Question: What is the maximum number of standard drinks an average adult can typically consume before reaching the legal impaired driving limit (BAC of 0.05) in Alberta?

Answer options:

• 1-2 standard drinks. ✅ 3-4 standard drinks.
• 5-6 standard drinks.
• It entirely depends on the person and cannot be estimated.

Correct answer: 3-4 standard drinks.

Explanation: While individual factors vary, generally, an average adult male can reach a BAC of 0.05 after 3 non-alcoholic drinks an hour and 1-2 standard drinks within a short period. Factors like gender, weight, and consumption rate can significantly alter this. However, 1-2 standard drinks is a reasonable general guideline, emphasizing that impairment can occur with relatively few drinks. Option A is too low for the 0.05 limit typically. Option B is considered a general guideline. Options A and D do not give the best general answer. Option C is too high.
