48.74. By how much must the overall height of the cargo being transported exceed the height from the road surface (except for container carriers on routes established by Ukravtodor and authorized units of the National Police) for the transportation of the cargo to be carried out under special rules?
UAНаскільки повинен бути перевищений габарит вантажу, що перевозиться, за висотою від поверхні дороги (крім контейнеровозів на встановлених Укравтодором і уповноваженим підрозділам Національної поліції маршрутах), щоб перевезення вантажу здійснювалася за спеціальними правилами?
Question without image
This exam question from the Traffic Rules of Ukraine concerns road safety during cargo transportation and the control of vehicle dimensions. Excessive height of a road train or truck creates risks of collisions with bridges, overpasses, power lines, and other infrastructure elements, so the traffic rules set clear limits after which special requirements for organizing transportation apply.
The question tests knowledge of the section of the Traffic Rules related to cargo transportation, specifically clause 22.5 of the Traffic Rules of Ukraine regarding the movement of oversized and heavy vehicles. As a general rule, if the height of the vehicle with cargo from the road surface exceeds 4 meters, the transportation must be carried out under special rules (an exception is made only for container carriers on approved routes, where a different limit applies). This threshold is key for the theoretical exam, as it determines the point when the standard mode of movement changes to a special one.
The analysis of the answer options comes down to comparing them with the norm of clause 22.5: values of 3 m and 3.5 m do not correspond to the established height limit for the general case, while 4.5 m is excessive and may mislead, as if an excess up to 4.49 m does not require special conditions. In practice, this means that even a slight excess over 4 m (for example, 4.1 m) switches the transportation to the special rules mode, which is important to remember when preparing for the theoretical exam and in real trips.
Clause 22.5
Road transportation of dangerous goods, movement of vehicles and their combinations is carried out under special rules if any of their dimensions exceed the following: width — 2.6 m (for agricultural machinery moving outside populated areas, village, township, and district city roads — 3.75 m), height from the road surface — 4 m (for container carriers on routes established by Ukravtodor and the National Police — 4.35 m), length — 22 m (for route vehicles — 25 m), actual mass over 40 t (for container carriers — over 44 t, on routes established by Ukravtodor and the National Police for them — up to 46 t), axle load on a single axle — 11 t (for buses, trolleybuses — 11.5 t), double axles — 16 t, triple axles — 22 t (for container carriers, axle load on a single axle — 11 t, double axles — 18 t, triple axles — 24 t), or if the cargo extends more than 2 m beyond the rear dimension of the vehicle. Axles should be considered double or triple if the distance between them (adjacent) does not exceed 2.5 m. Movement of vehicles and their combinations with a load on a single axle over 11 t, double axles — more than 16 t, triple axles — more than 22 t or an actual mass of more than 40 t (for container carriers, axle load on a single axle — over 11 t, double axles — more than 18 t, triple axles — more than 24 t or an actual mass of more than 44 t, and on routes established by Ukravtodor and the National Police for them — more than 46 t) when transporting divisible goods by road is prohibited. Movement of vehicles with an axle load of more than 7 t or an actual mass of more than 24 t on local public roads is prohibited.
Explanation of application: within the scope of this question, it is specifically the maximum height from the road surface, after exceeding which transportation is carried out "under special rules," that is being checked. For the general case (except container carriers on specially established routes), this threshold is 4 m.
That is, the correct answer is "4 m," considering that according to the definition in the Traffic Rules, exceeding the height from the road surface of more than 4 m (as a general rule) transfers the transportation to the "under special rules" mode.
In this question, you need to determine the height limit after which the transportation of cargo is considered to exceed the permissible dimensions and therefore must be carried out according to special rules.
Clause 22.5 of the Traffic Rules of Ukraine sets specific maximum dimensions for a vehicle (including its cargo). For height, it is directly stated: if the height from the road surface exceeds 4 meters, such movement and transportation are carried out according to special rules. That is, what matters is exceeding the established limit of 4 m, not any deviation “by eye.”
For example, if a vehicle with cargo has a height of 4.1 m from the road surface, this is already more than 4 m, so the transportation falls under special rules. If the height is 3.95 m, then the limit is not exceeded and there is no reason to apply special rules specifically due to height.
The question separately specifies an exception for container carriers on specially established routes, where a different limit is allowed, but for all other cases the general rule from clause 22.5 applies.
Therefore, the correct answer is "4 m.", since according to clause 22.5 of the Traffic Rules, transportation is carried out under special rules when the height of the vehicle with cargo from the road surface exceeds 4 meters (excluding the special exception for container carriers on designated routes).
