UAВстановлений з якою із зображених табличок дорожній знак діє в усі робочі дні?
This exam question from the Traffic Rules of Ukraine tests attentiveness to the temporal effect of road signs, which directly impacts safety and the avoidance of fines. In real traffic, it is the additional plates that often determine when the requirement of a sign is mandatory: on weekdays, weekends, specific days of the week, or only at certain hours.
According to the traffic rules, this topic belongs to Section 33 "Road Signs," item 33.7 "Plates to Road Signs," specifically to the plates "Period of Effect." In the theoretical exam, you should not rely on guesswork, but clearly know the meaning of each plate: 7.4.2 establishes the effect of the sign during working days, that is, the requirement is valid on all weekdays, and does not apply on Saturdays, Sundays, and public holidays.
Other options in this group of plates do not meet the condition "on all working days": 7.4.1, on the contrary, limits the effect of the sign to weekends and public holidays; 7.4.3 specifies only particular days of the week (thus covering not all weekdays, but only some); 7.4.4 indicates only a time interval during the day regardless of whether it is a weekday or not; 7.4.7 combines a day of the week and hours, further narrowing the effect of the sign. That is why the correct choice for "all working days" is unequivocally determined by plate 7.4.2.
Clause 33.7 — 33 "Road signs", 7 "Plates to road signs" (general provisions)
Plates to road signs clarify or limit the effect of the signs and are used only together with those signs under (or on) which they are installed.
Clause 33.7 — 33 "Road signs", 7 "Plates to road signs", plate 7.4.1 "Period of validity"
Plate 7.4.1 "Period of validity" indicates that the sign applies on Saturdays, Sundays, and public holidays.
Clause 33.7 — 33 "Road signs", 7 "Plates to road signs", plate 7.4.2 "Period of validity"
Plate 7.4.2 "Period of validity" indicates that the sign applies on working days.
Clause 33.7 — 33 "Road signs", 7 "Plates to road signs", plate 7.4.3 "Period of validity"
Plate 7.4.3 "Period of validity" indicates the days of the week during which the sign applies.
Clause 33.7 — 33 "Road signs", 7 "Plates to road signs", plate 7.4.4 "Period of validity"
Plate 7.4.4 "Period of validity" indicates the time of day during which the sign applies.
Clause 33.7 — 33 "Road signs", 7 "Plates to road signs", plate 7.4.7 "Period of validity"
Plate 7.4.7 "Period of validity" indicates the days of the week and the time of day during which the sign applies.
That is, the correct answer is "With plate 2.", given that according to the definition in the Traffic Rules, plate 7.4.2 directly establishes the sign's effect during working days (unlike plates that specify weekends/holidays, individual days of the week, or only a time interval).
When a plate from section 33 of the Traffic Rules is installed under a road sign, it specifies on which days or at what time the requirement of this sign applies. Therefore, in such a question, you should not "guess," but determine which plate directly restricts the sign's effect specifically to working days.
According to the Traffic Rules, plate 7.4.2 indicates that the sign applies on working days. Its meaning is simple: if today is a regular working day (Monday–Friday, unless it is a holiday), then the sign's requirement is in effect; if it is Saturday, Sunday, or a holiday, then this requirement does not apply.
Other options do not meet the condition "on all working days." For example, a plate for weekends and holidays, on the contrary, excludes working days. A plate showing a time interval limits the sign's effect to certain hours, but does not emphasize working days specifically. Plates with specific days of the week (or a combination of day and hour) narrow the sign's effect only to certain days, not to all working days.
Thus, the correct answer is "With plate 2," since it is plate 7.4.2 according to the Traffic Rules that establishes the road sign's effect throughout all working days.
