to take precautionary measures: turn on the hazard warning lights, and if necessary to mark the motorcycle from behind, place an emergency stop sign. For example, if you are forced to drive more slowly or stop on the roadside for inspection, warning other drivers reduces the risk of a collision or dangerous approach.
Therefore, the correct answer is "Try to fix the malfunction on the spot, and if this is not possible, proceed to a parking or repair location, turning on the hazard warning lights or placing an emergency stop sign at the rear of the vehicle," since paragraph 31.5 of the Traffic Rules requires first attempting to fix the malfunction, and if this is not possible, only allows limited movement to a parking or repair location with mandatory warning measures for other road users.
