Is expert testimony required to prove construction zone negligence? United Fire Group v. Staker and Parson Companies Explained

The Utah Court of Appeals addressed a critical question about when expert testimony is required in construction zone negligence cases in United Fire Group v. Staker and Parson Companies. The decision provides important guidance for practitioners handling personal injury claims involving construction zones.

Background and Facts

In October 2009, Scott and Brenda McDowell accidentally entered a construction zone on 12th Street in Ogden. Staker and Parson Companies was performing major construction work and had diverted westbound traffic to an eastbound lane. However, the McDowells entered the unfinished westbound lanes from an adjacent parking lot, where there were no barriers or warning signs. They drove a short distance on newly paved road before dropping into an unfinished section, sustaining injuries. United Fire Group, their insurer, paid medical bills and vehicle damage, then sued Staker as subrogee claiming negligent maintenance of the construction zone.

Key Legal Issues

The central issue was whether expert testimony was required to establish the standard of care for temporary traffic control and prove breach of that standard. Staker successfully moved for summary judgment in district court, arguing that United Fire could not establish a prima facie negligence case without expert testimony about traffic control standards.

Court’s Analysis and Holding

The Court of Appeals reversed, creating an important distinction. While expert testimony is generally required for temporary traffic control cases due to the technical complexity of UDOT’s 985-page Manual on Uniform Traffic Control Devices, the court found an exception applies when there is evidence of a complete absence of warning signs or safety devices. The court noted that “[n]o expert is required to determine that Staker should have given at least some warning about the dangerous road condition that it created.” However, if adequate warning devices were present and the issue became their sufficiency, expert testimony would be required.

Practice Implications

This decision provides a roadmap for construction zone negligence cases. Practitioners should focus on establishing evidence of complete absence of safety measures rather than challenging the adequacy of existing measures to avoid expert testimony requirements. The distinction between “no warning” and “inadequate warning” becomes crucial for summary judgment motions and case strategy.
