13.8. Which rule should drivers follow in case of limited oncoming passing on road sections marked with 'Steep Ascent' and 'Steep Descent' signs?
UAЯким правилом повинні керуватися водії в разі обмеженого зустрічного роз'їзду на ділянках доріг, позначених знаками «Крутий підйом» і «Крутий спуск»?
This exam question from the Traffic Rules of Ukraine tests knowledge of safe passing rules on narrow road sections during ascent and descent, when oncoming passage is complicated. In real traffic, such situations often arise in mountainous areas or on roads with significant inclines, where a mistake with priority can lead to dangerous maneuvers, sudden braking, or even loss of vehicle control.
In terms of content, it relates to the topic of traffic rules regarding oncoming passing and the positioning of vehicles on the carriageway, specifically to the requirements of clause 13.4 of the Traffic Rules (as well as related concepts such as "give way," "obstacle," and "priority" from the terminology section). The key idea: the general rule that the driver on whose side there is an obstacle or whose vehicle's dimensions hinder passing must yield, is supplemented by a special priority on sections marked with signs 1.6 "Steep Ascent" and 1.7 "Steep Descent." In this situation, priority is given to the vehicle moving uphill, and the driver going downhill must give way, which is what the theoretical exam checks.
Analyzing the answer options helps to avoid confusion: statements about an obstacle in one's lane and about dimensions hindering passing are correct as a basic rule for ordinary narrow places, but they are not the main ones specifically for the case of "steep ascent/descent," because a special provision of clause 13.4 applies there. Therefore, the option giving priority to the one moving downhill is incorrect, and the combined option is also unsuitable, since under the conditions described by the signs, priority is determined by the direction of movement on the incline. The practical meaning is simple: it is harder to stop and start again uphill without the risk of rolling back, whereas on a descent, a controlled stop and resumption of movement are usually easier.
Clause 13.4
If passing oncoming vehicles is difficult, the driver whose lane contains an obstacle or whose vehicle dimensions hinder oncoming traffic must yield. On road sections marked with signs 1.6 “Steep ascent” and 1.7 “Steep descent,” in the presence of an obstacle, the driver of the vehicle moving downhill must yield.
Brief application: this is a special priority rule specifically for sections marked 1.6/1.7, when passing is difficult (narrow) and there is an obstacle/vehicle dimensions hinder — in such a case, priority is given to the vehicle moving uphill, and the one moving downhill is obliged to yield.
Clause 1.10 (term “Yield (do not create an obstacle)”)
Yield (do not create an obstacle) — a requirement for a road user not to continue or resume movement, nor to perform any maneuvers, if this may force other road users who have priority to change their direction or speed.
Brief application: in the context of clause 13.4, the driver going downhill must refrain from continuing/resuming movement or maneuvers so as not to force the oncoming vehicle (which has priority) to change speed or direction.
Clause 1.10 (term “Obstacle to movement”)
Obstacle to movement — a stationary object within the lane (except for a vehicle moving ahead in the same lane), which does not allow movement to continue in this lane.
Brief application: the “presence of an obstacle” on a section with signs 1.6/1.7 is the condition under which the special requirement of clause 13.4 is triggered — the one moving downhill must yield.
Clause 1.10 (term “Priority”)
Priority — the right to move first in relation to other road users.
Brief application: according to clause 13.4, on a narrow section with signs 1.6/1.7, priority is given to the vehicle moving uphill (accordingly, the one moving downhill must yield).
Clause 33.1 — 33 “Road signs”, 1 “Warning signs”, sign 1.6 “Steep ascent”
Sign 1.6 “Steep ascent” — a section of road with a steep ascent.
Brief application: indicates the conditions under which (together with sign 1.7 in the opposite direction) the special passing rule from clause 13.4 applies.
Clause 33.1 — 33 “Road signs”, 1 “Warning signs”, sign 1.7 “Steep descent”
Sign 1.7 “Steep descent” — a section of road with a steep descent.
Brief application: in combination with the condition “difficult oncoming passing” and “presence of an obstacle” directly refers to clause 13.4, which establishes the obligation of the driver going downhill to yield.
That is, the correct answer is: “The driver of the vehicle moving downhill must yield,” given that according to the definition in the Traffic Rules, clause 13.4 directly states: on sections marked with signs 1.6 “Steep ascent” and 1.7 “Steep descent,” in the presence of an obstacle and difficult oncoming passing, it is specifically the driver moving downhill who is obliged to yield.
Imagine a narrow section of road in a mountainous area where only two oncoming vehicles can pass each other in turn. This situation is called a limited (difficult) oncoming passing. Warning signs "Steep ascent" and "Steep descent" are installed on this section, meaning the road has a significant slope.
The general rule from paragraph 13.4 of the Traffic Rules is as follows: when oncoming passing is difficult, the driver who has an obstacle on their side, or whose vehicle by its dimensions actually obstructs the oncoming movement, must yield. That is, usually the priority depends on whom the narrowing or obstacle "interferes" with.
But for sections marked with the signs "Steep ascent" and "Steep descent," the same paragraph 13.4 establishes a special rule: if there is a need for passing in limited conditions on such a section, priority is given to the vehicle moving uphill. Accordingly, the one descending must yield.
The logic of this rule is practical and safety-oriented. It is much harder for a driver moving uphill to stop and then start moving again on a slope: the car may roll back, greater traction is needed, and more time is required to start moving. On the other hand, it is easier for a vehicle going downhill to briefly stop and continue moving, controlling speed with the brakes. That is why the Traffic Rules give priority to the one who objectively finds it harder to resume movement uphill.
Therefore, the correct answer is "The driver of the vehicle descending must yield," because on sections with the signs "Steep ascent" and "Steep descent," paragraph 13.4 of the Traffic Rules establishes a special priority for the vehicle moving uphill, so the driver going downhill is obliged to yield.
