Question without image
This exam question from the Traffic Rules of Ukraine concerns road safety during lane changes when a driver is merging in traffic. Such maneuvers are among the most common causes of conflict situations and accidents, as mistakes in judging distance, speed, or the "blind spot" force other road users to brake sharply or change their trajectory. That is why the theoretical driving exam checks not just a single "action," but the correct sequence of mandatory steps.
The question tests knowledge of Sections 9 "Warning Signals" and 10 "Starting Off and Changing Direction," with emphasis on the requirements of points 9.2, 10.1, and 10.3 of the Traffic Rules. The logic is as follows: the driver must signal in advance with the turn indicator, then make sure the maneuver is safe using mirrors and checking the "blind spot," and only then perform the lane change, while being sure to yield to vehicles in the lane they intend to enter (the term "yield" is defined in point 1.10). This is a comprehensive check of whether the candidate understands that changing lanes without signaling, without checking, or without yielding is a violation and creates danger.
If we analyze the answer options, each of the first three describes only part of the traffic rules requirements: signaling must be done in advance, but by itself does not make the maneuver safe; checking mirrors and the "blind spot" is mandatory, but without yielding to vehicles in the target lane, the lane change is still illegal; yielding is always required, but without signaling, other drivers cannot anticipate your actions. Therefore, only the comprehensive option is correct, which combines signaling, checking the situation, and yielding during the lane change according to point 10.3 of the Traffic Rules of Ukraine.
Clause 9.2 (Section 9 "Warning Signals")
Turn indicator signals must be given in advance before starting the maneuver and must be turned off immediately after its completion. The signal must not mislead other road users.
Brief application: before changing lanes to the right, the driver is required to turn on the right turn indicator in advance (and not "accompany" the maneuver with a delayed signal).
Clause 10.1 (Section 10 "Starting Off and Changing Direction")
Before starting off, changing lanes, turning, making a U-turn, or stopping, the driver must make sure that it will be safe and will not create obstacles or danger to other road users.
Brief application: before changing lanes to the right, the driver must check the traffic situation (in particular, using mirrors) and make sure that the maneuver is safe.
Clause 10.3 (Section 10 "Starting Off and Changing Direction")
When changing lanes, the driver must yield to vehicles moving in the same direction in the lane into which he intends to move.
Brief application: when changing lanes to the right, it is necessary to yield to vehicles already moving in the right lane that you want to occupy.
Clause 1.10 (term "Yield")
Yield — a requirement for a road user not to continue or resume movement or perform any maneuvers if this may force other road users who have the right of way to change their direction or speed.
Brief application: "yielding" when changing lanes means not starting/not continuing the maneuver in such a way that would force a vehicle in the target lane to brake or change trajectory.
That is, the correct answer is "Perform all the actions specified in answers 1, 2, and 3," given that according to the definition of the Traffic Rules, when changing lanes the driver is required to signal the turn in advance (clause 9.2), make sure the maneuver is safe (clause 10.1), and yield to vehicles in the lane being entered (clause 10.3, the term "yield" from clause 1.10).
When you decide to change lanes to the right while driving, this is considered a lane change, that is, a maneuver. Any maneuver in traffic must be predictable for others and safe, so it is performed not in a single action, but as a sequence of mandatory steps.
First, you must warn other road users in advance about your intention to change lanes: turn on the right turn signal. This should be done not "at the moment," but before starting the lane change, so that drivers behind and beside you have time to assess your actions.
Next, you need to make sure that the lane change will be safe. To do this, assess the traffic situation in the mirrors and be sure to check the right "blind spot" with a quick turn of your head, so as not to start the maneuver when there is already a vehicle in the adjacent lane that is not visible in the mirror.
After this, the requirement of paragraph 10.3 of the Traffic Rules of Ukraine applies: when changing lanes, the driver must yield to vehicles moving in the same direction in the lane into which he intends to move. For example, if someone is moving steadily in their lane to the right, or if a car in the right lane is approaching from behind at a higher speed, you do not have the right to "cut in"—you must let them pass and only then safely occupy the lane.
Thus, the correct answer is "Perform all the actions mentioned in answers 1, 2, and 3," since when changing lanes you need to signal, make sure the maneuver is safe, and yield to vehicles in the lane you are moving into (requirement of paragraph 10.3 of the Traffic Rules).
