This is an exam question from the Ukrainian Traffic Rules about road safety in the event of a sudden technical malfunction. A punctured tire sharply reduces controllability: the car may pull to one side, the risk of skidding increases, and sudden maneuvers or braking only heighten the danger for you and other road users. Therefore, the driver’s primary goal is to stabilize the trajectory, safely exit the traffic flow, and clearly warn others about the forced stop.
The question tests knowledge of sections of the Traffic Rules regarding the driver’s duties and actions during a forced stop: the definition of a “forced stop” (point 1.10), the requirement to stop on the shoulder or near the right edge of the roadway (point 15.1), as well as the obligation to turn on the hazard warning lights during a forced stop (point 9.9). This is a typical situation for the theoretical exam, where it is important to set priorities: first safety and warning, and only then troubleshooting.
The option involving pulling over to the shoulder and turning on the hazard warning lights is correct because it combines two key steps: removing the vehicle from the active lane and making it visible to others. The option of immediately changing the tire skips the critically important warning step (hazard lights), and also does not take into account that you must first fully ensure a safe stopping place and only then carry out repair actions. Inaction is the worst decision, as driving on a flat tire or stopping without proper marking creates an increased risk of an accident.
Clause 1.10 (term "Forced stop")
Forced stop — cessation of movement of a vehicle due to its technical malfunction or danger created by the load, the condition of the driver (passenger), or the appearance of an obstacle on the road.
Clause 1.10 (term "Shoulder")
Shoulder — an element of the road that adjoins directly to the outer edge of the carriageway at the same level, distinguished by the type of surface or marked by a horizontal road marking line.
Clause 2.3 (driver's duties)
The driver is obliged: to be attentive, monitor the traffic situation, respond appropriately to its changes, monitor the correct placement and securing of the load, the technical condition of the vehicle, and not to be distracted from driving this vehicle on the road.
A punctured tire is a technical malfunction that drastically changes the traffic situation and requires the driver to immediately ensure traffic safety (first of all — control the trajectory and further safe cessation of movement).
Clause 9.9
The hazard warning lights must be switched on: in case of a forced stop on the road.
A punctured tire by definition is a reason for a forced stop, so after leaving the carriageway, the hazard warning lights must be switched on without fail.
Clause 9.10
A warning triangle or a flashing red lamp must be placed in the event of a forced stop of a vehicle on the road.
This is the next action (after leaving/stopping and switching on the hazard lights) for additional marking of the vehicle.
Clause 15.1
Stopping and parking of vehicles must be carried out in specially designated places or on the shoulder, and in its absence — near the right edge of the carriageway (as close as possible to it).
A punctured tire requires just such a safe placement of the vehicle — to move onto the shoulder (if possible), so as not to create obstacles and danger on the carriageway.
That is, the correct answer is "Move onto the shoulder and switch on the hazard warning lights," given that a punctured tire is a forced stop (clause 1.10), the stop should be performed on the shoulder/near the right edge of the carriageway (clause 15.1), and in the event of a forced stop, the hazard warning lights must be switched on (clause 9.9).
A tire blowout while driving happens suddenly and immediately affects handling: the car may pull toward the side of the damaged wheel, and stability decreases. In such a situation, the main task of the driver in the first seconds is not to create additional danger with abrupt actions and to get the car out of the traffic flow to a safe place as quickly as possible.
First of all, you should maintain control over the direction of movement: hold the steering wheel firmly with both hands, avoid sharp turns, and do not brake suddenly. Sudden braking or maneuvering on a flat tire can cause skidding and uncontrolled shifting into another lane. The correct tactic is to gently reduce speed while keeping the car in its lane and choose a safe place to stop.
When the speed is reduced and the trajectory is stable, you need to pull over to the right onto the shoulder or another area away from active traffic. This is in line with the logic of the Traffic Rules: the driver must minimize obstruction to others and not stop where it creates danger or interferes with traffic. The shoulder allows you to stop without risk to the flow and without provoking collisions with vehicles moving behind.
Immediately after you begin to pull over/stop, you must turn on the hazard warning lights. According to the Traffic Rules, hazard lights are used, in particular, in the event of a forced stop or technical malfunction, to warn other road users of danger. This is especially important because a car with a flat tire may move unstably or stop in an unusual place for stopping.
Therefore, the correct answer is "Pull over to the shoulder and turn on the hazard warning lights," since in the event of a tire blowout, the primary task is to safely remove the car from the traffic flow and warn other drivers about the forced stop.
