In this area, catastrophic cases commonly come from two situations:
- High-impact roadway collisions (including multi-vehicle events where braking distance, lane changes, and vehicle maintenance are disputed).
- Worksite and equipment incidents (falls, struck-by events, and injuries involving malfunctioning tools or unsafe conditions).
In both settings, insurers often focus on early uncertainty—such as whether symptoms will improve or whether the injury was caused by something else. A serious case usually requires proving:
- The injury is severe and will affect function long-term
- The incident caused the injury (not a pre-existing condition or unrelated event)
- The losses are not limited to emergency care—future treatment, home support, and earning capacity can be at stake
