Phoenix, AZ Drug Recognition Experts on the Frontline of Drug DUIs

by Aaron Black • January 30, 2020
Drug impaired drivingWhile society waits for researchers to develop a machine to detect drugs in impaired driving cases, Arizona and as well as all other states rely on specially trained police officers known as drug recognition experts (DRE), to do the task.

The DRE concept was developed in the 1970s in Los Angeles, which gained the attention of the National Highway Traffic Safety Administration (NHTSA) in the early 1980s. They developed a protocol for a standardized DRE. The agencies determined that a trained DRE can identify someone who is impaired by drugs and accurately determine the category of drugs involved.

The NHTSA in 2013-14 conducted a National Roadside Survey and reported that 20 percent of drivers who were surveyed tested positive for “potentially impairing drugs.”

Arizona became part of the NHTSA’s Drug Evaluation and Classification (DEC) pilot program in 1987 and now the DEC program is used by all the states.

The thing is, however, that people and machines are not infallible.

Invalid Drug DUI Arrests Happen!

According to an ABC 15 TV news report, sober drivers are being arrested for drug impairment in Phoenix, AZ. One DRE officer arrested at least nine people whose cases were dismissed for lack of evidence. For example, in July and September 2019 two motorists were arrested for drug-impaired driving.

In the July case, a woman was stopped for allegedly failing to obey a stop sign and a DRE officer noticed she had “eyelid tremors,” she didn’t perform well on the field sobriety test and was suspected to be on drugs. Tests proved she hadn’t been taking any drugs that police tested for, such as marijuana.

In a September case, a 63-year-old man driving home from work on Labor Day night was stopped for allegedly crossing a lane line and his performance in a field sobriety test revealed he had poor balance, bloodshot watery eyes, and slurred speech, the defense countered, because of missing teeth and a New York accent. Based on those observations the DRE officer made the unlawful arrest.

One drug DUI defendant only had heartburn medication in his system and several other examples of DRE arrests weren’t valid, the news report stated.

Qualifying for DRE Training

A law enforcement officer who wants to enter the DRE program must satisfy four requirements.

The officer needs to…
  • Have three years of law enforcement training, although that criteria can be waived
  • Submit an application through their present supervisor or a DRE coordinator of the DRE Advisory Committee
The candidate will be judged upon a…
  • History of good conduct and service in law enforcement
  • Lastly, the candidate must submit to the DRE Advisory Committee a copy of the progress log for the standard field sobriety test and a certificate of the Advanced Roadside Impaired Driving Enforcement (ARIDE)

Arizona’s DRE Training Program

Training law enforcement officers to detect someone who is impaired by drugs is a three-phase program consisting of 88 hours of instruction.
  • Phase 1 is a DRE pre-school lasting 16 hours in which the candidate officer learns drug evaluation techniques, procedures, and strategies.
  • Phase 2 gives the candidate comprehensive instructions on how to evaluate the drug examination, physiology, the various effects drugs have and the legal considerations that come into play. After the classroom instruction is finished the candidate takes a written test.
  • Phase 3 is the field certification lasting for 60 to 90 days. During this phase, the candidate learns to evaluate a person who is suspected of driving while impaired by drugs and alcohol and is supervised by a certified instructor. At least 12 drug DUI evaluations must be performed. After that is a comprehensive exam.
When these phases are finished the candidate is certified as a DRE officer but must be recertified every two years.

Phoenix currently has 26 DRE certified officers.

Probable Cause & a DRE Evaluation

Before a traffic officer can detain a driver the officer must have probable cause, meaning that the officer suspects the driver is impaired or has witnessed the driver breaking a traffic law.

The officer will want to conduct a breathalyzer test, and if an illegal blood-alcohol concentration (BAC) is under the legal 0.08 percent a DRE officer will be summoned to conduct an evaluation.

The DRE officer looks for signs of illicit or prescription drug impairment, including the size of the pupils, pulse rate, muscle tone tightness or flaccidity, needle injection sites, and interrogating the driver to help determine the type of drug and a toxicology test.

The driver may refuse to participate in the breathalyzer and the DRE evaluation at the cost of a license suspension or revocation.
