In Portuguese traffic law, what is the legal blood alcohol limit (taxa de álcool no sangue / TAS) for standard non-professional drivers?
Answer and explanation
Correct answer: D. 0.50 grams per liter of blood
- Step 1: Standard alcohol threshold. Step 2. Under Article 81, a driver is considered driving under the influence of alcohol when their blood alcohol concentration is equal to or exceeds 0.50 g/l. Answer: 0.50 grams per liter of blood. Why not the others: 0.20 g/l is for novice and professional drivers; 0.80 g/l is the threshold for very serious infractions; zero is not the standard regime.
