    49 CFR Part 40 requires the specimen temperature to be between 90°F and 100°F (32–38°C) when measured within 4 minutes of collection.

  3. Which of the following correctly lists the five drug categories tested in a standard DOT urine drug test?

  4. At what blood alcohol concentration (BAC) level is a DOT-regulated employee considered to have an alcohol test violation?

    Answer: 0.04 or greater

  6. What is the primary purpose of the Federal Chain of Custody Form (CCF) in DOT drug testing?

    Answer: To track the specimen from collection through laboratory analysis and reporting

    The CCF documents every transfer of custody, ensuring the integrity and traceability of the specimen from collection to laboratory result.

  7. How long must a certified laboratory retain a confirmed positive, adulterated, or substituted urine specimen under 49 CFR Part 40?

    Answer: At least 1 year

    Laboratories must retain confirmed positive, adulterated, or substituted specimens for at least one year from the date the result was reported.
