11.10. Along which trajectory may the driver of the white vehicle enter the reversible lane when turning?
UAПо якій траєкторії водій білого автомобіля може виїжджати на смугу з реверсивним рухом при повороті?
This exam question from the Traffic Rules of Ukraine tests the ability to safely make a turn onto a road with a reversible lane. Such lanes operate with a variable direction, so a mistake when entering them can lead to driving into oncoming traffic or onto a lane where movement is temporarily prohibited. In the context of the theoretical exam, it is important to understand that reversible traffic is always "tied" to the signals of the reversible traffic light and the corresponding road markings, and not just to the driver's desire to take a more convenient lane.
The question belongs to the section of the Traffic Rules concerning the positioning of vehicles on the roadway and maneuvering, with an emphasis on point 11.12 of the Traffic Rules of Ukraine. Additionally, it is based on the general rule for making a right turn as close as possible to the right edge (point 10.5), as well as understanding signs 5.13 and 5.15, the signals of the reversible traffic light (point 8.7.4), and marking 1.9. The logic is as follows: first, the driver completes the turn into their "own" regular lane, and only then, after passing the reversible traffic light with a permissive signal, may, if necessary, change to the reversible lane.
The analysis of the answer options comes down to the fact that "any" trajectory is incorrect, because the traffic rules directly restrict the moment of entering the reversible lane: it is not allowed before passing the traffic light. A trajectory that leads the car onto the reversible lane immediately during the turn contradicts point 11.12, as the driver has not yet confirmed the permissive mode for this lane. Instead, the trajectory that leaves the car in the right lane after the turn and allows changing to the reversible lane only after the traffic light complies with the requirements of the Traffic Rules and is correct for this exam task.
Clause 11.12
A driver who is turning onto a road with a reversible lane may change to that lane only after passing the reversible traffic light displaying a permissive signal, and if this does not contradict clauses 11.2, 11.5, and 11.6 of these Rules.
Clause 10.5
When turning right, you must keep as close as possible to the right edge of the carriageway.
Clause 8.7.4
To regulate the movement of vehicles on streets, roads, or on lanes of the carriageway where the direction of movement can be changed to the opposite, reversible traffic lights are used with a red X-shaped signal and a green signal in the form of a downward arrow. These signals prohibit or permit movement on the lane above which they are located. The main signals of the reversible traffic light may be supplemented by a yellow signal in the form of an arrow slanting diagonally down to the right, the activation of which prohibits movement on the lane marked on both sides by road marking 1.9, and informs about the change of the reversible traffic light signal and the need to change to the lane to the right. If the signals of the reversible traffic light located above the lane marked on both sides by road marking 1.9 are off, entry onto this lane is prohibited.
Clause 33.5 — 33 "Road Signs", 5 "Informational and Directional Signs", sign 5.13 "Road with Reversible Traffic"
Sign 5.13 "Road with Reversible Traffic" is used to indicate the beginning of a section of road where the direction of traffic on one or more lanes can be changed to the opposite.
Clause 33.5 — 33 "Road Signs", 5 "Informational and Directional Signs", sign 5.15 "Exit onto a Road with Reversible Traffic"
Sign 5.15 "Exit onto a Road with Reversible Traffic" is used to indicate the exit onto a road marked with sign 5.13 "Road with Reversible Traffic" and is installed at all side exits.
Clause 34.1 — 34 "Road Markings", 1 "Horizontal Markings", marking 1.9
Marking 1.9 indicates the boundaries of lanes where reversible traffic regulation is carried out (the direction of movement can be changed), and is related to the requirements of reversible traffic lights regarding permission/prohibition of movement on the corresponding lane.
That is, the correct answer is "Along B.", given that according to the definition of the Traffic Rules, entering (changing to) a reversible lane after turning is allowed only after passing the reversible traffic light with a permissive signal (clause 11.12), and the right turn itself is performed by approaching the right edge of the carriageway (clause 10.5).
When turning onto a road with a reversible lane, the driver must remember: the reversible lane can operate in different directions at different times, and sometimes entry onto it is completely prohibited. That is why the procedure for entering such a lane is strictly regulated by the Rules.
The sign warning about entering a road with a reversible lane means that after the turn, there will be a lane whose direction is determined by a reversible traffic light. However, the mere presence of such a lane does not give the right to immediately occupy it while turning.
According to clause 11.12 of the Traffic Rules, a driver turning onto a road with a reversible lane is allowed to change into it only after passing the reversible traffic light with a permissive signal. That is, first you need to complete the turn into the regular lane in your direction, and only then, making sure the traffic light permits it and the maneuver is safe, change into the reversible lane if necessary.
If you drive along trajectory A, the driver actually enters the reversible lane before passing the reversible traffic light and before being able to make sure that movement in their direction is allowed. This contradicts clause 11.12 and creates a risk of entering a lane where movement may be prohibited or organized in the opposite direction.
Trajectory B meets the requirements: the driver turns into their own lane, moves toward the reversible traffic light, and only after passing it and with a permissive signal can change into the reversible lane, if it is necessary and safe.
Therefore, the correct answer is "Along B.", since changing into the reversible lane is allowed only after passing the reversible traffic light with a permissive signal, and trajectory B ensures exactly this.
