DRE Legal & Ethical Issues 3 — Questions and Answers
Question 1: A DRE officer who exaggerates clinical signs in a report to secure a conviction has committed:
- Acceptable professional advocacy
- Perjury and falsification of records (Correct answer)
- A minor procedural violation only
- An act protected by qualified immunity
Correct answer: Perjury and falsification of records
Deliberately overstating or fabricating findings constitutes perjury and records falsification, which are criminal offenses and grounds for decertification.
Question 2: Under ADA (Americans with Disabilities Act) considerations, a DRE must be aware that some observable signs may be caused by:
- Voluntary drug use only
- A medical condition unrelated to drug impairment (Correct answer)
- Deliberate simulation by the subject
- Residual alcohol from the previous day
Correct answer: A medical condition unrelated to drug impairment
Medical conditions such as diabetes, epilepsy, or Parkinson's disease can mimic drug-impairment signs and must be considered before drawing conclusions.
Question 3: The DRE's role in court is best described as that of:
- A prosecutor's advocate
- An objective expert witness (Correct answer)
- A defense consultant
- An investigating grand juror
Correct answer: An objective expert witness
DREs testify as expert witnesses and must present findings objectively, regardless of which party called them.
Question 4: Which standard governs the admissibility of DRE expert testimony in federal courts and many state courts following Daubert v. Merrell Dow Pharmaceuticals?
- Frye general-acceptance standard
- Daubert reliability and relevance standard (Correct answer)
- Brady materiality standard
- Kumho strict peer-review standard
Correct answer: Daubert reliability and relevance standard
Daubert requires trial judges to ensure expert testimony is based on sufficient facts, reliable methodology, and appropriately applied principles.
Question 5: If a subject invokes the right to counsel during the DRE evaluation, the officer must:
- Continue the evaluation and provide an attorney afterward
- Immediately cease questioning and allow attorney access (Correct answer)
- Proceed only with the physical portion of the evaluation
- Request a supervisor to authorize continuation
Correct answer: Immediately cease questioning and allow attorney access
Once a subject invokes the right to counsel, custodial interrogation must cease; however, non-testimonial physical evaluations may continue in some jurisdictions.

- Reduce laboratory processing time
- Ensure the sample's integrity and admissibility in court (Correct answer)
- Comply with HIPAA privacy requirements
- Satisfy FBI reporting obligations
Correct answer: Ensure the sample's integrity and admissibility in court
An unbroken chain of custody documents who handled a sample, preventing tampering claims and ensuring the evidence is admissible.
Question 7: A DRE officer who learns that a supervisor instructed falsification of a report is ethically obligated to:
- Follow the supervisor's instructions to preserve departmental unity
- Report the misconduct through appropriate channels or chain of command (Correct answer)
- Destroy the original report to avoid involvement
- Wait until the case is resolved before acting
Correct answer: Report the misconduct through appropriate channels or chain of command
Officers have a professional and often legal duty to report misconduct, including supervisory misconduct, through established reporting mechanisms.
