Show the correct answer
Correct answer
A. 0.2 ‰.
Explanation
In the drawing you can see a red prohibition symbol, and inside it a crossed-out bottle with a percent symbol and car keys. Driving a motor vehicle is prohibited from a blood alcohol concentration of 0.2 per mille - answer A.
The Road Traffic Act prohibits a person who is intoxicated or after drinking alcohol from driving a vehicle. The Act on Upbringing in Sobriety and Counteracting Alcoholism states that the state after drinking alcohol starts at a concentration of 0.2 per mille in the blood, and above 0.5 per mille it is already intoxication. The values of 0.1 per mille (answer B) and 0.05 per mille (answer C) are below the legal threshold - such trace values may come, for example, from some medicines, and mouthwash can briefly raise the breathalyser result. However, do not treat the threshold as a limit up to which you may drink: the body burns alcohol slowly, and even 0.2 per mille slows down your reactions. For driving after drinking alcohol the law provides for a high fine and a driving ban.
Legal basis: Art. 45 para. 1 point 1 of the Road Traffic Act (Prawo o ruchu drogowym); Art. 46 para. 2 and 3 of the Act on Upbringing in Sobriety and Counteracting Alcoholism
