Utah Court of Appeals
Can prescription drug use support a DUI conviction in Utah? State v. Salgado Explained
Summary
Salgado was convicted of DUI and interference with an arresting officer after an extended traffic stop where she failed to respond to police signals while driving slowly with hazard lights on. The officer observed droopy eyelids, confusion, and poor performance on field sobriety tests, leading to her arrest for driving under the influence of tramadol, a prescribed medication.
Analysis
In State v. Salgado, the Utah Court of Appeals addressed whether the State presented sufficient evidence to support a DUI conviction based solely on prescription drug impairment, without expert testimony establishing specific concentration levels or impairing effects.
Background and Facts
During a patrol on I-15, a highway patrol officer observed Salgado driving significantly below the speed limit with hazard lights activated, creating a traffic hazard. Despite multiple attempts to get her attention—including activating emergency equipment, using sirens, and positioning his vehicle alongside hers—Salgado failed to respond and continued driving for an extended period. When finally stopped, the officer noticed droopy eyelids and confusion. Salgado admitted to taking four medications that morning, including tramadol, a central nervous system depressant. Field sobriety tests revealed twelve out of eighteen possible impairment clues, and subsequent chemical testing confirmed tramadol’s presence in her system.
Key Legal Issues
Salgado challenged her conviction on three grounds: (1) insufficient evidence of impairment, arguing the State’s expert could not establish that her tramadol levels created impairing effects; (2) improper jury instructions that allegedly commented on the evidence by emphasizing certain impairment factors; and (3) the trial court’s refusal to instruct on minimum-speed violation as a lesser included offense.
Court’s Analysis and Holding
The court affirmed the conviction, finding sufficient evidence supported the DUI charge. While the State’s expert could not quantify impairment levels, the court held that eyewitness testimony from the trained officer, combined with unusual driving patterns and field sobriety test results, provided adequate proof. The court distinguished State v. Hechtle, noting that unlike that case, here the officer had significant training, observed behavior indicative of drug use, and conducted proper field sobriety tests. Regarding jury instructions, the court found any error in Instruction 18 was harmless because most factors applied to both drug and alcohol impairment, and Instruction 19 correctly stated that legal prescription use is not a defense to DUI if impairment renders one incapable of safe driving.
Practice Implications
This decision clarifies that Utah prosecutors need not present expert testimony establishing specific drug concentration levels to prove prescription drug DUI. Trained officer observations, driving patterns, and field sobriety test results can sufficiently establish impairment. For defense counsel, this case emphasizes the importance of challenging the foundation for officer testimony and exploring alternative explanations for observed behaviors. The decision also confirms that taking medication as prescribed provides no defense if the medication impairs driving ability.

Court
Utah Court of Appeals
Case Number
No. 20160104-CA
Date Decided
July 12, 2018
Outcome
Affirmed
Holding
The State presented sufficient evidence to support a DUI conviction based on prescription drug impairment, and the trial court properly instructed the jury and correctly denied the lesser included offense instruction request.
Standard of Review
The court applied different standards for different issues: sufficiency of evidence challenges are reviewed by examining evidence in the light most favorable to the verdict and reversing only when evidence is sufficiently inconclusive that reasonable minds must have entertained reasonable doubt; jury instruction challenges present questions of law reviewed for correctness, though precise wording is left to the trial court’s sound discretion; and lesser included offense instruction denials are reviewed for correctness as questions of law.
Practice Tip
When challenging DUI convictions based on prescription drug impairment, focus on the adequacy of evidence showing actual impairment rather than merely the presence of drugs in the system, as Utah law requires proof of incapacity to safely operate a vehicle.
