This is an exam question from the Ukrainian Traffic Rules concerning the safety of performing maneuvers, specifically a U-turn, which always involves crossing the paths of other vehicles and requires sufficient space and visibility. The theoretical test often includes situations where a U-turn may seem "convenient," but in reality, it creates an increased risk of accidents due to limited width, the impossibility of bypassing, and poor visibility.
The question checks knowledge of the section of the traffic rules on maneuvering, namely paragraph 10.7 of the Traffic Rules of Ukraine (subparagraphs b), v)), which directly define the places where a U-turn is prohibited. The logic of the prohibition is simple: in tunnels, the maneuver is dangerous due to limited space, lighting, and visibility; on bridges, overpasses, and viaducts, the danger increases due to the narrow roadway, barriers, and the high cost of mistakes; the same prohibition applies under these structures, where dimensions, visibility, and the ability to safely complete the maneuver are often limited.
If you analyze the answer options, individual points about tunnels and about bridges/overpasses/viaducts reflect only part of the rule, since the Traffic Rules prohibit U-turns both on the structures themselves and under them, as well as in tunnels. That is why the correct option is the one that combines all the listed places: it fully complies with the requirements of paragraph 10.7 and helps to remember that in "restricted" engineering structures and enclosed sections of the road, U-turns are not allowed regardless of traffic intensity.
Clause 10.7 (subclause "a")
U-turns are prohibited: a) at railway crossings.
Application: at any railway crossing, making a U-turn is not allowed regardless of traffic conditions and the presence/absence of a barrier.
Clause 10.7 (subclause "b")
U-turns are prohibited: b) on bridges, overpasses, flyovers, and under them.
Application: the prohibition applies both directly on the structure (bridge/overpass/flyover) and underneath it.
Clause 10.7 (subclause "c")
U-turns are prohibited: c) in tunnels.
Application: within a tunnel, U-turns are completely prohibited due to the increased danger of the maneuver in a confined space.
Therefore, the correct answer is "Answers 1, 2, and 3," considering that according to the definition of the Traffic Rules, U-turns are expressly prohibited at railway crossings, on bridges/overpasses/flyovers and under them, as well as in tunnels (clause 10.7, subclauses "a", "b", "c").
A U-turn is a maneuver in which a vehicle changes its direction of travel to the opposite one. It requires sufficient space and good visibility so that the driver can safely assess the situation and not create an obstacle for other road users.
Clause 10.7 of the Traffic Rules of Ukraine directly establishes the places where a U-turn is prohibited. In particular, according to subclause b), it is not allowed to make a U-turn on bridges, overpasses, flyovers, and under them. Such sections are structurally limited: the carriageway is often narrower, there are barriers, there is no room for error, and any stop or turn across the flow sharply increases the risk of an accident.
Similarly, subclause v) of clause 10.7 prohibits U-turns in tunnels. In a tunnel, the width, visibility, and possibility of bypassing are usually limited, and the lighting and "enclosed" space make it more difficult for other drivers to timely perceive the maneuver. Therefore, a U-turn in a tunnel is dangerous regardless of traffic intensity.
Thus, in all three of the listed places, a U-turn is prohibited by the direct provision of clause 10.7 (subclauses b) and v) of the Traffic Rules, so the correct answer is the option that combines these points.
Therefore, the correct answer is "Answers 1, 2, and 3," since a U-turn is prohibited on bridges, overpasses, flyovers and under them, as well as in tunnels according to clause 10.7 b), v) of the Traffic Rules of Ukraine.
