This exam question from the Traffic Rules of Ukraine concerns the safety of interacting with large vehicles in traffic and teaches how to assess risks when approaching, overtaking, or passing. On the road, trucks present additional hazards: larger dimensions, possible protruding cargo, limited visibility due to "blind spots," and the effect of air currents, which can "push" or "pull" lighter vehicles. That is why choosing the correct lateral gap is critically important to prevent contact and loss of stability.
In essence, this question tests the section of the Traffic Rules regarding distance and interval, specifically the requirement of point 13.1: the driver must maintain a safe distance and a safe interval, taking into account speed, road conditions, the state of the vehicle, and the characteristics of the cargo. In the context of the theoretical exam, it is important to understand that a "safe interval" is not a fixed value: when approaching a truck, it usually needs to be increased, as it requires more space to maneuver, and the truck driver may not see you nearby.
The "Yes" option aligns with the logic of the Traffic Rules: in the presence of additional risk factors, the driver should choose a larger lateral interval to actually ensure safety. The "No" option is incorrect, as it ignores the requirement of point 13.1 to adapt the interval to traffic conditions and the characteristics of the vehicle/cargo; in practice, this increases the risk of dangerous proximity due to air currents, unpredictable truck movements, or its limited visibility.
Clause 13.1
The driver, depending on the speed of movement, road conditions, the characteristics of the cargo being transported, and the condition of the vehicle, must maintain a safe distance and a safe interval.
Explanation of application: when approaching a truck (which has larger dimensions, possible protruding cargo, air flows, etc.), the driver is required to choose such a lateral interval that will be safe under these conditions; in practice, this means the need to increase the lateral interval.
Clause 1.10 (term "Safe interval")
Safe interval — the distance between the sides of moving vehicles, or between a vehicle and other objects, which ensures road safety.
Explanation of application: since the interval must ensure safety, when approaching a larger vehicle (a truck), the driver must choose a greater lateral gap if it is necessary for safety.
That is, the correct answer is "Yes.", given that according to the definition in the Traffic Rules, the driver is required to maintain a safe interval taking into account speed, road conditions, and the characteristics of the cargo/vehicle (clause 13.1, term clause 1.10).
When approaching a truck, it is important to assess in advance that a vehicle of significantly larger size and mass is moving next to you. Any deviation from its trajectory, even a minor one, takes up more space on the road than a passenger car. Therefore, the usual lateral gap that seems sufficient next to a car may turn out to be too small near a truck.
Clause 13.1 of the Traffic Rules obliges the driver, depending on speed, traffic conditions, the state of the vehicle, and the specifics of the cargo, to maintain a safe distance and a safe interval. A truck is precisely the case when the driving conditions objectively require a larger interval: a wider body, possible protruding cargo elements, and the truck's need for a greater "reserve" of space for maneuvering.
It is also necessary to take into account the truck driver's limited visibility. Due to larger "blind spots," the driver may not see a passenger car nearby, especially if you are approaching from the side while overtaking or passing. An increased lateral interval reduces the risk of dangerous proximity if the truck begins to move towards you, avoids an obstacle, or performs another maneuver.
At speed, the air flows from large vehicles also have a noticeable effect: near a truck, there may be gusts or your car may be "pulled" towards it. If the interval is small to begin with, these phenomena can further reduce the distance between vehicles without your intention, creating a risk of contact or loss of stability.
Therefore, the correct answer is "Yes," because according to clause 13.1 of the Traffic Rules, when approaching a truck, you must ensure a safe lateral interval taking into account its dimensions, possible maneuvers, blind spots, and the influence of air flows.
