35.106. Can a seat belt effectively protect a reclining passenger?
UAЧи може ремінь безпеки ефективно спрацювати захистити лежачого пасажира?
This exam question from the Traffic Rules of Ukraine concerns passive safety and the rules for using seat belts, which directly affect the risk of injury during sudden braking or a traffic accident. In the theoretical exam, such tasks test understanding not only of the formal requirement to "be buckled up," but also of how the seat belt actually works and why it is effective only when the body is in the correct position.
The question checks knowledge of the section of the Traffic Rules regarding the responsibilities of the driver and passenger concerning seat belts (specifically paragraphs 2.3(c) and 5.2(b) of the Traffic Rules of Ukraine). The logic is simple: a standard three-point seat belt is designed for a sitting position, where the shoulder part passes over the shoulder and chest, and the lap part lies snugly on the pelvis. In a lying position, the belt cannot be placed and tightened "as intended," it shifts to the abdomen, ribs, or neck, does not properly secure the torso, and during a collision a person may slide or "submarine" under the belt, which sharply reduces the protective effect and even increases the risk of injury.
That is why the option stating that a seat belt can effectively protect a lying passenger is incorrect: in practice, it does not provide the proper fixation for which it is designed. The correct answer emphasizes the key idea of the traffic rules: a seat belt works most effectively only in a sitting position and when properly fitted, and transporting a person lying down requires special solutions and equipment, as in medical transport.
Clause 2.3 (subclause "v")
To ensure road safety, the driver is obliged to: use seat belts and not transport passengers who are not wearing seat belts, if the vehicle is equipped with seat belts according to its design.
Explanation of application: the question checks the understanding that transporting a passenger must be done in compliance with the seat belt requirement; in a lying position, the standard seat belt cannot actually be positioned and tightened on the body as intended by design, so it does not provide proper restraint and protection.
Clause 5.2 (subclause "b")
The passenger is obliged: in vehicles equipped with seat belts, to wear them.
Explanation of application: the question additionally checks that the obligation to use a seat belt is imposed not only on the driver (control), but also on the passenger (direct execution), and that the seat belt is designed to work effectively in the standard (sitting) position.
That is, the correct answer is "No.", given that according to the Traffic Rules the passenger must be fastened with a seat belt, and in a lying position the standard belt cannot be used as intended (does not provide proper body restraint), so it cannot effectively protect a lying passenger.
The Traffic Rules of Ukraine establish a general requirement: while driving, the driver and passengers in the vehicle must use seat belts if the seats are equipped with them. The idea of the seat belt is simple: it keeps the body in the correct position on the seat during sudden braking or a collision, so that a person does not move by inertia and does not hit the interior elements.
At the same time, it is important to understand how exactly the seat belt "works." Structurally, a three-point seat belt is designed for a seated passenger: the shoulder part passes across the chest and shoulder, and the lap part lies snugly on the pelvis. Only in this way can the belt take on the load and transfer it to the strong parts of the body, keeping the person on the seat.
If the passenger is lying on the seat, the belt physically cannot be positioned and tightened as intended by the manufacturer. The lap part shifts to the abdomen or ribs, the shoulder part may pass over the neck, back, or may not restrain the torso at all. In the event of sudden braking or impact, such a passenger will begin to slide, "submarine" under the belt, or twist, and the belt will not provide proper restraint and may even cause additional injuries due to improper load distribution.
Therefore, although the lying position itself is not a separate "prohibition," the answer in this question concerns the effectiveness of a standard seat belt. In a lying position, a standard seat belt cannot fully perform its protective function because it cannot fit snugly and correctly or restrain the body as it does in a seated position.
Thus, the correct answer is "No," since a standard seat belt is designed to restrain a person in a seated position, and for a passenger who is lying down, it cannot be properly positioned and tightened, and therefore does not provide effective protection.
