12.16. While driving on the road, the driver encounters an obstacle to traffic. How should he act in this situation?
UAРухаючись по дорозі, водій виявив перешкоду для руху. Як він повинен вчинити в такій ситуації?
This is an exam question from the Traffic Rules of Ukraine about safety in unforeseen situations on the road: when a hazard or obstacle appears ahead (a pothole, debris, a parked or stopped vehicle, cargo on the roadway). It tests the basic skill of a driver to respond in a timely manner to changes in the road situation, since the correct reaction to an obstacle most often prevents accidents and is a key topic for the theoretical exam.
The content of the question checks the section of the Traffic Rules that concerns speed and the driver's actions in the event of danger, specifically point 12.3 of the Traffic Rules. The logic is simple: the driver must immediately reduce speed up to a complete stop or, if choosing to maneuver, perform a safe detour without risk to other road users (this also aligns with the general safety requirements for maneuvering). That is, priority is always given to speed control, and a detour is allowed only when it is guaranteed to be safe.
The analysis of the answer options shows why the correct formulation is about reducing speed up to a stop or a safe detour: it literally reproduces the requirement of point 12.3 and does not contain any conditional "half-measures." The option with a fixed reduction of 10 km/h is incorrect, because the traffic rules do not set such a "universal" number: sometimes it is necessary to brake much more intensively or come to a complete stop. The option without reducing speed is dangerous and contradicts the Traffic Rules of Ukraine, as it ignores the obligation for an immediate reaction to the obstacle and sharply increases the risk of collision.
Clause 12.3
In case of a danger to traffic or an obstacle that the driver can objectively detect, he must immediately take measures to reduce speed up to a complete stop of the vehicle or safely bypass the obstacle for other road users.
Clause 10.1
Before starting to move, changing lanes, or making any change in the direction of movement, the driver must make sure that it will be safe and will not create obstacles or danger to other road users.
Brief application: if to avoid an obstacle the driver chooses to bypass (maneuver), he is obliged to do so only after checking for safety, so as not to create danger/obstacle to others.
Clause 1.5
The actions or inaction of road users and other persons must not create danger or obstacles to traffic, threaten the life or health of citizens, or cause material damage.
Brief application: bypassing an obstacle is allowed only if such actions do not create danger or obstacles for other road users.
That is, the correct answer is "Reduce speed (up to stopping the vehicle) or, ensuring safety for other road users, bypass the obstacle," given that according to the definition of the Traffic Rules, when a danger/obstacle appears, the driver is obliged to immediately reduce speed up to a stop or make a safe bypass, not creating danger to others.
While driving, the driver constantly assesses the road situation. If an obstacle appears ahead (for example, debris, a pothole, a stopped vehicle, or cargo on the roadway), this automatically means that the driving conditions have changed and immediate action is required, rather than "continuing as before."
Clause 12.3 of the Traffic Rules of Ukraine establishes a clear algorithm: when a danger or obstacle arises that the driver could objectively detect, they are obliged to take action immediately. The first and most universal measure is to reduce speed, up to a complete stop. This provides time to assess the situation, shortens the braking distance, and reduces the risk of a collision.
If stopping in front of the obstacle is impractical or impossible, the Rules allow for a second course of action — to drive around it. However, driving around is permitted only if it is safe for other road users. That is, before making the maneuver, you must make sure that it does not create danger for oncoming traffic, pedestrians, cyclists, or those moving behind you, and only then change your direction of travel.
In practice, it looks like this: you notice an obstacle — immediately reduce your speed and prepare to stop. Then you assess: if the adjacent lane or oncoming lane is free and the maneuver will not create a hazard — drive around. If there are oncoming vehicles or insufficient visibility — it is safer to stop and wait for an opportunity to proceed.
Therefore, the correct answer is "Reduce speed (up to stopping the vehicle) or, ensuring the safety of other road users, drive around the obstacle," since clause 12.3 of the Traffic Rules obliges the driver, upon detecting an obstacle, to immediately reduce speed up to a stop or to drive around only if it is completely safe for other road users.
