When does negligent driving proximately cause injuries to emergency responders? Dee v. Johnson Explained

The Utah Court of Appeals addressed the challenging question of proximate cause in traffic accident cases involving emergency responders in Dee v. Johnson. This decision provides important guidance on when the causal chain between negligent driving and subsequent injuries becomes too attenuated to support liability.

Background and Facts

Johnson was driving eastbound on I-84 when road conditions became slick with snow and ice. He lost control and slid into the median, then called the Utah Highway Patrol for assistance. A tow truck arrived within twenty minutes and pulled Johnson’s car onto the highway, partially blocking the left lane. Other vehicles began losing control in the icy conditions, and Dee’s vehicle collided with the tow truck, causing severe injuries to Dee.

Key Legal Issues

The central issue was whether Johnson’s negligent driving proximately caused Dee’s injuries. Johnson admitted negligence but argued his conduct was not the proximate cause of the collision with the tow truck. The court reviewed the summary judgment ruling for correctness, noting that summary judgment in negligence cases is appropriate only in the clearest instances.

Court’s Analysis and Holding

The court applied Utah’s proximate cause test, requiring a cause that “in a natural and continuous sequence, unbroken by any new cause, produced the injury.” The court emphasized that foreseeability focuses on “whether the specific mechanism of the harm could be foreseen,” not general risks. Here, the court found the causal separation too great—Johnson’s car safely came to rest in the median, and the collision occurred only after multiple intervening acts including the highway patrol response and tow truck placement.

Practice Implications

This decision demonstrates that proximate cause analysis requires examining the specific sequence of events, not just but-for causation. Practitioners should distinguish cases where defendant’s negligence immediately creates a highway hazard from those involving multiple intervening causes. The court’s emphasis on foreseeability of specific mechanisms rather than general risks provides a framework for analyzing complex causal chains in traffic accident cases.
