This exam question from the Traffic Rules of Ukraine tests attentiveness to supplementary plates that specify the conditions for parking and stopping, as well as understanding how additional information on signs affects safety and comfort in populated areas. Such restrictions are often introduced in places where noise and exhaust fumes are undesirable, so knowledge of the traffic rules in this part is important both for the theoretical exam and for daily driving practice.
According to the content of the task, it refers to Section 33 of the Traffic Rules, specifically to supplementary plates for road signs: sign 7.7 "Parking with the engine off." It is used together with informational signs 5.42 "Parking place" or 5.43 "Parking zone" and establishes a specific condition: vehicles may only be left after the engine is turned off. This particular feature distinguishes the required plate from other similar options.
When choosing the correct plate, it is important to eliminate "similar in shape but different in meaning" options. Plates 1 and 2 belong to group 7.6 "Method of placing the vehicle for parking" and only indicate how exactly to position the car relative to the sidewalk or roadway, without introducing requirements regarding engine operation. Plates 4 and 5 from group 7.5 "Type of vehicle" specify which vehicles the sign applies to (by type or permitted maximum mass), but also do not regulate whether the engine may run during parking. Therefore, in this exam question, the only option that directly establishes the condition "only with the engine off" corresponds to plate 7.7.
Clause 33.7.7 — 33 "Road Signs", 7 "Plates to Road Signs", sign 7.7 "Parking with Engine Off"
Indicates that in a parking area designated by signs 5.42 "Parking Place" or 5.43 "Parking Zone", vehicles are allowed to be left only with the engine turned off. The plate is placed directly under the signs with which it is used.
Clause 33.5.42 — 33 "Road Signs", 5 "Information and Direction Signs", sign 5.42 "Parking Place"
Indicates a place where parking of vehicles is permitted.
Clause 33.5.43 — 33 "Road Signs", 5 "Information and Direction Signs", sign 5.43 "Parking Zone"
Indicates a zone where parking of vehicles is permitted.
That is, the correct answer is "Plate 3.", considering that according to the definition in the Traffic Rules, plate 7.7 directly establishes the parking condition: vehicles are allowed to be left only with the engine turned off.
When completing this task, you need to find the plate that does not regulate the method of parking the vehicle or the type of vehicle, but instead sets a specific condition for parking: the engine must be turned off.
Plates numbered 1 and 2 belong to the group "Method of parking the vehicle." They only indicate how exactly the car should be positioned relative to the sidewalk or the roadway (for example, parallel or partially on the sidewalk). They do not set any requirements regarding the operation of the engine.
Plates numbered 4 and 5 belong to the group "Type of vehicle." Their purpose is different: to clarify which vehicles the sign applies to (for example, only trucks or only a certain category by weight). This is also not related to whether the engine is running or not.
The only plate that directly introduces the condition "parking only with the engine off" is provided in section 33 of the Traffic Rules as plate 7.7. It is used together with signs that indicate a parking place or zone (for example, "Parking place" or "Parking zone") and means: leaving the vehicle is allowed only after turning off the engine. In practice, this is a typical requirement for places where prolonged engine operation is prohibited due to noise or exhaust fumes.
Therefore, the correct answer is "Plate 3," because it (7.7) specifically sets the parking condition: vehicles may only be left with the engine turned off, that is, not running.
