More than one insurance policy can apply after a car crash. The at-fault driver's liability coverage is usually the first source people think of, but personal injury protection (PIP), MedPay and uninsured motorist (UM) coverage can matter just as much. A car accident lawyer will usually ask for the declarations page of every policy that might apply, since coverage often decides how much of a loss can be paid.
At-fault and no-fault states
Most states require drivers to carry a minimum amount of liability insurance, which covers injuries and property damage the insured driver causes to others. State minimum limits can be low compared with the cost of a serious injury. In an at-fault state, the injured person usually makes a claim against the at-fault driver's insurer. A smaller group of states uses a no-fault system, where each driver's own PIP coverage pays medical expenses and some lost income regardless of who caused the crash. No-fault states may restrict lawsuits against the at-fault driver unless the injury meets a legal threshold.
PIP and MedPay coverage
No-fault states require PIP, and a few other states do as well, and some others offer it as an option. Depending on the policy, it may cover medical bills, a share of lost wages and some household expenses. Medical payments coverage, usually called MedPay, is separate and generally smaller. The coverage pays medical expenses for the policyholder and passengers no matter who caused the crash, up to the limit on the policy. A car accident attorney will check whether these benefits require prompt notice or a claim form.
Uninsured and underinsured motorist coverage
Uninsured motorist (UM) coverage pays for injuries caused by a driver who has no insurance, and many states extend it to hit-and-run crashes. Underinsured motorist (UIM) coverage applies when the at-fault driver's limits fall short of the loss. Some states require UM coverage, and others let a policyholder reject it in writing. Rules on stacking coverage from more than one vehicle or policy also vary. A relative's policy in the same household may also provide UM coverage in some states.
Making a UM claim
A UM claim is made to the injured person's own insurer, yet in that claim the insurer stands in the shoes of the uninsured driver, so it may dispute fault and the amount of damages. Many policies require prompt notice, and a hit-and-run claim may require a timely police report. In https://cesarjiky564.focalledger.com/posts/choosing-a-car-accident-lawyer-questions-to-ask some states, the UM insurer must be served with a copy of any lawsuit against the at-fault driver. A car accident attorney will check these requirements early, because missing one can affect the coverage.
Vehicle damage coverage
Collision coverage pays for repairs to the policyholder's car regardless of fault, less the deductible. The insurer can then seek repayment from the at-fault driver's insurer through subrogation, which can sometimes recover the deductible as well. Rental reimbursement and gap insurance are optional coverages that can matter after a total loss.
Health insurance and liens
Medicare, Medicaid or a health plan may pay medical bills first and later seek repayment from a settlement. A car accident lawyer will usually resolve those liens before any money is distributed. Coverage rules vary by state and by policy, and this article is general information, not legal advice.
