9.6. In which cases is it necessary to switch on the hazard warning lights and place a warning triangle or a flashing red light at a distance from the vehicle to indicate the vehicle?
UAУ яких випадках для позначення транспортного засобу потрібно увімкнути аварійну сигналізацію і встановити знак аварійної зупинки або миготливий червоний ліхтар на відстані від транспортного засобу?
This exam question from the Traffic Rules of Ukraine tests knowledge of how to properly mark a vehicle in hazardous situations to warn other road users and reduce the risk of a secondary accident. According to the traffic rules, hazard warning lights are not always sufficient: in certain cases, the driver is additionally required to place a warning triangle or a flashing red lantern at a safe distance so that the warning is visible in advance.
In terms of content, this question belongs to the section on warning signals and the use of hazard warning lights (points 9.9 and 9.10 of the Traffic Rules). It directly focuses on the situations from point 9.10, when, together with the hazard lights, it is mandatory to set up a sign or lantern: after a traffic accident and during a forced stop in a place with limited visibility (less than 100 m in at least one direction). That is why the correct answer options combine two conditions: a traffic accident and a forced stop where drivers may see the obstacle too late.
Analyzing the answers helps avoid common mistakes on the theoretical exam. The option about a traffic accident is correct because after an accident, the car often becomes an obstacle and needs to be marked not only with flashing lights but also with a sign/lantern placed at a distance. The option about boarding/alighting organized groups of children relates to turning on the hazard lights according to point 9.9, but by itself is not a reason to necessarily set up a sign at a distance, as specifically required by point 9.10. The option about a forced stop in poor visibility conditions is also correct, since a sign or lantern is needed so that drivers have time to react, change speed, and trajectory.
It is practically important to remember the placement distance: the warning triangle or flashing red lantern should be placed so as to ensure safety, but not closer than 20 m in populated areas and 40 m outside them. Understanding this topic from the traffic rules helps not only to answer the exam question correctly, but also to act safely in real critical situations on the road.
Clause 9.9
“The hazard warning lights must be switched on: a) in case of a forced stop on the road; b) in case of stopping at the request of a police officer or as a result of the driver being blinded by headlights; c) on a motor vehicle moving with technical malfunctions, if such movement is not prohibited by these Rules; d) on a motor vehicle being towed; e) on a motor vehicle marked with the identification sign ‘Children’ that is transporting an organized group of children, during their boarding or disembarking; f) on all motor vehicles in a convoy during their stop on the road; g) in the event of a road traffic accident (RTA).”
This clause specifies that the hazard warning lights must be switched on, in particular, in the event of an RTA and in the case of a forced stop on the road, but the specific requirement to additionally place a warning triangle/flashing red lantern “at a distance” is detailed in clause 9.10.
Clause 9.10 a), b)
“Together with switching on the hazard warning lights, a warning triangle or a flashing red lantern must be placed at a distance that ensures road safety, but not closer than 20 m from the vehicle in populated areas and 40 m outside them, in the event of: a) a road traffic accident (RTA); b) a forced stop in places with limited road visibility of less than 100 m in at least one direction.”
This clause directly establishes the specific cases when, to indicate the vehicle, it is necessary not only to switch on the hazard warning lights, but also to obligatorily place a warning triangle (or flashing red lantern) at the specified distance.
That is, the correct answer is “Answers 1 and 3.”, given that according to the definition of the Traffic Rules, a warning triangle (or flashing red lantern) together with switching on the hazard warning lights is placed at a distance in the event of an RTA and in the event of a forced stop in a place with limited visibility of less than 100 m in at least one direction.
In this question, it is important to distinguish between two levels of action: simply turning on the hazard warning lights and, in addition to this, placing the emergency stop sign (or a flashing red lantern) at a certain distance. In every situation where the hazard lights are used, it is not always necessary to also place the sign — this is done only in cases where the vehicle needs to be specially marked for other road users due to increased danger.
Clause 9.10 of the Traffic Rules directly specifies the cases when, together with turning on the hazard warning lights, it is mandatory to install the emergency stop sign or a flashing red lantern at a distance that ensures safety, but not closer than 20 m in a populated area and 40 m outside of it. The first case is when a road traffic accident has occurred. The logic is simple: after an accident, the vehicle may create an obstacle or danger, so the driver is obliged not only to warn with flashing lights, but also to “bring out” the warning in advance onto the road with a sign/lantern.
The second case from clause 9.10 is a forced stop in a place where the visibility of the road is limited in at least one direction to less than 100 meters. For example, a breakdown occurred just after a turn, on an ascent, or in a place where the view is blocked by trees or buildings. In such a situation, the hazard lights alone may be noticed too late, so the sign (or lantern) is placed at a distance so that approaching drivers have time to react in advance and safely change their trajectory or speed.
Therefore, the correct answer is “Answers 1 and 3.”, because the emergency stop sign (or flashing red lantern) together with the hazard warning lights is mandatory precisely in the event of an accident and in the event of a forced stop in a place with limited visibility of less than 100 m.
