6. Uninsured/Underinsured Motorist (UM/UIM) Coverage
What it pays: Your expenses from an accident caused by an uninsured motorist, a motorist who did not have enough insurance, or a hit-and-run driver. Also pays for personal property that was damaged in your car.
There is a mandatory $250 deductible for property damage. This means you must pay the first $250 of the expenses yourself before the company will pay.
There are two types of UM/UIM coverage:
Bodily injury UM/UIM pays for medical bills, lost wages, pain and suffering, disfigurement, and permanent or partial disability. There is not a deductible with this type.
Property damage UM/UIM pays for auto repairs, a rental car, and damage to items in your car.
