What is uninsured motorist (UM) coverage?

Quick answer: Pays your medical bills and lost wages when you are hit by an uninsured driver. Critical because about 1 in 8 US drivers is uninsured.

Uninsured motorist (UM) pays your medical bills and lost wages when you are hit by a driver with no insurance. Roughly one in eight US drivers is uninsured. Underinsured motorist (UIM) pays the gap when an at-fault driver does have coverage but their limits are not enough. An uninsured driver runs a red light and breaks your collarbone: UM pays your $35,000 hospital bill and lost income. Without UM, you would be chasing a likely-judgment-proof driver in court.
