DRE Data Analysis & Reporting 3

Question 1

What is the primary purpose of maintaining a DRE case log or tracking database at the agency level?

Accepted Answer

To identify drug trends, evaluate training needs, and support resource allocation

Answer

Agency-level DRE databases aggregate evaluation data to identify substance trends, measure program effectiveness, and guide policy decisions.

Question 2

During data review, a supervisor notices that a DRE officer's evaluations consistently produce no opinion on drug category. What does this pattern MOST likely indicate?

Accepted Answer

Possible training deficiency or incomplete evaluations

Answer

Consistent failure to render an opinion suggests the officer may need remedial training or is not completing evaluations thoroughly.

Question 3

A DRE report shows horizontal gaze nystagmus (HGN) onset before 45 degrees but the officer opined CNS stimulant impairment. Why is this report data problematic?

Accepted Answer

HGN is a primary indicator of CNS depressants or inhalants, not stimulants

Answer

Early HGN onset is associated with CNS depressants, dissociative anesthetics, and inhalants — its presence in a stimulant opinion creates an internal inconsistency.

Question 4

When a DRE officer submits a urine sample for toxicological analysis, which information is MOST critical to include on the chain of custody form?

Accepted Answer

Date, time, collector identity, and seal integrity documentation

Answer

Chain of custody requires documenting who collected the sample, when, and that integrity seals were intact to ensure the sample is legally defensible.

Question 5

In DRE data analysis, a 'false positive' evaluation occurs when:

Accepted Answer

The officer opines drug impairment but toxicology is negative

Answer

A false positive in DRE evaluation means the officer concluded drug impairment was present but toxicological analysis found no impairing substance.
