33.1.49. In which of the following places is this road sign installed?
UAУ якому з місць встановлюється даний дорожній знак?
This is an exam question from the Traffic Rules of Ukraine concerning road signs and the safe orientation of the driver in areas where the road trajectory changes sharply. Understanding such signs is important to prevent leaving the roadway, to choose the correct speed and trajectory, especially on dangerous curves and near obstacles.
The question tests knowledge of Section 33 of the Traffic Rules, in particular warning signs (paragraph 33.1) and the official purpose of sign 1.4.2 "Direction of the turn." According to the Traffic Rules, this sign is used as a directional guide: it shows exactly where the road turns (in this case, to the left) in an area that is usually previously marked with "Dangerous turn" signs (1.1 or 1.2), and can also indicate the direction to bypass an obstacle. That is, during the theoretical exam, it is important to distinguish a sign that warns of danger from a sign that directly at the location indicates the direction of further movement.
The analysis of answer options comes down to the fact that "dangerous shoulder" and "strong side wind" in the Traffic Rules of Ukraine have separate warning signs, so 1.4.2 is not installed to indicate these factors. Instead, it is placed exactly where it is necessary to clearly show the direction of a road turn or bypassing an obstacle, which corresponds to the definition from Section 33 and helps the driver to orient correctly, taking into account right-hand traffic in Ukraine.
Clause 33.1 — 33 "Road signs", 1 "Warning signs"
Warning signs inform drivers about approaching a dangerous section of the road and the nature of the danger.
Clause 33.1 — 33 "Road signs", 1 "Warning signs", sign 1.4.2 "Direction of the turn"
Indicates the direction of the road turn (left movement), marked by sign(s) 1.1 "Dangerous right turn" or 1.2 "Dangerous left turn", as well as the direction of detour around an obstacle on the road. Installed at locations indicating the direction of the road turn.
Brief explanation of application: this sign is used directly at the place where it is necessary to visually indicate the direction of the road turn (or detour of an obstacle), and not to indicate the danger itself with warning sign 1.1/1.2 on the approach to the section.
That is, the correct answer is "At locations indicating the direction of the road turn.", given that according to the definition in the Traffic Rules in the description of sign 1.4.2 it is directly stated: it "is installed at locations indicating the direction of the road turn".
Road sign 1.4.2 from section 33 of the Traffic Rules of Ukraine belongs to the warning signs and is used as a directional guide for the driver. In its meaning, it does not "warn about danger" as a separate independent sign, but shows exactly where the road turns at the nearest section.
It is installed directly at the place where the trajectory of the road changes and the driver needs to clearly understand the direction of further movement. For example, when there is a sharp left turn ahead and it is important to orient yourself in advance to the direction of the road, such a sign is placed right at the turn so that the driver does not continue straight and does not leave the roadway.
It is important not to confuse this sign with signs that indicate other dangerous factors. For a dangerous roadside or sections with strong side winds, the Traffic Rules provide separate warning signs, so 1.4.2 is not used for such situations. Likewise, this sign does not replace the warning sign "Dangerous turn," but only indicates the direction of the turn directly at the location.
Therefore, the correct answer is "At places indicating the direction of the road turn," since sign 1.4.2 is intended precisely to indicate the direction in which the road turns at a specific section.
