Question without image
This exam question from the Traffic Rules of Ukraine concerns road safety and the proper functioning of external lighting devices. The logic of the rule is simple: when headlights or rear position lights are not working, the vehicle becomes poorly visible to other road users, and at night or in poor visibility conditions, the risk of an accident increases sharply. That is why the traffic rules establish not a 'recommendation,' but a direct prohibition on continuing to drive under certain conditions.
The question tests knowledge of the section of the Traffic Rules regarding the technical condition of vehicles and the prohibition of further movement in the presence of malfunctions, in particular, clause 31.6 (b). It states that driving is prohibited if, during hours of darkness or in conditions of insufficient visibility, the headlights or rear position lamps are not lit. For the theoretical exam, it is important to distinguish these concepts: hours of darkness last from sunset to sunrise, and insufficient visibility can occur even during the day (fog, heavy rain, snowfall, twilight), when the road is visible for less than 300 meters.
The analysis of the answer options comes down to the fact that the restriction applies not only in one of these conditions. The statement 'only in conditions of insufficient visibility' is incorrect, because the prohibition directly applies also to hours of darkness; likewise, 'only at night' is also incorrect, since the Traffic Rules of Ukraine separately mention insufficient visibility. In practice, this means that if the headlights or rear position lights fail, under the specified conditions you cannot even 'make it' to a parking lot or service station—you must stop, mark the vehicle with hazard warning lights and/or a warning triangle, and arrange for repairs on the spot or transport the vehicle in another way.
Clause 31.6 (prohibition of further movement in the presence of certain malfunctions)
"Further movement of vehicles is prohibited if: a) the service braking system or steering does not allow the driver to stop the vehicle or perform a maneuver while driving at minimum speed; b) at night or in conditions of insufficient visibility, the headlamp bulbs or rear position lamps are not lit; c) during rain or snowfall, the windshield wiper on the steering side does not work; d) the tractor-coupling device of a road train is damaged."
This clause checks the knowledge that if at night or in conditions of insufficient visibility the headlights or rear position lamps do not work, further movement is prohibited even "to the place of repair or parking."
Clause 1.10 (term "Night time")
"Night time — the part of the day from sunset to sunrise."
This definition is needed to determine when exactly the prohibition from clause 31.6 (subclause "b") regarding non-functioning headlights or rear position lamps applies.
Clause 1.10 (term "Insufficient visibility")
"Insufficient visibility — road visibility in the direction of movement less than 300 m in twilight, fog, rain, snowfall, etc."
This definition is needed to establish that the prohibition from clause 31.6 (subclause "b") applies not only at night, but also in conditions when visibility is insufficient (fog, rain, snowfall, etc.).
That is, the correct answer is "In both cases.", given that according to the definition of the Traffic Rules, clause 31.6 (b) directly prohibits further movement at night or in conditions of insufficient visibility if the headlamp bulbs or rear position lamps are not lit.
When the headlights or rear position lights suddenly fail while driving, the driver often thinks they can "make it" on their own at least to the nearest repair shop or parking lot. However, the Traffic Rules (PDR) provide for situations when this is not allowed, even if the distance seems small.
Clause 31.6 of the Traffic Rules of Ukraine explicitly prohibits further movement if, during hours of darkness or in conditions of insufficient visibility, the headlight or rear position lamp bulbs are not working. Hours of darkness are defined as the time from sunset to sunrise. Insufficient visibility means when the road in the direction of travel is visible for less than 300 meters (for example, at dusk, in fog, heavy rain, or snowfall). That is, the rules specify two separate circumstances, and in each of them, malfunctioning lighting devices make further movement illegal.
The logic of this prohibition is simple: without headlights, you are poorly visible to oncoming drivers, and without rear position lights — to those driving behind you. In darkness or fog, a car can become almost invisible, and even a short trip "to the service" sharply increases the risk of a rear-end collision or head-on crash. Therefore, under such conditions, continuing to drive under your own power is not allowed.
In practice, the correct action is to stop, mark the vehicle (turn on the hazard warning lights, and if necessary, place an emergency stop sign), and arrange to fix the malfunction on the spot or transport the vehicle by other means, rather than continue driving without proper lighting.
Therefore, the correct answer is "In both cases," since the Traffic Rules prohibit further movement with faulty headlights or rear position lights both during hours of darkness and in conditions of insufficient visibility, even to the place of repair or parking.
