Summary

The juvenile challenged the admission of police officer testimony as improper expert testimony and argued insufficient evidence supported the reckless driving determination.
Practice Areas & Topics
Analysis
In In re A.D.-C., the Utah Court of Appeals addressed when police officer testimony about vehicle accidents constitutes improper expert testimony versus admissible lay opinion testimony in juvenile delinquency proceedings.
Background and Facts
A 16-year-old juvenile with only a learner’s permit borrowed his father’s Cadillac Escalade and crashed after attempting a left turn at excessive speed. The vehicle rolled over and came to rest in a residential backyard after crashing through a fence. Police officers responded and observed extensive damage, skid marks, and yaw marks on the pavement. The State charged the juvenile with reckless driving and driving without a license. At trial, defense counsel objected to portions of the officers’ testimony as improper expert testimony that had not been disclosed.
Key Legal Issues
The court addressed two primary issues: (1) whether the officers’ testimony about the accident reconstruction and yaw marks constituted improper expert testimony, and (2) whether sufficient evidence supported the reckless driving adjudication under Utah Code § 41-6a-528.
Court’s Analysis and Holding
The court applied the test from State v. Rothlisberger, determining whether testimony requires specialized knowledge or whether “an average bystander would be able to provide the same testimony.” The court held that Officer 1’s basic observations about how a vehicle could end up facing the wrong direction in a yard were within the ken of the average bystander. Most people have sufficient experience with car travel to offer basic opinions about accident causation based on observations of damage patterns and positioning.
Regarding Officer 2’s testimony about yaw marks, the court assumed without deciding that this may have constituted expert testimony but found any error harmless. The overwhelming evidence of excessive speed and loss of control made any improper yaw mark testimony non-prejudicial.
On sufficiency of evidence, the court affirmed on alternative grounds, finding the juvenile operated his vehicle in willful or wanton disregard for safety by attempting a 90-degree turn at 45 miles per hour, creating obvious risks to persons and property.
Practice Implications
This decision provides guidance on the lay witness versus expert testimony distinction in vehicle accident cases. Practitioners should focus objections on whether officer testimony requires specialized technical knowledge beyond common experience. Basic observations about accident causation based on damage patterns and vehicle positioning generally qualify as permissible lay opinion testimony under Utah Rule of Evidence 701.
