UAЧи є антифриз отруйною речовиною?
Question without image
This is an exam question from the section on safe operation of the vehicle and the driver's personal safety. It does not concern maneuvering or road signs, but rather responsible handling of technical fluids, which directly affects the health of people inside and around the car. In the theoretical exam, such knowledge is tested to ensure that the driver understands the risks during vehicle maintenance and does not allow dangerous situations at home or on the road.
In the context of the Traffic Rules of Ukraine, it should be noted that the current traffic regulations do not contain a separate section defining the toxicity of antifreeze or regulating its properties. Therefore, the question pertains to general knowledge of safety and technical literacy of the driver, which complement the requirements of the Traffic Rules. In practice, most coolants are made on the basis of ethylene glycol, and such compositions are highly toxic if ingested, so the correct direction of the answer is unambiguous.
The analysis of the options is simple: the statement that antifreeze is not poisonous is incorrect, because common glycol-based antifreezes can cause severe poisoning even in small amounts. The option stating that only the concentrate is dangerous is also incorrect: working mixtures with water remain toxic, and the risk is determined by the chemical base (primarily ethylene glycol), not just the concentration. That is why the correct statement is about high toxicity.
The practical significance for the driver within the rules of the road and the culture of safe operation is as follows: do not pour coolant into food containers, do not leave it accessible to children and animals, immediately eliminate leaks, and do not ignore a sweet smell in the cabin, which may indicate a problem with the heater radiator. Such understanding helps to use the car safely and to answer exam questions correctly during preparation for the test.
Clauses of the Traffic Rules of Ukraine checked by this question
The current Traffic Rules of Ukraine do not contain clauses that define antifreeze as a poisonous/non-poisonous substance or include any requirements regarding the toxicological properties of cooling fluids (antifreeze). This exam question belongs to the block of general knowledge about the safe operation of a vehicle and health safety (toxicity of technical fluids), rather than to norms directly regulated by the Traffic Rules.
Therefore, the correct answer is "Yes, very poisonous," given that such properties of antifreeze are not regulated by the Traffic Rules (the question goes beyond the scope of the Traffic Rules) and is based on generally known safety requirements for handling technical fluids.
Antifreeze in a car is a coolant that is necessary for the normal operation of the engine at various temperatures. It is used in the cooling system, as well as in some fluids that operate in cold conditions. But it is important to understand: antifreeze is not a neutral “technical water,” but contains chemicals that are dangerous to humans.
The most common antifreezes are made on the basis of ethylene glycol. These fluids are very toxic, especially if they get inside the body. Even a small amount can cause severe poisoning: at first, symptoms may resemble alcohol intoxication, then there may be coordination disorders, weakness, vomiting, and in severe cases — loss of consciousness and convulsions. Therefore, antifreeze is classified as a dangerous poisonous substance.
In practical terms for the driver, this means that antifreeze should not be poured into household containers, left open, or accessible to children and animals. It is also dangerous to ignore leaks: if antifreeze gets on hot parts or evaporates, its vapors can irritate the eyes and respiratory tract, especially when, due to a malfunction of the heating system, they enter the cabin.
Thus, the correct answer is "Yes, very poisonous," since most antifreezes contain toxic components (in particular, ethylene glycol) and can cause severe poisoning, especially if ingested.
