Affirmed

Summary

Layne Jex sustained back injuries in a rollover accident while driving home from work in his personal vehicle. He claimed workers’ compensation benefits under the instrumentality exception to the going and coming rule, arguing that his vehicle became an instrumentality of his employer’s business because he transported coworkers, carried tools, and ran errands. The Utah Labor Commission denied benefits.

Analysis

In Jex v. Labor Commission, the Utah Supreme Court clarified the standards for when an employee’s personal vehicle becomes an “instrumentality” of the employer’s business under workers’ compensation law, addressing an important exception to the going and coming rule.

Background and Facts

Layne Jex worked as a heavy equipment operator for Precision Excavating. When work moved from St. George to Cedar City, employees were responsible for their own transportation, though the company provided a designated meeting spot and sometimes a company truck. Jex drove his personal pickup truck most days, using it to transport coworkers, carry personal tools and hydraulic fluid, and run occasional errands for the company. While driving home from work, Jex sustained back injuries in a rollover accident and filed for workers’ compensation benefits.

Key Legal Issues

The central question was whether Jex’s personal vehicle qualified as an “instrumentality” of his employer’s business, creating an exception to the going and coming rule that generally bars compensation for commuting accidents. Jex argued that because his vehicle provided various benefits to Precision, it became an all-purpose instrumentality, making his commute fall within the course of employment.

Court’s Analysis and Holding

The Utah Supreme Court affirmed the denial of benefits, rejecting Jex’s broad interpretation of the instrumentality exception. The court clarified that the exception requires both employer control and substantial benefit to the employer, not merely incidental benefit. The court found that Jex’s activities—giving rides to coworkers, carrying tools, and running errands—were largely voluntary “loose cooperation” rather than employer-mandated duties. While these activities provided some benefit to Precision, they were “sporadic, slight, and employee-initiated” without sufficient employer control.

Practice Implications

This decision establishes a clear two-factor test for the instrumentality exception: employer control and substantial benefit must both be demonstrated. Practitioners should focus on establishing actual employer requirements or mandates for vehicle use, not merely voluntary beneficial activities. The court also clarified that any “benefit of the doubt” presumption in workers’ compensation cases applies only after thorough legal and factual analysis, not as a thumb on the scales during initial evaluation.

Holding

An employee’s personal vehicle does not become an instrumentality of the employer’s business under the workers’ compensation going and coming rule exception unless both employer control and substantial benefit to the employer are demonstrated.

Standard of Review

Correctness for the court of appeals’ decision; mixed question of law and fact entitled to deference for the commission’s decision

Practice Tip

When asserting the instrumentality exception to the going and coming rule, establish both clear employer control over vehicle use and substantial benefits to the employer, as incidental benefits alone are insufficient.
