What a DUI Drug Recognition Evaluation Is
Drug DUI cases need proof of impairment, not just detection. A DUI drug recognition evaluation is one kind of officer observation that may appear in that proof. Because the Vehicle Code does not define the exam, the record in each case shows what the officer actually did.
So the paperwork matters. Reading it closely helps a person understand the evidence.
Why Officers Rely on Observations
Vehicle Code section 23152 subdivision (f) bars driving under the influence of any drug. Unlike the 0.08 percent rule for alcohol in subdivision (b), the statute sets no per se blood level for drugs. Therefore, a drug case depends on evidence that the drug affected driving.
Officer observations are one source of that evidence. A DUI drug recognition evaluation is offered as a record of those observations.
Questions About What the Exam Covered
The statute does not list the steps of the exam. So ask for the full evaluation form and any notes. Then ask what each step involved and in what order it happened.
Also ask what training the officer completed and whether training records exist. In addition, ask whether the report records any statements about recent use.
DUI Drug Recognition Evaluation and Chemical Tests
Vehicle Code section 23612 addresses chemical testing for drug content after a lawful arrest. It also says a person must submit to urine testing if blood testing is unavailable. So a drug case may include both an evaluation and a lab result.
Compare the two closely. The guide on DUI toxicology testing explains the lab side.
Questions About the Evaluation
Ask when the evaluation took place and how long it lasted. Also ask whether medical conditions, fatigue or injuries could explain any signs. Then compare the officer’s notes with video if available.
The article on field sobriety medical limitations covers how health issues affect tests. Meanwhile, the guide on drug detection versus impairment explains the limits of lab results.
Records and Timing
The California Office of Traffic Safety runs statewide traffic safety programs. A lawyer can request evaluation and training records through discovery, and an expert may then review them.
Timing also deserves a close look. For example, compare the times on the evaluation form with the arrest report and the blood draw record. So any gap between driving and the exam becomes clear in a DUI drug recognition evaluation review.
