BREAKING DOWN 'Uninsured Motorist Coverage-UM'. An uninsured motorist is one who has no insurance, does not have insurance that meets state-required minimum liability amounts, or whose insurance company is unwilling or unable to pay the claim. A hit-and-run driver would also be considered an uninsured motorist. Without this coverage, a person holding a regular automobile insurance policy may not receive payments if they are involved in an accident where the other party is at fault and uninsured.
