DRE

DRE stands for a “drug recognition evaluator.” DRE’s are frequently called upon to differentiate between drug influence and medical and/or mental disorders. The certified DRE is an tool for combating the adverse impact of drug and alcohol-impaired driving.

Although DRE school used to be more demanding, the requirements have been watered down over the years so that more officer qualify.

The International Association of Chiefs of Police (IACP) is the regulating and certifying organization for the DRE program. DRE certification is valid for two years. In order to maintain certification, DRE’s must conduct a minimum of four evaluations within the two years, submit a rolling log and current curriculum vitae, and attend eight hours of recertification training.

If an DRE is involved in your DUI case, your criminal defense attorney should file motions to exclude that testimony at trial.

Is the DRE Evidence Admissible?

In some cases, the DRE evidence is admissible. As a general rule, the courts have found that the Frye test does not apply to DRE evidence because the general portion of the DRE protocol is not scientific. The DRE protocol consists of a twelve step systematic assessment of the defendant’s vital signs and physical appearance, a physical examination, as which as other parts of the typical DUI investigation, including the standard field sobriety tests.

The physical examination of the DRE involves some techniques borrowed from the medical field, including:

  • measuring pupil size;
  • observing pupil reaction to light;
  • taking blood pressure and pulse rate;
  • inspecting the oral and nasal cavities; and
  • touching the arm to determine muscle tone.

Since the tests, signs and symptoms of the protocol are within the common understanding of the average layman, the general portion of the protocol are not “scientific” within the meaning of Frye. The components of the DRE testing protocol include:

  • breath alcohol test;
  • interview of the arresting officer;
  • preliminary examination and first pulse;
  • eye examination;
  • divided attention psychophysical tests;
  • vital signs and second pulse;
  • dark room examinations;
  • examination for muscle tone;
  • check for injection sites and third pulse;
  • suspect’s statements and other observations;
  • opinions of the evaluator; and
  • toxicological examination.

The fact that some of the examinations in the protocol are borrowed from the medical profession does not elevate the protocol to scientific status. Williams v. State, 710 So.2d 24 (Fla. 3d DCA 1998).

The DRE protocol is based on the fact that the consumption of alcohol and/or drugs produces readily observable and distinguishable psychophysical signs and symptoms.


Two Phases of Training to Become a DRE

According to the application for the FLORIDA DRUG RECOGNITION EXPERT SCHOOL, to receive certification as a DRE, two phases of training must be completed:

  • ACADEMIC TRAINING:
    • The academic training phase is typically conducted over nine days (for a total of 72 hours of training).
    • The training includes covering topics in physiology, vital signs, standardized field sobriety testing (SFST), as well covering material on each of the seven categories of the drugs of abuse.
    • The training includes two written examinations, an SFST proficiency examination and five written quizzes.
    • Students must achieve a minimum of 80% on the two examinations (Pre-School Post Test & DRE School Post Test) and must demonstrate proficiency in administering SFST’s in order to progress to the next stage of training.
    • Students who cannot successfully pass this testing cannot continue in the program.
  • CERTIFICATION PHASE:
    • After successfully completing the academic portion, the students must complete the certification phase.
    • The student is responsible for completing the certification requirements within three months following the DRE school.
    • These requirements include conducting a minimum of 12 drug influence evaluations while under the supervision of a DRE instructor, identifying subjects under the influence of three of the seven drug categories, and attaining a 75% toxicological confirmation rate.
    • In addition, the student must maintain a progress log, rolling log and submit a curriculum vitae.
    • Finally, the student must pass a comprehensive final knowledge examination, and obtain the written endorsement of two certified DRE instructors.
