After a car crash, more than one insurance policy may apply. 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. An auto accident lawyer usually requests the declarations page for every policy that might apply, because the coverage often decides how much of a loss can be paid.
How fault rules shape coverage
Most states require drivers to carry a minimum amount of liability insurance, which covers injuries and property damage the insured driver causes to others. Minimum limits are often 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, where each driver's own PIP coverage pays medical expenses and some lost income regardless of who caused the crash. In those states, a lawsuit against the at-fault driver may be limited unless the injury meets a legal threshold.
PIP and MedPay coverage
PIP is required in no-fault states and in a few other states, 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, often called MedPay, is a separate and usually smaller coverage. It pays medical expenses for the policyholder and passengers regardless of fault, up to its policy limit. A car accident attorney will check whether these benefits require prompt notice or a written claim.
When the other driver has little or no insurance
Uninsured motorist (UM) coverage applies when the at-fault driver 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 are too low to cover 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, 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. Many policies require prompt notice, and hit-and-run claims may depend on a timely police report. Some states require that the UM insurer be served with a copy of the lawsuit against the at-fault driver. An auto accident lawyer will check these requirements early, since a missed step can put coverage at risk.
Vehicle damage coverage
Collision coverage pays to repair or replace the policyholder's car regardless of fault, minus the deductible. The insurer may then seek repayment from the at-fault driver's insurer through subrogation, and the deductible is sometimes recovered too. Gap insurance and rental reimbursement are optional coverages that can matter https://finneygj547.moderncairn.com/posts/choosing-a-car-accident-lawyer-questions-to-ask after a total loss.
Health insurance and liens
Health insurance, Medicare or Medicaid may pay medical bills first and later claim 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.
