No-fault insurance is a type of car insurance that mandates coverage for medical expenses and other losses regardless of who is at fault in an accident. This system is designed to reduce the number of small and frivolous lawsuits that often arise from automobile accidents by allowing individuals to receive compensation from their own insurance providers for injuries and damages sustained, without the need to prove fault.
The most accurate response from your options would be:
"Unlimited PIP mandated by the states to reduce the number of small and frivolous lawsuits."
(Note: PIP stands for Personal Injury Protection, which is a key component of no-fault insurance.)
