No-fault insurance is an auto insurance system where, after an accident, each driver's own insurer pays for that driver's medical bills and certain expenses—regardless of who caused the crash. The goal is to get people paid quickly and to cut down on lawsuits over minor accidents. It's most associated with auto coverage, often through Personal Injury Protection (PIP).

Why it matters

In a traditional "fault" system, you have to prove the other driver was negligent before their insurer pays your injury costs, which can take months and end up in court. No-fault flips that: your own policy pays your medical expenses right away. Whether a state uses no-fault, a traditional fault (tort) system, or a hybrid varies by state, so treat this as a conceptual model.

A simple example

Two cars bump into each other on a snowy road. Both drivers have minor whiplash. In a no-fault state, each driver's own insurer pays that driver's medical bills through PIP, and they generally don't sue each other over those smaller injuries. Everyone gets treated and reimbursed without first arguing about blame.

Don't confuse it with…

No-fault does not mean "no one is ever responsible" or that you can't be sued. Most no-fault states keep a threshold: if injuries are severe enough (very serious injury or costs above a certain level), the injured party can step outside the no-fault system and sue the at-fault driver. No-fault also applies to injury costs—property damage to vehicles is usually still handled on a fault basis.

On the exam

Connect no-fault with PIP and the phrase regardless of fault. Know that no-fault is designed to reduce litigation and speed up payment, that it applies mainly to bodily injury, and that serious-injury thresholds let badly hurt people still pursue a lawsuit. Remember it's a state-by-state choice.
