The final reported BAC when multiple samples are collected is based on which sample?

• A. The higher BAC sample
• B. The lower BAC sample
• C. The first BAC sample
• D. The last BAC sample

Answer: (B)

When multiple BAC samples are collected, the final reported BAC is based on the lowest reading. This conservative approach protects against overstating impairment due to measurement variability, sample degradation, or handling errors. If one sample ends up higher than another, using the lower value helps ensure fairness by not crediting a higher BAC that might be due to a transient issue with a particular sample. In practice, the different samples are important and may be reviewed, but the value used for reporting tends to reflect the most reliable, lower result to avoid inflating the BAC.
