This is an exam question from the Traffic Rules of Ukraine (PDR) concerning safety and traffic organization at intersections, where conflicts between traffic flows and pedestrians most often occur. The key idea is simple: even if the driver has a permissive signal or the right of way, they must not create an obstacle for other road users by blocking the passage. That is why the rule of "not entering if you cannot pass through" directly affects the throughput of intersections and reduces the risk of accidents.
For the theoretical exam, this question tests the section of the Traffic Rules regarding passing through intersections, specifically the requirements of clause 16.4 of the PDR of Ukraine. The rule prohibits entering any intersection (even on a green traffic light) if there is a traffic jam beyond it and the driver will be forced to stop directly at the intersection, blocking the movement of other vehicles and pedestrians. Additionally, it is important to understand the term "intersection" from clause 1.10 to correctly determine the boundaries of the area where this prohibition applies.
When analyzing the answer options, the speed limitation of the vehicle ahead by itself is not a reason for prohibiting entry: it is moving and clearing the intersection, so rule 16.4 does not apply here. The approach of a vehicle with an orange flashing beacon also does not automatically prohibit entering the intersection, since such a beacon mainly attracts attention and does not grant priority, unlike special signals of other colors. Instead, the situation with a traffic jam beyond the intersection fully corresponds to the requirement of clause 16.4, so this is the correct answer within the context of this exam question.
The practical meaning of the rule: when approaching an intersection, one should assess not only the traffic light signal or priority signs, but also the availability of free space beyond the intersection. If a driver enters and stops at the intersection, they "block" movement in cross directions, may block a pedestrian crossing, and provoke dangerous maneuvers. Therefore, the correct tactic according to the traffic rules is to stop before the stop line or before the intersection and wait until it is possible to pass through without stopping at the intersection itself.
Clause 16.4
It is prohibited to enter any intersection, including when the traffic light allows movement, if a traffic jam has formed that will force the driver to stop at the intersection, thereby creating an obstacle for the movement of other vehicles and pedestrians.
Application explanation: even with a permissive traffic light signal, the driver does not have the right to enter the intersection if there is no possibility to clear it ahead (beyond the intersection) and they will have to stop at the intersection, blocking the movement of other participants.
Clause 1.10 (term "Intersection")
An intersection is a place where roads cross, adjoin, or branch at the same level, bounded by imaginary lines between the beginnings of the curves of the edges of the carriageways of each road. The place where an exit from an adjacent territory adjoins the road is not considered an intersection.
Application explanation: this term clarifies exactly what is considered an intersection to which the prohibition established by clause 16.4 applies.
That is, the correct answer is: "If a traffic jam has formed beyond the intersection that will force the driver to stop at the intersection, and this will create an obstacle for the movement of other vehicles and pedestrians," given that according to the definition of the Traffic Rules, clause 16.4 directly prohibits entering an intersection when there is a traffic jam that will lead to stopping at the intersection and creating an obstacle for other road users.
When approaching an intersection, the driver must assess not only the traffic light signal or priority signs, but also the situation beyond the intersection. The Traffic Rules of Ukraine (paragraph 16.4) establish the rule: it is prohibited to enter an intersection if it is obvious that there is no space beyond it to continue driving.
The essence of this prohibition is as follows: even when you are allowed to proceed (for example, the green signal is on), you must not enter the intersection if there is a traffic jam ahead and you will be forced to stop directly at the intersection because of it. Stopping at the intersection "blocks" it: other vehicles cannot pass in their directions, and pedestrians may lose the opportunity to cross the road safely.
Practical example: you approach on green, but you see that there is a dense line of vehicles beyond the intersection and there is no free space. If you enter, your car will stop in the middle of the intersection, and when the signal for other directions turns green, they will not be able to pass, and pedestrians will have to go around your car or wait. It is precisely to prevent such situations that the rule requires you to remain before the stop line or before the intersection and wait until there is an opportunity to completely cross the intersection without stopping on it.
Therefore, the correct answer is "If there is a traffic jam beyond the intersection that will force the driver to stop at the intersection, and this will create an obstacle for the movement of other vehicles and pedestrians," since paragraph 16.4 of the Traffic Rules directly prohibits entering an intersection when there is no free space beyond it, so as not to block the movement of other participants.
