SECTION I: Introduction, Definitions & Legal Foundations
(Q1–25)
1. Which of the following best defines a drug according to the Federal Food, Drug, and
Cosmetic Act (FDCA)?
A. Any substance intended for the diagnosis, cure, mitigation, treatment, or prevention
of disease
B. Any article recognized in the official United States Pharmacopoeia
C. Any substance intended to affect the structure or function of the body
D. All of the above
Answer: D
Rationale: The FDCA defines a drug broadly to include articles intended for diagnosis,
cure, mitigation, treatment, or prevention of disease; articles recognized in official
compendia; and articles intended to affect the structure or function of the body .
2. Which regulatory body is primarily responsible for approving new prescription drugs
in the United States?
A. DEA
B. FDA
C. CDC
D. OSHA
,Answer: B
Rationale: The Food and Drug Administration (FDA) is the federal agency responsible
for evaluating and approving new prescription drugs for safety and efficacy before they
can be marketed .
3. The generic name of a drug is best described as:
A. The proprietary name assigned by the manufacturer
B. The nonproprietary name approved by the FDA
C. The chemical name describing molecular structure
D. The brand name used in marketing
Answer: B
Rationale: The generic name is the nonproprietary, official name of a drug approved by
the FDA and is not owned by any manufacturer .
4. Within the DEC Program, a drug is defined as:
A. Any substance that, when taken into the human body, can impair the ability of the
person to operate a vehicle safely
B. Any illegal substance
C. Any prescription medication
D. Any substance that causes intoxication
Answer: A
Rationale: The DEC Program defines a drug as "any substance that, when taken into the
human body, can impair the ability of the person to operate a vehicle safely" .
5. Which phase of clinical trials primarily assesses a drug's safety and dosage in a small
number of healthy volunteers?
A. Phase I
B. Phase II
C. Phase III
D. Phase IV
Answer: A
Rationale: Phase I trials typically involve 20-80 healthy volunteers and focus on safety,
tolerability, and pharmacokinetics .
6. Which phase of clinical trials is designed to evaluate effectiveness and monitor side
effects in a larger patient population?
,A. Phase I
B. Phase II
C. Phase III
D. Phase IV
Answer: C
Rationale: Phase III trials involve large patient populations to confirm efficacy, monitor
side effects, and compare with standard treatments .
7. What is the purpose of a Phase IV post-marketing study?
A. To determine the chemical structure of a drug
B. To gather additional safety and efficacy data after approval
C. To test the drug in animals
D. To establish the starting dose for humans
Answer: B
Rationale: Phase IV studies are conducted after FDA approval to monitor long-term
safety, rare adverse effects, and effectiveness in real-world populations .
8. DRE stands for:
A. Drug Recognition Expert
B. Drug Rehabilitation Evaluator
C. Driving Risk Examiner
D. Deterrence and Roadside Evaluation
Answer: A
Rationale: DRE refers to a Drug Recognition Expert trained to identify impairment and
drug categories .
9. The primary purpose of a DRE evaluation is to:
A. Determine if a subject is impaired and by what drug category
B. Diagnose medical conditions
C. Prescribe treatment
D. Issue citations
Answer: A
Rationale: DREs assess impairment and form an opinion about the likely drug category .
10. According to the NHTSA/IACP DRE curriculum, DREs are certified to determine
which three things?
, A. (1) Whether the person is impaired, (2) whether this impairment is related to drug
impairment or a possible medical condition, and (3) if drug impaired, the category of
drug(s) most likely causing the impairment
B. (1) Blood alcohol concentration, (2) drug type, and (3) dosage
C. (1) Medical history, (2) prescription use, and (3) illegal drug use
D. (1) Impairment level, (2) legal status, and (3) treatment options
Answer: A
Rationale: Upon completion, DREs are certified to conduct a 12-step protocol to
determine whether the person is impaired, whether this impairment is related to drug
impairment or a possible medical condition, and if drug impaired, the category of
drug(s) most likely causing the impairment .
11. Which of the following is NOT a goal of the DRE program?
A. Identify impaired drivers
B. Diagnose medical conditions
C. Determine drug categories causing impairment
D. Assist in prosecution of drug-impaired driving cases
Answer: B
Rationale: DREs do not diagnose medical conditions. They determine whether
impairment is related to drug impairment or a possible medical condition, and if drug
impaired, the category of drug(s) most likely causing the impairment .
12. The DRE evaluation is conducted using:
A. A systematic and standardized procedure prescribed by the NHTSA/IACP DRE
curriculum
B. A flexible approach based on officer discretion
C. A single-step breath test
D. A medical examination protocol
Answer: A
Rationale: DREs shall conduct drug influence evaluations using a systematic and
standardized procedure as prescribed by the NHTSA/IACP DRE curriculum to ensure
that the 12-step process is adhered to for determining possible drug impairment .
13. The DRE protocol consists of how many steps?
A. 5
B. 8
