Personal Injury Protection — Otherwise known as “PIP,” this is your medical coverage for injuries you (and others) suffer in an auto accident. PIP pays if you or other persons covered under your policy are injured in an auto accident. It is sometimes called “no-fault” coverage because it pays your own medical expenses no matter who caused the auto accident. The purpose of No-Fault insurance is to ensure that someone who is hurt in an auto accident is able to return to health and productivity as quickly as possible.
