DRE Project Planning & Execution 3 — Questions and Answers
Question 1: A DRE supervisor is planning a quality assurance review of completed DRE reports. Which metric is the most reliable indicator that the protocol was executed properly?
- The subject was ultimately convicted
- Toxicology results matched the DRE's drug category opinion (Correct answer)
- The DRE obtained a confession from the subject
- The arresting officer agreed with the DRE's conclusion
Correct answer: Toxicology results matched the DRE's drug category opinion
Toxicological confirmation of the drug categories identified in the DRE's opinion is the gold-standard measure of protocol execution accuracy.
Question 2: When planning court testimony for a DRE case, which element of preparation is most critical for withstanding cross-examination?
- Memorizing the subject's criminal history
- Thorough review of all 12-step evaluation documentation and the ability to explain each finding (Correct answer)
- Obtaining a plea agreement to avoid testimony
- Preparing the toxicologist to testify before the DRE
Correct answer: Thorough review of all 12-step evaluation documentation and the ability to explain each finding
Defense attorneys frequently challenge DRE testimony by probing specific findings; mastery of the evaluation documentation ensures credible, consistent answers.
Question 3: During execution of the DRE protocol, the DRE notices the subject's pupil sizes are unequal. What is the appropriate next step?
- Stop the evaluation and refer to a physician
- Document the finding as resting pupil size inequality (anisocoria) and continue the evaluation (Correct answer)
- Assume the measurement was inaccurate and re-measure once
- Report the finding to the arresting officer and terminate the exam
Correct answer: Document the finding as resting pupil size inequality (anisocoria) and continue the evaluation
Anisocoria is a documented physiological variant; the DRE records it and considers it when interpreting overall findings but does not stop the evaluation.
Question 4: A department is planning its annual DRE training program. Which requirement must be met to maintain an officer's DRE certification?
- Completing 40 hours of refresher narcotics training annually
- Meeting continuing education and minimum evaluation requirements set by IACP/NHTSA (Correct answer)
- Passing a polygraph examination each year
- Conducting at least 100 DRE evaluations per calendar year
Correct answer: Meeting continuing education and minimum evaluation requirements set by IACP/NHTSA
IACP/NHTSA standards require DREs to complete continuing education and a minimum number of drug influence evaluations to maintain active certification.
Question 5: In planning the evidence collection phase of a DRE evaluation, which specimen provides the most comprehensive toxicological picture for most drug categories?
- Saliva only, as it reflects current impairment
- Urine only, as it has the longest detection window
- Blood, because it best reflects the drug's concentration at or near the time of impairment (Correct answer)
- Hair follicle samples, as they provide a 90-day drug history
Correct answer: Blood, because it best reflects the drug's concentration at or near the time of impairment
Blood specimens most accurately reflect drug concentrations at the time of the evaluation, making them the most probative evidence of recent impairment.
Question 6: When executing the walk-and-turn divided attention test during a DRE evaluation, how many clues out of eight indicate likely impairment?
- One or more clues
- Two or more clues (Correct answer)
- Four or more clues
- All eight clues must be present
Correct answer: Two or more clues
NHTSA research established that two or more clues on the walk-and-turn test reliably indicate impairment in the validated scoring system.
Question 7: A DRE is planning the execution order for the 12-step protocol and must determine when to conduct the pupillary examination under different lighting. What is the correct sequence of lighting conditions?
- Normal room light, then near total darkness, then direct light (Correct answer)
- Direct light, then normal room light, then near total darkness
- Near total darkness only to avoid any contamination
- Indirect light first, then direct light, then fluorescent light
Correct answer: Normal room light, then near total darkness, then direct light
The DRE pupillary exam protocol requires measuring pupil size in room light, near-total darkness, and then under direct light to assess pupillary response across conditions.
