35.124. The consumption of even a small dose of alcohol:
UAВживання навіть невеликої дози алкоголю:
This exam question from the Traffic Rules of Ukraine concerns road safety and sober driving. During a trip, the driver continuously perceives signals from the road, assesses the situation, anticipates the actions of other participants, and performs maneuvers. Even a brief delay between "noticing a danger" and "starting to act" can increase the stopping distance and make an accident inevitable, which is why the topic of alcohol's influence is directly related to the risk of accidents.
The question tests knowledge of the section of the traffic rules regarding the driver's duties and prohibitions, specifically the requirement to be attentive and respond appropriately to changes in the situation (item 2.3), as well as the prohibition against driving under the influence of alcohol or substances that reduce attention and reaction speed (item 2.9). For the theoretical exam, it is important to understand that even small doses of alcohol already slow down the nervous system: the driver notices threats later, takes longer to make decisions, and acts more slowly, meaning the reaction time increases.
The analysis of the answer options is logical: the statement that alcohol "does not affect" contradicts both physiology and the content of the traffic rules, which directly mention reduced attention and reaction speed. The claim about "improving skills" is a dangerous myth: alcohol often gives a false sense of confidence, but in fact worsens coordination, accuracy in assessing speed and distance, and self-control. That is why the correct option is the one about the effect on reaction time, as this is the key parameter on which the driver's ability to brake in time, avoid an obstacle, or properly respond to a pedestrian or sudden braking ahead depends.
Clause 2.9 (driver's duties and rights, prohibitions, subclause "a")
The driver is prohibited from: a) driving a vehicle while under the influence of alcohol, drugs, or other intoxication, or under the influence of medicinal products that reduce attention and reaction speed.
This clause directly links alcohol consumption with reduced attention and reaction speed (i.e., increased reaction time), which is what the exam question checks.
Clause 2.3 (driver's duties, subclause "b")
To ensure road safety, the driver is obliged to: b) be attentive, monitor the road situation, respond appropriately to its changes, monitor the proper placement and securing of cargo, the technical condition of the vehicle, and not be distracted from driving while on the road.
Alcohol (even in small doses) impairs the ability to "respond appropriately to changes in the road situation," that is, increases reaction time, which contradicts the requirements of attentiveness and timely response.
Therefore, the correct answer is "Affects the driver's reaction time," given that according to the definition of the Traffic Rules, the driver is prohibited from driving while intoxicated, in particular under the influence of substances that reduce attention and reaction speed (clause 2.9 a), and the driver is also obliged to be attentive and respond appropriately to changes in the road situation (clause 2.3 b).
While driving a vehicle, the driver constantly performs a chain of actions: notices a change in the road situation, assesses it, makes a decision, and only then presses the brakes, changes lanes, or avoids an obstacle. The Traffic Rules require attentive driving and control of the vehicle, which means that the time between "saw the danger" and "managed to react" must be minimal.
Even a small dose of alcohol affects exactly this interval. Alcohol slows down the nervous system: the driver notices important signals later (a pedestrian at a crosswalk, sudden braking ahead, a change in the traffic light), takes longer to think over the situation, and performs actions more slowly. Because of this, reaction time increases, and therefore the stopping distance also increases, even if the speed has not changed.
In practice, it looks like this: in a normal state, the driver manages to react to sudden braking of the car in front and immediately presses the brakes. After consuming alcohol, the reaction becomes slower: braking starts later, and those same meters that were "missing" turn into a collision. The same applies to a pedestrian: a delay of fractions of a second can mean that the driver will start braking only when the danger has become critical.
That is why legislation and road safety rules consider driving after consuming alcohol to be a dangerous condition: even small concentrations reduce attention and the accuracy of assessing the situation, and the key point for the exam question is — they increase reaction time.
Therefore, the correct answer is "Affects the driver's reaction time," because even a small dose of alcohol slows down perception, assessment of the situation, and performance of actions, causing the driver to react later and not have time to prevent danger in time.
