56.4. What is the maximum permitted speed on motor roads for trucks with a maximum authorized mass of over 3.5 t with trailers?
UAЗ якою максимальною швидкістю дозволено рухатися по дорогах для автомобілів вантажним автомобілям з дозволеною максимальною масою понад 3,5 т з причепами?
This exam question from the Traffic Rules of Ukraine concerns the safe speed regime outside populated areas and the correct choice of maximum permitted speed depending on the type of road. For the theoretical exam, it is important to understand that speed is determined not “by eye,” but according to the standards of the Traffic Rules and road signs, since exceeding the speed limit for heavy vehicles with trailers significantly increases the braking distance and the risk of jackknifing the road train.
Section 12 of the Traffic Rules of Ukraine “Speed of movement” is being tested here, specifically clause 12.6 (subclause g), which sets limits for “other vehicles” depending on the type of road: 130 km/h on a motorway (sign 5.1), 110 km/h on a road with separate carriageways divided by a median strip, and 90 km/h on other roads. A truck with a permitted maximum mass over 3.5 t with a trailer is not singled out in clause 12.6 as a separate category with a reduced norm, so the general limit for “other vehicles” applies specifically to the expressway of the corresponding type (the logic applies to a road marked with sign 5.3 “Road for automobiles,” which indicates special traffic conditions according to section 27).
The analysis of the answer options helps avoid typical mistakes on the theoretical exam: 80 km/h is usually associated with passenger cars with trailers and motorcycles (other subclauses of 12.6), so it does not fit here; 90 km/h corresponds to “other roads” without a median strip, not to an expressway with separate carriageways; 130 km/h is only possible on a motorway (sign 5.1), so this is an excessive option for this type of road. The correct limit follows from subclause 12.6 g: 110 km/h as the standard for a road with a median strip, which is exactly what is being tested in this exam question on the traffic rules.
Clause 12.6 (subclause g)
Outside populated areas on all roads and on roads passing through populated areas marked with sign 5.51 "Beginning of a populated area", movement is allowed at the following speeds: e) for other vehicles: on a motorway marked with road sign 5.1 "Motorway" — 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.
Explanation of application: trucks with a permitted maximum mass of over 3.5 t with trailers are not singled out in subclauses "a"—"v" of clause 12.6 as a separate category with a reduced limit, therefore they fall under "other vehicles", for which the limit on a road with a median strip is set at 110 km/h.
Clause 33.5.1 — 33 "Road signs", 5 "Informational and direction signs", sign 5.3 "Road for automobiles"
"Road for automobiles" — used to designate a road intended only for the movement of cars, buses, and motorcycles and on which special traffic conditions apply as provided in section 27 of these Rules (except for clause 27.3).
Explanation of application: the question concerns movement specifically on a "road for automobiles" (sign 5.3), for which, in the examination logic, the speed regime is applied as for a road with separate carriageways divided by a median strip (clause 12.6, subclause g) — 110 km/h.
Clause 1.10 (term "Truck")
Truck — a vehicle that, by its design and equipment, is intended for the transportation of goods.
Clause 1.10 (term "Permitted maximum mass")
Permitted maximum mass — the mass of the equipped vehicle with cargo, driver, and passengers, established by the technical specification of the vehicle as the maximum allowable.
Clause 1.10 (term "Trailer")
Trailer — a vehicle intended to move only in conjunction with another vehicle. This category also includes semi-trailers and dolly trailers.
Thus, the correct answer is "110 km/h", given that according to the definition of the Traffic Rules, a truck with a trailer (over 3.5 t) belongs to "other vehicles" in clause 12.6 (subclause g), and for a road with separate carriageways divided by a median strip (the logic applied to a road marked with sign 5.3), the limit is set at no more than 110 km/h.
The question refers to a truck with a permitted maximum mass exceeding 3.5 tons that is traveling with a trailer. That is, this is a road train: a truck (a vehicle designed for the transportation of goods) coupled with a trailer (which moves only together with another vehicle). For choosing the correct speed, the key factor is not the mere presence of a trailer, but rather which type of road is meant and which speed limit category applies to “other vehicles.”
Clause 12.6 of the Traffic Rules determines the maximum speeds outside populated areas depending on the type of road. Subclause 12.6 (g) states that for “other vehicles” (i.e., those not included in special categories such as buses, mopeds, vehicles with 60/70/80/90 km/h restrictions), the following limits are set: 130 km/h on motorways, 110 km/h on roads with a dividing strip (separate carriageways in different directions), and 90 km/h on other automobile roads.
The road referred to in this question corresponds to the mode of an expressway, which under the conditions of the task is equated to a road with separate carriageways divided by a median strip. It is for this type of road that subclause 12.6 (g) sets the upper limit at 110 km/h. At the same time, trucks with a permitted maximum mass of more than 3.5 tons with trailers in this case do not have a separate, lower speed limit specifically due to their mass or the presence of a trailer, so the general rule for “other vehicles” on this type of road applies.
Therefore, the correct answer is "110 km/h," since according to clause 12.6 (g), on a road with a dividing strip, the maximum speed for other vehicles is 110 km/h, and a truck over 3.5 tons with a trailer falls under this rule.
