56.5. What is the maximum permitted speed for passenger cars with trailers on roads passing through populated areas marked with this road sign?
UAЗ якою максимальною швидкістю дозволено рух легкових автомобілів із причепами на дорогах, що проходять через населені пункти, позначені таким дорожнім знаком?
This exam question from the Traffic Rules of Ukraine tests knowledge of speed limits and the ability to correctly apply traffic regulations depending on road signs. The topic is directly related to safety: exceeding the speed limit in built-up areas with heavy traffic significantly increases the risk of accidents, especially for cars with trailers, which have a longer braking distance and poorer maneuverability.
The focus is on sign 5.51 "Beginning of a populated area," which indicates a populated area, but on the road where it is installed, the typical "urban" traffic requirements (in particular, the standard 50 km/h limit) do not apply. That is why, to determine the permitted speed, you need to refer to the section of the Traffic Rules on speed, specifically to clause 12.6, which directly sets limits for driving outside populated areas and on roads through populated areas marked with sign 5.51. Within this clause, a limit of 80 km/h is set for passenger cars with trailers, which is the correct answer for the theoretical exam.
Why other options are not suitable: 50 km/h is typical for an ordinary populated area with sign 5.45, but not for the regime set by 5.51; 60 km/h in clause 12.6 applies to other categories (for example, mopeds and trucks carrying people in the cargo area), not to passenger cars with trailers; 70 km/h applies to drivers with less than 2 years of experience, i.e., this is a different basis for restriction; 90 km/h in the same clause applies to buses (except minibuses), so for a passenger car with a trailer, such a speed would be excessive. In practice, this knowledge helps not to confuse "built-up area" with the "populated area regime" and to correctly choose the speed according to the sign and clause 12.6 of the Traffic Rules of Ukraine.
Clause 12.6
Outside populated areas on all roads and on roads passing through populated areas marked with sign 5.51 "Beginning of a populated area", it is allowed to drive at the following speeds: a) buses (minibuses) carrying organized groups of children, passenger cars with trailers, and motorcycles — no more than 80 km/h; b) vehicles driven by drivers with less than 2 years of experience — no more than 70 km/h; c) trucks carrying people in the cargo bed, and mopeds — no more than 60 km/h; d) buses (except minibuses) — no more than 90 km/h; e) other vehicles: on a motorway marked with road sign 5.1 — no more than 130 km/h, on a road with separate carriageways divided by a median strip — no more than 110 km/h, on other roads — no more than 90 km/h.
This clause directly establishes that for passenger cars with trailers on roads passing through populated areas marked with sign 5.51, the maximum speed is 80 km/h.
Clause 33.5.51 — 33 "Road signs", 5 "Informational and direction signs", sign 5.51 "Beginning of a populated area"
Sign 5.51 "Beginning of a populated area" is used to indicate the beginning of a populated area where, on the road where this sign is installed, the requirements of these Rules that define the procedure for movement in populated areas do not apply. The sign is installed at the actual boundary of the development adjacent to the road.
This definition is necessary to correctly attribute a section of the road to the traffic regime to which clause 12.6 directly applies (that is, as a "road passing through a populated area marked with sign 5.51").
Thus, the correct answer is "80 km/h", given that according to the definition of the Traffic Rules for passenger cars with trailers on roads through populated areas marked with sign 5.51, clause 12.6 sets a speed limit of no more than 80 km/h.
The image shows sign 5.51 "Beginning of a populated area." Its peculiarity is that it designates a populated area, but the traffic rules that usually apply within populated areas (in particular, the standard 50 km/h limit) do not apply on this section. That is, the road formally passes through a built-up area, but in terms of speed regime, it is equated to driving outside a populated area.
Next, it is necessary to refer to paragraph 12.6 of the Traffic Rules of Ukraine, which sets speed limits outside populated areas, as well as on roads passing through populated areas marked specifically with sign 5.51. This paragraph separately specifies that for passenger cars with a trailer, the maximum permitted speed is 80 km/h.
Therefore, the correct answer is "80 km/h," since on a road within a populated area marked with sign 5.51, the speed norms as outside a populated area apply, and for a passenger car with a trailer, paragraph 12.6 sets a limit of 80 km/h.
