FAQ

Is Wisconsin a no-fault state?

No. Wisconsin is an at-fault state. The driver who causes an accident is responsible for damages. Wisconsin uses modified comparative negligence with a 51% bar — if you're less than 51% at fault, you can recover damages reduced by your percentage of fault.

Penalties include $10 fine for first offense (if no accident), license suspension until proof provided, $60 reinstatement fee, and SR-22 requirement for repeat offenses. Penalties increase significantly if you're involved in an accident while uninsured.
