Detailed Answer

When a driver runs a red light and causes a collision in Utah, you must show four core elements of negligence: duty, breach, causation, and damages. Utah law requires all drivers to obey traffic-control signals. Under Utah Code § 41-6a-305, a driver facing a steady red signal must stop at the marked line or before entering the intersection (U.C.A. 41-6a-305).

Here’s how to prove each element:

1. Duty and Breach

  • Show the other driver had a duty to obey the red light under U.C.A. 41-6a-305.
  • Prove they breached that duty by running the red light. Use evidence such as:
    • Traffic camera or dashcam video timestamps.
    • Photos of the signal showing a red light at the moment of entry.
    • Official police or traffic collision report stating signal violation.

2. Causation

  • Link the breach directly to your crash. Identify:
    • Point of impact matching the intersection path.
    • Skid marks or debris indicating evasive maneuvers.
    • Expert reconstruction diagrams.

3. Damages

  • Document physical injuries, vehicle damage, and lost wages.
  • Use medical records and repair estimates.

Gathering and Preserving Evidence

Follow these steps immediately after the collision:

  • Call law enforcement and obtain a copy of the police report.
  • Take photographs of the scene, traffic lights, road markings, and vehicle positions.
  • Collect witness names, contact information, and written statements.
  • Retrieve video footage from traffic cameras or nearby businesses.
  • Keep all medical bills, repair estimates, and receipts.

Legal Standards in Utah

Utah applies a pure comparative negligence rule. Under U.C.A. 78B-5-818, you can recover damages even if you share some fault. The court reduces your recovery by your percentage of fault. Ensure your evidence clearly shows the red-light runner was primarily at fault.

Helpful Hints

  • Act quickly: evidence can disappear, cameras get overwritten, and memories fade.
  • Hire a qualified accident reconstruction expert to support causation.
  • Review your own actions to minimize comparative negligence.
  • Request all video recordings under Utah’s Government Records Access and Management Act (GRAMA).
  • Keep a detailed incident diary while preparing your claim.

By following these steps and citing the applicable Utah traffic statutes, you can build a strong case to prove another driver’s liability after a red-light collision.
