Insurance system in Wisconsin
Wisconsin is a fault (tort) state: the driver who caused the crash, through their liability insurance, pays for the other people's injuries and damage.
- System
- Fault (tort)
- PIP, benefits and when you can sue
- No PIP. The at-fault driver's liability insurance pays for others' injuries and damage. Insurers must offer medical payments coverage (minimum $1,000 if you take it), but you can decline it (OCI).
