The Role of Drug Recognition Experts in DUI Cases: What You Need to Know

While most people are familiar with the concept of driving under the influence (DUI) of alcohol, many might not be aware that drug-impaired driving is an equally important concern in Brampton and across Canada. Law enforcement agencies have developed methods for detecting drug-impaired drivers, including the use of Drug Recognition Experts (DREs) to conduct specialized evaluations. As a driver in Brampton, it is vital to understand the role of DREs in drug-related DUI cases and how their analysis could influence your legal defence strategy.

In this blog article, we will discuss the critical role of DREs in such cases, including information on their training, the evaluation process, and the potential impact their findings can have on your legal defence.

Understanding Drug Recognition Experts

Drug Recognition Experts (DREs) are law enforcement officers who have undergone specialized training to identify individuals driving under the influence of drugs. Developed by the International Association of Chiefs of Police (IACP) and the Royal Canadian Mounted Police (RCMP), the DRE program seeks to equip officers with the knowledge and skills needed to perform thorough drug impairment evaluations. These evaluations involve a series of steps designed to establish whether a driver is impaired by drugs, and, if so, what category of drugs may be responsible for the impairment.

The Significance of DRE Training and Certification

To become a certified Drug Recognition Expert, a law enforcement officer must complete a rigorous training program. The program, which includes both classroom instruction and practical application, covers various topics such as drug pharmacology, standardized field sobriety testing, and vital signs assessment. Upon successful completion of the training, the officer must pass a written examination and receive certification from the IACP.

This training and certification process is essential for maintaining the credibility of the DRE program and ensuring that evaluations are conducted accurately. Properly trained DREs have the ability to provide reliable testimony in court, which can carry significant weight in drug-impaired driving cases.

The DRE Evaluation Process

When a driver is suspected of being under the influence of drugs, they may be subject to a DRE evaluation. This evaluation consists of a 12-step process, which includes the following:

  1. Breath Alcohol Test: The officer will first administer a breath test to determine if alcohol is contributing to the observed impairment.
  2. Interview with Arresting Officer: The DRE will gather information from the arresting officer regarding the suspect’s behaviour, appearance, and driving.
  3. Preliminary Examination: The DRE will observe the suspect for signs of drug impairment, including poor coordination, lack of focus, and slurred speech.
  4. Eye Examination: The DRE will check for abnormalities in the suspect’s eye movements and pupil size.
  5. Divided Attention Tests: The DRE will administer a series of psychophysical tests designed to assess the suspect’s ability to multitask and maintain balance.
  6. Vital Signs Examination: The DRE will measure the suspect’s blood pressure, pulse, and body temperature to identify potential drug-induced effects.
  7. Dark Room Examinations: The DRE will examine the suspect’s pupils in varying light conditions to detect drug-induced changes.
  8. Examination for Muscle Tone: The DRE will assess the suspect’s muscle tone, as certain drugs can cause muscles to become rigid or flaccid.
  9. Injection Site Examination: The DRE will check for evidence of recent drug injections.
  10. Interrogation and Statements: The DRE will ask the suspect about their drug use and behaviour leading up to the incident.
  11. Opinion of the Evaluator: Based on the assessment, the DRE will form an opinion on whether the suspect is impaired by drugs and what category of drugs may be responsible.
  12. Toxicological Sample: The suspect may be required to provide a urine, blood, or saliva sample for laboratory analysis to confirm the presence of drug(s).
Impact of DRE Findings on Your Legal Defence

The findings and testimony of a DRE can carry significant weight in court, impacting the outcome of your case. A DRE’s opinion, supported by their training and certification, can corroborate other evidence presented by the prosecution. As such, it is crucial to have an experienced criminal defence lawyer who is well-versed in the DRE process and can effectively counter such testimony. Your legal defence may involve challenging the DRE’s evaluation process, questioning their qualifications, or presenting alternate explanations for the signs of impairment observed.
