This exam question from the Traffic Rules of Ukraine concerns road safety after a traffic accident and the proper way to warn other road users about danger. In real situations, hazard warning lights may be noticed too late (at a turn, on an incline, in fog, or at night), so the traffic rules require additional marking of the accident site to ensure that approaching drivers have enough time to react in advance and avoid a secondary collision.
The question tests knowledge of Section 9 "Warning Signals" (clauses 9.10 a and 9.11), as well as the driver's duties in the event of an accident under clause 2.10. The logic of the rule is simple: in the event of an accident, it is necessary not only to turn on the hazard warning lights but also to place an emergency stop sign or a flashing red light at a distance that ensures road safety. That is why the correct answer is the option where the requirement always applies, regardless of the location of the incident or the extent of the damage.
Analysis of the options shows typical mistakes made in the theoretical exam: the statement "only if there are injured persons" narrows the requirements of the Traffic Rules of Ukraine, although the sign is placed to warn other drivers about the danger, not depending on the presence of injuries. The option "only outside populated areas" is also incorrect, because clause 9.11 establishes the obligation in the event of an accident without reference to the territory; in the city, the risk of a collision or secondary accident is just as high. Knowledge of this topic helps you act correctly at the scene of an accident and avoid additional dangerous situations on the road.
Clause 2.10 (driver's duties in case of involvement in a traffic accident)
In case of involvement in a road traffic accident, the driver is obliged to: ... turn on the hazard warning lights and set up the emergency stop sign in accordance with the requirements of these Rules.
Clause 9.10 (Section 9 "Warning Signals"), subclause "a"
The hazard warning lights must be turned on: a) in the event of a road traffic accident.
Clause 9.11 (Section 9 "Warning Signals" — setting up the emergency stop sign)
In case of a forced stop, as well as in the event of a road traffic accident, the driver must place the emergency stop sign or a flashing red lantern at a distance that ensures road safety.
Clause 1.10 (term "Emergency stop sign")
Emergency stop sign — a device in the form of an equilateral red triangle with a reflective surface (or a flashing red lantern), which is placed on the vehicle or on the road in order to warn other road users of danger.
Thus, the correct answer is "Mandatory in any case.", given that according to the definition of the Traffic Rules, in the event of a traffic accident, the driver is obliged to turn on the hazard warning lights and must set up the emergency stop sign (or a flashing red lantern).
After a road traffic accident, the driver is required not only to stop but also to immediately make the scene noticeable to other road users. The goal is simple: to warn other drivers in advance so that they have time to reduce speed, change lanes, or stop without the risk of another collision.
Clause 9.10 (a) of the Rules stipulates that in the event of an accident, the hazard warning lights must be switched on and, in addition, the vehicle must be marked with an emergency stop sign (or a flashing red lantern). This should be done at such a distance that, under specific conditions, approaching drivers can react safely. For example, on a curve, after a rise, in fog, or at night, the hazard warning lights alone may not be enough: they may be noticed too late, whereas the sign provides an earlier warning.
It is important that the requirement to set up the sign does not depend on the "seriousness" of the accident, the location of the incident, or whether the car is obstructing traffic. Even if the damage is minor or the car is parked by the roadside, the obligation to warn other drivers remains, because the risk of danger still exists.
Therefore, the correct answer is "Mandatory in any case," since in the event of an accident, according to clause 9.10 (a), along with switching on the hazard warning lights, the driver must also set up the emergency stop sign (or flashing red lantern) to ensure road safety.
