What’s Uninsured/Underinsured Motorist (UM/UIM) insurance and how does it work?

October 30, 2017

Uninsured Motorist (UM) and Underinsured Motorist (UIM) insurance is coverage under an injured person’s own auto policy.  UM/UIM insurance comes into play when the at-fault driver’s insurance limits aren’t enough to cover the injured person’s claim.  In Washington State, insurers must offer UM/UIM coverage equal to the amounts of the liability coverage purchased.  UIM/UM coverage can only be rejected in writing.
