Definition and Core Purpose
Uninsured motorist (UM) auto insurance is a supplemental coverage that pays for your injuries and, in some states, property damage when the at‑fault driver has no insurance or cannot be identified. It essentially steps in as a fallback when the responsible party cannot meet their liability.

Key Benefits
UM coverage ensures you receive medical expense reimbursement, lost‑wage compensation, and pain‑and‑suffering damages without waiting for a lawsuit to resolve. In states that allow it, it also covers damage to your vehicle, known as uninsured motorist property damage (UMPD).
How It Works
When you file a claim, the insurer evaluates the accident to confirm the other driver lacks coverage. If verified, your UM policy pays up to the limits you selected, subject to any deductible. If the at‑fault driver is later found to have insurance, your insurer may seek reimbursement through subrogation.
State Variations
Requirements and available benefits differ by state. Some mandate a minimum UM limit, while others treat it as optional. Certain jurisdictions combine UM and underinsured motorist (UIM) coverage into a single policy provision.
Choosing Coverage Limits
Selecting limits comparable to your bodily injury liability protects you from out‑of‑pocket costs. Common limits range from $25,000/$50,000 to $100,000/$300,000 per person and per accident.
