More than one insurance policy can apply after a car crash. People usually think first of the at-fault driver's liability coverage, but personal injury protection (PIP), MedPay and uninsured motorist (UM) coverage can matter just as much. A car accident lawyer usually requests the declarations page for every policy that might apply, since coverage often decides how much of a loss can be paid.
How fault rules shape coverage
Most states require drivers to carry minimum liability insurance, which pays for 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 at-fault states, the injured person generally claims against the at-fault driver's insurer. Some states use a no-fault system, in which each driver's own PIP coverage pays medical expenses and some lost income regardless of fault. No-fault states may restrict lawsuits against the at-fault driver unless the injury meets a legal threshold.
PIP and MedPay
No-fault states require PIP, and a few other states do as well, while some states offer it as an option. Depending on the policy, it can pay medical bills, part of lost wages and certain household expenses. Medical payments coverage, usually called MedPay, is separate and generally smaller. It pays medical expenses for the policyholder and passengers regardless of fault, up to its policy limit. An auto accident attorney will check whether these benefits require prompt notice or a written claim.
Uninsured and underinsured motorist coverage
Uninsured motorist (UM) coverage applies when the at-fault driver has no insurance, and in many states it also covers 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, while others allow it to be rejected 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, but in that claim the insurer takes the position of the uninsured driver, which means it can contest fault and the value of the claim. Policies often require prompt notice of https://telegra.ph/What-a-Car-Accident-Lawyer-Looks-at-After-a-Rear-End-or-T-Bone-Crash-11-09 the claim, and a hit-and-run claim may require a timely police report. In some states, the UM insurer must be served with a copy of any lawsuit against the at-fault driver. A car crash attorney usually checks these steps early, since a missed step can put coverage at risk.
Repairs and rentals
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. An automobile 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.
