Which BAC pair correctly distinguishes commercial vessels and pleasure crafts?

Commercial .04; Pleasure .08 Commercial .08; Pleasure .04 Commercial .04; Pleasure .04 Commercial .04; Pleasure .10

Correct Answer:

Commercial .04; Pleasure .08

Explanation:

Operators of commercial vessels are held to a stricter blood alcohol limit because they have a duty to the safety of the crew, passengers, and cargo, and must be able to respond quickly to emergencies. That stricter limit is 0.04 BAC. Pleasure-craft operators, by contrast, are typically governed by a higher limit, commonly 0.08 BAC, which aligns with many automotive and recreational standards. Therefore, the correct pairing is commercial at 0.04 and pleasure at 0.08. The other options either swap the limits, set them equal, or assign a higher limit to the pleasure category that doesn’t match standard practice.
