Question 1 of 27070

Under Title 33 CFR, at or above what level of "Blood Alcohol Concentration" would constitute a crew member as being considered "Under the Influence of Alcohol" on a commercial vessel?

🔍 Key Concepts

• 33 CFR Part 95 – Operating a Vessel While Under the Influence of Alcohol (focus on commercial vessel crewmembers) • Difference between a percentage (e.g., 0.04%) and a decimal fraction of 1.0 • How Blood Alcohol Concentration is typically expressed in regulations (grams of alcohol per 100 milliliters of blood)

💭 Think About

• Look up the specific BAC limit in 33 CFR for crewmembers on commercial vessels and write it down as a percent first. • Convert that percent BAC into a pure decimal number (fraction of 1.0) and see which choice it lines up with. • Compare how small the answer choices are to common legal limits (like 0.08% for driving) and think about whether they are written as percents or pure decimals.

✅ Before You Answer

• Verify in 33 CFR Part 95 the stated BAC limit for a commercial vessel crewmember being considered under the influence. • Be sure you understand that 0.04% is not the same as 0.004 or 0.0004 – convert carefully. • Check whether the choices are written as a fraction of 1.0 (e.g., 0.04 = 4/100) rather than as a percent, and align them with the regulatory percent you found.
